Current Status of Greenhouse Tomato Production in Aksu Area of Southern Xinjiang

With the implementation of the "13^(th) Five-Year Plan" to promote the border area and raise rural living standards, the Xinjiang Production and Construction Corps has paid more and more attention to the development of protected agriculture, which is needed for the comprehensive development and stability of the border groups. In this paper, the current status of greenhouse tomato production in Aksu of southern Xinjiang is analyzed and summarized, finding the following: the structure is not reasonable with poor performance; the soilless cultivation mode is gradually developed, and there are innovative forms; the fertilization structure is not reasonable and needs improvement; the technical level is low, and it needs to be upgraded. Therefore, to solve the various problems that exist at present, some efforts are needed achieve a better production model.

Adjusted Nutrition Solution Formula Improves the Growth and Yield of Soilless Tomato Culture in Southern Xinjiang

The tomato production facilities in southern Xinjiang have unique climatic conditions.However,due to the high salinity and degree of mineralization of the soil and the extensive management of irrigation water sources,the tomato production efficiency is low,and there is still much room for improvement.In this study,the formulas of tomato nutrient solutions were adjusted according to the local irrigation water quality characteristics,and tomato was grown in a greenhouse using sand cultivation.To select a nutrient solution formula suitable for the tomato cultivated in the local facilities,various parameters of tomato treated with different formulas were compared.The results showed the following:①Adjusting the nutrient solution formula could effectively improve the vegetative and reproductive growth indexes of tomato.②Properly decreasing the nutrient solution concentration could improve the growth indexes of tomato.③Decreases in Ca^(2+) and Mg^(2+) in the nutrient solution did not affect the growth and yield of tomato.The possible reason for the third result was that excessive cations in the water inhibited the absorption of Ca^(2+) and Mg^(2+) in the nutrient solution and had antagonistic effects.Therefore,a high nutrient solution concentration does not necessarily promote the growth of tomatoes.In summary,this study will improve the production conditions of protected tomato in the southern Xinjiang area by supporting tomato nutrient solution adjustments according to actual conditions in combination with reasonable irrigation systems and scientific management.

A Study on Urban Forms of Prefectures in the Ming and Qing Dynasties in Southern Hebei and Their Influencing Factors

The prefectures of Ming and Qing Dynasties in southern Hebei had profound historical heritage and rich urban forms.Studying their morphological characteristics can provide a scientific basis for city construction under the background of cultural self-confidence.In this paper,we conducted an urban survey on prefectures in the Ming and Qing Dynasties in southern Hebei by collecting historical documents such as ancient maps and local chronicles since the Ming and Qing Dynasties,comprehensively using typological methods.The influencing factors of urban spatial forms were further discussed from three aspects:political and military defense,etiquette and geographical environment,and culture and economic development.

Zircon U-Pb Dating of Yushugou Terrain of High-Pressure Granulite Facies in Southern Tianshan Mountain and Its Geological Significance

The Yushugou terrain of high\|pressure granulite facies in southern Tianshan Mountain is composed mainly of an ophiolite suite. Most selected zircons are round or elliptical in shape, and some are of tetragonal prism with round edges. The granulometric analyses show that they are well sorted in sedimentation. ZrO\-2/HfO\-2 ratios in zircons range from 45 to 57. These characters, together with the petrologic and geochemical characters of plagioclase\|garnet\|orthopyroxenite bearing zircons, indicate that the protolith of plagioclase\|garnet\|orthopyroxenite may be derived mainly from volcanic base surge sedimentary debris in oceanic islands and from clays formed by seafloor weathering. Zircons are simply of pyroclastic debris. The ophiolite formation age of (440±18) Ma and the first\|stage metamorphic age (amphibolite or granulite facies) of (364±5) Ma were obtained with a method of multiple grains in different groups and a method of concordia plot. These ages provide important information on the temporal and spatial occurrence of southern Paleozoic Tianshan Ocean, the subduction rate of the oceanic crust and the formation mechanism of ophiolite of granulite facies.

Historical climate changes in southern Xinjiang

Based on the synthetic researches of multi-index geologic records of Niya section, which are of high resolution in southern margin of the Tarim Basin, together with other geologic records in southern Xinjiang, this paper has reconstructed the history of paleoclimatic changes in this region since about 4.00 ka BP. During the last 4.00 ka, the region of southern Xinjiang has experienced alternations of relative cold-wet and relative warm-dry periods. Three remarkable cold-wet periods (4.00-3.45 ka BP., 2.50-1.90 ka BP., ca.1.40-1.00 ka BP.) and three warm-dry periods (3.45-2.50 ka BP., 1.90-1.40 ka BP., 1.00 ka BP.-present) are identified. It is shown that human activities have an intimate relation with the evolution of paleoclimate in southern Xinjiang.

Research on the Seismotectonic Zones and Seismicity State in the Southern Xinjiang Region

Based on the studies of earthquake activity, tectonic movement, crustal shortening rate, fault activity, local stress field and historical characteristics of strong earthquake activities in Xinjiang, we divide the south part of Xinjiang into 4 seismotectonic zones, namely, the eastern segment of south Tianshan seismic belt, the Kalpin block, the Kashi-Wuqia junction zone, and the west Kunlun Mountains seismic belt. Using earthquake catalogues from Xinjiang since 1900, and on the basis of integrity analysis of earthquake records in different magnitude ranges, the seismicity state of different seismotectonic zones is analyzed quantificationaUy by calculating the mean value of annual strain energy release, annual rate of earthquakes with different lower limits of magnitude, b-value, and the parameter m of accelerating strain release model. The characteristic indexes of seismicity state for each of the seismic tectonic zones are then determined, which provide a quantitative basis for earthquake tendency analysis and judgment.

Surface pollen and modern vegetation in Southern Xinjiang,China

The study of modern pollen,and vegetation can improve the accuracy of paleoenvironmental reconstruction based on fossil pollen data.A total of 188 pollen surface samples were collected from Southern Xinjiang(34°00’–43°00’N,74°00’–94°00’E)in China,with an elevation range of 888–4530 m.Surface pollen and vegetation were studied in the northern region of the Kunlun Mountains and the southern region of the Tianshan Mountains.The results showed that the surface pollen assemblages on the southern slope of the Tianshan Mountains(3530–1124 m)were divided into three pollen zones,namely,montane steppe,montane desert steppe,and montane desert.These zones were dominated by Artemisia,Chenopodiaceae,and Ephedra pollen.The surface pollen assemblages in the eastern Pamir Plateau(4530–1287 m)could be divided into alpine meadow,montane desert steppe,and montane desert zones,which were predominantly characterized by Artemisia,Chenopodiaceae,and Asteraceae pollen.However,the Southern Tarim Basin(3548–888 m)comprised montane desert steppe and montane desert zones,which was dominated by Artemisia and Chenopodiaceae pollen.The geographic distribution of the surface pollen sites obtained using ArcGIS,the R-value,and Pearson correlation analyses indicated that the over-represented Picea and Pinus pollen were of external origin and were transported by wind,water(rivers),and ice(glacier movement).Over-representation of Ephedra and Nitraria pollen was mainly distributed in the montane desert and desert steppe zones,respectively.Pollen from Chenopodiaceae and Artemisia were over-represented and broadly distributed across Southern Xinjiang.Juglans pollen was concentrated in areas with walnut trees,strongly indicating the presence of local parent plants.According to the Hybrid Singleparticle Lagrangian Integrated Trajectory model,more Pinus pollen was transported to the Pamir region by external airflows during spring and summer,resulting in its higher surface pollen content.Research elucidating the relationship between modern pollen and vegetation in southern Xinjiang could provide data describing the surface palynological database of Xinjiang for use in large-scale paleoenvironmental reconstructions.

HPV Infection among Uygur Women in a Rural Area of Hetian Prefecture,Xinjiang Uygur Autonomous Region, China

It is not clear how HPV infection is prevalent among Uygur women in Xinjiang Uygur Autonomous Region, China and whether the distribution of HPV infection is related with cervical intraepithelial neoplasia （CIN） incidence among them. A study including 883 Uygur women were conducted from 2006 to 2007 in Hetian Prefecture, Xinjiang Uygur Autonomous Region, China.

How did high temperature extremes in southern Xinjiang,China induce the repaid rise in jujube futures prices in the summer of 2021?

In the summer of 2021,southern Xinjiang,China,experienced a temporary period of high temperature extremes.Because of this weather event,jujube futures prices rose by more than 50%in a short time.To clarify the influence mechanism of these two events,we investigated the current status of jujube farming and collected investors’online comments.We analysed these comments specifically using textual analysis tools,such as co-word networks.Results showed that the concerns of investors about the reduction in jujube production triggered by high temperature extremes were the primary reason for the rapid rise in jujube futures prices.Especially in combination with the cultivation density of jujube and their adaptability to the growing environment,a new understanding can be obtained.That is to say,when a crop is excessively densely cultivated in a region and is highly sensitive to a meteorological variable anomaly at a certain growth stage,a less destructive local extreme weather event could induce severe panic among investors regarding production reduction and thus influence the normal changes in futures price.In response to the impact mechanisms revealed in this study,we proposed policy recommendations,such as strengthening the degree of crop damage disclosure and designing weather futures derivatives,to address similar situations in the future.This study not only fills the gap in the research on the impact paths of high temperature extremes on jujube futures prices but also has a reference value for securing the stability of futures prices of related agricultural products in the future.

不同肥密措施对南疆水稻抗倒伏及干物质生产特性和产量的影响

以新稻36号为材料,在南疆地区进行了以氮肥水平(N)作为主区、栽插密度(D)作为副区的田间裂区试验。结果表明,随施氮量增加,第1节间长度、第2节间长度、弯曲力矩、株高和重心高度显著增加,抗折力则先增后降以N2处理(纯N 240 kg/hm^(2))最高;合理密植能够控制个体发育,降低节间长度、弯曲力矩、株高与重心高度;茎秆倒伏指数由上述因素共同影响,施氮量240 kg/hm^(2)、栽插密度20.83~27.78万丛/hm^(2)的处理抗倒伏性较优。花后干物质积累量对籽粒贡献占比为51.69%~76.14%,是籽粒干物质积累量的主要来源,适当增施氮肥能够提高花后干物质积累量与积累率;过量施肥则会使干物质在花前的积累量增大,多用于营养器官生长,不利于向籽粒转运。适度密植有利于提高花后干物质积累量,D4处理(27.78万丛/hm^(2))较其他处理提高18.06%~30.22%,同时也促进了干物质向籽粒的转运。综合来看,施氮量240 kg/hm^(2)、栽插密度27.78万丛/hm^(2)时能显著改善水稻地上部分干物质的比例及干物质分配,且未发生倒伏,有利于产量提高。

3种抗凝血类杀鼠剂在喀什农区防治害鼠效果及对家禽的安全性评价

为确定适于防治南疆农区鼠害的抗凝血类杀鼠剂,在喀什地区疏勒县采用夹捕法、食饵法、粉迹法评估了杀鼠醚、溴敌隆、溴鼠灵的防治效果,并采用灌胃法给药测试3种杀鼠剂对家鸡Gallus domestiaus和鸽子Columba livia的安全性。结果表明,连续投放毒饵10 d后,与溴敌隆防治区相比,杀鼠醚防治区的阳性粉块和无毒小麦取食量的下降幅度均无显著差异,但无毒小麦取食量下降的农户比例更高;且防治后褐家鼠比例更低,防治期间毒饵消耗量更高。连续单独投放溴敌隆30 d的灭鼠效果可达90.9%,但10 d溴敌隆与20 d溴鼠灵联合防治防效仅为65.9%。灌胃法测试表明,对当地家禽类的毒性从低到高依次为杀鼠醚、溴敌隆和溴鼠灵。因此,建议优选毒性较低的杀鼠醚或溴敌隆用于南疆农区鼠害防治。

1990—2020年南疆阿拉尔垦区棉花物候期的动态变化

物候是气候变化的感应器,能客观反映气候变化对棉花生长周期的影响。为探究气候暖湿化背景下南疆阿拉尔垦区棉花物候期的动态变化,选取1990—2020年南疆阿拉尔垦区棉花物候期数据,运用距平、累积距平、Mann-Kendall非参数检验和滑动t检验等统计学方法,分析南疆阿拉尔垦区棉花物候期动态变化及其突变情况。结果表明,1990—2020年南疆阿拉尔垦区棉花平均播种期、出苗期、现蕾期、开花期、吐絮期和停止生长期分别出现在4月14日、4月29日、6月3日、7月2日、9月17日和10月20日,极差分别为25、23、20、22、44和24 d。1990—2020年垦区棉花播种期和出苗期均呈现极显著提前趋势,表现为“显著提前-稍微提前”的过程变化;开花期和停止生长期均呈现显著提前趋势,表现为“显著提前-稍微提前”的过程变化;吐絮期提前和现蕾期延迟均不显著。1990—2020年垦区棉花现蕾期、开花期和吐絮期阶段性变化特征明显,主要表现在现蕾期的阶段性推迟、吐絮期的阶段性提前、开花期的阶段性推迟与提前上,棉花播种期、出苗期和停止生长期阶段性变化特征不明显。研究结果为更好地评估气候暖湿化背景下垦区棉花生长和科学管理棉田提供理论依据。

南疆膜下滴灌棉花咸淡水轮灌模式研究

[目的]探究不同咸淡水轮灌方式对南疆膜下滴灌棉田水盐、棉花生长及产量的影响,寻求安全、高效、高产的咸淡水轮灌制度。[方法]以棉花为研究对象,在新疆阿拉尔现代农业综合试验站开展大田试验,试验共设置9个咸淡水轮灌处理,探究不同的咸淡水轮灌处理对土壤水盐、棉花生长及产量的影响。[结果]棉花生育期内,随着灌溉微咸水比例的增大,土壤水盐量呈增加趋势,相同微咸水占比条件下,棉花生育前期连续灌溉淡水有利于降低根区土壤盐分水平。微咸水灌溉占比越大对棉花的生长抑制作用越大,花铃期适量的微咸水灌溉有利于促进棉花的生殖生长,但微咸水灌溉频率过高会显著降低棉花的单铃质量。适宜的咸淡水轮灌方式既要保证棉花生育前期的营养生长也要在花铃期适时适量灌溉微咸水以促进棉花生殖生长。[结论]南疆棉花种植中,灌溉微咸水占比不宜过高,建议在苗期、蕾期及花铃前期减少微咸水灌溉频率,在花铃期适当提高微咸水灌溉频率。本研究中最优的咸淡水轮灌处理为“淡淡咸”处理。
