Advance of Rice Drought Resistance,Water Saving Cultivation and Genetic Breeding

The water shortage faced with rice production in China was comprehensively analyzed,and the seasonal as well as spatial and temporal differences were the factors limiting rice production,which would be a severe test for grain production safety.Therefore,solving strategies had been proposed from the following aspects：the improvement of irrigation practices was of significant effect on improving the high efficient utilization of water;the screening of drought resistance cultivars and upland rice cultivation could also greatly improve the ability of drought resistance;the combination of traditional breeding techniques with modern transgenic technology as well as the QTL analysis had made considerable progress on improving the soil moisture productive potential of rice from the perspective of genetics.The development of China＇s rice industry would face greater water scarcity in the future,but the conventional water-saving technologies could only reduce water consume to a certain extent,while the exploration and improvement of the water saving potential of wetland rice to give full play to the biological water-saving function would become the goal of agricultural development in China.

Cotton cultivation technology with Chinese characteristics has driven the 70-year development of cotton production in China

Since the founding of the People’s Republic of China in 1949,significant achievements have been made in cotton production in China.China has maintained its position as the world’s largest cotton producer for 33 years(1983–2015),with average annual increases of 3.5 and 3.9% in the unit yield and total output of cotton,respectively.Cotton production has played an extremely important role in the development of the national economy and the improvement of living standards.Although the cotton planting area has been reduced in recent years,the total output has remained relatively unchanged due to the continuous increase in the unit yield.China’s dominant position in global cotton production is undoubtedly attributed to the progress and development of cotton cultivation technology.Over the past 70 years,China has established a high-yielding and high-efficiency cotton cultivation mode that corresponds to its national conditions,including a large population and a limited land area.Furthermore,cotton cultivation technology is constantly being innovated and developed to keep pace with the times.In this paper,we review the development of cotton production and cultivation in China over the past 70 years,with a particular focus on the innovation and development of cotton cultivation technology with Chinese characteristics.This review is intended to provide guidance for the sustainable development of China’s cotton production in the future and to provide a reference for global cotton production.

Cultivation Technology Regulation of Organic Rice in Yellow Rive Irrigated Area of Ningxia

With the improvement of people＇s standard of living, the demand for or- ganic rice is increasing and its production has also attracted more and more atten- tion of people. Studies have shown that the organic products contain more iron, magnesium, calcium and other trace elements and vitamins C, and lower contents of heavy metals and carcinogenic nitrates. In recent years, organic rice wins the fa- vor of consumers due to its pure natural and pollution-free advantages. Based on the planting area selection, organic rice variety screening, fertilization, control of dis- eases and insect pests and harvesting, this article specifically discussed the cultiva- tion techniques of organic rice and developed the cultivation technology regulation of organic rice in Yellow Rive irrigated area of Ningxia, in order to lay the foundation for speeding up the development of organic rice industry and establishing highly standardized and normalized organic rice production base, thereby promoting the standardization of organic rice production.

Minimizing sperm oxidative stress using nanotechnology for breeding programs in rams

Background Artificial insemination(AI)is a routine breeding technology in animal reproduction.Nevertheless,the temperature-sensitive nature and short fertile lifespan of ram sperm samples hamper its use in AI.In this sense,nanotechnology is an interesting tool to improve sperm protection due to the development of nanomaterials for AI,which could be used as delivery vehicles.In this work,we explored the feasibility of vitamin E nanoemulsion(NE)for improving sperm quality during transport.Results With the aim of evaluating this proposal,ejaculates of 7 mature rams of Manchega breed were collected by artificial vagina and extended to 60×10^(6)spz/mL in AndromedR.Samples containing control and NE(12 mmol/L)with and without exogenous oxidative stress(100μmol/L Fe2+/ascorbate)were stored at 22 and 15℃and motility(CASA),viability(YO-PRO/PI),acrosomal integrity(PNA-FITC/PI),mitochondrial membrane potential(Mitotracker Deep Red 633),lipoperoxidation(C11 BODIPY 581/591),intracellular reactive oxygen species(ROS)production and DNA status(SCSAR)monitored during 96 h.Our results show that NE could be used to maintain ram spermatozoa during transport at 15 and 22℃for up to 96 h,with no appreciable loss of kinematic and physiological characteristics of freshly collected samples.Conclusions The storage of ram spermatozoa in liquid form for 2-5 d with vitamin E nanoemulsions may lead more flexibility to breeders in AI programs.In view of the potential and high versatility of these nanodevices,further studies are being carried out to assess the proposed sperm preservation medium on fertility after artificial insemination.
