The results showed that during tuber development the changes in concentrations of total starch, amylopectin and amylose were ＂S＂ shaped curve un-der different nitrogen fertilizer treatments, in line with the Logistic equation Y=K/（1＋ae-bT）, but both starch accumulation intensity and the time reaching to maximum ac-cumulation intensity were not exactly the same in different nitrogen fertilizer levels so is it with different varieties. Furthermore, high starch concentration variety ‘XS-1’, the largest accumulation of strength of amylase was the lower in the middle fertil-ization and higher in low and high fertilization treatments. The contents of amy-lopectin, total starch were first increasing and then dropping with the amount of ni-trogen increasing. To low starch concentration variety ‘XS-2’, with nitrogen fertilizer content increase, the largest accumulation of strength was reducing in amylose, but was rising in amylopectin and changed from rising to fal ing in total starch. The time reaching to maximum accumulation strength in amylose and total starch changed from increasing to decreasing and amylopectin kept declining.展开更多

The result showed that autumn and winter landscape plants in Kuitun City were primarily evergreen coniferous and deciduous trees outstanding for their shapes and colors, and that landscape was created through different types of plant disposition. Especially colors of trunks, barks, leaves, winter buds and fruits' colors provided favorable conditions for appreciating plants in autumn and winter. Finally, suggestions were proposed according to the investigation and analysis of autumn and winter ornamental plants in Kuitun City, so as to provide reference for future construction and development of landscape plants.展开更多

The resuIts showed that the benefit increasing effect was significant because autumn potato/rapeseed intercropping patterns couId galn more one season potato in rice-rapeseed rotation area. The average yield of autumn potato and rapeseed in two test points were 13 567.35 and 2 663.25 kg/hm2 respectiveIy, and the total out-put value and net income reached to 38 773.05 yuan/hm2 and 15 772.5 yuan/hm2 respectiveIy, and cash income attalned 38 773.05 yuan/hm2, and net income reached 23 000.55 yuan/hm2, and the increased income was 17 221.8 yuan/hm2 and it increased by 310.3% comparing with rapeseed of soIe cropping. Therefore, the autumn potato/rapeseed intercropping in rice field is a new efficient cuItivation technique with very significant ecoIogical and economic benefit.展开更多

The count- able and measurable properties, fatness, mature coefficient, relative fecundity, as well as the fertilized and the hatching rates were measured. The results showed that there was no significant difference between the fatness of the two species （P〉0.05） and between the fatness of male and female Paramisgumus dabryanus （P〉0.05）, while significant difference existed between male and female Misgurnus anguillicauda- tus （0.01〈P〈0.05）; the mature coefficients of Paramisgurnus dabryanus and Misgurnus anguillicaudatus were of 6.56% and 11.36%, respectively; the relative fecundities of Paramisgurnus dabryanus and Misgurnus anguillicaudatus were of 115.70 eggs/g and 147.69 eggs/g, respectively; the fertilized rates of Paramisgurnus dabryanus and Mis- gurnus anguillicaudatus were of 90.62% and 97.52%, respectively; and the hatching rates of Paramisgumus dabryanus and Misgurnus anguillicaudatus were of 92.45% and 97.16%, respectively. It was concluded that Misgumus anguillicaudatus was bet- ter than Paramisgurnus dabryanus in breeding performance in autumn.展开更多

[Method] The effects of fulvic acid on growth period, plant morphology, tuber, net photosynthetic rate, chlorophyll content, leaf area index （LAI） and yield of autumn potato were investigated. [Result] The application of fulvic acid prolonged the growth period and increased the plant height, stem diameter, leaf chlorophyll content, LAI, net photosynthetic rate, tuber number per plant, tuber weight per plant and marketable tuber rate of autumn potato, thus increasing the yield. Applying fulvic acid prolonged the growth period of autumn potato by 1-3 d and significantly increased the plant height, net photosynthetic rate, tuber weight per plant and yield of autumn potato （P〈0.05, P〈0.01）. When the application amount of compound fertilizer was reduced by half, applying fulvic acid almost showed the same seedling emergence stage, mature stage, growth period and net photosynthetic rate with applying full amount of compound fertilizer. In particular, no significant difference was found in the yield of autumn potato between fullamount and half-amount compound fertilizer treatment groups in the premise of solid- liquid fulvic acid combined application. [Conclusion] In the premise of unchanged yield, applying fulvic acid can reduce the application of chemical fertilizers and reduce the non-point source pollution of chemical fertilizers.展开更多

Results indicate a strong interannual variability of autumn precipitation over South China and its positive correlation with the autumn western Pacific subtropical high （WPSH）. In the flood years, the WPSH ridge line lies over the south of South China and the strengthened ridge over North Asia triggers cold air to move southward. Furthermore, there exists a significantly anomalous updraft and cyclone with the northward stream strengthened at 850 hPa and a positive anomaly center of meridional moisture transport strengthening the northward warm and humid water transport over South China. These display the reverse feature in drought years. The autumn precipitation interannual variability over South China correlates positively with SST in the western Pacific and North Pacific, whereas a negative correlation occurs in the South Indian Ocean in July. The time of the strongest lag-correlation coefficients between SST and autumn precipitation over South China is about two months, implying that the SST of the three ocean areas in July might be one of the predictors for autumn precipitation interannual variability over South China. Discussion about the linkage among July SSTs in the western Pacific, the autumn WPSH and autumn precipitation over South China suggests that SST anomalies might contribute to autumn precipitation through its close relation to the autumn WPSH.展开更多
