Case Analysis of Super-high-yielding Soybean Variety, Zhonghuang 35
The study for high yield of Zhonghuang35,a soybean variety,was carried out in eight locations in Xinjiang from 2006 to 2010. The results showed that the mean yield was 5722. 5 kg·ha-1 ,and the yield record was 6088. 35 kg·ha-1 in 2010. The reasons for high yield of Zhonghuang35 are that it is a semi-determinate type variety with tenacious stem, moderate leaf area,even and tense distributed pods on the plant. In addition,the illumination is sufficient in Xinjiang where the temperature difference between day and night is obvious,which is beneficial for the photosynthetic accumulation. The proper cultivation measures such as the suitable density of 300 thousand plants per hectare,and drip irrigating along with fertilizing at appropriate time according to water and fertilizer requirement law of soybean population also contributed to the high yield of Zhong-huang35.
