Abstract:
In this pot experiment of 2 years, the effects of the water and nitrogen fertilizer on soybeanyields and quality were studied respectively. The results show that the yield of ample water and high nitro-gen treatment is the highest in the four stages , increased by 14. 3%, 24. 3 %,33. 4%,12. 5%than the com-parison respectively. The yield of the most drought and low nitrogen treatment is the lowest , decreased by14. 1 %, 39. 3%, 41. 2%, 33. 1 % respectively. Drought and high nitrogen treatment are beneficial to theprotein compounding not to fat. Compounding compared with the comparison because of different waterand nitrogen treatment. The change range of the soybean protein content is from 1. 5 %which decreased to2. 0%which increased, the fat content is from 0. 8%which decreased to 1. 1%which increased
