Abstract
Effect of cultivative factors, such as fertilizer, watering, chemical regulate agents and prunning on soybean growth and development, absorption of nutrients (N,P,K), biochemical index, plant types and gross yield were analysed. The results showed that applying fertilizer and watering in seedling stage could promote the growth of middle part organs (leaf, petiole, stem) in middle growing stage. Fertilizer application and watering in flowering stage could increase the growth of upper part organs (leaf, petiole, stem) in middle-late growing stage. Applying nitrogen and phosphorus fertilizers in different stages could greatly enhance the nutrient absorption for corresponding growth centre organs. Using nitrogen fertilizer increased not only the nitrogen content, but also the phosphorus and potassium contents, and showed the tendency that the protein content in seeds were increased with the postponement of appling time. The optimum appling fertilizer time was from initial flowering to 10days after flowering, which could get 15.6%～24.2% yield higher than check, PP333 applied could lead to plant height reduction, leaf smaller, yield increase or decrease. Among 6 chemical regulate agents,Huafu could increase yield by 5.8%.
