滴灌条件下水肥调控模式对九三大豆产量影响分析
Analysis on the Influence of Water and Fertilizer Regulation Mode on the Yield of Jiusan Soybean Under Drip Irrigation
摘要
Abstract
In view of the actual situation of the low utilization rate of water resources and fertilizers in Jiu San soybeans,the Jiu San soybeans were taken as the research object,and different levels of irrigation water,nitrogen fertilizer,phos-phate fertilizer and potassium fertilizer were set.The second optimal saturation experimental design was used to establish a regression equation between soybean yield and four factors of water,nitrogen,phosphorus and potassium,and to ana-lyze soybean yield under different water and fertilizer regulation modes under drip irrigation.The research results showed that water,nitrogen,phosphorus and potassium could effectively affect soybean yield,and the order of their effects on yield was:nitrogen>water>potassium>phosphorus.Yield first increased and then decreased with the increase of nitrogen,water,potassium and phosphorus application rates;through the interaction between the two factors,it can be concluded that the changes of soybean yield increased first,and then increased after a certain threshold was exceeded.Yields de-creased accordingly.The effect of nitrogen on yield is greater than that of potassium,phosphorus and water,the effect of water on yield is greater than that of phosphorus and potassium,and the effect of potassium on yield is greater than that of phosphorus.The order of the effect of the interaction of two factors on yield:nitrogen and potassium>nitrogen water>potassium water>nitrogen and phosphorus>phosphorus water>potassium and phosphorus,nitrogen and potassium coupling,nitrogen and phosphorus coupling,nitrogen and water coupling,potassium and water coupling,phosphorus The coupling with water has a promoting effect on the increase of yield,and the coupling with potassium and phosphorus has an inhibitory effect on soybean yield.The research results provide theoretical basis and technical support for the efficient utilization of soybean water and fertilizer resources in Northeast black soil.关键词
