Effects of Tillage and Organic Manures Returning to Field on Soil Physical and Chemical Properties and Yield Benefits in Wheat Field
摘要
Abstract
In order to solve the decreasing soil fertility and productivity caused by unreasonable tillage and long-term excessive use of chemical fertilizers,the study of different tillage and organic manures returning to field on soil phys-ical structure,nutrients and wheat yield benefits in deep tillage condition were analyzed in this experiment in Huojia County,Henan Province. There were six treatments about tillage and fertilizing methods in the trial including deep tillage (S),deep tillage with pig manure returning(SF),deep tillage with maize straw returning(SJ),shallow tillage(Q),shal-low tillage with pig manure returning(QF),shallow tillage with maize straw returning(QJ). The results,on one hand,indi-cated that deep tillage with organic manures returning significantly improved soil bulk density and soil porosity,at the same time increased the soil organic matter content,total phosphorus content,and total nitrogen content in 20-100 cm soil layer. In addition,the deep tillage increased the water content in 20-40 cm soil layer. On the other hand,deep tillage with organic manures returning improved wheat yield components and increased wheat yield. Compared with shallow till-age treatment,other treatments increased gain rate by 2. 01％ -39. 98％,and deep tillage with pig manure returning had the highest net income which increased by 3242. 89 yuan per hectare. In a word,deep tillage with organic manure retur-ning,which improved soil physical structure,increased the soil nutrients and crop yield,and caused better economic bene-fits too,would be an effective kind of tillage and fertilizing method for wheat cultivation.关键词
