摘要: 对沿黄稻茬麦田不同耕种方式的生态效应进行了系统研究.结果表明,旋耕条播是沿黄稻茬小麦高产的最佳播种方式,与免耕播种相比,其耕层温度高,土壤容重小,耕层含水量适宜,肥效高而持久,麦田群体和个体发育好,分蘖成穗率高,千粒重及产量最高.

Abstract: The study shows that a cultivation mode of gyrotilling and row-seeding is the optimal mode of seeding for high yield wheat on the field after rice harvesting along Huanghe River banks. Compared with zero-tillage and spread seeding, this cultivation mode makes soilhave a higher temperature, lower bulk density, higher moisture content and persistent high fertilizer efficiency. The population and individuals of wheat are well developed,spike density and tiller number are higher, and thousand-grain weight and yield are thehighest.
