摘要

为了探讨不同种植方式下冬小麦群体分布对土壤水分蒸散、风蚀与产量的影响

在遮雨棚条件下

采用小区试验

对相同播量下窄行条播、常规条播、撒播3种种植方式的冬小麦麦田土壤水分含量、土壤棵间蒸发、水分利用效率、土壤风蚀量及产量进行比较研究。结果表明

相比较于常规条播

窄行条播和撒播减少了土壤蒸发量和风蚀量

提高了土壤水分利用效率和产量。在全生育期

窄行条播和撒播的土壤蒸发分别比常规条播减少22.26%和23.63%、蒸散量分别比常规条播减少8.06%和9.66%、风蚀量分别减少23.1%和31.1%

水分利用效率则分别比常规条播提高22.75%和26%

产量分别提高13.64%和14.63%。说明在我国西北麦区

窄行条播和撒播有利于提高水资源利用效率

减少风蚀

实现小麦生产高产、高效、节本的目标

是比较适宜的小麦种植方式。

Abstract

Winter wheat is the main crop in northwest regions and planting pattern is one of the most important factor for wheat yield.In this study

in order to investigate the effects of group distribution on evapotranspiration(ET)

wind erosion and yield of wheat under different planting patterns

a field plot test was conducted under experimental condition at agricultural experiment station of Shanxi Agricultural University in 2009.The study mainly focused on the comparisons of soil moisture content(SMC)

soil evapora...
