摘要

为了探讨在覆膜基础上不同剂量秸秆还田的保墒增产效果

在辽宁省朝阳市建平县的坡耕地上布设了田间小区试验;对未施入秸秆以及施入400

800

1200和1600kg/hm

共5种不同剂量处理秸秆还田的旱地农田土壤墒情及玉米产量进行了比较分析。结果表明

800kg/hm

处理的保墒效果优于其它各秸秆还田处理

400

800

1 200和1 600kg/hm

这4种不同剂量秸秆还田处理产量分别为5 069.20

5 781.46

5 462.25和5 407.46kg/hm

较对照处理分别增产了18.62%

35.28%

27.81%和26.53%;800kg/hm

处理对玉米生长发育状况的影响优于其它剂量秸秆还田与未施入处理

差异均达极显著水平。

Abstract

In order to investigate on the effects of returning crop residual as mulch in addition to film mulching

field plot experiments were deployed in sloped lands of Jianping County

Chaoyang City

Liaoning Province.Five levels of residual returning(0

400

800

1 200 and 1 600 kg/hm2) were compared in terms of soil moisture retention and maize yield.The results show that the residual returning treatment of 800 kg/hm2 exhibited the best effect on soil moisture retention.The yields of the lands with residual returning of 400

800

1 200 and 1 600 kg/hm2 were 5 069.20

5 781.46

5 462.25 and 5 407.46 kg/hm2

with increases of 18.62%

35.28%

27.81% and 26.53%

respectively

in comparison of the control.The treatment of 800 kg/hm2 also displayed the best influences on maize growth in comparison of the others

as indicated by the statistically significant difference.
