摘要

为了探索免耕覆盖技术的保水增产增值效果

2007年在陕西省杨凌区进行了不同播种方法试验。结果表明

免耕覆盖播种比传统耕作1m土层土壤含水率高1.2%;能显著促进玉米幼苗生长和根系发育

孕穗期根系长度26.6m

比对照增加71.6%;每1hm

产量8408kg

增产11.3%

增值1991元。该技术能有效保蓄农田土壤水分

明显增加玉米产量、产值

可在关中灌区及同类地区使用。

Abstract

In order to investigate the effects of no tillage measurements on water holding capacity

grain yield

and production income

an experiment of different tillage ways was conducted in Yangling District

Shaanxi Province in 2007.Results showed that soil moisture was 1.2% higher in no tillage treatment compared with traditional tillage.Moreover

root length of corn in booting stage under no tillage was 26.6 m

71.6% more than that in traditional tillage.Finally

grain yield was 8 408 kg/hm2

which was increased by 11.3%

and production income was increased RMB 1991 yuan more than traditional tillage.The conclusion is that no tillage with straw mulching can efficiently increase soil moisture and evidently increase grain yield and production income.The sowing technology can be used in Guanzhong irrigation area and similar regions.
