摘要

根据渭北旱塬自然经济特点

提出了该区农业持续发展的关键技术和增产新途径-农田高效优化种植模式 (以双元覆盖小麦为主)。通过 4a的试验示范与推广

结果表明:该模式可较对照增产小麦62 .92%;复种黄豆增收 1500～ 2250 kg/ hm

较对照增产 100%。该模式的聚水、保墒、增温和促进有机质矿化、增加土壤养分效应显著

可使土壤水、热环境改善

充分利用水资源

提高用水效率。

Abstract

According to the natural and economic characteristics in the Weibei dry plateau

the key technology and new way to increase production

i. e. high-efficient and optimized cultivation pattern are present . The results of three years experimental demonstration and popularization show that the production of wheat cultivated by the pattern increases by 62. 92% compared w ith CK

it is about 2176 kg /hm2;production of soybean after wheat harvesting (double cropping) increases by 100%

about 1 500～2 250 kg/hm2

both with significant effects.
