宁县近年来在全县推广复种大豆插入轮作制度,取得较大成功,使全县大豆种植面积仅次小麦面积。夏播复种大豆插入轮作技术的推广,有以下五点重要意义:一是复种大豆插入轮作代替了传统的复种糜子,提高了轮作周期产值。大豆被糜子亩均增产值160元,增2.5倍。二是提高了生态效益。豆茬与糜子茬相比,土壤全氮提高41.1％,速效氮提高8.3％。三是变一季粗粮为细粮,改善了人民膳食结构,提高了生活水平,同时也促进了豆制品加工业的发展。四是这一技术使我县麦茬复种大豆由以前海拔1000米以下的川
In recent years, Ning County promoted the multi-cropping soybean rotation system in the whole county and achieved greater success, making the area of soybean planted only next to wheat. Summer planting sowing soybean crop rotation technology promotion, has the following five important meanings: First, cropping soybean inserted into the rotation instead of the traditional compound broomcorn, improve the cycle output value. Soybeans have been increased production value of mulberry 160 yuan, by 2.5 times. The second is to improve the ecological benefits. Compared with the mung bean stubble stubble, soil total nitrogen increased 41.1%, available nitrogen increased 8.3%. The third is to change one season coarse grains for fine grain, improve the people’s diet, improve living standards, but also to promote the development of soybean processing industry. Fourth, this technology makes my county wheat stubble soybean from previous 1000 meters below sea level
