玉米“二比空”通透栽培技术就是通过改变传统农机整地起垄方式、改变种植模式,把垄距65cm小垄种2垄空1垄,增加玉米种植株数,充分发挥边行效益,增强光合效率,提高玉米产量。2014年黑龙江省汤原县多点试验、示范面积2000hm2,产量可达15t/hm2。以下本文对玉米“二比空”通透栽培技术做如下简要论述,以供参考。
Corn “two more than empty ” transparent cultivation technique is by changing the traditional farmland preparation ridge way, change the planting mode, the ridge distance of 65cm small ridge ridge ridge 2 ridge 1, increase the number of corn planted, give full play to the benefits of the side line, Enhance photosynthetic efficiency and increase corn yield. 2014 in Tangyuan County, Heilongjiang Province, more tests, demonstration area of 2000hm2, the output up to 15t / hm2. The following article on corn “two empty ” transparent cultivation techniques to do the following brief discussion, for reference.
