东北西部玉米双垄沟覆膜栽培技术

摘要

Aiming at mulching with double corrugation and cultivating technology, choosing and preparing land, machine type selection, variety choice, earlier planting, rational close planting, balanced fertilization and harvest were introduced. And, machine type selection was introduced emphatically which could reduce agricultural production cost and improve efficiency. The maize yield in three years for this technology was increased 24.7% and the average water use efficiency increased by 0.79 kg/m3, more than that of bare land planting in western area of northeast.%针对玉米双垄沟覆膜栽培技术，从选地与整地、播种机选型、品种选择、适时早播、合理密植、平衡施肥、收获等方面进行介绍，重点对降低农业生产成本、提高效率的播种机选型进行详述，该技术在东北西部地区三年玉米平均单产较裸地增加24.7%，平均水分利用效率提高0.79 kg/m3。
