玉米是我省主要粮食作物之一和重要的工业原料及饲料。玉米一生需水较多,每亩耗水量约250立方米左右。我省多数年份夏季干旱少雨,给夏玉米生产带来诸多困难。为了提高单位耕地面积粮食产量,经实践,总结出了几点夏玉米节水技术措施。简介如下,供参考。一、灌溉节水技术灌溉节水包括沟灌、畦灌溉、喷灌、滴灌、集雨节水灌溉等几种形式。1、沟灌。在玉米行间开沟深18—22厘米,灌溉水在沟内水平流动,靠重力和毛管作用湿润土
Corn is one of the major grain crops in our province and an important industrial raw material and feed. Water needs more corn per acre, water consumption per acre about 250 cubic meters. Most of the province in summer droughts and summer, summer maize production to bring many difficulties. In order to improve grain yield per unit area of cultivated land, by practice, summed up a few summer corn water-saving technical measures. Introduction is as follows for reference. I. Irrigation water-saving technology Irrigation water-saving, including furrow irrigation, furrow irrigation, sprinkler irrigation, drip irrigation, rainwater harvesting and other forms of collection. 1, furrow irrigation. Ditch between corn rows 18-22 cm deep, irrigation water flows horizontally in the ditch, by gravity and capillary action of wet soil
