黄土高原冬小麦地膜复盖的农业气象效应的研究

A STUDY ON THE AGROMETEOROLOGICAL EFFECT OF MULCHING WINTER WHEAT BY PLASTIC FILM IN THE AREA OF LOESS PLATEAU

摘要: 地膜复盖是60年代国外农业生产中的一项新技术.它可以有效地改善作物地段的土壤水分和热量状况,有利于作物的生长发育和产量的提高1).在我国逐步推广使用,取得了较好的结果1.本文利用山西省两试验点,在1987-1988年冬小麦生长季进行复膜试验的资料,系统地分析了其农业气象效应.试验结果表明,黄土高原高海拔地区复膜栽培冬小麦是提高其产量的有效措施.

Abstract: Using the experimental data of two points, the effects of soil water and heat of plastic film mulching winter wheat are analyzed systematically. Experimental results prove that the cultivation of plastic filin mulching winter wheat is an effective method for achieving high yield in the area of the high altitude of loess Plateau.
