沙漠地区农业种植技术初探

沙漠地区在没有造林或造林初期防护效益不显著情况下，农业种植受风沙危害比较严重，提高农业种植产量是我们面临的一道难题。本文对中国林科院沙漠林业实验中心井灌区第四实验场风沙环境和三年来的种植情况进行分析，得出农业防风害的措施有以下几个方面：农作物品种的选择；种植时间的调整；以增加起动风速为目的的各项抗风害措施的采用；以减小风沙流强度和目的的阻沙林和固沙工程的建造。这些措施能有效地减小和防止风沙灾害的发

Preliminary Discussion on Agricultural Planting Technology in Desert Area

Under the circumstance of no afforestation and unnotable protective benefits at the initial stage of afforestation in desert area, the harmness of wind drift sand to agricultural planting is seriously dangerous. It is a difficult problem to improve the agricultural planting output. This paper had analyzed wind drift sand environment at the fourth experimental field in the well irrigation region. Some measurements to control wind blast are as follows:selection of varieties of farm crop; adjustment of planting time; adopting measurements for wind damage resistant in order to improve starting wind speed; construction of sand resistant forest and sand fixation project in order to reduce strength of wind drift sand. And these measurements can effectively reduce and prevent the occurrence of wind and sand damage.
