各有关单位: 滴灌技术是一种新型节水灌溉技术。滴灌系统由一系列不同口径的塑料管道组成,灌溉水和溶于水中的化肥从水源被直接输送到作物根部,以点滴或细流形式,均匀地布撒到作物根区的土壤中。该技术具有如下特点:1.适用面广适用于各种可供种植的地形,特别是山区丘陵地带,以管代渠,使山区水利化由难变易;适用于各种林木及除水稻以外的各种作物;适用于各类土壤,尤其在沙土、沙漠上使用更有优势。2.充分利用水资源,更大限度地开发土地资源对于出水量为每小时20m~3左右的小井小
The relevant units: drip irrigation technology is a new type of water-saving irrigation technology. The drip irrigation system consists of a series of plastic pipes of different caliber. The irrigation water and the fertilizer dissolved in water are directly transported from the water source to the crop roots. The drip irrigation system spreads evenly to the soil in the crop root zone by drip or trickle flow. The technology has the following characteristics: 1. Wide range of applications Suitable for a variety of terrain to be planted, especially in mountainous areas, in order to control the canal, making the mountain water conservancy from hard to change easy; suitable for all kinds of trees and except rice All kinds of crops; Suitable for all kinds of soil, especially in sand, desert and more advantages. 2. Make full use of water resources, to develop land resources to a greater extent For the small amount of water per hour 20m ~ 3 small
