一、滴灌技术技术概述:滴灌是一种通过安装在毛细管上的滴头,把水一滴滴均匀而缓慢地滴入植物根区附近土壤的局部灌溉技术。它能借助土壤毛细管力的作用,使水分在土壤中渗入和扩散,供植物根系吸收和利用。滴入作物根部附近的水,使作物主要根区的土壤经常保持最优含水状态,且透气性强,利于植物生长。滴灌不仅具有较高的节水增产效果,而且可以结合施肥,提高肥效1倍以上,使水的利用率提高到95%以上,是目前干旱缺水地区最有效的节水灌溉方式。增产增效情况:1.提高劳动生产率和灌溉保证率。管理定额提高2~3倍;水量一定,应用滴灌技术的灌溉面积是常规
I. Drip irrigation technology Overview: Drip irrigation is a technique of local irrigation that drips water evenly and slowly into the soil near the root zone of the plant through a dripper installed in the capillary. It can make use of the capillary force of the soil to make the water penetrate and diffuse in the soil for the root absorption and utilization of the plant. Drops of water near the root of the crop, so that the soil of the main root zone of the crop to maintain the optimal water content, and strong permeability, conducive to plant growth. Drip irrigation not only has a high water yield and yield increase effect, but also can be combined with fertilization to improve fertilizer efficiency more than 1 times, so that water utilization rate increased to 95% or more, is the most effective water-saving irrigation methods in drought and water shortage areas. Increase production efficiency: 1. Increase labor productivity and irrigation guarantee rate. Management quotas increased by 2 to 3 times; certain amount of water, the application of irrigation drip irrigation area is conventional
