Abstract

The rapidly growing world population, inadequate accessible freshwater resources, and frequent erratic changes in climate have stressed human being and compelled them to take vital initiatives to prevent water wastage. Water conservation efforts are also intensified in the world's largest water-consuming agriculture sector. The water use efficiency in agronomy has already been enhanced by the adoption of the drip irrigation method, intended to supply water directly to the crop, rather than the land around, thereby minimising water losses up to 70% occurring through evaporation and distribution. Mulching in association with drip irrigation in arid crop agronomy leads to mitigating vigorously water stress in agriculture. Mulch is a layer of natural or synthetic or combination material applied to the surface of the soil as a protective medium between the soil and the atmosphere. Entirely, it is an efficient medium for soil moisture conservation, and soil temperature control, adds nutrients to the soil by preventing leaching and more efficient use of fertilisers, resistor to erosion losses, suppressing the weeding as well as improving the visual look of landscapes. This review paper covers various aspects of mulch, emerging as dynamic water and soil management tool without affecting the value of crops in agriculture.
覆盖对农业生态系统水分管理的影响
世界人口的迅速增长,可获得的淡水资源不足,以及频繁的不稳定的气候变化给人类带来了压力,迫使他们采取至关重要的举措来防止水的浪费。世界上用水量最大的农业部门也加强了节约用水的努力。通过采用滴灌方法,农业用水效率已经得到了提高,这种方法旨在直接向作物供水,而不是向周围的土地供水,从而将蒸发和分配造成的高达70%的水损失降到最低。在干旱作物农学中,覆盖与滴灌相结合可以有效缓解农业用水压力。地膜是覆盖在土壤表面的一层天然或合成或组合材料,作为土壤和大气之间的保护介质。总的来说,它是一种有效的保持土壤水分和控制土壤温度的媒介,通过防止淋溶和更有效地利用肥料来增加土壤养分,抵抗侵蚀损失,抑制杂草以及改善景观的视觉效果。本文综述了地膜作为一种不影响作物价值的动态水土管理工具在农业中的应用。
