苏联塔吉克农业研究所精心地采用了一种给棉株心土滴灌的高效技术。这种方法使生长一百公斤棉花的耗水量减少二至三倍以上,同时使产量上升百分之五十至一百。由于水库、灌渠、垄沟泥土的渗透性,因此采用一般的灌溉技术都会或多或少地导致贮水量的损失。假如土壤表层含水量较低,会严重地阻止种子的萌芽。新的灌溉方法将根据植物的生理节律,用多洞眼小孔径的管子对植物根部直接施加有机物和微量化肥,另外把载有低压电流的电线装在管内,以此来加剧微生 The Tajik Agricultural Research Institute of the Soviet Union elaboratedly adopted a highly efficient technique of earth-soil drip irrigation for cotton plants. This method reduces the water consumption of growing one hundred kilograms of cotton two to three times more and at the same time increases the output by 50 to 100 percent. Due to the permeability of reservoirs, irrigation channels and furrows, the use of general irrigation techniques will more or less result in the loss of water storage capacity. If the soil surface water content is low, will seriously prevent the seed germination. The new irrigation method will be based on the plant’s physiological rhythm, the hole with a multi-hole small hole diameter of the plant roots directly applied organic matter and trace fertilizers, in addition to carry a low-voltage current wire installed in the tube, in order to exacerbate the micro
