<跨度样式=“字体大小:14px”> <跨度样式=“Font-Family:Arial,Helvetica,Sans-Serif”>减少种植成本(30%),产量增加(40%)索拉特拉农民采用BT。大规模棉花。由于光泽良好,小睡,纤维表面的蜡,吸收非常低的染料,Saurashtra棉花在国际市场上获得更多利润。高蒸发条件,地下水的稀缺性,降雨条件缺乏缺乏棉花产量。气候变化是将另一种尺寸加入到这种综合性土壤 - 植物植物气氛中的尺寸。不良环境条件加上该地区的水资源稀缺性兴趣农民采用滴灌灌溉用覆盖物。棉花用于缓解气候畸变的影响。作物生长季节期间的实际作物蒸散的测定是声音灌溉调度的极有利。到目前为止,据报道,据报道,对滴灌的可变生物降解覆盖棉花进行可变灌溉制度的滴灌的作物系数。 An experiment was undertaken consecutively for two years (2013-14 and 2014-15) to address this issue. Diurnal and temporal variation of soil moisture with depth was monitored using soil moisture sensors at irrigation regimes 1.0 IW/ETc and 0.8 IW/ETc. The control treatment was taken as drip with no mulch. Adjusted FAO Kc predict higher value than sensor based Kc values at both irrigation regimes. Sensor based Kc-mid values were lower by 12.99% and 30.04% than the adjusted FAO Kc-mid value at 1.0 IW/ETc and 0.8 IW/ETc respectively. Biodegradable plastic mulch reduced Kc-ini value by 72.26% and 66.54% over control at 1.0 IW/ETc and 0.8 IW/ETc respectively. Overestimated adjusted FAO Kc values caused a loss of 78.13mm and 66.54mm of precious water at 1.0 IW/ETc and 0.8 IW/ETc respectively. This study admonishes blind adoption of published FAO Kc curves, for mulch conditions.
