摘要
以"一品天下208"甜瓜为试验品种,在日光温室内进行了灌溉试验研究,采用20蒸发皿的日水面蒸发量为灌溉水量控制指标,设置了不同蒸发量系数(0.45;0.6;0.75;0.9)的供水处理,研究表明:不同水分处理条件下,单株产量T3最大,T1最小;不同处理各阶段灌水量及耗水量,采用T3处理适宜植株生长需求;T3处理水分利用效率最优,达到34.59 kg/m3;甜瓜产量与灌水量及耗水量均呈现明显的二次函数关系;T3处理产量高,品质好,有利于改善果实品质。
This study was conducted to seek the effects of different irrigation amount on yield,water use efficiency and quality of muskmelon.The irrigation experimental study was conducted with the ＇Yipin Tian Xia208＇ muskmelon as experimental materials in greenhouse and the water surface evaporation measured by a standard 0.2 m diameter pan was used for irrigation control.Different water-supply treatments with different evaporation coefficient,namely 0.45,0.60,0.75 and 0.90,were set up in this experiment.The results showed that the T3 had the largest yield per plant and the T1 had the minimum;the irrigation capacity and water consumption of the T3 treatment was suitable for plant growth in different processing stages;the T3 treatment had the optimal water use efficiency,which is up to 34.59 kg/m3;the relation between yield and irrigation water,water consumption volume showed significant quadratic function relationship;the T3 treatment had high yields,good quality and was propitious to improve fruit quality.
