| 摘 要： | 通过大棚内的甘蔗盆栽试验,研究了不同生育期调亏灌溉条件下甘蔗的耗水规律。结果表明:甘蔗的耗水强度因土壤含水量的不同而不同,各生育期内,土壤含水量大的甘蔗耗水强度就大;甘蔗各生育期的阶段耗水量因生育期的长短而不同,萌芽期的甘蔗耗水量最小,伸长期的耗水量最大。在不考虑降雨因素影响的条件下,研究了甘蔗生长的耗水规律参数。

| Abstract: | Through the experiment of sugarcane pot in canopy,the Water-consuming rule of sugarcane was researched at different growth stages under condition of regulated deficit irrigation.The results showed that water consumption intensity varied with different content of soil moisture and became large with high content of soil moisture in each growth stage.Water consumption was different with the different length of growing period and was the minimal during germination period and became the largest during speedy gro... |
