摘要
以甜脆豆品种"合欢"为试材,研究了不同覆膜方式对土壤含水量及甜脆豆部分农艺性状的影响。结果表明:全膜覆盖+草、全膜覆盖2种方式均较半覆盖(CK)土壤含水量分别增加了15.3%和23.6%,采收期分别延长了3d和6d,植株鲜重分别提高32.5%和46.5%、植株干重分别提高31.8%和48.7%,增产效果以草+全膜覆盖方式最为显著,产量达1 583.5kg/667m2,较对照增产19.5%。
Taking the soft legume peas cultivars‘Hehuan＇as materials,the effect of different plastic film mulching models on the soil moisture and some agronomic traits of soft legume peas were studied.The results showed that the models of full film mulching and straw＋full film mulching were the best.With the models of full film mulching and straw＋full film mulching,the soil moisture were increased 15.3%and 23.6%compared to control,harvest time delayed three and six days,plant fresh weight improved 32.5%and 46.5%,and dry weight 31.8%and 48.7%respectively.The highest yield was 1 583.5kg/667m^2 with the model of straw＋full film mulching,improved 19.5%compared to control.
