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%。
The effects of different film mulching methods on soil water content and some agronomic traits of sweet crisp bean were studied using sweet crisp bean variety “Acacia” as test material. The results showed that the total mulching + grass and mulching coverage increased by 15.3% and 23.6%, respectively, compared with that of semi-mulching (CK) soil, and the harvesting duration was increased by 3d and 6d, respectively. % And 46.5% respectively. The dry weight of plants increased by 31.8% and 48.7%, respectively. The effect of increasing yield was the most significant by the way of grass + fullmoon. The yield reached 1583.5kg / 667m2, 19.5% higher than the control.
