摘要
设置生物降解膜(BE膜)、聚乙烯膜(PE膜)和无覆膜对照3个处理,研究不同地膜覆盖对水稻生长性状和产量的影响。结果表明:不同覆膜处理水稻株高在幼穗发育期至成熟期均比无覆膜对照高,BE膜和PE膜均具有提高水稻株高的效果;水稻有效穗数表现为BE膜>PE膜>无覆膜对照,BE膜处理和PE膜处理较无覆膜对照显著提高水稻有效穗数(P<0.05),分别提高了20%和13%;PE膜处理和BE膜处理较无覆膜对照显著提高水稻产量(P<0.05),分别提高649.85、1 499.40 kg/hm^(2),增幅分别为12.9%、29.8%;BE膜处理较无覆膜对照节水1 410 m^(3)/hm^(2),节水率达到8%;PE膜处理较无覆膜对照节水795 m^(3)/hm^(2),节水率达到5%。因此,以生物降解膜处理更有利于提高水稻产量和水分利用效率。
The effects of different plastic film mulching on growth characters and yield of rice were studied by setting three treatments:biodegradable film(BE film),polyethylene film(PE film)and no film mulching control.The results showed that the plant height of rice in different film mulching treatments was higher than that in the control from young panicle development stage to maturity stage,and BE film and PE film could improve the plant height of rice.The effective panicle number of rice was BE film>PE film>no film mulching control.BE film treatment and PE film treatment significantly increased the effective panicle number of rice compared with no film mulching control(P<0.05),increased by 20%and 13%respectively.Compared with no film mulching control,the rice yield of PE film treatment and BE film treatment increased significantly by 649.85 kg/hm^(2) and 1499.40 kg/hm^(2)(P<0.05),by 12.9%and 29.8%respectively.Compared with no film mulching control,the water saving rate of BE film treatment was 8%,and that of PE film treatment was 5%.Therefore,the treatment of biodegradable film is more conducive to improving rice yield and water use efficiency.
