我县不少社队地势高,水源缺乏.1981—1982年进行了水稻旱种地膜覆盖栽培试验和大面积示范.不论春播或夏播稻均表现早熟、省水、省肥、灭草、高产.1982年15.3亩麦茬水稻旱种地膜覆盖试验田,平均亩产837.1斤,比不覆盖每亩增产142.6斤.一、地膜覆盖的效果1、提高地温,促进早熟。根据两年试验测定,地膜覆盖的在0—40厘米土层中均有增温效果。1982年5月7日13时在桑庄 Many communes and communes in our county have high terrain and lack of water resources. Experiments and large-scale demonstration experiments were carried out on mulching film mulching in 1981-1982. Both spring and summer seeding showed precocious, water-saving, fertilizing, weed-killing and high yield In 1982, 15.3 mu of dry-land mulching film covering paddy field had an average mu yield of 837.1 kg, an increase of 142.6 kg per acre compared with no coverage. According to the two-year test, the film mulching has the warming effect in 0-40 cm soil layer. May 7, 1982 at 13 o’clock in the Mulberry
