水稻是人们喜食的细粮作物。但是,由于水源限制,影响了种植面积进一步扩大。因此,1981年我省开展了地膜覆盖旱种水稻的研究,并在全省进行了多点试验、试种。现将有关情况总结如下:一试验在全省41个县、区的重点社队进行。试验项目有:地膜覆盖旱种水稻的品种比较,地膜覆盖条件下的施肥方法和药剂灭草等。试验结果表明,除由于除草药剂使用不当和地下害虫危害等造成部分田块缺苗毁种外,实收的211个点503.3亩中,许多点获得了较好收成。据
Rice is a staple food for people to eat. However, due to water constraints, affected the further expansion of acreage. Therefore, in 1981 our province carried out mulching of dry cultivation of rice, and in the province conducted a number of trials, test species. The relevant situation is summarized as follows: A test in the province’s 41 counties, districts and key teams to carry out. The pilot projects include: comparison of cultivars covering dry-cultivated rice with plastic film, application of fertilizing methods under plastic film mulching and pesticide weeding. The test results showed that many of the 503.3 mu of 211 sites received good yields except for the lack of seeds and seedlings destroyed due to the improper use of herbicides and the hazards of underground pests. according to
