从地膜植棉初步实践得到的认识:塑膜覆盖在盐碱较轻的土壤上比起不覆盖的有提高出苗率的作用;而在盐碱较重的土壤上,比不覆盖的反而降低了出苗率。农二师农科所在盐碱较重的土壤上试行膜间播种,既比不覆盖的棉田提高了地温,又获得了较高的出苗率,而且便于回收薄膜,搞得好有可能提高薄膜使用次数。这种播种方式无疑是一项有益的尝试。对土壤含盐量较高的农场、地区不妨试试看。当然,目前对膜间播种的认识还很肤浅,开始试验面积不宜过大。在试验时要加强观察和记载的工作,以便较快地探索出规律来,为地膜植棉增添一项种植方式。
From the initial practice of plastic film to get the recognition: plastic film covered in saline-alkali soil than the non-covered with the role of raising the germination rate; and in saline soil heavier than the non-covered but on the contrary reduced Emergence rate. Nongken Ergai where saline-alkali soil heavier trial of inter-film sowing, both than the non-covered cotton fields increased ground temperature, but also obtained a higher rate of emergence, but also easy to recover the film, and made it possible to improve the use of film frequency. This sowing method is undoubtedly a beneficial attempt. For farms with high soil salinity, try it in the area. Of course, the current understanding of the inter-membrane sowing is still superficial, the test area should not be too large. In the trial to strengthen the observation and records of the work, in order to quickly explore the law to add a film of cotton planting methods.
