营口县博洛铺公社二道五队,地硬土凉,是碱性土壤,历年棉花产量不高。1980年采用大垄双行和小垄单行地膜覆盖的种植形式,亩产皮棉152斤,每亩地膜成本40.7元。1981年,他们在25亩棉田采用宽窄行的覆膜栽培形式,平均亩产皮棉182斤,地膜成本每亩降低10元。从两年的覆膜栽培形式对比看出,应用宽窄行的形式有如下好处: 1.宽窄行可增加膜面受光率,能充分发挥地膜覆盖的增温效果。宽行封垄较晚,增温时间长,可延迟到7月10日。宽窄行有较宽的行距,给棉株生育创造了较好的通风透光条件,适应地膜棉花植株早发、高大的要求。
Yingkou Boluo shop commune two five teams, to hard soil cool, alkaline soil, the annual output of cotton is not high. In 1980, a large-ridged double-decker row and a small ridge were used for planting in the form of plastic film covering 152 kg of mule per mu and a film cost of 40.7 yuan per mu. In 1981, they used 25 acres of cotton fields with wide and narrow rows of film-mulching cultivation, with an average of 182 kg of lint and a decrease of 10 yuan per mu of mulching film. From the comparison of two years’ film-mulching cultivation form, the application of the form of width and width has the following advantages: 1. Wide and narrow rows can increase the light-receiving rate of the film surface, and can fully exert the warming effect of the mulching film. Wide line closure ridge late, warming a long time, can be delayed until July 10. Wide and narrow rows have a wider line spacing, cotton plants to create a better breeding conditions of light and light to adapt to cotton plants premature hair, tall requirements.
