“一边倒”种植方式,是在一定的厢宽上种植一幅表,套栽一行棉花。天门市中岭村从1977年起在1700亩旱地上采取“一边倒”种植方式,粮棉连续10年稳步增产,1987年夏粮平均亩产244公斤,棉花平均亩产140公斤。1987年起在全市推广,1988年冬棉全市预计种植面积在10万亩左右。这种种植方式有以下优越性: 1.扩大了夏粮播种面积 常规种植方式如“两硬行” 即在一定的厢宽上种植一幅麦,厢这套栽两行棉花,夏粮播幅一般占38.8—40%;“三硬行”即在一定的厢宽上种植两幅麦,厢边、厢中套栽三行棉花,夏粮播幅为46.6%;而“一边倒”种植方式一厢中只有一边留预留棉行,且厢宽一般较窄,平均为1米,预留行20厘米(因以后可培蔸,故可留窄),沟宽23.3厘米(高垄窄厢可适当小沟),计43.3厘米,播幅为56.7厘米,即播幅为56.7%,比常规种植方式提
“One-sided” planting methods, is to grow a certain width of the box on a table, planted a line of cotton. Zhongling Village in Tianmen City adopted the “one-sided” planting method on dry land of 1700 mu from 1977. Grain and cotton increased steadily for 10 successive years. In 1987, the average grain yield of summer grain was 244 kg and the average yield of cotton was 140 kg. Since 1987, promotion in the city, 1988 winter cotton city is expected to plant an area of 10 acres or so. This planting methods have the following advantages: 1. To expand the summer planting area of conventional planting methods such as “two hard line” that is, in a certain width of the planted a piece of wheat, carriage of two sets of planted cotton, summer grain sowing generally accounted for 38.8-40%; “three hard line” that is, in a certain amount of width planted two wheat, box edge, boxed three rows of cotton, summer grain sowing was 46.6%; and “one-sided” While leaving cotton line aside, and the car width is generally narrower, an average of 1 m, 20 cm reserved line (because of Pei can be later, it can stay narrow), the groove width of 23.3 cm ), Calculated 43.3 cm, sowing rate of 56.7 cm, or sowing rate of 56.7%, compared with conventional planting methods
