邯郸市在推广立体种植的过程中,涌现出了一批较好的优化种植模式,地芸豆——甘蓝——玉米模式就是其中的一种。1993年邯郸市推广该模式2.5万亩,平均亩产玉米563公斤,地芸豆1260公斤,甘蓝3000公斤,亩产值1694元,实现了粮食亩产和产值双超千,已成为“双千工程”的推荐模式之一。其主要技术要点是: 一、接好茬口:2月上旬播种小拱棚地芸豆,同时在小拱棚中进行甘蓝育苗。4月中旬地芸豆收获后定植甘蓝,并拆除拱棚。6月初收甘蓝,播种夏玉米。 二、科学管理: 1.地芸豆:选用红旗豆,播种前先扣拱棚,播后盖地膜。行距25厘米,穴 Handan City in the promotion of three-dimensional planting process, emerged a number of better optimization of planting patterns, to kidney beans - cabbage - corn model is one of them. In 1993, Handan City promoted 25,000 mu of the model with an average yield of 563 kilograms of corn per mu, 1260 kilograms of kidney bean and 3000 kilograms of cabbage, and an output value of 1694 yuan per mu. This has led to the realization of “double-thousand project” One of the recommended modes. The main technical points are: First, take a good stubble: Early February sowing small arch shed kidney beans, cabbage nursery at the same time in a small shed. In mid-April, kidney beans were planted in cabbage after harvest and the arch shed was removed. Early June received cabbage, sowing summer corn. Second, the scientific management: 1. To kidney beans: use red flag beans, sow the door before sowing, sowing after the film. 25 cm spacing, points
