豇豆在我县栽培十分普遍,但大部分集中于6月份后才上市,因此产品价格低,经济效益差。而4、5月份价格高却极少产品上市,为此陈东乡从2000年冬开始进行早春豇豆的栽培试验,利用小拱棚加地膜覆盖技术,把播种时间提前到1月上中旬,上市时间提前到4月下旬。2001年冬栽培面积达刭30亩,比露地栽培提早1个月上市,产量增加30％—40％,平均亩产达2350公斤,亩纯收入达1768元,取得较好的经济效益。现将其栽培技术介绍如下:
Cowpea cultivation in our county is very common, but most concentrated in the market after June, so the product price is low, poor economic efficiency. In April and May, high prices but very few products to market, this Chen Dongxiang from the winter of 2000 began early spring cowpea cultivation trials, the use of small arch plus plastic film covering technology, the sowing time ahead of January to mid January, time to market early To late April. In the winter of 2001, the cultivation area reached 30 mu, which was listed one month earlier than the open field cultivation. The output increased by 30% -40%. The average mu yield reached 2,350 kilograms. The net income per mu reached 1,768 yuan, achieving good economic benefits. Now its cultivation techniques are as follows:
