韭菜耐寒性强,是很受人们欢迎的蔬菜。长期以来,人们习惯每年只收3—4次,其他时间进行养根,因而使韭菜在冬季成为短缺产品。如果在栽培技术上来一个革命,在温室或塑料大棚中采用无土栽培(沙培),就可以充分发挥韭菜高产、长寿的特性,实现月月收获、周年生产、连年利用。这是一种能进行大面积集中栽培,实现工厂化生产,简化操作,发展冬季韭菜生产,提高产量、降低成本的新栽培形式。我们采用沙培法生产的韭菜已连续收获培栽41次(每月收割一次),现在仍长势良好,生机旺盛这是一个新的尝试,也是韭菜栽培方式新的突破。我们进行沙培韭菜的具体做法是这样的。 1.选择适宜的砂子砂子是栽培韭菜的基质。可选用水砂或旱砂,砂粒的直径不得小于1毫米,最
Chives cold tolerance is very popular vegetables. For a long time, people are accustomed to receiving only 3-4 times a year, at other times for raising roots, so that leeks in winter to become a shortage of products. If you come to a revolution in cultivation techniques, using soilless cultivation (sand culture) in greenhouses or plastic greenhouses, you can give full play to the characteristics of high yield and longevity of leeks to achieve the harvest on the moon and the moon, the annual production and year after year utilization. This is a new cultivation form that can carry out large-scale intensive cultivation, realize industrialized production, simplify operation, develop leek production in winter, increase output and reduce cost. We use sand culture method of leek production has been cultivated in succession 41 times (once a month harvest), is still growing, vigorous This is a new attempt, but also a new breakthrough leek cultivation methods. This is what we did with Sapele leek. 1. Select the appropriate sand sand is the cultivation of chives matrix. Optional water sand or sand, the sand diameter of not less than 1 mm, the most
