近年来,随着保护地蔬菜生产的发展,各地涌现了不少专业村,其社会效益和经济效益都非常显著。为了进一步提高温室利用率,增加种植品种,延长供应期,提高温室栽培的产量和产值,兹介绍几种生产中常用的茬口安排形式。一、一年一茬一些韭菜生产专业村的温室多习惯采用这种形式。11月中下旬,当养好的韭菜根进入休眠后,温室前屋面扣塑料薄膜,新年开始收割第一刀,至5月份收割完毕(共收4刀)。然后,拆除前屋面,变成露地养根子。经5个月的精心管理,到了冬天韭菜休眠后再扣,每亩温室产值4,000～
In recent years, with the development of vegetable production in protected areas, many specialized villages have emerged in various places, and their social and economic benefits are very significant. In order to further improve the utilization of greenhouses, increase the planting varieties, extend the supply period and increase the output and output value of greenhouse cultivation, it is introduced several kinds of crop production arrangements commonly used in the form. First, a year in a row of some leeks in the production of greenhouses and more professional use of this form of greenhouse. In mid-to-late November, when the well-fed leek root enters dormancy, the plastic film on the front of the greenhouse is buckled and the first knife is harvested in the new year, and the harvest is completed in May (a total of 4 knives). Then, remove the front roof, become open-air root. After five months of careful management, to the winter leek dormancy and buckle, the output value per acre greenhouse 4,000 ~
