目前,日光温室在河北承德地区迅速发展,不仅成为供应京津鲜食菜的生产基地,而且极大地提高了土地利用率,经济效益显著,成为农民发家致富奔小康的支柱产业,脱毒马铃薯微型薯的繁育多在北方高纬度、高海拔地区,夏季气候凉爽,昼夜温差大,光照充足,生育期短,1年只种1季,即春种秋收。利用本地日光温室的优势,对脱毒马铃薯微型薯秋冬茬繁育进行试验,并取得了初步的试验成功。现将日光温室繁育脱毒马铃薯微型薯栽培技术介绍如下。 At present, the greenhouse has developed rapidly in Chengde, Hebei Province. It has not only become a production base for supplying fresh vegetables to Beijing and Tianjin, but also greatly improved the land utilization rate with remarkable economic benefits. It has become a pillar industry for peasants to get rich and get well off. Potato breeding and more in the northern high latitudes and high altitude areas, the summer climate is cool, large temperature difference between day and night, adequate light, short growth period, only 1 year 1 season, that is, the harvest of autumn. Taking advantage of the local solar greenhouse, experiments were carried out on the breeding of autumn and winter cropping of virus-free potato mini-tuber. The preliminary experiment was successful. The solar greenhouse breeding detoxification potato miniature potato cultivation techniques are as follows.
