日光温室冬季黄瓜生产在不加温情况下对温室的保温性能和菜农管理水平要求比较高。温室的最低温度不宜低于8℃,最好达到9.5—10℃,不具备这一温度条件的日光温室用于越冬——大茬黄瓜生产时风险比较大,不如改为秋冬、冬春两茬进行生产。下面介绍越冬——大茬黄瓜栽培技术,供参考。一、选择合适品种越冬——大茬黄瓜目前多采用嫁接育苗。接穗品种要求具有耐低温、耐弱光、良好的抗病性。生产上接穗主要使用津春三号等,
Winter greenhouse cucumber production in the greenhouse without warming conditions on the insulation properties and vegetable farmers management level is relatively high. Greenhouse minimum temperature should not be less than 8 ℃, preferably 9.5-10 ℃, do not have the temperature conditions of the greenhouse for winter - big stubble cucumber production risk is relatively large, it is better changed to autumn and winter, winter and spring two stubble in production. The following describes the winter - large cucumber cultivation techniques for reference. First, select the appropriate varieties of winter - large cucumbers now use more grafted nursery. Scion varieties require low temperature, light resistance, good disease resistance. Spike production on the main use of spring three, etc.,
