在日光温室冬春茬黄瓜生产中,用云南黑籽南瓜做砧木,嫁接黄瓜,能提高黄瓜抗病、抗低温的能力,可使产量大幅度提高。但在嫁接定植过程中,南瓜根系易受伤或发育不良,因此在栽培管理中,注意采取护根措施,为获得黄瓜丰产打下良好的基础。1.选择疏松基质播种若采用靠接法嫁接黄瓜,可在温室中段做畦,畦埂高出地面10厘米,内铺8厘米厚的过筛细沙,刮平后,用温水浇透,播种南瓜籽,上盖2厘米厚的细沙,并用喷壶浇淋温水,上搭小拱棚保温保湿。当50%种子露
In the winter greenhouse cucumber production in the greenhouse, with Yunnan black seed pumpkin as rootstock, grafted cucumber, cucumber can improve disease resistance, low temperature ability, can significantly improve the yield. However, during the grafting process, the root system of pumpkin is vulnerable or poorly developed. Therefore, in the cultivation and management, pay attention to the measures of protecting the root and lay a good foundation for the cucumber yield. 1. Choose loose matrix seeding If you use the docking method grafted cucumber, mid-section of the greenhouse can be done 畦, 畦 埂 10 cm above the ground, shop 8 cm thick sieved sand, after leveling, drenched with warm water, sowing Pumpkin seeds, covered with 2 cm thick sand, and spray water with watering cans, take a small shed insulation moisturizing. When 50% seed is dew
