一般大棚黄瓜定植时己有6、7片真叶,大部分秧苗出现雌花。因此,为了促发根、缓苗、壮秧、早结瓜,就应根据黄瓜的生物学特性采取相应的栽培措施。 1.浅栽黄瓜根系分布浅,必须浅栽;若栽的过深,则迟迟不能缓苗。栽时按宽窄行开沟浇水,浇水量为沟深的2/3,水渗一半后,把带坨的苗子放入沟内覆少量土再浇水,水渗后再覆土。无论哪种栽培方式,土坨都应高出地面半指,覆土时外露部分也要盖上一层土,
General greenhouse cucumber planting has 6,7 true leaves, most of the seedlings appear female flowers. Therefore, in order to promote root, Huanmiao, Zhuang Yang, early fruiting, cucumber should be based on the biological characteristics of the corresponding cultivation measures. 1. shallow cucumbers shallow root system, must be shallow planted; if planted too deep, the delay can not Huanmiao. When planting a narrow row of ditches by watering, watering the amount of ditch deep 2/3, water seepage half, the Tuotu seedlings into the ditch cover a small amount of soil and watering, water seepage and then cover the soil. No matter what kind of cultivation methods, soil Tuo should be half above the ground, covering the exposed part should be covered with a layer of soil,
