为了确保大棚的安全生产和延长大棚的使用寿命,除了选择适宜的棚架结构和棚型,建立牢固的基础外,在制作与使用时还须注意以下几点: 1.棚距要合理。南北向大棚东西之间的距离不小于1.5~2m,前后排距离不小于3~3.5m,棚距太小易积水,引起棚脚松动,同时,也不利于光照、通风、防风、抗雪及清除大棚间的积雪。
In order to ensure the safe production of greenhouses and extend the service life of greenhouses, in addition to selecting the appropriate scaffolding structure and shed type, to establish a solid foundation, in the production and use must also pay attention to the following points: 1 shed to be reasonable. North-South to the distance between the greenhouse is not less than 1.5 ~ 2m, before and after the row from the distance of not less than 3 ~ 3.5m, the shelf is too small easy to stagnant water, causing shed feet, but also conducive to light, ventilation, wind, snow And clear the snow between the greenhouses.
