网室是形似温室、钢骨架、玻璃顶棚、四周围网纱的棚,作为一种隔离设施,在蔬菜育种上发挥了很大作用,近年来,用网室育苗、栽培蔬菜,在南方多雨地区已显现出其突出的作用。如武汉等地网室的建造面积和利用正在逐步扩大,其综合利用情况如下:一、繁殖原原种的隔离设施蔬菜上大量的原原种的繁殖都需要进行严格的隔离,网室是一种很好的隔离设施,具有优良的隔离作用。1.集中采粉、集中授粉。利用网室的隔离优势,可将一栋网室隔成若干小区室,进行多个品种的繁殖,能实现集中采粉、集中授粉。克服了地理隔离繁殖一个地方只能繁殖一个
The net room is a greenhouse shaped like a greenhouse, a steel frame, a glass ceiling, and a net shed around it. As an isolation facility, it plays a great role in vegetable breeding. In recent years, Has shown its prominent role. For example, the construction area and utilization of net rooms in Wuhan and other places are gradually expanding. The comprehensive utilization of the net rooms is as follows: I. Isolation facilities for breeding original species The breeding of a large number of original species of vegetables requires strict isolation and the net room is a Very good isolation facilities, with excellent isolation. Concentrate powder, concentrate pollination Utilize the isolation advantage of the net room, you can divide a net room into a number of small room, carry on the multiplication of a plurality of varieties, can realize concentrating the powder, concentrating pollination. Overcome the geographical isolation and breeding a place can only breed one
