在澳大利亚塑料大棚容器育苗(PHS)的含义,包括在塑料大棚内将砧木播种于营养盒中培育5个月后,装入塑料袋容器,再移至荫棚内培育的全过程。由于PHS系统的保温条件,柑桔苗木能加速生长,可在二年内育出高质量苗木,当然这也需要精细的管理。 一、塑料大棚性质及其育苗特点 用塑料薄膜覆盖的大棚是密闭式的,无较大气流流动。因此,晴暖天气的通风是非常重要的,需通风时,将两侧薄膜卷起,棚顶具通风设备,可将棚顶的高温气体排出,将温度控制在30～35℃。而荫棚内气流可通过遮阴材料
The meaning of container seedling growing (PHS) in plastic sheds in Australia includes planting the rootstocks in plastic greenhouses for 5 months after they have been planted in nutrition boxes, putting them into plastic bag containers and then moving them to the cultivation of the shade. Because PHS system insulation conditions, citrus seedlings can accelerate the growth of high quality seedlings can be raised within two years, of course, this also requires careful management. First, the nature of plastic greenhouses and nursery characteristics Plastic greenhouse covering the greenhouse is closed, no large air flow. Therefore, sunny and warm weather ventilation is very important, to be ventilated, both sides of the film roll up, roof with ventilation equipment, the roof of the high temperature gas can be discharged, the temperature control at 30 ~ 35 ℃. The shade shed airflow through the shade material
