为了缩短育苗周期,减少苗田用地,繁育林木良种,加快造林步伐提高造林质量,我们进行了大棚容器育苗试验研究工作。从七八年秋开始立成了两个试验专班(容机设计、容苗培育)由简易试验到成批生产,为逐步实现容器育苗工厂化打基础。现在我们已繁育容器苗六十二个树种十六万个。容苗根系发达,生长健壮,一般八十天左右可用于造林。产量,按大棚实用面积,每平方米六百六十个、年产三批计算,单位面积产量相当于大田育苗的十五倍左
In order to shorten the nursery cycle, reduce seedling land, breed forest seed, speed up afforestation step by step to improve afforestation quality, we carried out the experimental research of nursery container growth. From the autumn of Seventy-eight began to establish two experimental class (capacity machine design, capacity nurturing) from simple test to batch production, in order to gradually achieve the container seedling factory base. Now we have grown 162,000 container seedlings of 162 species. Rong seedlings developed root system, robust growth, generally about 80 days can be used for afforestation. Output, according to the practical area of greenhouses, 600 per square meter, with an annual output of three batches of calculation, the yield per unit area is equivalent to field nursery 15 times
