无土育秧,是在温室有土育秧的基础上,从1975—1979年试验探索的一种新的育秧方法。五年的试验证明,工厂无土育秧可以大幅度增产,并实现亩产超千斤。 1975年早造试验面积0.56亩,亩产764斤,比温室有土秧亩产710斤增产7.1％,比大田育秧亩产676斤增产12.5％。1976年,试验面积13.5亩,其中1.25亩亩产976斤。1977年试验面积80亩(大部分为温室有土育秧),最高
Soilless seedling cultivation is a new method of seedling raising based on soil fertility seedlings in the greenhouse from 1975-1979. Five years of experiments show that the plant soilless seedling can significantly increase production, and achieve ultra-kg per mu. In 1975 as early as the test area of 0.56 mu, 764 kg per mu, than the greenhouse seedling yield 710 kg mu yield 7.1%, 676 pounds more than the field nursery stock yield 12.5%. In 1976, the test area of 13.5 acres, of which 1.25 acres of mu produce 976 pounds. 1977 test area of 80 acres (mostly greenhouse soil culture seedlings), the highest
