1977年开始,我们对水稻工厂有土育秧技术,进行了连续四年的探讨.现将主要结果总结如下.一、床土的选择和处理几年来,我们主要选用旱地沃土和河泥.这两种床土各有利弊.旱地沃土,土粒间空隙大、通气性好,利于根系发育,缺点是采土、粉碎、过筛花工多.河泥则通气性差,立苗期土壤湿度不易掌握,但在河网地区,泥源充足,取泥方便.其次,河泥还具有肥多,菌 Beginning in 1977, we conducted a four-year discussion on soil-based seedling technology in rice factories, and the main results are summarized as follows: 1. Selection and treatment of bed soil In the past few years, we mainly selected dryland fertilizers and river muds. Soil beds have their own advantages and disadvantages of dry land fertile soil, soil particles between the large gap, good ventilation, which is conducive to the development of the root system, the disadvantage is the earth, crushing, screening and more. River mud is poor ventilation, vertical seedling soil moisture is not easy to grasp , But in the river network area, adequate source of mud, mud easy.Secondly, the river mud also has more fat, bacteria
