一、带土小苗移栽的由来与发展日本水稻的育秧方式,自四十年代以来有相当大的变化。虽然在同一时期往往有多种育秧方式并存,不易按单一秧田类型划分时期,但就育秧方式的演变过程看,一般是依水秧田——半旱秧田——保温半旱秧田——保温旱秧田——室内育苗的顺序而发展的。后三种育秧方式,被认为对于实现水稻早栽、避寒、早熟以及确保稳产丰产起着一定作用。其中室内育苗是较新、较晚发展起来的育秧方式,也是带土小苗移栽发展起来的基础。据报导,室内育苗是在1954年由日本长野县农业试验场开始的。1957年首先出现所谓“‘电研’室内育苗器”,1960年后则发展为多种大型的育苗
First, the origin and development of soil seedlings transplanting Rice cultivation in Japan, there have been considerable changes since the forties. Although there are many ways of growing seedlings coexisting in the same period, it is not easy to divide the single seedling types into different periods. However, in terms of the evolution process of seedling growing methods, it is generally based on water seedling - semi-dry seedling - semi-dry seedling insulation - - Indoor nursery order and development. The latter three methods of raising seedlings are believed to play a role in achieving early rice planting, cold shelter, early maturity and ensuring a stable and high yield. Among them, indoor nursery is a newer and later developed nursery method, which is also the basis for the development of transplanting seedlings with soil. It is reported that indoor seedling was started in 1954 by Nagano Prefecture Agricultural Experiment Station in Japan. In 1957, the so-called “Electro-Research” indoor nursery equipment appeared first, and after 1960, it developed into many large nurseries
