为了减少水稻的生产用工,水稻抛秧栽培已在我国部分稻区进行了试验和推广。目前的抛秧栽培基本上都系从日本引入的塑料秧盘育秧方法,具有易起秧、抛秧的优点,产量与常规栽插持平或略增。但是这种方法所需成本较高,在经济不发达地区农民难以接受,更由于秧龄弹性较小,一般须在四叶期前抛栽,在年三熟制生长季节紧张的广大稻区,其应用便受到一定的限制。为此作者进行了水稻常规育秧
In order to reduce the production and use of rice, rice throwing cultivation has been tested and popularized in some rice areas in China. The current throwing cultivation are basically plastic seedlings from Japan, the introduction of the method of raising seedlings, with easy to seedlings, throwing the advantages of transplanting, yield and conventional transplanting flat or slightly increased. However, the high cost of this method is unacceptable to peasants in underdeveloped areas. In addition, due to the small elasticity of seedling age, it is generally necessary to throw the seedlings before the four-leaf stage. In the vast rice area where the three growing season is intense, Application will be subject to certain restrictions. For this reason, the author conducted conventional rice seedling cultivation
