所谓肥床旱育,就是在深厚、疏松、肥沃的旱地苗床上,采用少浇水的方法培育出矮壮、多蘖、叶色深绿的秧苗。苗床耕作层要求20厘米上下,床土爽水透气性能好,有机质含量达3％以上。因此,通常选择菜园地或肥沃的旱地作苗床。为了增加土壤腐殖质含量,改善团粒结构,增强苗床蓄水保墒性能,必须在冬前施入2000—3000千克/亩的稻麦秸秆和1500 The so-called fat bed dry nursery, is in the deep, loose, fertile dry land on the bed, using less watering methods to breed sturdy, tiller, leaf color dark green seedlings. Seedbed cultivation layer requires 20 cm up and down, bed soil cool water permeability, organic matter content of 3% or more. Therefore, we usually choose vegetable fields or fertile dry land as seedbed. In order to increase soil humus content, improve the pellet structure, and enhance the storage of water and soil moisture preservation performance, we must put 2000-3000 kg / mu of wheat straw and 1500
