1.培育壮秧水稻实行高台育苗后实现了全旱育苗,既满足了秧苗对水肥的要求,又能使土壤气热状况得到合理调节.秧苗根系发育好,抗逆性强,从外部形态上看绿中透黄、茎宽叶厚、分蘖多、插后缓苗快.据调查,高台育秧的根系比过水育秧的根系长2.1厘米、每株多两条根,茎宽多1.1毫米,百株鲜重高10.2克,
1. Cultivation of strong seedling rice after implementation of high-Taiwan nursery seedlings to achieve full drought, seedlings not only meet the requirements of water and fertilizer, but also make the soil gas and heat conditions are reasonably adjusted. Seedling root development, strong resistance, from the external morphology According to the survey, the root system of high-density nursery seedlings is 2.1 centimeters longer than the root system of water-saving seedlings, with more than two roots per plant and 1.1-mm wide stems and more stems, One hundred fresh weight 10.2 grams,
