试验观察研究了秧苗不同入土角度的立苗天数,立苗形态,始蘖节位和比例,结果表明,随着入土角度增加,返青立苗天数减少,秧苗基部弯曲变小,根系分布均匀,始蘖节位愈低,生产上应进一步提高抛秧稻的入土角度。试验还观察了杂交稻与常规稻的相关表现区别。 The results showed that with the increasing of soil depth, the number of days of seedling rejuvenation decreased, the bending of seedling base became smaller and the roots distributed evenly, and the root system became more uniform The lower the tiller node, the production should be further improved throwing rice seedling into the soil point of view. The experiment also observed the hybrid rice and conventional rice related performance differences.
