不同培肥营养土对机插秧苗素质及产量的影响

Effect of Nutritive Soil on Seedling Quality and Yield of Mechanical Transplanting Rice

开展了壮秧剂培肥、常规培肥+基质覆盖、常规培肥三种营养土培肥方式对比试验,结果表明:壮秧剂培肥和常规培肥+基质覆盖都可以改善秧苗生长环境,提高出苗率、成秧率,秧苗整齐度和综合素质好,一定程度上减少死苗发生;移栽大田后,秧苗起身快、分蘖多,叶面积指数高,壮秧剂培肥增产效应显著。

The contrast experiment were made on fertility with strong sprout agent, general fertility ＋ matrix covering and general fertility, the result indicated that treatment of fertility with strong sprout agent and general fertility ＋ matrix covering can improve environment of seedling, increase germination rate and seedling rate, make the uniformity of seedling and seedling quality better,it can educe the chance of dead seedling to some extent; after plants were transplanted in a field, the seedlings survival quickly and tillering more, high leaf area index after planting, the treatment of fertility with strong sprout agent has positive effect on yield.
