为了探索早稻稀播少本插后的本田施肥技术,1980至1982年我们在桐乡县华光大队,围绕早稻稀播少本插平稳促进栽培法中的本田施肥技术进行了研究。试验结果表明:在稀播少本插、速效性肥料比例较高的条件下,采用“施足基面肥,重施分蘖肥,看苗巧施穗肥”的“前重”施肥技术(试验中的处理六),容易引起前期猛发,中期群体过大,后期冠层结构变劣,甚至倒伏,病虫害重,影响产量继续增长;采用减少基面肥用量,提高后期用肥比重的“平稳促进”施肥技术(试验中的处理一至五),能够使群体平稳发展,个体生育健壮,肥料效益高,
In order to explore the early rice thinning after the insertion of Honda fertilization technology, from 1980 to 1982 we Tongxiang Huaguang brigade, around the early rice thinning planting smooth promotion of cultivation techniques Honda fertilization technology were studied. The experimental results showed that under the conditions of thin planting and less plugging and higher proportion of quick-acting fertilizer, the “before-heavy” fertilization technique of “applying sufficient base fertilizer, re-applying tillering fertilizer, Of the treatment of six), easily lead to the previous period of fierce, medium-term group is too large, the late canopy structure deterioration, or even lodging, pests and diseases, affecting the production continued to grow; reduce the amount of basal fertilizer to increase the proportion of late use of fertilizer ”smooth promotion" Fertilization techniques (one to five treatments in the trial) enable a steady development of the group, robust childbearing, high fertilizer efficiency,
