种肥用量对免耕半固态直播稻产量构成与稻米品质的影响
Effects of Seed Fertilization Level on the Yield and Grain Quality of Semisolid State Direct Seeding Rice with No-tillage
摘要
Abstract
A field experiment was conducted to study the effects of seed fertilization level on the yield and grain quality of semisolid state direct seeding rice with no-tillage,and screen out the optimum seed fertilizer level.Data showed that the yield of semisolid state direct seeding rice with no-tillage was decreased when the application of compound fertilizer and nitrogen fertilizer was reduced at suitable amount.Compared with traditional tillage direct seeding,the yield of semisolid state direct seeding rice with no-tillage showed a trend of increased at the first and decreased afterward as the increasing of seed fertilizer amount.The best effect was observed when the seed fertilizer at the rate of 62.53 kg/hm2,with matrix compound fertilizer and slime ratio of 0.8∶ 100.Semisolid state direct seeding with no-tillage was beneficial to the increase of rice yield,but it will reduce the milled rice rate to a certain extent when compared with traditional tillage direct seeding.The rice protein content was reduced when the seed fertilizer was 57.72 kg/hm2,and the matrix compound fertilizer and slime ratio was 0.7∶ 100.There were no significant differences in the indexes of rice quality among different treatments of seed fertilizer application.关键词
