肥密化控对铁豆68号产量的影响

Effects of Different Fertilizer Rates, Planting Density and Plant Growth Regulators on Yield of Soybean Cultivar Tiedou 68

采用正交试验对影响铁豆68号产量的密度、施肥量、叶面喷肥、化控次数4因素进行研究,结果表明,对大豆新品种铁豆68号产量影响的顺序是:施肥量、密度、叶面喷肥、化控次数;铁豆68号最理想的栽培技术模式是密度1.1万株/667m2,施肥量为20 kg/667m2,叶面喷肥1次,化控次数1次。

In order to examine the effects of planting density, fertihzation rates, foliar application and times of plant growth regulator application during the growing period of soybean cuhivar Tiedou 68, the orthogonal experimental design was used to carry out data analysis. The result indicated that the order of cultivation practices on soybean new variety Tiedou 68 was： fertilization rate, planting density, foliar application and times of plant growth regulator application. The ideal cultural pattern of cultivar Tiedou 68 was planting density of 11 000/667m2, fertilization rate of 20 kg/667m2, and one time of foliar and plant growth regulator application.
