摘要:

为了研究主要栽培因素对油葵产量的影响,确定冀北地区油葵最优栽培方案。本研究采用5因子二次回归正交旋转组合设计,建立播期、密度、氮肥、磷肥和钾肥与油葵产量的效应函数。结果表明,播期、密度、氮肥、磷肥和钾肥随着投入量的增加油葵产量呈先升高后下降趋势,其中播期、播期氮肥互作起着重要的作用。目标产量大于2916.67 kg/hm2时,最优组合为:播期6月30日—7月5日、播种密度54749~55478株/hm2,施用氮肥80.0~85.7 kg/hm2、磷肥44.4~45.0 kg/hm2、钾肥70.3~75.0 kg/hm2

Abstract:

The study aims to explore the effect of main cultivation factors on the yield of oil sunflower, and determine the optimal cultivation scheme of oil sunflower in northern Hebei Province. Five-factor quadratic orthogonal regressive rotation design was applied to establish an effect function of sowing date, density, nitrogen fertilizer, phosphate fertilizer, potash fertilizer and the yield of oil sunflower. The results showed that the yield of oil sunflower increased first and then decreased with the change of sowing date, the increase of planting density and the increasing application rate of nitrogen fertilizer, phosphate fertilizer and potash fertilizer, wherein sowing date and the interaction between sowing date and nitrogen fertilizer played an important role. When the target yield was more than 2916.67 kg/hm2, the optimal cultivation scheme was as follows: the sowing date of June 30th -July 5th, the sowing density of 54749-55478 plants/hm2, the application amount of nitrogen fertilizer of 80.0-85.7 kg/hm2, phosphate fertilizer of 44.4-45.0 kg/hm2 and potash fertilizer of 70.3-75.0 kg/hm2.
