摘要
以邹平细毛山药栽子为材料,采用随机区组试验方法,研究了山药栽子质量、年龄、栽植时期、密度对山药产量的影响。结果表明,选用150-200 g的3 a生的山药栽子,于4月10日左右播种,栽植密度5.25万株/hm^2,叶面喷施0.2%磷酸二氢钾＋1%尿素或0.2%磷酸二氢钾＋0.3%天丰素,整个生育期共喷4次,分别是苗期1次、甩蔓期1次、后期2次,能获得较高产量,增幅达15.03%-18.07%。
With fine hair yam seedlings in Zouping as materials,the random block method was taken in the experiment to study the influence of the quality,age,planting period and density on the yield.The results showed that a higher yield could be obtained when 3-year-old yam seedlings of 150-200 g were selected to plant on April 10,with the planting density of 52500 per ha and foliar spray of 0.2% potassium dihydrogen phosphate＋1% urea or 0.3% Tianfengsu＋0.2% potassium dihydrogen phosphate,yield increasing by 15.03%-18.07%.
