摘要
以高油酸花生(Arachis hypogaea L.)品种中花215、中花28和中花34为试验材料,采用小区试验对比的方法研究不同播种方式(单粒播种、双粒播种、单双粒间播)对高油酸花生生长性状及产量的影响.结果表明,不同播种方式对高油酸花生生长性状及产量均产生一定影响,单粒播种更有利于花生单株生长发育,相比其他两种播种方式,能显著提高叶片SPAD值、单株结果数、单株生产力和干果产量;单双粒间播和双粒播种的干果产量无显著差异;3个高油酸品种单粒播种的经济效益最高,单双粒间播次之,双粒播种最低;相同播种方式下,中花215的产量和经济效益最高,中花34次之,中花28最低.
Abstract
The effects of different sowing methods(single-seed sowing,double-seed sowing,single and double grain interseeding)on growth traits and yield were studied by using the method of plot test comparison among the peanut(Arachis hypogaea L.)varieties(Zhonghua 215,Zhonghua 28,and Zhonghua 34)with high oleic acid content.The results demonstrated that different sowing methods had a certain effect on the growth traits and yield of the peanut with high oleic acid content.Single-seed sowing was more conducive to the growth and development of the peanut.Compared with the other two sowing methods,it could significantly increase the SPAD value of leaves,the number of pods per plant,the productivity per plant and the yield of dry pods.There was no significant difference in the yield of dried fruit between single and double grain interseeding and double-seed sowing.The economic benefit of single seed sowing was the highest,followed by single and double grain interseeding and double-seed sowing.Under the same sowing method,the yields and economic benefits of Zhonghua 215 were the highest,followed by Zhonghua 34,and Zhonghua 28 was the lowest.
