单粒精播对花生农艺性状及产量品质的影响
Effects of Single-seed Sowing on Agronomic Traits,Yield and Quality of Peanut
摘要
Abstract
In order to further explore the principle of high-yield fine-seeding cultivation techniques,the effects of fine-seeding on the agronomic traits,yield and quality were studied with high-yield and high-quality peanut variety'Xianghua 2008'.The results showed that the seedling emergence rate was decreased as the increasing of density,the main stem height and lateral branch length were the largest at 210 000 plants/hm2,but the number of branches,fruit branches,leaf age and number of pods per plant were decreased as the density increasing.The individual productivity was reduced by single-seeded fine sowing at high-density.The seed yield and quality were the best at density 180 000 plants/hm2,higher than that of conventional production with density 300 000 plants/hm2.Results showed that peanut single-seed sowing reduced seed use rate,increased yield and economic benefit,it is a feasible cultivation technique to realize the high yield and high efficiency of peanut.关键词
