- 摘要:
- 大豆矮秆新品种黑河51是黑龙江省农业科学院黑河分院新选育的品种，为研究其良种良法大垄密高产高效综合配套集成技术模式，特设置保苗45万、55万、65万株·hm-2- 三个密度，进行了田间试验研究、大面积验证及示范展示，测定了各物候期大豆株高、结荚高度、单位面积植株鲜重、单位面积植株干重、叶面积指数、倒伏程度、大豆节数、分枝数、单株荚数、单株粒数、百粒重及产量指标。结果表明：株高、结荚高度、单位面积植株鲜重、单位面积植株干重、叶面积指数均呈现增加趋势；随密度增加，倒伏程度加重，保苗65万株·hm-2--时产生严重倒伏，〖JP3〗导致减产；分枝数、单株荚数、单株粒数、百粒重呈现减少趋势，但单株粒数×密度×百粒重呈增加趋势；在不产生严重倒伏情况下，大垄窄行密植有增产的趋势，高密度比低密度增产效果好，以保苗55万株·hm-2-为最好。〖JP〗黑河51在红色边疆农场保苗株数55万株·hm-2-大面积验证与示范展示，大垄窄行密植和生产上主推的60 cm垄距30万株·hm-2-保苗株数垄三栽培模式对照，产量分别为2 922.16-和2 430.31 kg·hm-2-，增产491.85 kg·hm-2--，增产幅度为20.24%，增收1 385.21元·hm-2-。
- Abstract:
- Heihe 51,a new dwarf soybean variety,is a new variety bred by Heihe Branch of Heilongjiang Academy of Agricultural Sciences.In order to study the integrated technical model of large ridge and dense cultivation with high yield and high efficioncy,three densities of 450 000,550 000,and 650 000 seedlings per hectare were set up.Field experiments and demonstrations were carried out,and the plant height,pod setting height and unit area of soybean in each phenological period were determined also included fresh weight per plant,dry weight per unit area,leaf area index,lodging degree,number of soybean nodes,number of branches,number of pods per plant,number of grains per plant,100-grain weight and yield index.The results showed that plant height,Pod-setting height,fresh weight per unit area,dry weight per unit area and leaf area index all showed an increasing trend; with the increase of density,lodging degree increased,650 000 seedlings per hectare were lodged seriously,resulting in yield reduction; branch number,pod number per plant,grain number per plant and 100-grain weight showed a decreasing trend,but single seedling weight decreased.Grain number×density×100-grain weight showed an increasing trend; without serious lodging,large ridge narrow row close planting had a trend of increasing yield,high density was better than low density,and the best was to preserve 550 000 seedlings per hectare.Heihe 51 had 550 000 seedlings per hectare in red frontier farm for large-scale demonstration and demonstration.The yield of Heihe 51 was 2 922.16 and 2 430.31 kg·hm-2-,respectively,with a yield increase of 491.85 kg·hm-2-,a yield increase of 20.24%,and a benefit increase of 1 385.21 yuan·hm-2-.
