| 摘 要： | 目的]为了探索杂交大豆在不同氮肥因素水平下的生育特性及其高产栽培技术。方法]以杂交大豆杂优豆1号为试验材料,以常规高产大豆蒙91-413为对照,设置5个水平3次重复的氮肥处理,进行杂交大豆生育特性及高产栽培技术研究。结果]终花期时杂优豆1号的分枝数在氮肥水平为90 kg/hm2的C、E处理中分别为7.0和7.4,在氮肥水平为45 kg/hm2的B、D处理中分别为6.4和6.8,在未施氮肥的A处理中仅为6.2;杂优豆1号的单株荚数、单株粒数和单株粒重在氮肥水平90 kg/hm2的C、E处理中分别为104.0个和105.4个、188.0粒和201.0粒2、9.8 g和31.3 g,在氮肥水平45 kg/hm2的B、D处理中分别为95.8和98.8个1、65.7和166.6粒2、6.6和27.0 g,未施肥的A处理中分别为83.9个、141.3粒2、4.8 g。杂优豆1号在C、E和B、D处理中的小区产量分别为4.284、.38和3.813、.82 kg,比A处理增加21.2%、24.1%和7.9%、8.2%。结论]增施氮肥可显著提高杂交大豆单产,充分发挥其增产潜力。

| Abstract: | Objective] The study aimed to explore the development characteristics of hybrid soybean under different nitrogen(N) fertilizer levels and its high-yield cultivation techniques.Method] With hybrid soybean Youza 1 as test material,conventional high-yield soybean Meng 91-413 as CK,N-fertilizer treatment with 5-level and 3-repeation were set up to study the development characteristics and high-yield cultivation techniques of hybrid soybean.Result] The branch number in final flowering of Youza 1 were 7.0 and 7.4 resp.in C and E treatments with N fertilizer level at 90 ?kg/hm2,that were 6.4 and 6.8 resp.in B and D treatments with N fertilizer level at 45 ?kg/hm2 and that was only 6.2 in A treatment with no N fertilizer.The pods number per plant,grains number per plant and grains weight per plant were 104.0 and 105.4,188.0 and 201.0,29.8 g and 31.3 g resp.in C and E treatments with N fertilizer level at 90 ?kg/hm2,that were 95.8 and 98.8,165.7 and 166.6,26.6 and 27.0 g resp.in B and D treatments with N fertilizer level at 45 ?kg/hm2 and that were 83.9,141.3 and 24.8 g resp.in A treatment with no N fertilizer.The plot yields of Youza 1 were 4.28,4.38,3.81 and 3.82 ?kg resp.in C,E,B and D treatment,increasing resp.by 21.2%,24.1%,7.9% and 8.2% comparing with A treatment.Conclusion] N fertilizer increment could increase yield per unit area of hybrid soybean and exert its yield increasing potential fully. |
