| 摘 要： | 【目的】研究不同密度处理下对花生农艺性状及产量的影响,分析密度与产量的最佳配置。【方法】选取3种花育系列花生品种(花育25号、花育33号和花育36号),设置4个种植密度水平(1.2×105、1.5×105、1.8×105和2.1×105穴/hm2)处理进行列区设计试验,测定不同种植密度下各花生品种的主茎高、侧枝长等主要农艺性状以及产量,筛选最佳种植密度。【结果】密度为1.2×105~1.5×105穴/hm2主茎高要显著大于密度为1.8×105~2.1×105穴/hm2;密度处理为1.5×105穴/hm2的侧枝长比其他处理显著高出1~6.8 cm;单株果数和饱果数均在低密度下最大,随密度的增大而减小;种植密度对总分枝和结果枝影响差异不显著;花育33号在种植密度为1.5×105穴/hm2时产量为最大,为4 555.58 kg/hm2,其次是花育36号、密度为1.8×105穴/hm2处理,第三是花育25号、密度为1.5×105穴/hm2处理。【结论】花育系列花生品种种植密度为1.5×105~1.8×105穴/hm2。

| Abstract: | 【Objective】 To study the effects of different density treatments on agronomic traits and yields of Huayu 25, 33 and 36 series peanut varieties and find out the best configuration of density and yield to promote. 【Methods】 The experiments were carried out to treat 4 planting density levels (1.2×105 holes/hm2, 1.5×105 holes/hm2, 1.8×105 holes/hm2, 2.1×105 holes/hm2) by using split plot design, through the analysis of 3 Huayu series peanut varieties (Huayu 25, 33 and 36). The effects of density on the main agronomic traits, such as main stem height and lateral branch length and yield of each peanut variety under different planting densities were studied in order to select the best planting density. 【Results】 The main stem height in the density range of 1.2×105~1.5×105 holes/hm2 was significantly higher than the density of 1.8×105~2.1×105 holes/hm2; The lateral branches length in the density treatment of 1.5×105 holes/hm2 was significantly higher than other treatments by 1~6.8 cm; The number of pods per plant and well filled pods were the largest under low density, decreasing with the increase of density; Planting density had no significant difference in the effect of total branches and effective branches; Huayu 33 had the highest yield when the planting density was 1.5×105 holes/hm2 which was 4,555.58 kg/hm2, followed by Huayu 36, whose density was 1.8×105 holes/hm2, and the third was Huayu 25, whose density was 1.5×105 holes/hm2 treatment. 【Conclusion】 The planting density of Huayu series peanut varieties is 1.5×105~1.8×105 holes/hm2, which can promote the high yield of peanuts in Bazhou area of Xinjiang. |
