不同栽培密度对辣椒生长及产量的影响

Effects of different cultivation densities on the growth and yield of chili peppers

为探索早春大棚栽培辣椒适宜的密度条件,本试验对比分析了该作物在4.05万、4.35万、4.65万和4.95万株/hm^(2)等7个密度条件下的主要农艺性状、产量和经济效益等方面指标。结果表明,该作物在密度较低时,植株个体发育较好,株高、果长、果径和单果重均高于高密度处理;密度条件未影响辣椒果实的外观等性状;随着密度的增加,辣椒的产量及效益均表现为先增加后降低趋势,在密度为4.95万株/hm^(2)时产量及效益最高,分别91125.0 kg/hm^(2)和264937.5元/hm^(2),其次为4.65万和5.25万株/hm^(2)的2个密度处理。适宜的密度条件利于辣椒获得高产,试验结果为辣椒的丰产栽培提供参考。

In order to explore the suitable density conditions for early spring greenhouse cultivation of chili peppers,this experiment compared and analyzed the main agronomic traits,yield,and economic benefits of chili peppers under seven density conditions of 40500,43500,46500,and 49500 plants/hm^(2).The results showed that when the density was low,the individual development of chili peppers plants was better,with higher plant height,fruit length,fruit diameter,and single fruit weight compared to high-density treatments.Density conditions did not affect the appearance and other characteristics of chili fruits.As the density increases,the yield and benefits of chili peppers show a trend of first increasing and then decreasing.At a density of 49500 plants/hm^(2),the yield and benefits were highest,at 91125.0 kg/hm^(2)and 264937.5 yuan/hm^(2),respectively.The second density treatment was 46500 and 52500 plants/hm^(2).Suitable density conditions are conducive to achieving high yields in chili peppers,and the experimental results provide a reference for high-yield cultivation of chili peppers.
