摘  要:
为进一步提高遵义市辣椒种植水平,全面评估各栽培处理的效应,以遵椒4号为试材,应用灰色关联度分析法对遵椒4号不同密度双株栽培方式的主要农艺性状进行综合评估。结果表明,遵椒4号种植密度为5 600株/667 m~2时关联度最大(r=0.869 7),产量最高,6 400株/667 m~2产量次之(r=0.810 0);在遵义市播州区及相似生态地区种植遵椒4号,适宜理想双株栽培密度的农艺性状指标是株高78.6 cm、开展度70.8 cm、有效分枝13以上、单株果数36个以上、单株果质量40 g以上,其产量指标即可达到最高值。

摘  要:
In order to further improve hot pepper cultivation in Zunyi City, the grey correlation degree analysis was used in this study to comprehensively evaluate the effects of various planting density treatments on the main agronomic traits of the tested variety Zunjiao 4 in double-plant cultivation. The results showed that a treatment with 84 000 plants per hm~2 of Zunjiao 4 was the highest(r = 0.869 7) in the correlation degree and the yield, and a treatment with 96 000 plants per hm~2 was the second highest(r = 0.810 0) in the yield. The proper indexes of agronomic traits of Zunjiao 4 for the optimal planting density in Bozhou District of Zunyi are 78.6 cm in plant height, 70.8 cm in plant canopy, 13 or more effective branches, 36 or more fruit per plant, and more than 40 g fruit per plant, the yield of which would reach the highest value.
