不同栽植密度对骏枣果实产量和品质的影响

摘要

Three-year-old Junzao (Zizyphus jujube cv.Jun zao) was used to study the effects of the different planting densities on yield and fruit quality changes to find a suitable cropping patterns. The results showed that the yield of different cropping patterns had obvious difference at the maturity of Junzao. Mode 3 (4 995 plant / hm2) had the highest yield performance, reaching 7 528.8 kg / hm2. With the increase of planting density, soluble sugar content increased first and then decreased. VC content did not change significantly. The M3 (4 995 plant / hm2) treatment is better than other modes.%以3年生骏枣（Zizyphus jujube cv.Jun zao)为试验材料，研究不同栽植密度下骏枣产量及果实品质的变化，考察合理的栽植模式。结果表明，在骏枣成熟期，不同栽植模式之间产量差异明显，模式 M3（4995株/ hm2)的产量最高，为7528.8 kg / hm2；随着栽植密度的增加，果实可溶性糖含量先升高后降低，维生素 C 含量变化不明显。综合各项指标，模式 M3处理效果为佳。
