- 摘要:
- 为促进礼品西瓜产业发展,以礼品西瓜品种“小佳铃”为试验材料,在塑料大棚内进行吊蔓栽培裂区试验,以整枝方式(单蔓整枝、双蔓整枝、三蔓整枝)为主区,5个密度(1 600,1 800,2 200,2 800,3 700株?667 m-2)为裂区,对不同整枝方式与密度下礼品西瓜农艺性状、产量因素、品质进行分析比较。结果表明:不同的整枝方式与密度对礼品西瓜的产量与品质都有显著影响,同一整枝方式下,随着密度的增加,单果重降低,品质下降,产量先增后减。综合表现为双蔓整枝、密度2 200株? 667 m-2的产量最高,产量达到3 987.54 kg? 667 m-2;其次是单蔓整枝、密度2 200株?667 m-2的产量达到3 895.28 kg?667 m-2 ,二者可溶性固形物含量无显著差异。
- Abstract:
- In order to promote the development of min-watermelon industry,“Xiaojialing” was selected in text of split-plot design,in which pruning methods (keep one vine,keep two vines,keep three vines)were taken as main-plot and planting densities as(1 600,1 800,2 200,2 800,3 700 plants?667 m-2) sub-plot.The results showed that different pruning methods and densities had significant effects on the yield and quality of min-watermelon.In same pruning method,with the increase of density,the weight of single fruit decreased,the quality decreased,and the yield increased first and then reduced.Keep two vines 2 200 plants?667 m-2 treatment was the best,yield was 3 987.54 kg?667 m-2.The second best of yield and better quality was keep single-vine 2200 plants?667 m-2,yield was 3 895.28 kg?667 m-2.The soluble solids content of the two treatment had no significant difference.
