种植方式和密度互作对露地立架小型西瓜产量和品质影响
Effect of plant arrangement patterns and planting density on yield and fruit quality of vertical-culture mini-watermelon in open field
摘要
Abstract
[Objective]In order to integrate the high yield feature of watermelon product with vertical and densifying technolo-gy,the present study was conducted to develop the optimal planting patterns for mini-watermelon cultivated in the open fields.[Method]Based on vertical supporting device invented previously,the plant cultivar,'Jingying-6'()was employed as the materials to study the effect of different arrangement patterns,(equal row(ER),big and small row(BSR)),and dif-ferent plant densities(37 500 plants·hm -2(D1),33 000 plants·hm-2(D2),and 28 500 plants·hm -2(D3)),on the yield and fruit quality of mini-watermelon using split-plot design.[Results]The results showed that all treatments had significant effects on plant growth,yield and fruit quality of mini-watermelon(P<0.05),and the interaction between arrangement pat-tern and plant density was also significant.The combination of ER and D3 produced the greatest number on the main vine length,stem diameter,leaf number,shoot dry and fresh mass,single fruit weight,setting fruit index and yield per unit. The combinations of BSR with D1 and D2 produced higher growth rate,and more fresh and dry matter accumulation in shoots.Fruit yield per unit in D2 was the highest among all density treatments.The study also showed that,mini-watermel-on in BSR treatment performed stronger vigor and produced more shoot dry matter compared to ER pattern,and its yield was significantly increased.Moreover,its total soluble solid contents in both fruit center and edge were increased,and difference between center and edge of fruit was decreased.Fruit texture was crisp or sandy crisp.[Conclusion]Yield and fruit quality of mini-watermelon were significantly improved by applying the big and small planting pattern with planting den-sity at 33 000 plants·hm -2for vertical and densifying culture in open fields.关键词
