Optimization Study on Planting Density and Fruit Retention Number for Double-Trellis Training of Small-Fruit Watermelons in Spring Greenhouse Cultivation in the Jizhong Region
摘要
Abstract
In order to clarify the optimal density and fruit retention combination for double-vine training of small-fruited watermelons under spring greenhouse cultivation conditions in the Hebei Central Region,using variety L600 as the test material,four densities(1600,1800,2000,2200 plants·667 m-2)and two fruit retention numbers(1 fruit,2 fruits)were set.The local conventional mode(1600 plants·667 m-2,2 fruits retained)was used as the control(CK).The effects of each treatment on fruit setting ability,yield,quality and economic benefits were determined.The results showed that density and fruit retention number had significant effects on single fruit weight,actual commercial fruit number and commercial fruit rate.When double-vine training was left with 1 fruit,each density could ensure 1 commercial fruit per plant;when 2 fruits were retained,the actual single plant commercial fruit number decreased significantly with the increase of density,from 1.87 to 1.30.The net income of CK was the highest(17063 yuan·667 m-2).The fruit quality of the 1 fruit retention treatment was better:in the 1800-1 fruit treatment,the single fruit weight was 2.21 kg and the sugar content was 12.71 °Brix,suitable for the high-end market.It is recommended that for the mass market,double-vine training with 1600-2 fruits is adopted,and for the high-end market,double-vine training with 1800-1 fruit is adopted.关键词
