不同种植密度对半无土栽培厚皮甜瓜产量及品质的影响

Effects of Different Planting Densities on the Yield and Quality of Muskmelon Under Semi-soilless Cultivation Mode

以美勒三号为试验材料,设置5个密度处理,研究不同种植密度对半无土栽培模式下厚皮甜瓜产量及品质的影响。结果表明:在椰糠半无土栽培模式下,采用单蔓单果整枝方式,不同种植密度下,美勒三号甜瓜果实纵横径变化趋势一致,喷花后前20 d为快速膨瓜期,之后速度减缓直至停止;采收期,种植密度越大,产量越高,单瓜重越低。综合考虑成本、产量及品质等,以26700株/hm^(2)为该种植模式下最合理的栽培密度。

Meile 3 was used as the experimental material,and five density treatments were set up to study the effects of different planting densities on the yield and quality of muskmelon under semi-soilless cultivation mode.The results showed that under the semi-soilless cultivation mode of coconut bran,based on a single vine and single fruit pruning the variation trend of the vertical and horizontal diameter of Meile 3 melon fruit was consistent under different planting densities.The muskmelon expand quickly in first 20 days after spraying flower,and then the speed slowed down until it stopped.During the harvest period,the higher the planting density,the higher the yield,and the lower the weight of a single melon.Comprehensive consideration of cost,yield and quality,26700 plants/hm2 was the most reasonable planting density for this planting mode.
