不同栽培密度对小冬瓜新品种“黛宝”生长及产量的影响

Effect of Planting Densities on the Growth and Yield of Small Wax Gourd “Daibao”

[目的]研究不同栽培密度对小冬瓜新品种"黛宝"生长、开花和产量的影响。[方法]在小冬瓜果实膨大期,采样测量植株生长指标;在果实成熟期,采样测定植株果实性状和产量。[结果]40~80 cm株距对小冬瓜开花节位无显著影响;40 cm株距时,小冬瓜生长势明显弱于其余处理植株;尽管80 cm株距时植株单瓜重和果实纵径显著高于其他处理,但是,结合定植株数,栽培密度为60 cm时折合产量最高。40~50 cm株距时,植株化瓜现象严重,成瓜数少,产量低。[结论]畦宽1.5 m(含沟30 cm),双行种植,搭人字架栽培的条件下,小冬瓜秋季露地栽培的适宜株距为60 cm。

[ Objective ] To study the effect of different planting densities on the growth, flowering and yield of small wax gourd Daibao.[Method] The plant growth was measured at the fruit enlarging stage, and the fruit characters and yield were determined at the mature stage.[Result] Spacing from 40 to 80 cm in the rows had no significant influence on node order of the first female flower. The plants grew slower in the 40 cm spacing in the rows than the plants in the other plant densities. Although the mean fruit weight and vertical diameter were largest in the 80 cm spacing in the rows, the yield was highest in the 60 cm spacing in the rows considering the number of plants per hectare. Fruit abor-tions were serious in the 40 and 50 cm spacing in the rows, which resulted in less fruit numbers and lowest yield. [ Conclusion] On the condi-tion of 1. 5 m strip width, including 30 cm ditch, double row planting, the best row spacing of small wax gourd is 60 cm in the open field.
