‘福佑’佛手瓜不同栽植密度对比试验

Comparison of Different Planting Densities of Chayote‘Fuyou'

为探求佛手瓜新品种‘福佑’最佳定植密度,提高种植效益,试验采用随机区组设计株行距分别为6 m×6 m、4 m×6 m、3 m×6 m、4 m×4 m、3 m×4 m的5个不同定植密度,3次重复,研究其对产量及效益的影响。结果表明：若以生产夏瓜为主可以适度密植,每公顷种600~800株较为适宜,可获得高产高效;若以收获秋瓜为主,应适当减少种植密度;从年产量及年产值来看,以每公顷种植625株左右,株行距4 m×4 m最有利于丰产丰收,获得最大经济效益。

To explore the best planting density for‘Fuyou’, a new species of chayote, and to improve thebenefit of production, an experiment with randomized block design was conducted, including five differentplanting densities： 6 m×6 m, 4 m×6 m, 3 m×6 m, 4 m×4 m, 3 m×4 m and 3 repeats, to research the influence ofplanting density on the output and production benefit of‘Fuyou’. The results showed that： moderately closeplanting density, namely 600-800 plants per hectare, was suitable for producing fruit in summer, which couldachieve high production and economic benefit. For the purpose of autumn harvest, planting density should bereduced appropriately. In view of annual production and annual output value, the maximum economic benefitcould be obtained by a density of around 625 plants per hectare, with spacing of 4 m×4 m, which was the mostsuitable one to high yield and benefit.
