影响矮砧金红苹果盛果期果实外观质量因子的研究

A Study of ‘Five Kinds of Resistances’ Cultivated Skill for Vegetable Using Water-Cultivation Method in the Slack Seasons of Summer and Autumn

摘要:

矮砧金红苹果盛果期果实外观质量与栽培密度、枝果比、单株产量密切相关。随着栽培密度的增加，果实着色下降，果面水锈发生严重且树龄提早；单果重与植果比、单株产量负相关。利用GM256中间砧生产优质金红苹果，永久性植株合理株距不应小于2.0m，枝果比应大于2.5：1。在2m×3.5m密度下，果实丰产、稳产、优质的适宜负荷量为15.5～18.0kg/株。

Abstract:

It has a good ability to regulate and control environmet for the water cultivated system consisting of assembly bed with good heat insulation property, covering sunshading net and sheltershed with preventive aging plastic film. By using the system in cultivate vegetable to prevent the hightemperature, storm, strong illumination, typhoon and waterlogging. We can gain a good yield, good quality, rapid growth of the vegetable and remarkable economic benefit.
