新富1号苹果矮化中间砧与乔砧密植对比试验

Comparative Test of Close Planting between Vigorous Stock and Dwarfing-midolle Rootslock of Apple Xinfu No.1

新富1号矮化中间砧与乔砧密植栽培6年的比较试验结果表明,矮化中间砧密植栽培667 m2枝量较乔砧多29%,中短枝数量较乔砧多175.39%,6年累计产量较乔砧高83.3%,矮化中间砧密植栽培较乔砧早结果1年,单果重、可溶性固形物含量、果实硬度、果实横径、≥75 mm好果率均较乔砧密植有不同程度的提高。果实着色面≥80%果率显著高于乔砧树,全红果率极显著高于乔砧树。矮化中间砧木比乔砧树可提前1年结果,早丰产3年,并利用"高投资、高产量、高品质、高收入"的高度集约化经营。

The experiment was conducted to analyze the results of a 6 - year close planting of Xinfu Nol with 667 m^2 planting area comparison between dwarfing inter- stock and vigorous stock. The result showed that the branch number of dwarfing middle rootstock in close planting was 29% more than that of vigorous stock. Its middle - shoit branch number was 175.39% more than that of vigorous stock. Its accumulated yield was 83.3% higher than that of vigorous stock, The dwarfing- middle rootstock in close planting fruits is one year earlier than vigorous stock. The weight per fruit, content of soluble solids, fruit hardness, the rate of ≥ 75 mm diameter fine fruit were all somewhat higher than those of vigorous stocks in close planting.
