江淮丘陵地区大面积引种栽培苹果,开始于五十年代中、后期,目前,苹果栽培面积已在1万亩以上.早期栽植的苹果已成龄,正处于结果盛期.对如何克服当地苹果低产与产量不稳定及如何发挥它们应有的经济效益问题,1981年,我们所、场协作,开展了成龄苹果丰产技术措施的研究,分析主要技术措施对产量形成的影响,通过试验探索今后持续丰产的途径. 供试树21年生,主栽品种是小国光,占试验园苹果树的64.3%,辅栽品种有金冠、元帅、祝光、青香蕉和红玉等.面积为101亩.植株密度:行距6.5米,株距5.5米,每亩18株.
The introduction of large areas of Jianghuai hilly areas apples, began in the mid-and late 1950s, at present, the apple cultivation area has more than 1 mu. Early planting of apples has become mature, is in the peak of the fruit. How to overcome the low yield of local apples And instability in output, and how to exert their due economic benefits, in 1981, we and our institute collaborated to carry out researches on the technical measures for high-yielding mature apples and analyzed the impact of major technical measures on the yield formation. 21 years old for the test trees, the main cultivars are small country light, accounting for 64.3% of the apple garden in the test garden, the auxiliary planting varieties are golden crown, Marshal, wish light, green banana and red jade, etc. The area is 101 acres. Density: 6.5 meters spacing, spacing 5.5 meters, 18 lines per acre.
