冬雪蜜桃早期丰产栽培技术研究

Study on Snow Peach Cultivation Technique for High Yield in Early Period

冬雪蜜桃具有成熟晚、耐贮藏、效益高的特点,是一种较好的水土保持经济植物.为使这一品种得到推广,自1995年春开始,进行了冬雪蜜桃早期丰产优质栽培技术的研究.经两年多的研究,取得了当年栽植半成苗,当年成花,第二年平均株产5.3kg、最高株产12.3kg的好效果.研究结果表明,改传统的一穴栽植1株为一穴定植3～4株,主枝角度由传统的60°～65°开张到70°～80°,并在生长季节喷生长延缓剂促花,是实现早期丰产的关键.

Snow peach, with the characteristic of late mature, easy hoard and higher benefit, is a kind of good economic plant for soil and water conservation. To spread this plant, since the spring of 1995, the author conducted the study on snow peach cultivation technique for high yield in early period. Two years' practice has made it possible that snow peach is planted and blossomed in the same year, the average yield per tree in the second year reaches 5. 3 kg, the highest 12. 3 kg. The study indicates that changing the traditional measures-planting one tree in a pot with the angle of main branches 60 ~ 70degrees-into planting 3 or 4 trees in one pot with the angle of main branches 70 ~ 80 degrees, improving flower by spraying growth postponing agent in growing season is a key point to realize high yield in early growth period.
