晋虞蜜桃栽培技术研究

Study on Cultivation Techniques for Jin-Yu Peach

以晋虞蜜桃为试材,研究了栽植方式、栽培密度、树形、采前落果和树体防冻等因素对树体生长和果实产量品质的影响。结果表明,晋虞蜜桃1m×2m主干形是肥水较差旱地桃园丰产栽培的理想模式,2m×5m二主枝开心形是肥水较好桃园栽培的理想模式;细长枝修剪、合理疏花疏果、配比施肥、喷施天达2116细胞膜稳态剂等措施对晋虞蜜桃采前落果的防治都有显著的作用,而各项技术综合利用时防治效果最好;树体包草、培土和喷施天达2116植物细胞膜稳态剂等措施结合使用,可使桃园受冻株率下降为1%,能明显提高晋虞蜜桃树体抗冻能力。

Effects of planting techniques and planting density, preharvest fruit drop, tree body antifreezing on the growth, fruit products and qulity of Jin-Yu peach were studied in this investigation. The results showed that Jin-Yu peach with 1 m × 2 m central leader training was the ideal model in dry land with poor fertilizer level, but 2 m × 5 m open-centeralized shape of two main branches was the ideal model in water land with high fertilizer level. Long-shoot pruning, rational thinning flower and fruit, combined fertilization and spraying Tianda 2116 all prevented the preharvest fruit drop of Jin-Yu peach remarkably, while comprehensive utilization of various technical was the best. In addition, the studies showed that the frostbite rate of Jin-Yu peach decreased to 1% when tree body was encapsulated with grass, hilled up with earth and sprayed with Tianda 2116.
