关中地区温室油桃标准化栽培技术研究

Test of Standardized Cultivation Technology of Prunus persica var.nectarina in Glass Room in Guanzhong Area

针对关中地区油桃温室栽培中存在的定植密度不统一、扣棚期把握不准、草苫覆盖时间有误、产量低、品质差等问题,通过一系列标准化栽培技术的试验,提出了温室油桃的标准化栽培技术,这就是定植株行距为150 cm×200 cm;扣棚时期掌握在12月下旬;在温室管理上,晴天草苫揭开、覆盖时间分别为8∶00和16∶00时,阴天分别为10∶00和14∶00;并且在7月上旬至8月上旬用15%多效唑可湿性粉剂200倍稀释液进行全株喷雾2次,以利于油桃的发芽分化。

To solve the problems of controlling plant density, shed period and covering time of grass carpet, low yield and quality of Prunus persica （L.） Batsch. var. nectarina （Ait.） Maxim. cultivated in greenhouse in Guanzhong area, a series of standardized cultivation technology tests were conducted. The results showed that the ideal planting density was 150 cmx200 cm; appropriate shed time was in late December; unveiling and covering time of grass carpet should be 8：00 and 16：00 re- spectively in sunny day, 10：00 and 14：00 in cloudy day and whole plant should be sprayed with 200 dilutions of 15% Pa- clobntrazol WP from early July to early August for 2 times was good for germination and differentiation of nectarine.
