为了达到早果、早丰的栽培目的,对桃树不同整形方式需要选择的苗木类型进行研究。苗木类型有芽苗、1年生苗、2年生苗3种,嫁接品种有‘北京52号’‘瑞红’‘华玉’3个,整形方式有双Y形(每穴定植2株苗)、Y形、主干形3种。对3种苗木类型的不同整形方式2年生树的开花株率、坐果数,1年生树和3年生树的树体生长情况进行调查,结果表明:双Y形选择苗木类型的次序为2年生苗、1年生苗、芽苗;Y形3种苗木类型均可;主干形选择苗木类型的次序为芽苗或1年生苗、2年生苗。
In order to achieve the early fruit, the purpose of the early abundance of cultivation, peach trees need different shaping methods to choose the type of seedlings. There are three types of seedlings: sprouting seedlings, one-year seedlings and two-year-old seedlings. Three grafting varieties are Beijing No. 52, Ruihong and Huayu. Y-shaped, trunk 3 kinds. The results showed that the order of double Y-shape seedling selection was 2-year-old seedlings , 1-year-old seedlings, shoots; Y-shaped three kinds of seedlings can be; trunk selection of seedling types in the order of buds or 1-year-old seedlings, 2-year-old seedlings.
