Breeding application taking wild peaches as green crabapple tree grafting stocks in Northern China

Abstract

The invention relates to breeding application taking wild peaches as green crabapple tree grafting stocks in the Northern China. According to the breeding application, the local wild peaches are used as the grafting stocks for green crabapple tree seedlings, so that good breeding growth of the green crabapple tree seedlings in the Northern China is realized. According to the application disclosed by the invention, the cultivation adaptability of green crabapple tree grafted seedlings to the Northern China and even the whole north districts with similar site conditions can be improved, and the seedling survival rate is increased from about 35 percent to 90 percent or above, so that supporting conditions are supplied to promotion planting of green crabapple trees in the north of China; introduced green crabapple trees can still show the characteristics of early harvesting and high yield, and the characteristics that the soluble solid content is higher than that of the green crabapple trees in the place of origin, and green crabapples taste better; furthermore, a conventional grafting method for fruit tree seedling breeding is adopted; moreover, stock seeds are easy to collect, and fruit farmers can easily master the grafting method; and the method is easy to popularize.

Description

technical field [0001] The invention belongs to blue In the field of planting technology, especially a kind of mountain peach as green in North China Breeding applications of grafted rootstocks. Background technique [0002] green yes A type in Lee [ Prunus is a subspecies of Chinese Prunus (P. salicina Lindl) in the genus Prunus of the family Rosaceae]. green Originally produced in Fujian Province of my country, it is an excellent local fruit tree. It is favored by people for its excellent fruit quality and has always been one of the important fruits exported locally. From the point of view of the North China fruit market, there is a shortage of fine domestic plum fruit varieties, and there are more bulk fruits and less small "miscellaneous fruits". green Cultivated in North China, the phenological period should be delayed by about one month compared with the original place, and the fruit matures at the end of August and early September, which is a relatively...

Problems solved by technology

[0003] In order to make full use of this precious fruit tree resource in our country, many provinces have all carried out introduction and cultivation, however, green Seedlings are the key to the popularization of planting. According to many years of introduction experiments, it was found that the bluegrass directly introduced from the southern provinces When the seedlings are cultivated in North China, they show poor site adaptability, weak growth of seedlings, and low survival rate. The survival rate of seedlings imported from Anhui is only about 35%, and they cannot grow well.

At present, we have not seen the introduction of bluegrass in northern my country. Reports on successful production cultivation
