Grafting technique of pearl oil apricot

Abstract

The invention discloses a grafting technique of pearl oil apricot. When grafting is performed in winter, wild apricot is used as rootstock to graft apricot biloba then pearl oil apricot in a greenhouse. The technique utilizes the greenhouse to graft in winter, the original natural law that seedling grafting can only be performed in spring and summer is broken, the grafting period of seedlings is advanced, cultivation time of products can be advanced by 3 months, and the products can come into the market in anti-seasons; containers are used for raising seedlings in the greenhouse, management iscentralized and fine, the seedling controllability is high, and nursery time of the seedlings can be greatly shortened, and the survival rate of the seedlings also can be improved when the seedlingsare removed from bare ground and planted; meanwhile, due to the utilization of the wild apricot for grafting apricot biloba then pearl oil apricot, not only is cold resistance of pearl oil apricot improved, but also pearl oil apricot fruits are big and have good looking, high yield and high kernel yield, and the economic value of the pearl oil apricot is more than one time of the wild apricot. Moreover, the forestry production can be arranged according to farming season, the labor peak is avoided, the labor contradiction of agriculture and forestry is relieved, and the economic benefits are increased.

Description

technical field [0001] The invention relates to the field of forestry, in particular to a technique for grafting pearl oil apricot. Background technique [0002] Pearl oil apricot is a new variety of seed plant variation, mainly produced in Shandong area. The seedlings grafted or planted in spring form flower buds in the same year, and can bear fruit in the next year. The fruit is oval, the fruit shape is correct, the top of the fruit is slightly flat, the suture line is obvious, and the two halves are symmetrical. The average single fruit weight is 26.3g, and the maximum single fruit weight is 38g. The young fruit is green, yellow when ripe, translucent, the fruit surface is smooth and oily, hence the name oil apricot. The pulp is orange-yellow, tough and hard, with a strong, sweet taste, aroma and high quality. The soluble solid content is 23.5%. After the fruit is ripe, it will not soften after being stored at room temperature for a week, and it will not fall off when...

Problems solved by technology

In order to improve the cold resistance of the pearl oil apricot, the grafting technique using apricot as a rootstock is often used when planting in the above-mentioned areas. It is only carried out in spring and summer. At present, there is no record that grafting can be carried out in winter. It often results in that when a large area of ​​pearl oil apricot needs to be planted in spring and summer, the number of seedlings is insufficient to meet the production needs, and the survival rate of grafting is low.

And because spring and summer are busy seasons for farming, grafting in spring and summer is likely to cause labor conflicts and increase labor costs
