Anti-ring-rot apple cultivation method

Abstract

The invention discloses apple cultivation methods, particularly relates to an anti-ring-rot apple cultivation method, and belongs to the technical field of plant cultivation. The anti-ring-rot apple cultivation method is characterized in that biennial Malus hupenensis Rhed is used as the stock, Fuji apple with full branch buds is used as the scion, the Fuji apple scion is grafted at a 65-70cm position through side grafting, and then planting and conventional management are performed to obtain a tall spindle-shaped apple tree in the next year. By the cultivation method, tree vigor can be enhanced, germs can be inhibited, ring rot occurrence rate can be lowered, labor intensity can be lowered, labor efficiency can be increased, pesticide use times can be reduced, diseases and pests can be reduced, the rate of high-quality fruits is increased, early yield, early ripening, early formability and high disease resistance are achieved, and the problems of old orchard continuous cropping renewing and replanting diseases are solved.

Description

technical field [0001] The invention relates to a method for cultivating apples, in particular to a method for cultivating apples against ring spot, which belongs to the technical field of plant cultivation. Background technique [0002] Apple ring disease, also known as rough skin disease and ring rot disease, is one of the three major diseases of apples in my country. According to the manifestation of branch symptoms and differences in pathogenicity, ring spot disease is divided into canker type and wart bark type. Small ulcers, slightly raised verrucous, round. The back is dehydrated and sunken, the edges are cracked and raised, flat and round, with a diameter of about 1 cm, blue-gray. Multiple diseased spots are dense, forming rough trunk branches, with sparse small black spots on the spots. At present, the prevention and control of apple ring disease is a comprehensive control technology combining agricultural control, chemical control and biological control, mainly ...

Problems solved by technology

At present, the prevention and control of apple ring disease is a comprehensive prevention and control technology combining agricultural control, chemical control and biological control.

[0003] Chinese patent, the patent number is 201110091277.6, and the name of the invention is a method for preventing and controlling apple tree branch ring disease. Grafting other excellent apple varieties on the middle stock of Changxiao Guoguang, the red Fuji apples grafted by this method are prone to high-grafting diseases, common diseases such as tiger skin disease of apples, affecting the appearance quality of fruits, and the high-quality fruit rate is reduced

Coupled with the two-knife cultivation method, if the fruit yield is too large, it is easy to cause premature aging of the tree, the tree vigor is weakened, and it becomes a small old tree, which directly affects the economic benefits of the fruit grower.

[0004] Chinese patent, the patent number is 201610710393.4, and the name of the invention is a cultivation method for apple ring spot resistance. This cultivation method is to carry out detoxification treatment on the rootstock, and then grafting after the treatment. Although the detoxification of the rootstock is carried out in this method, due to The operation is cumbersome, the technical requirements are relatively high, and the emergence rate is low. The production cost of seedlings is 8-10 times that of ordinary seedlings, and it is difficult for fruit farmers to bear the cost of garden construction.

If the detoxification link is not well grasped, the seedlings are also prone to diseases, resulting in poor uniformity of the garden

[0005] Apple tree ring disease is a devastating disease of apples, which occurs widely in major apple producing areas across the country, seriously restricting the sustainable development of apple production and industry in my country, and the existing technology is difficult to effectively control the occurrence and spread

In particular, in the 1980s around the Bohai Bay, a large area of ​​red Fuji apples began to be planted. The rootstocks were almost all succulents. In addition, the traditional semicircular pruning pattern of the three main branches at the base resulted in closed canopy and resistance to the tree. The disease is poor, and the ring spot of the branches is very serious. Most of the orchards have begun to renovate
