Hanfu apple nursery stock top grafting method

Abstract

The invention relates to a Hanfu apple nursery stock top grafting method, which comprises the following process steps of: 1, selecting high-quality virus-free pest-free malus baccata borkh stock seedlings as rootstocks for culturing Hanfu apple seedlings and getting ready for grafting Hanfu apple nursery stocks; 2, picking scions from virus-free Hanfu apple trees with the life cycle of 4 to 12 years; 3, grafting the scions to the virus-free Hanfu apple trees; 4, performing bud grafting at the end of July and at the beginning of August; 5, grafting buds of nursery stocks at positions which are 35 to 40 centimeters higher than the ground; 6, removing branches and bounding strips; 7, removing shoots and applying fertilizers before sap flows; 8, ensuring that the height of the seedlings is not more than 1.3 meters, the root length is 20 to 25 centimeters and more than 6 roots are grown; 9, lifting the seedlings before the freezing season; and 10, lifting and grading the nursery stocks at the same time, and storing with sand. The method has the advantages that: the resistance of tree bodies grown from the cultured nursery stocks is greatly increased and the trunks or main branches of the apple trees can be effectively prevented from being frozen and rotted.

Description

Technical field: [0001] The invention relates to a fruit tree cultivation technique, in particular to a high-position grafting method of Hanfu apple seedlings. Background technique: [0002] The new variety of Hanfu apple series is a cold-resistant high-quality large apple with independent intellectual property rights cultivated by Shenyang Agricultural University. It has developed 30 million plants in our province and has been cultivated in 14 cities in the whole province. It is more than 6,000 kg, and the benefit per mu is more than 15,000 yuan. The 30 million Hanfu plants in the province are all cultivated and produced by low-level grafted seedlings. The tree body has poor stress resistance and is not frost-resistant. The tree body is frozen in winter, causing rot on the trunk and branches of the apple tree, which seriously affects the yield and quality of apples. More seriously, the whole tree dies, resulting in a reduction in the production of the whole orchard. Inven...
