[0057] The preparation of the Chinese herbal medicine infusion is as follows: crush the Chinese herbal medicine (Atragalus membranaceus, Codonopsis pilosula, Coptis chinensis, Sophora flavescens) and add 4 times of water to soak for 48 hours, and then dilute to 1% mass concentration when used.
[0058] The following aspects are further explained below.
[0059] 1. Indoor double bud hooking
[0060] Select layerings with a diameter of 0.6-1.2 cm or virus-free dwarf rootstocks M9-T337, M9, etc. bred by tissue culture. Rootstock seedlings are required to be free from apple green ruffled fruit virus, apple rusty fruit-like virus, apple mosaic virus, apple chlorotic leaf spot virus, apple stem pox virus and apple stem groove virus. The root system of the rootstock has 2-4 bud eyes, and each bud eye has more than 2-3 fibrous roots. Rootstock is cut into length 45cm, preserves in the cold storage of 0 ℃-2 ℃, humidity more than 90%.

The invention discloses a method for cultivating self-rooted rootstock multi-branch big seedlings of annual apples. The method includes the steps of indoor double-bud hooking, nursery garden light increasing and heating, nursery stock growth promoting, horizontal branching promoting, orchard branch pulling labor reducing, growth regulator spraying, and branch growth stop and flower bud formation promoting. Ethephon 75ppm and radix sophorae flavescentis are sprayed once every one week, so that branch growth stop is promoted, and flower bud formation is facilitated. According to the method, a multi-branch self-rooted rootstock big seedling breeding nursery is established, and 2700 self-rooted rootstock big seedlings come out of the nursery every year per mu. The multi-branch self-rooted rootstocks are planted in a newly-built apple orchard, the rootstocks generally bloom in the current year and bear fruits in the second year, and the yield per mu in the fifth year is 4000-5000 kg.
Description
technical field [0001] The invention belongs to the technical field of fruit tree nursery stock cultivation, and relates to a method for cultivating annual apple seedlings with multiple branches from their roots. Background technique [0002] Developed countries in the apple industry generally adopt dwarf self-root stock cultivation. At present, the new orchards in major apple producing countries in the world basically use dwarf self-root stock seedlings. Most countries account for more than 90% of the total area of apples, and 100% of European apple production Adopt dwarf self-root stock close planting cultivation. [0003] In 2016, the total area of apple cultivation in my country was 2.4 million hectares, of which the dwarf dense planting area reached 300,000 hectares, accounting for 12.5%. According to surveys, in recent years new apple orchards have more than 40% close planting with short stock, but most of them are middle stock, and there are very few root stock. ...
