Problems solved by technology
There are seedlings and grafting propagation in picking tree seedlings. The seedlings bear fruit late and have large variations, which cannot maintain the excellent characteristics of good varieties; conventional grafted seedlings take a long time to cultivate, and it takes one year to cultivate rootstock seedlings and grafted seedlings, and two years to complete the grafted seedlings. cultivation

Embodiment Construction
[0020] The embodiment of the present invention: peach tree green anvil green branch cut grafting method grafting rapid seedling raising method,
[0021] 1) Rootstock harvesting treatment: The seeds used to cultivate rootstocks should be selected from high seedling rate, fast growth, strong resistance, peach or mountain peach seeds, remove the pulp after harvesting, and use 40% methamidophos 1000. Soak for 1 hour in doubling liquid (to prevent fruit-eating flies), and place the waterlogged seeds in a ventilated place to dry until the seed husk is dry;
[0022] 2) Storage: The yellow heart soil is air-dried and thinned, sieved with a sieve with a hole of 1 cm, and sprayed with 40% carbendazim 600 times liquid wet soil for disinfection. The humidity should be kneaded into a ball by hands and dispersed when loosened. The Tibetan seeds should be placed indoors first Put a layer of yellow heart soil on the ground with a thickness of 10cm, and then put the first layer of seeds, each layer...

Abstract
The invention discloses a peach tree green stock-green branch cut grafting rapid seedling growing method. A half-lignification green branch is used as a scion to be grafted to a green stock of a nutrition bag in a cut grafting mode, leaves below the grafted port of the green stock are kept, the grafted port and the scion are bound by plastic strips in a sealed mode, only bud eyes are exposed, as the lignification degree of the green stock and the scion is low, tissue cells are active, the leaves left on the green stock can continue to conduct photosynthesis to manufacture nutrient substances which are supplied to calluses, coalescence of the grafted port is achieved rapidly in a growing period, and therefore the rate of survival of grafting of the lignification scion in a resting period is improved by 20%-30% compared with annual rootstock seedlings . Grafted seedlings can be conveyed out of a flower nursery for garden building from August to September, the seedlings of the nutrition bag do not need pruning, leaf cutting and watering, the root caps are not damaged after the seedlings are planted, a seedling buffering period is avoided after planting, and the leaves fall down and dormancy occurs after the seedlings sprout and slightly mature. The rate of survival of planting of garden building is high, the seedlings grow rapidly, fructification is achieved early, the yield is high, and the peach tree green stock-green branch cut grafting rapid seedling growing method is particularly suitable for garden building of mountainous regions where are dry and have no irrigation conditions in winter and spring.
Description
Technical field [0001] The invention relates to the technical field of agriculture, in particular to a quick seedling raising method for peach tree green stock and green branch cutting grafting. Background technique [0002] Prunus persica, a perennial deciduous tree belonging to Rosaceae, Prunus, and Amygdalius, is native to my country and has a cultivation history of more than 4,000 years. Peach has the characteristics of strong adaptability, early fruit, good yield and stability, lax requirements for soil conditions, and easy cultivation and management. It has spread all over the world, and its output is ranked first in the world. Except for Heilongjiang, other provinces, cities and districts have cultivation. The main economic cultivation provinces (cities) are Beijing, Tianjin, Shandong, Qingdao, Henan, Hebei, Hubei, Hunan, Zhejiang, Shanghai, Jiangsu, Liaoning, Shaanxi, Sichuan, Guizhou, Yunnan and other provinces. Peach juice is rich in flavor, attractive aroma, bright i...
