Selective breeding method of corylus heterophylla fisch

Abstract

The invention discloses a selective breeding method of corylus heterophylla fisch. The method is characterized by comprising the following steps: manually building a nursery: selecting a plot of hill or sloping field with fertile soil to build the nursery; selecting wild good clonal corylus heterophylla fisch and then transplanting into the nursery for propagation, wherein the cultivation season is late autumn or early spring, holes are dug in the nursery, seedlings are planted according to a plant row of 2*3 m, the specification of the holes is 0.5*0.5*0.5 m, 2.5 kg of chicken manure is applied in each hole, and the seedlings are thoroughly watered once; performing asexual propagation: performing cleft grafting in late April during grafting propagation, and performing layering propagation from the spring to the summer. The fruits of the strain have the characteristics of high yield, good fruit shape, pure mouthfeel, thin peel, small parts wrapped by seed coats, easiness in peeling, early maturity of the fruits and the like; the fruits are oak-shaped and thin in peel, have full nuts and are easy to shell to eat raw or eat after being processed.

Description

technical field [0001] The invention relates to a method for cultivating fruit trees, in particular to a method for breeding flat hazel trees. Background technique [0002] Flat hazel (Corylus heterophylla Fisch) is a plant of the genus Corylus in the family Corylaceae, and flat hazel is the species with the widest distribution, the most abundant resources, and the largest yield in the genus Corylus. Tieling City is a key production area of ​​flat hazel in my country. At present, the city's hazelnut base covers an area of ​​1.3 million mu, with an annual output of 40,000 tons. The area and output of Tieling's hazelnut base ranks first in the country. According to expert analysis, it accounts for about 70% of the national output, the output value of the primary industry has reached 1.12 billion yuan, the per capita income of hazelnut farmers in mountainous areas is 1,500 yuan, and the average income of 30,000 hazelnut farmers is nearly 40,000 yuan, accounting for 90% of the ...

Problems solved by technology

[0003] At present, the varieties of Tieling flat hazel are chaotic and mixed. With the development of society and changes in market demand, these varieties are mostly small in size, poor in processing quality, and low in market price. They are not suitable for production and development, and urgently need to be replaced.
