Cultivation method of Ping'ou hybrid hazels

Abstract

The invention discloses a cultivation method of Ping'ou hybrid hazels. A strip dense planting method is mainly used; the management cost can be effectively reduced; land resources can be sufficientlyutilized; the fruit quality can be improved; and the yield per mu can be increased. By selective culture on new plants every year, due to nutrition supply by mother trees, tree bodies of the new plants grow rapidly, and phenomena of sunburn, rat bite and plant disease and insect pest invasion cannot occur on tree trunks; by utilizing growth of sprouting tillers of hazel trees, the utilization rateof the unit area of a hazel garden is gradually increased, and the space of the plant spacing is effectively utilized, the sprouting plants are expanded or densely planted; on one hand, the labor consumption can be reduced, and the yield can be increased; meanwhile, the consumption of fertilizers, water and pesticides can be reduced; and the condition of death of whole plants due to underground pests of tree trunks or roots, pesticide residues and the like can be reduced.

Description

Technical field [0001] The invention relates to the field of forestry planting, in particular to a cultivation method of Pingou hybrid hazel. Background technique [0002] Pingou hybrid is a new economic forest nut tree species and woody oil crop selected by distant hybridization, which was cultivated by scientific researchers in Liaoning Province of my country after 20 years, with Northeast wild Pingya filbert as the female parent and European filbert as the male parent. The tree species has the characteristics of cold resistance, strong adaptability, large fruit, high yield and stability. Low investment, quick effect and high economic effect. Cultivation practice has proved that the Pingou hybrid hazel will begin to bear fruit 2-3 years after planting, and it will enter the peak in 6-7 years. Fruiting period, with few pests and diseases, simple management, long life span, up to 30-50 years, is well received by growers and consumers, and the enthusiasm for development is extreme...

Problems solved by technology

[0003] In the cultivation process, tree structure is an important factor affecting the production and management of hazel orchards. Single-stem tree shape, short-stem multi-organized tree shape, and happy-shaped tree shape are the most common tree shape management in hazel orchard management; single-stem tree shape is the fruit tree shape. However, with the continuous expansion of the planting area and the growth of tree age, these tree shapes have problems of varying degrees: 2-4 year old hazel trees often suffer from sunburn, rat knocking, insect damage, and pesticides on the trunk. Damage and other reasons cause the bark of the trunk to crack and break, causing the tree to branch or the whole plant to die. Especially for large trees that have grown to 5-7 years, the whole plant is often caused by underground pests or drug residues in the cadres or roots. death, causing great confusion to producers
