Transformation method for low-yield Camellia oleifera Abel forests

Abstract

The invention discloses a transformation method for low-yield Camellia oleifera Abel forests, and belongs to the technical field of forest culture and management. By taking the technical measures of pruning, reclamation, fertilization, canopy replacement and the like for old Camellia oleifera Abel forests, the Camellia oleifera Abel yield of the Camellia oleifera Abel forests is substantially increased, and the problems that for the old Camellia oleifera Abel forests, the number of parasitic branches is large, the forest form declines gradually, soil fertility is reduced, the yield is low and unstable, the land output rate is low, and land resources are wasted are effectively solved. The method includes the concrete steps of shaping and pruning, proper thinning, full cultivation and scarification reclamation, summer shallow hoeing and intertillage, fertilization, canopy replacement, sprout regeneration, pre-planting regeneration, enhancement of disease and pest prevention and treatment, and bee breeding in the forests. The method has the advantages that by taking the technical measures for the old Camellia oleifera Abel forests, the plant type of the Camellia oleifera Abel forests is rationalized, the number of robust branches is large, forest stand nutrition conditions are improved, soil fertility in the forests is improved, moisture is accumulated, diseases and pests are reduced, root extension is promoted, the pollination rate is increased, and therefore the yield of the Camellia oleifera Abel forests is substantially increased; the Camellia oleifera yield is increased to 35-45 kg per mu from 5-8 kg per mu and is increased by 5-8 times, the yield is high and stable, and therefore the high and stable yield effect is achieved.

Description

technical field [0001] The invention discloses a method for transforming low-yield economic forests, in particular to a method for transforming camellia oleifera forests with low yield, and belongs to the technical field of silviculture. Background technique [0002] Camellia oleifera, scientific name: Camellia oleifera Abel, belongs to Theaceae, evergreen small tree. It is named because its seeds can be used to extract oil (tea oil) for consumption. Camellia oleifera is a treasure for the whole body. Camellia oil is recognized as one of the best edible oils in the world. Its content of unsaturated fatty acids, linolenic acid and vitamin E is higher than that of olive oil. It is very beneficial to promote people's health. It is listed as a The healthy edible oil that is mainly promoted, with the increasing demand for global green consumption, camellia oil is favored by consumers, and the domestic and foreign markets are in short supply. At the same time, it is also a kind ...

AI Technical Summary

Problems solved by technology

[0003] Camellia oleifera is mainly produced in the southern provinces of my country, and has a long history of cultivation. Most of the camellia oleifera forests in the main production areas are planted from before liberation to the early stage of liberation. Many trees are over 40 years old, and some are 80, 90 or even 100 years old. Above, there are many parasitic branches, forest facies gradually decline, soil fertility declines, low and unstable yield, low land output rate, waste of land resources
