Cultivation Method of Toona sinensis Main Trunk Cable Pulling Dwarfing and Dense Planting

Abstract

The invention discloses a method for cultivating Chinese toon with cable-drawn dwarfing and dense planting, which belongs to the field of plant cultivation. The invention selects red oil with excellent provenance, seedling height of 1 to 2 meters, seedling age of 1 to 2 years, robust growth, and no pests and diseases Tsubaki or black oil Tsubaki seedlings are planted according to the cultivation mode of double rows with large row spacing and small plant spacing. After the sprouts are picked 2 to 3 times in the same year, the main trunk is cable-pulled by the method of binding to promote multiple side branches and cultivate multiple main branches. Tree shape, combined with plastic pruning technology to control the tree height at a reasonable height. This method can not only reduce the nutrient consumption of the tree body, increase the yield of Chinese toon sprouts, shorten the cultivation cycle of dwarfed and densely planted trees, but also effectively reduce the difficulty of picking Chinese toon buds, improve work efficiency, and to a certain extent, reduce the The probability of occurrence of pests and diseases.

Description

technical field [0001] The invention relates to a method for dwarfing and densely planting Chinese toon for growing vegetables in the field, and belongs to the field of plant cultivation. Background technique [0002] Chinese toon has a history of thousands of years of cultivation and consumption in my country. It is a unique "forest vegetable" tree species in China. This tree species has a wide distribution range, strong adaptability, and a tall tree. Its young buds and leaves are rich in soluble sugar, protein, and vitamins. , a variety of amino acids and flavonoids and other nutrients, with high food and medicinal value. Studies have shown that Chinese toon has a certain therapeutic effect, and can treat or slow down diseases such as exogenous wind-cold, rheumatic arthralgia, stomach pain, and dysentery. At present, Chinese toon is mainly used as a vegetable in domestic fields. However, Toona sinensis itself is a kind of tall tree with fast growth rate. Under the traditi...

AI Technical Summary

Problems solved by technology

However, Toona sinensis itself is a kind of tall tree with fast growth rate. Under the traditional mode of cultivation, the tree height of 1-year-old sowing seedlings will exceed 3 meters after 2 to 3 years. very large

In recent years, the method of stem cutting combined with plastic pruning is mainly used in China to realize dwarf and dense planting cultivation. This method has great damage to the tree body and high requirements on soil fertility. It takes at least 3 to 5 years to cultivate a tree shape with multiple main branches. After drying, the wound of the tree body is easy to be infected, and the phenomenon of pests and diseases is more serious.
