Cedrela sinensis trunk obliquely-pulled dwarfing and compact planting cultivation method

Abstract

The invention discloses a cedrela sinensis trunk obliquely-pulled dwarfing and compact planting cultivation method, and belongs to the field of plant cultivation. According to the method, red oil cedrela sinensis seedlings or black oil cedrela sinensis seedlings which are excellent in seed source, 1-2 meters in seedling height, 1-2 years in seedling age, strong in growth and free of plant diseases and insect pests are selected, and the seedlings are planted in a double-line large-line-spacing and small-row-spacing cultivation mode. After 2-3 times of sprout picking in the current year, obliquely pulling is carried out on trunks in a binding method so as to promote the seedlings to grow more lateral branches; the seedlings are cultivated in multiple-main-branch dwarfing tree shapes and trees are controlled at a reasonable height by combining the pruning technology. According to the method, nutrient consumption of tree bodies can be reduced, the yield of cedrela sinensis sprouts can be improved, and the cultivation period of dwarfing and compact planting of tree shapes can be shortened; meanwhile, the picking difficulty of the cedrela sinensis can be effectively reduced, work efficiency is improved, and probabilities of plant diseases and insect pests on the tree bodies can be reduced to a certain extent.

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...

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.
