Description
Technical Field
The invention relates to the technical field of planting production of Chinese toon sprouts, in particular to a dwarf cultivation method of Chinese toon.
Background
The Chinese toon is also named as Chinese toon sprout, Chinese toon head, spring seedling, etc. The root has two layers of bark, also called cortex toonae sinensis Radicis, which is native to China and is distributed in a wide range of south and north of Yangtze river, and is Meliaceae. Deciduous arbor, male and female heteroplant, compound leaves with even number of feathers, conicity, and amphimorphic flower white, and the fruit is elliptical capsule, wing-shaped seed, and the seed can be propagated. The tree body is tall and big, and is not only edible for Chinese toon sprouts, but also the preferable tree species for landscaping. Ancient times, the Chinese toon was called heaven and the ailanthus was called heaven. Chinese people have been used for a long time, and the Chinese generation is all over the south and north of the great river. The Chinese toon sprout is rich in nutrition, has the function of food therapy, and is mainly used for treating exogenous wind-cold, rheumatic arthralgia, stomachache, dysentery and the like.
Because the eating value of the Chinese toon is high, the eating of the Chinese toon sprouts can be long-term, and a large amount of Chinese toon is planted all over the country. But the yield of the Chinese toon sprouts is extremely low, the seasonality is very strong, and the price is extremely high. Only the tender shoots harvested in spring each year are relied on, and the market demand cannot be met at all. The company also carries out a large amount of planting development, and in the actual production process, the technical group of the company finds that the original greenhouse is improved by using a greenhouse planting technology to construct a special greenhouse which accords with the growth characteristics of the Chinese toons, so that the greenhouse is not limited by seasons and fills the season vacancy of the Chinese toon bud market. Meanwhile, the Chinese toon is subjected to dwarfing cultivation, so that the yield can be greatly improved, and the economic benefit is increased.
Therefore, research groups of the company develop a method for cultivating the dwarf cedrela sinensis, and apply for a patent with the patent number of 2015100013129 on 1 month and 5 days of 2015, and the patent technology brings a positive effect on the quality improvement and the yield improvement of the cedrela sinensis products of the company. However, since the dwarfing method is to breed lateral branches by pinching and topping from seedlings, the yield can be improved on the basis of the prior art, but the number of the lateral branches of a single plant is not large, so that the number of the single plant is increased to a limited extent, and the main stem is not large enough, cannot bear large external force during picking and is easy to break.
