Cultivation method of cedrela sinensis seedling

Abstract

The invention relates to the field of plant cultivation, in particular to a cultivation method of a cedrela sinensis seedling. The cultivation method comprises the following steps: (a) in every February, selecting a mature cedrela-sinensis tree with good growth; (b) respectively cutting off a main root of the cedrela-sinensis tree into sections at the 50-80cm position, the 110-150cm position and the 160-180cm position from the root part, wherein each section is 10-30cm; (c) applying aqueous solution prepared by 1% of urea, 10% of rooting hormone, 0.5% of potassium permanganate and 5% of potassium phosphate at the root-broken part in the step (b) for 2-3 times every week; (d) when the root germinates to be 1-1.5m, transplanting the cedrela sinensis seedling. The cultivation method has the advantages that by the technology for adopting cut roots to cultivate the seedling, not only is the variation of the newborn cedrela sinensis seedling prevented, but also the loss caused by no growing of cedrela sinensis on the cedrela-sinensis tree with the age being 6-9 years is prevented, so that the economic value is increased.

Description

technical field [0001] The invention relates to the field of plant cultivation, in particular to a method for growing seedlings of Chinese toon. Background technique [0002] Toona sinensis is a special food in northern Anhui, especially black oil toon, which is loved by many people for its mellow taste and rich nutrition. However, the black oil toon tree has strict requirements on growth conditions. If toon bud seeds are used to raise seedlings, the survival rate of seedlings Less than 40%, not only the survival rate is low, but also it is easy to cause the variation of the seedlings. The black oil toon will mutate into the red oil toon. Now some people use the technology of rooting seedlings. However, the roots of the Chinese toon are taken out and transplanted for seedling cultivation. Its growth environment, seedlings are also prone to variation, causing the taste and nutritional value of the Chinese toon grown from the cultivated Chinese toon tree to be reduced. [000...

Problems solved by technology

[0004] In order to solve the above-mentioned shortcomings of the prior art, the present invention provides a method for growing seedlings of Toona sinensis, which solves the problems that the survival rate of Chinese toon seedlings was low, easily mutated, and the age of the tree was 6-9 years and could not produce economic benefits.
