Sapium sebiferum cutting propagation method

Abstract

The invention discloses a sapium sebiferum cutting propagation method which comprises the following steps: collecting cuttings; preparing a cuttage seedbed, wherein the medium of the seedbed consists of peat, mushroom residues, mulberry twig powder and vermiculite in a weight ratio of 10:(1-3):(2-4):(3-5), and the medium is sterilized by using a 0.2% chlorothalonil solution in a spraying manner and is loaded into seedling raising cups; soaking and sterilizing cuttings in the 0.2% chlorothalonil solution, and soaking the cuttings into 1500mg / L ABT rooting medicinal liquid so as to obtain treated cuttings; performing cottage on the treated cuttings into the seedling raising cups, and thoroughly watering the medium after cottage, wherein the cottage depth of the cuttings is 3-4cm; performing cottage management and acclimatization and transplanting after cottage, thereby obtaining sapium sebiferum seedlings. After cutting cultivation is performed for 20-25 days, the rooting percentage can be up to 95% or above, and the survival rate of the cottage can be up to 90%. The method has the advantages of being simple to operate, low in cost, rapid in propagation speed, high in survival rate and the like, a great amount of sapium sebiferum seedlings can be rapidly obtained, and very good popularization values can be made.

Description

technical field [0001] The invention relates to the technical field of crop breeding, in particular to a cutting propagation method of Chinese tallow tree. Background technique [0002] Chinese tallow tree (Sapium sebiferum (L.) Roxb.) Candle tree, pepper tree. Chinese tallow is a deciduous tree belonging to the Euphorbiaceae family. Chinese tallow is a tree species with colored leaves. It is mainly distributed in the provinces and regions south of the Yellow River in China, and reaches Shaanxi and Gansu in the north. It can be used for killing insects, detoxifying, diuretic and laxative. For schistosomiasis, liver cirrhosis, ascites, difficulty in defecation and defecation, poisonous snake bites; for external use to treat boils, corns, mastitis, bruises, eczema, and dermatitis. Because Chinese tallow tree has great medicinal value, the market demand is increasing year by year, and the price increases accordingly. Since wild Chinese tallow tree cannot meet the demand of...

AI Technical Summary

Problems solved by technology

Cutting propagation can maintain the characteristics of the variety, and the cultivated plants grow faster than sowing seedlings, and can be cultivated into large seedlings in a short time, but the cutting seedlings obtained by cutting propagation have poor root systems and cannot form taproots. The survival rate of seedlings is low, and the life span is longer than that of sowing. Seedlings are short and less resistant to stress

At present, there are few studies on the cutting propagation of Chinese tallow tree. The existing cutting propagation methods of Chinese tallow tree have problems such as long seedling cultivation period, unstable rooting rate, few root systems of cutting seedlings, and weak disease resistance, which lead to low survival rate of seedlings after planting. The growth rate is slow, which is not conducive to the large-scale production of Chinese tallow tree cuttings
