Cutting and rapid propagating method for sapindus mukorossi Gaertn.

Abstract

The invention discloses a cutting and rapid propagating method for sapindus mukorossi Gaertn.. The method comprises the following steps that cutting shoots are collected; cutting seedling beds are prepared, wherein a medium of the seedling beds is prepared from peat, mushroom residues, mulberry shoot powder and vermiculite according to the weight ratio of 10:(2-4):(3-4):(4-5), and the medium is disinfected by spraying a chlorothalonil pesticide solution with the concentration of 0.4% to the medium and then contained in seedling raising cups; the cutting shoots are disinfected by being soaked in the chlorothalonil pesticide solution with the concentration of 0.4% and then put into an ABT rooting pesticide solution with the concentration of 500 mg/L to be soaked, and the processed cutting shoots are obtained; the processed cutting shoots are cut into the seedling raising cups, the depth that the cutting shoots are inserted into the medium is 2-4 cm, and the medium is drenched with water after cutting is conducted; cutting managing, seedling hardening and transplanting are conducted after cutting is conducted, and then sapindus mukorossi Gaertn. seedlings can be obtained. According to the method, after cutting and culturing are conducted for 20-25 days, the rooting rate reaches 95% or above, and the cutting survival rate can reach 90%; the advantages of being easy to operate, low in cost, high in propagating speed and survival rate and the like are achieved, a large quantity of sapindus mukorossi Gaertn. seedlings can be rapidly obtained, and a very good popularization value is achieved.

Description

technical field [0001] The invention relates to the technical field of crop breeding, in particular to a cutting and rapid propagation method of Sapindus sapindus. Background technique [0002] Sapindus mukorossi Gaertn.), also known as Sapindus mukorossi Gaertn.), aliased as Sapindus mukorossi, Sapindus oleifera, Kuzai tree, Huangmu tree, Mulang tree, Youluo tree, Washing fruit, etc. Sapindus fruit peel contains saponin, which can replace soap, and the wood can be used as box board and wooden comb. Its roots, twigs, leaves, and seeds are bitter, slightly pungent, and cold in nature. For diphtheria, seminal vesicle disease, stranguria, frequent urination, clearing heat, eliminating phlegm, eliminating stagnation, killing insects, sore throat, coughing, dyspepsia, leucorrhea, malnutrition, sores and ringworm, swelling and poisoning, etc. Because Sapindus has great medicinal value, the market demand is increasing year by year, and the price is increasing accordingly.

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 Sapindus chinensis. The existing cutting propagation methods of Sapindus sativa have problems such as long seedling cultivation period, unstable rooting rate, less root system of cutting seedlings, and weak disease resistance, which lead to problems after seedlings are planted. The low survival rate and slow growth rate are not conducive to the large-scale production of Sapindus cutting propagation
