Tea tree hardwood cutting seedling nutrient solution and preparation method thereof

Abstract

The invention belongs to the technical field of tea tree cultivation, and particularly relates to a tea tree hardwood cutting seedling nutrient solution formula and a preparation method thereof. The nutrient solution of the invention comprises 460-480 mg / L of N, 60-65 mg / L of P, 85-90 mg / L of K, 29-30 mg / L of Ca, 10-11 mg / L of Mg, 0.041-0.045 mg / L of Zn, 0.110-0.113 mg / L of F, 0.04-0.05 mg / L of Cu, 0.11-0.12 mg / L of Mn, and 0.11-0.12 mg / L of Be. The preparation method of the nutrient solution comprises the following steps: weighing 10 g of urea, 3 g of potassium dihydrogen phosphate, 1 g of calcium sulfate, 0.5 g of magnesium sulfate, 0.01 g of zinc sulfate, 0.03 g of ferric sulfate, 0.01 g of copper sulphate, 0.03 g of manganese sulfate, and 0.02 g of boric acid powder, adding water and dissolving to 10 L, preparing 1 L of 100-time mother liquor, taking out 10 mL from the mother liquor as needed, diluting into 1 L for use. The nutrient solution of the invention can promote growth of tea tree hardwood cutting seedlings; robust and qualified tea seedlings can be cultivated at the same year; the tea seedling survival rate from nursery is improved; the tea seedling transplanting survival rate is increased; the tea tree improved variety propagation coefficient is increased; and the invention plays an active role in the promotion of tea tree improved variety systems.

Description

technical field [0001] The invention belongs to the technical field of tea tree cultivation, and in particular relates to a tea tree hard branch cutting seedling-raising nutrient solution and a preparation method thereof. Background technique [0002] Tea tree hard branch cutting seedling raising is one of the methods of tea tree vegetative propagation and seedling raising, that is, in March before the spring tea, the branches are cut when the tea buds just germinate, and the cuttings go out through cutting, shading, water and fertilizer management. This hard branch cutting method is sufficient The branches of the next year are used, the production of spring tea is not affected, and the tea seedlings can be out of the garden in the same year. The disadvantages: the survival rate of cutting seedlings is low, the qualified rate of out of the garden is low, and the survival rate of transplanting is low, which affects the promotion of tea tree hard branch cutting seedlings. my cou...

[0002] Tea tree hard branch cutting seedling raising is one of the methods of tea tree vegetative propagation and seedling raising, that is, in March before the spring tea, the branches are cut when the tea buds just germinate, and the cuttings go out through cutting, shading, water and fertilizer management. This hard branch cutting method is sufficient The branches of the next year are used, the production of spring tea is not affected, and the tea seedlings can be out of the garden in the same year. The disadvantages: the survival rate of cutting seedlings is low, the qualified rate of out of the garden is low, and the survival rate of transplanting is low, which affects the promotion of tea tree hard branch cutting seedlings. my country is a big country in tea production, but the level of improved tea tree varieties is still relatively low. Through research on the formula of nutrient solution for tea tree hardwood cutting seedlings, a nutrient solution suitable for the growth of tea tree cutting seedlings has been formulated, which can more comprehensively meet the growth and development of tea seedlings. demand, the growth of tea seedlings is robust, this method is theoretically feasible, and after successful configuration, the application is easy to operate, easy to master, and low in cost. positive effects
