Taxus chinensis cutting seedling soaking solution

Abstract

The invention discloses a taxus chinensis cutting seedling soaking solution. The taxus chinensis cutting seedling soaking solution comprises the following raw materials in parts by weight: 1.5-2 partsof naphthylacetic acid, 4-6 parts of indolebutyric acid, 0.1-0.15 part of brassinolide, 8-12 parts of triacontanol, 1-3 parts of sodium bromoethanesulphonate, 0.8-1.0 part of alliin, 2-3 parts of potassium benzoate, 80-90 parts of filling-stage corn grains, 15-20 parts of prepared rehmannia, 15-20 parts of dwarf lilyturf tuber, 13-17 parts of coconut bran, 10-15 parts of palm oil, 10-15 parts ofpine needle powder, 8-12 parts of potassium dihydrogen phosphate, 8-12 parts of urea, 6-10 parts of rosin, 5-8 parts of a sterilizing preservative, 5-8 parts of carboxymethyl chitosan, 3-6 parts of sodium alginate and 2-3 parts of sodium polyacrylate. After the taxus chinensis cutting seedling soaking solution soaks a cutting root, a layer of nutritional film can be formed so as to prevent loss ofnutrients adsorbed on the surface of the root; meanwhile, the taxus chinensis cutting seedling soaking solution can effectively promote rooting of a cutting branch, can promote division and differentiation of a plant cell, can increase the stress resistance of the branch and can increase the rooting speed of an osmanthus branch.

Description

technical field [0001] The invention belongs to the technical field of tree planting, in particular to a yew cutting seedling soaking solution. Background technique [0002] Yew is a shallow-rooted plant with inconspicuous main roots and well-developed lateral roots. It is a shade-tolerant tree species that likes warm and humid climates. It usually grows in relatively humid places in the hinterland at the foot of mountains. It naturally grows in acidic soil rich in humus in valleys, streams, and gentle slopes at an altitude of 1,000 meters or below 1,500 meters. It requires higher fertility yellow soil, yellow brown soil, neutral soil, and calcareous soil. It is resistant to drought and barrenness, and it is not tolerant to low-lying water. It has strong adaptability to climate, with an average annual temperature of 11-16°C, and the lowest extreme value can reach -11°C. It has strong germination ability, and there are many sprouting twigs on the trunk. Due to the slow grow...

Problems solved by technology

In addition, yew has dioecious plants, more males and fewer females, low seed germination rate, and slow growth. Many biological characteristics limit the development of natural populations and exacerbate its endangered situation.

Therefore have only to adopt artificial measure to cultivate (cutting), strengthen the introduction and cultivation technology research, to expand the total amount of resources, expand its planting scope, could better solve this problem of resource shortage, the existing cutting technology yew root takes root slowly, Slow nutrient absorption and low survival rate
