Description

A kind of compound seedling root humectant and preparation method thereof
Technical field
The invention belongs to the technical field of seedling root humectant, be specifically related to a kind of compound seedling root humectant and preparation method thereof, heel in for nursery stock, moisturizing carried out to seedling root in transportation.
Background technology
Planting trees, make our country green, improving the ecological environment is the fundamental state policy of China, is also the only way of promoting a conservation culture.China is the country of forest resources shortage, need carry out a large amount of afforested projects every year for this reason, and as 2013, the whole nation completed deserted mountain afforestation 610.01 ten thousand hectares, voluntary afforestation 25.2 hundred million strains, within 2014, completed afforestation 607.4 ten thousand hectares.Existing afforestation mainly adopts exposed root and shoot forestation and container seedling forestation 2 kinds of modes.Arid and soil depletion affect the key factor of growing into forest, and in order to improve survival rate, forestry technical personnel have employed multiple afforestation combination technique.One is study from the physiology of plant itself, ecology, hereditary feature, and selected floristics should possess strong adaptability, good stress resistance, well developed root system, plants easily, the characteristics such as survival rate is high; Two is take the multiple measure and utilize various drought-resistant water-preserving new material of retaining and conserveing soil moisture, and improves soil moisture, nutrition condition, to meet the demand of plant growth; Three are seedling transportation, the process of planting adopts multiple moist keeping measures, as heeled in, dipping in mud in time, shade, to keep seedling vigor.
It is a kind of common root system method for moisturizing in production of forestry that seedling root dips in mud, is that nursery stock a kind of minimizing used after the lifting of nursery is heeled in, the measure of root tissue water status evaporation transportation.Usual way stirs into muddy with common rural area soil and water to dip in root, root system surface is made to form mud layer to reduce root tissue water status evaporation, also there is the situation adding a small amount of water-loss reducer and root-inducing powder, phosphate fertilizer in mud, have and gather materials on the spot, feature easy to use.But because the mud adhesion formed with common soil is weak, exist dip in slurry uneven, be easy to the problems such as mummification comes off, therefore relative with afforestation effect poor to the protection of root system, cause many nursery stocks heeling in, affect survival rate due to dehydration in transportation.
Application number is the patent of invention of 201310083375.4, disclose " a kind of seedling wood flower humectant ", it discloses this humectant to be made up of super absorbent resin, root-growing agent, nutritional agents, bactericide repeatedly, and the proportioning of the phase that discloses each component is: acrylamide and acrylic acid first copolymer 96%, indolebutyric acid sodium salt 2%, nutrient solution 2%, bactericide 1%.Although this humectant can provide certain moisture-keeping function in seedling transportation, its moistening effect is still undesirable, and the nursery stock of institute's moisturizing also can be run off nutrient component, and cause nursery stock survival rate low, the seedling growth situation of survival is poor.
Summary of the invention
The present invention is that to solve the protected effect of humectant of the prior art to seedling root poor, causes nursery stock heeling in, affects the technical problem of survival rate in transportation due to dehydration, provide a kind of compound seedling root humectant and preparation method thereof.
The present invention is the technical scheme realizing the employing of its object:
A kind of compound seedling root humectant, this humectant is prepared from by following compositions: root-inducing powder 0.5-1 part, humic acid 3-6 part, benzimidazole germicide 10-15 part, super absorbent resin 20-30 part, potassium dihydrogen phosphate 10-20 part, sodium carboxymethylcellulose 100-200 part, coloring agent 15-30 part, talcum powder 450-900 part.

This humectant is prepared from by following compositions: root-inducing powder 0.8 part, humic acid 5 parts, benzimidazole germicide 12 parts, super absorbent resin 24 parts, potassium dihydrogen phosphate 13 parts, sodium carboxymethylcellulose 160 parts, coloring agent 22 parts, talcum powder 650 parts.
This humectant is prepared from by following compositions: root-inducing powder 0.6 part, humic acid 4.5 parts, benzimidazole germicide 13 parts, super absorbent resin 25 parts, potassium dihydrogen phosphate 15 parts, sodium carboxymethylcellulose 132 parts, coloring agent 26 parts, talcum powder 690 parts.
Described root-inducing powder is any one in water-soluble 6-8 ABT root-inducing powder.
Described humic acid is fulvic acid pulvis.
Described benzimidazole germicide is 50% powder of carbendazim.
Described coloring agent is reactive brilliant red or acid scarlet pigment.
The particle diameter of described super absorbent resin is 0.3-0.8mm, and described super absorbent resin is acrylamide and acrylate copolymer.
A preparation method for compound seedling root humectant, comprises the following steps:
(1), root-inducing powder, humic acid, bactericide, super absorbent resin, potassium dihydrogen phosphate, sodium carboxymethylcellulose, coloring agent, talcum powder is taken in the ratio number of composition, and the coloring agent taken is divided into three parts, be respectively the first coloring agent, the second coloring agent and the 3rd coloring agent, talcum powder is divided into three parts, be respectively the first talcum powder, the second talcum powder and the 3rd talcum powder, for subsequent use;
(2), get root-inducing powder in step (1) and the water-soluble solution of the first coloring agent, and then add the first talcum powder wherein, stir, naturally drying in the shade is placed on lucifuge place and preserves, and obtains pulvis A, for subsequent use;
(3), get humic acid in step (1) and the water-soluble solution of the second coloring agent, and then add the second talcum powder wherein, stir, naturally drying in the shade is placed on lucifuge place and preserves, and obtains pulvis B, for subsequent use;
(4), get bactericide in step (1) and the water-soluble solution of the 3rd coloring agent, and then add the 3rd talcum powder wherein, stir, naturally drying in the shade is placed on lucifuge place and preserves, and obtains pulvis C, for subsequent use;
