One soilless raising seedling substrate for cotton and compound method thereof
(1) technical field
The present invention relates to a kind of soilless raising seedling substrate, particularly a soilless raising seedling substrate for cotton and compound method thereof.
(2) background technology
China is world textile big country, also is world textile product big export country.Cotton has become China after soybean, edible oil, large agricultural-food of the third-largest import at present.In case international industry is controlled market, the cotton industry of China will face great risk.Cotton is the requisite of people's lives, also is important industrial raw material and material, plays an important role international and domestic being in great demand in the national economic development.In recent years, the pay of migrant rural workers improves constantly, wheat, seeding corn and other crops mechanization production level obviously improve, and production cost changes not obvious, and the Cotton Production recruitment is many, mechanization degree is low, the recruitment of tradition seeding raising technology is many, and labor capacity is large, and it is slow to send out seedling, production cost increases, and cotton phenomenon not as doing manual work generally occurred planting.The invention non-soil culture can replace numerous and diverse traditional feeding block seedlings raising, can greatly reduce labour intensity, reduces the labor force and drops into, and reduces production costs, for the peasant increases more income; Substrate seedling can be good at improving Quality of Seedlings simultaneously, has good production-increasing function.The raising seedling of cotton matrix species is more at present, and great majority are all take vermiculite as main raw material, but main cotton growing area lacks vermiculite, and the transportation raw materials cost is higher again.
(3) summary of the invention
The present invention is in order to remedy the deficiencies in the prior art, and a kind of soilless raising seedling substrate for cotton and compound method thereof of with low cost, easy to operate, stable in properties is provided.
The present invention is achieved through the following technical solutions:
One soilless raising seedling substrate for cotton, its special character is: take Klinit dregs as main raw material, be equipped with unslaked lime, urea, diammonium phosphate, Repone K, zinc sulfate, borax, carbendazol wettable powder and be prepared from by a certain percentage.
Soilless raising seedling substrate for cotton of the present invention is made by the component of following weight percent:
Klinit dregs (water content≤13%) 85%-90%
Unslaked lime 2.0%-3.0%
Urea 2.0%-3.0%
Diammonium phosphate 2.0%-3.0%
Repone K 2.5%-3.0%
Zinc sulfate 0.5%-1.5%
Borax 0.5%-1.5%
Carbendazol wettable powder 0.5%-1.0%.
The compound method of soilless raising seedling substrate for cotton of the present invention comprises the steps:
(1) spray solution that 2.6 kilograms of unslaked limes and 3.4 kg of water is fully reacted rear formation stirs on 87 kilograms of Klinit dregs, stacks 2-3 hour with neutralization acidic substance wherein, then spreads out and dries, and the A that packs into bag is for subsequent use;
The chemical reaction that occurs: CaO+H

(2) 2.6 kilograms of urea, 2.4 kilograms of diammonium phosphate, 2.6 kilograms of Repone K, 1 kilogram of zinc sulfate, 1 kilogram of borax, 0.8 kilogram of carbendazol wettable powder are stirred, the B that packs into bag is for subsequent use;
When (3) growing seedlings A, B bag is evenly mixed, namely make this matrix.
Using method: this matrix is mixed the composition seedbed with clean river sand in 1: 10 ratio can grow seedlings.
Klinit dregs is the waste material that is produced as the raw material production Xylitol take corn cob.Klinit dregs has aboundresources, with low cost, have again simultaneously stronger heat, water storage soil moisture conservation and Anion-adsorption effect, and have the multiple actions such as the ventilation property that improves soil, fertilizer conservation, water conservation, water storage, ventilative and mineral manure.Utilize Klinit dregs to be main raw material, with the main nutrient elements such as N, P, K and Fe, Mn, Cu, Zn, the various trace elements science compatibilities such as B, Mo, select appropriate production technology, preparation raising seedling of cotton matrix is practicable take Klinit dregs as main raw material.
The beneficial effect of soilless raising seedling substrate for cotton of the present invention and compound method thereof, the one, with low cost, reduced the input of growing seedlings; The 2nd, easy to operate, the Klinit dregs particle is fine and smooth, and process for preparation is simple; The 3rd, the Klinit dregs stable in properties, non-efflorescing cementitious, easy preservation is made raw material matrix energy prolonged preservation with Klinit dregs; The 4th, Klinit dregs belongs to biological raw material, industrial residue, and wide material sources, fast, the safety and environmental protection of speed of circulation have alleviated again environmental pollution simultaneously; The 5th, nursery effect is good, and seedling rate is high, can reach more than 90%, and seedling is healthy and strong, neat, disease-free, quality is good.
(4) embodiment
Embodiment 1:
The compound method of soilless raising seedling substrate for cotton comprises the steps:
(1) spray solution that 2.6 kilograms of unslaked limes and 3.4 kg of water is fully reacted rear formation stirs on 87 kilograms of Klinit dregs, stacks 2-3 hour with neutralization acidic substance wherein, then spreads out and dries, and the A that packs into bag is for subsequent use;
(2) 2.6 kilograms of urea, 2.4 kilograms of diammonium phosphate, 2.6 kilograms of Repone K, 1 kilogram of zinc sulfate, 1 kilogram of borax, 0.8 kilogram of carbendazol wettable powder are stirred, the B that packs into bag is for subsequent use;
When (3) growing seedlings A, B bag is evenly mixed, namely make this matrix.
Using method: this matrix is mixed the composition seedbed with clean river sand in 1: 10 ratio can grow seedlings.
