Abstract
The invention discloses a broomcorn floating-seedling nutrient solution. The broomcorn floating-seedling nutrient solution consists of, by weight, N 12.5-13.5%, P 11.5-12.5%, K 2-20%, alginic acid 2-3%, humic acid 2-3%, boron 0.4-0.6%, magnesium 0.1-0.12%, zinc 0.1-0.12%, copper 0.08-0.11% and the balance water and is prepared by weighing components according to the proportion and mixing the components evenly. By adopting the broomcorn floating-seedling nutrient solution, the seepage force and the diffusivity of the nutrient solution are greatly enhanced in seedling cultivation, accordingly a seedling emergence period is shortened greatly, the emergence rate and the emergence quality are improved, and the cost is reduced. In addition, the nutrient solution is suitable for high-altitude low-temperature seedling cultivation.
Description
Technical field
The present invention relates to a kind of nutritive liquid for floating breeding, particularly a kind of Chinese sorghum nutritive liquid for floating breeding.
Background technology
Along with agrotechnical development, seedling growing process also presents fast-developing situation, and in order to shorten nursery stage, to improve the quality of germination rate, emergence rate and the seedling of seed, floating seedlings becomes a kind of emerging seedling raising manners.Floating seedlings is that the foam cave dish that will the lightweight seedling medium be housed floats on the water surface, and seed is sowed in the matrix, and rice shoot is taken root growth in seedling medium, and can absorb the seedling-cultivating method of moisture and nutrient from matrix and water bed.Start from late 1980s, American Tobacco adopts the floating seedlings method to grow seedlings.Compare with traditional seedling method, it has can reduce the transplanting recruitment, save the land used of growing seedlings, be convenient to the cigarette seedling manages, is conducive to cultivate the advantages such as strong sprout, raising planting percent.
What report was maximum at present is that flowers, tobacco are adopted the floating seedlings technology.For floating seedlings, the technology of its most critical comprises levitating seed-cultivating interstitial substance, nutritive liquid for floating breeding etc., wherein, nutritive liquid for floating breeding is particularly important for the improvement of nursery stage, emergence rate and the quality of emerging, it is 201210134287.8 and 01107070.6 Chinese patent application such as application number, but present these disclosed nutritive liquid for floating breeding, and be not suitable for the floating seedlings of Chinese sorghum, especially mainly be distributed in height above sea level 500m-1000m zone for the Luzhou Gulin, temperature is low between the Chinese sorghum nursery stage, Chinese sorghum rice shoot growing way is slow, the problem that transplanting time is postponed; The zone of height above sea level 500m, conventional seedbed system began to grow seedlings about annual March 20, and temperature constantly raises with height above sea level about 10 ℃ even lower, and temperature constantly reduces, and the rice shoot growing way is more slow, affects transplanting time.
For these situations, the present inventor has carried out large quantity research, obtained good progress, and on " farmers''s science and technology ", introduced a kind of new Chinese sorghum nutritive liquid for floating breeding, consisting of of this nutrient solution: every square metre with (N:P:K=15:15:15 composite fertilizer 150 restrains+brave strong (the water-soluble neutral compound fertilizer of chelating attitude, plant can absorb under 6-8 ℃ of cryogenic conditions) 5 gram+hundred fertilizer (humic acid) 1 gram+Kai Puke (alginic acid water soluble fertilizer), 1 gram, this nutrient solution cooperates other culture techniques, it is strong to solve seedling, Miao Qi, the problems such as planting percent height, but, still there is following shortcoming in this nutrient solution: 1, the prescription of possible nutrient solution forms and ratio does not reach optimum, its seeding stage, emergence rate and the quality of emerging are still dissatisfied; 2, this nutrient solution has adopted several finished product fertilizer to fill a prescription, because brave strong, hundred fertilizer, Kai Puke all are finished product fertilizers, cost is higher; 3, power and diffusibility are undesirable thoroughly, and this nutrient solution may be because pigment and proportioning thereof be not good, and the penetration of plant and diffusibility are all undesirable.
Summary of the invention
One of goal of the invention of the present invention is: for the problem of above-mentioned existence, provide a kind of and address the above problem, can effectively shorten the seeding stage, improve emergence rate and nutrient solution that grow seedlings quality and suitable low temperature with low cost are grown seedlings.
The technical solution used in the present invention is such: a kind of Chinese sorghum nutritive liquid for floating breeding, and by weight percentage, its composition is:
N：12.5～13.5%；
P：11.5～12.5%；
K：2～20%；
Alginic acid: 2～3%;
Humic acid: 2～3%;
Boron: 0.4～0.6%;
Magnesium: 0.1～0.12%;
Zinc: 0.1～0.12%;
Copper: 0.08～0.11%;
All the other are water, by the proportioning weighing, and evenly mixing and get final product.
The application passes through great many of experiments, adjust composition and the proportion relation of nutrient solution, and increase the trace elements such as an amount of boron, magnesium, zinc, copper, and reduce nutritional deficiency symptom, can allow plant absorb synchronously simultaneously, under 8 ℃ of cryogenic conditions, still can be by the nutritious fertilizer of root absorption, penetration and diffusibility strengthen greatly, make the root mass of crop be easy to absorb, rapid permeability is to the root of crop, and how white again the root hair of root system is.The leaf look dark green, and height of seedling is large, and stem is thick, strong, and main root is many and grow, and fibrous root is many; Resistance reaches strong sprout, strong seedling standard, further improves seedling quality, strengthens the resistance of rice shoot;
As preferably: by weight percentage, its composition is:
N 13.4%, P 12%, K 20%, alginic acid 2%, humic acid 2%, boron 0.5%, magnesium 0.1%, zinc 0.1%, copper 0.1%,
All the other are water, by the proportioning weighing, and evenly mixing and get final product.
This programme can be so that effect reaches optimum.
As preferably: ammonia nitrogen content is 0.9%～1.1 % among the N.The ammoniacal nitrogen of this content is more conducive to form suitable chelate, and is conducive to control cost.
As preferably: water-soluble phosphoric anhydride 0.9%～1.1 % among the P.The water-soluble phosphoric anhydride of this content is more conducive to form suitable chelate, and is conducive to control cost.
As preferably: water soluble oxidized potassium 0.9%～1.2% among the K.The water soluble oxidized potassium of this content is more conducive to form suitable chelate, and is conducive to control cost.
Two of purpose of the present invention is to provide a kind of application of above-mentioned Chinese sorghum nutritive liquid for floating breeding, and the technical scheme that adopts is: use this nutrient solution 90g～120g, wherein the nutrition pond depth of water 10～15cm in every square meter nutrition pond.The needs of Chinese sorghum floating seedlings can be satisfied in the nutrition pond of this altitude range, and are conducive to control cost.
In sum, owing to adopted technique scheme, the invention has the beneficial effects as follows: adopt the prescription of nutrient solution of the present invention to form and ratio, owing to mutually act synergistically between each nutrient, the penetration of nutrient solution and diffusibility strengthen greatly during so that grow seedlings, thereby the quality that has greatly shortened the seeding stage and improved emergence rate and emerged, adopt simultaneously raw material to mix composite and avoid adopting finished product fertilizer, and the preparation method does not simply need the operations such as chelating just can make the plant good absorption, has further reduced cost; And this nutrient solution more is applicable to high height above sea level low temperature and grows seedlings.
