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 the quality of germination rate, emergence rate and the seedling of nursery stage, raising seed, floating seedlings becomes a kind of emerging seedling raising manners.Floating seedlings is that the foam cave dish that lightweight seedling medium is housed is floated on the water surface, and seed is sowed in matrix, and rice shoot is taken root growth in seedling medium, and can from matrix and water bed, absorb the seedling-cultivating method of moisture and nutrient.Start from late 1980s, American Tobacco adopts floating seedlings method to grow seedlings.With traditional seedling method comparison, it has can reduce transplanting recruitment, save the land used of growing seedlings, be convenient to the management of cigarette seedling, be conducive to cultivate strong sprout, improve the advantages such as planting percent.
What report was maximum at present is that flowers, tobacco adopt 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, such as application number is 201210134287.8 and 01107070.6 Chinese patent application, but these disclosed nutritive liquid for floating breeding at present, and be not suitable for the floating seedlings of Chinese sorghum, especially for Luzhou Gulin, be mainly distributed in height above sea level 500m-1000m region, between Chinese sorghum nursery stage, temperature is low, Chinese sorghum rice shoot growing way is slow, the problem that transplanting time is postponed; The region of height above sea level 500m, conventional seedbed system started to grow seedlings about annual March 20, and temperature is even lower 10 ℃ of left and right, with height above sea level, constantly raises, and temperature constantly reduces, and rice shoot growing way is more slow, affects transplanting time.
For these situations, present inventor has carried out large quantity research, obtained good progress, and introduced a kind of new Chinese sorghum nutritive liquid for floating breeding on the science and technology > > of < < farmers', consisting of of this nutrient solution: every square metre with (150 grams of N:P:K=15:15:15 composite fertilizers+brave strong (water-soluble neutral compound fertilizer of chelating state, plant can absorb under 6-8 ℃ of cryogenic conditions) 1 gram of 5 grams+1 gram+Kai Puke of hundred fertilizer (humic acid) (alginic acid water soluble fertilizer), this nutrient solution coordinates other culture techniques, can solve seedling strong, Miao Qi, the problems such as planting percent height, but, still there is following shortcoming in this nutrient solution: 1, the formula 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 are all finished product fertilizers, cost is higher, 3, thoroughly power and diffusibility are undesirable, this nutrient solution may due to pigment and proportioning not good, 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 applicable 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, weigh, evenly mixing and get final product by proportioning.
The application passes through great many of experiments, adjust composition and the proportion relation of nutrient solution, and increase the trace elements such as appropriate boron, magnesium, zinc, copper, and reduce nutritional deficiency symptom, can allow plant synchronously absorb 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.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, weigh, evenly mixing and get final product by proportioning.
This programme can be so that effect reaches optimum.
As preferably: in N, ammonia nitrogen content is 0.9%～1.1 %.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 % in 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% in K.The water soluble oxidized potassium of this content is more conducive to form suitable chelate, and is conducive to control cost.
Two of object 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 adopting is: in every square meter nutrition pond, use this nutrient solution 90g～120g, wherein the nutrition pond depth of water 10～15cm.The nutrition pond of this altitude range can meet the needs of Chinese sorghum floating seedlings, and is conducive to control cost.
In sum, owing to having adopted technique scheme, the invention has the beneficial effects as follows: adopt the formula of nutrient solution of the present invention to form and ratio, owing to mutually acting synergistically between each nutrient, while making to grow seedlings, the penetration of nutrient solution and diffusibility strengthen greatly, thereby the quality that has greatly shortened the seeding stage and improved emergence rate and emerged, adopt raw material mix composite and avoid adopting finished product fertilizer simultaneously, and preparation method does not simply need the operations such as chelating just can make plant good absorption, has further reduced cost; And this nutrient solution is more suitable for high height above sea level low temperature and grows seedlings.
