Background technology
Fertilizer is as the grain of supply plant desired nutritional, it has also become the important foundation of modern agricultural development.A large amount of uses of the conventional composite fertilizer based on N P and K, cause soil and harden seriously, destroy crop products quality, environment causes substantial amounts of pollution simultaneously at present.Although farm manure can overcome disadvantage mentioned above, but farm manure is thorough because of heap fermentation, causes the problem such as propagation of pathogenic microorganism and parasite (ovum).Therefore, searching can replace conventional composite fertilizer, and the novel biological fertilizer with farm manure Effect of improving soil is the most necessary.Alga fertilizer has been polymerized various active material in ocean, possesses comprehensive nutrition, disease-resistant yield-increasing, many advantages such as native, nuisanceless of living, is the good fertilizer really meeting modern agricultural development direction.Alga fertilizer is to cereal crops such as corn, paddy rice, barley, wheat, soybean, the industrial crops such as cotton, tobacco, mulberry tea and horticulture are particularly had bigger effect of increasing production and economic benefit by the fruit trees such as the vegetable crops such as pachyrhizus, potato, peanut, pea, cucumber, tomato, eggplant, Chinese cabbage, ginger, watermelon, celery, shallot, garlic and apple, pears, peach, persimmon, citrus, banana, mango, grape, Chinese date.In a word, alga fertilizer is fertile as a new generation's natural marine organism, includes the incomparable multiple high activity composition of terrestrial plant and nutrient, has obvious effect of increasing production and extremely strong degeneration-resistant effect.
Summary of the invention
It is an object of the invention to provide a kind of water soluble fertilizer containing alginic acid and various nutrient elements and preparation method thereof, the method organic fertilizer and inorganic fertilizer combine, it it is full water soluble fertilizer, the disease-resistant high-output stress-resistance of alginic acid, nutrient is complete, instant effect, is applicable to multiple fertilization mode, and Effect of improving soil is obvious.
It is an object of the invention to be achieved through the following technical solutions:
Containing alginic acid and the water soluble fertilizer of various nutrient elements, described fertilizer is the chemical fertilizer of crops and plant, comprises following components:
Containing highly active alginic acid；Mixture containing water-soluble inorganic nitrogen, phosphorus and potassium or compound；Containing water-soluble calcium, magnesium elements and other inorganic matter；Containing water-soluble copper, iron, manganese, zinc chelated microelements and molybdenum, the inorganic salts of boron element；
The above-mentioned water soluble fertilizer containing alginic acid and various nutrient elements is to select said components to process by following element content range:
(1) in this water soluble fertilizer, alginic acid content summation is weight 3%；
(2) in this water soluble fertilizer, a great number of elements N, P2O5、K2O content summation is weight 57%；
(3) in this water soluble fertilizer, moderate-element Ca, Mg content summation is weight 1%；
(4) in this water soluble fertilizer, the content summation of trace element Cu, Fe, Mn, Mo, Zn, B is weight 0.64%.
Described containing alginic acid and the water soluble fertilizer of various nutrient elements, described raw material: in the water soluble fertilizer containing alginic acid and various nutrient elements, nitrogen is from urea, Agricultural Potassium Nitrate；Phosphorus derives from MAP, Diammonium phosphate (DAP), potassium dihydrogen phosphate；Potassium derives from potassium dihydrogen phosphate, Agricultural Potassium Nitrate；Calcium source is in calcium nitrate；Magnesium derives from epsom salt；Boron derives from borax；Molybdenum derives from sodium molybdate；Copper, iron, manganese, the chelate of zinc are processed by EDTA chelating agent.
Water soluble fertilizer preparation method containing alginic acid and various nutrient elements, described method includes procedure below:
First weigh each component raw material by above proportioning, pulverize and sieve；
(1) first weigh alginic acid raw material, mix with nitrogenous fertilizer stand-by；
(2) weigh after trace element mixes with calcium, magnesium fertilizer, stand-by；
(3) weigh phosphate fertilizer and potash fertilizer, be uniformly mixed, add the mixture that step (2) obtains, mixing, add the mixture that step (1) obtains, then be sufficiently mixed, i.e. obtain this product.
Containing alginic acid and the application of the water soluble fertilizer of various nutrient elements, the water soluble fertilizer containing alginic acid and various nutrient elements can be respectively applied on following crops and plant: flowers, lawn, gardens, nursery stock, tobacco, tealeaves, green pepper, eggplant, cucumber, pumpkin, muskmelon, watermelon, lichee, longan, loquat, banana, grape, cherry, honey peach, peanut, potato, tomato.
Advantages of the present invention with effect is:
1, extract during the marine alga raw material in the present invention comes from the brown alga at deep-sea, the Atlantic Ocean, marine alga active component is high, includes algal polysaccharides, phenols poly-compounds, mannitol, glycine betaine, plant growth regulating substance etc., can improve crop quality, increase stress resistance of plant, improve soil.
2, according to the feature of growth and development of plants, it is provided that multiple nutrients nutrient, wherein containing a great number of elements N, P, K, moderate-element Ca, Mg, trace element Cu, Fe, Mn, Mo, Zn, B, to meet demand of plant growth.
3, all trace elements in addition to B, Mo all use chelated microelements, it is ensured that the crop absorption to trace element, effectively prevent trace element and phosphorus generation antagonism.
4, low-temp low-pressure drying technology (Spay dry technology) is used, it is ensured that in fertilizer, various nutrients mix, it is ensured that Crop is good.
5, had the citric acid of intelligent pH regulatory function by employing, the pH value of regulation fertilizer is 6.5-7, to meet various edaphic condition.
Organic fertilizer of the present invention and inorganic fertilizer combine, and nutrient is complete, instant effect.It is full water soluble fertilizer, is applicable to multiple fertilization mode, wide application.The disease-resistant high-output stress-resistance of alginic acid, growth-promoting root is effective, improves crop quality obvious, and Effect of improving soil is obvious.Fertilizer is with strong points, and formula meets the equilibrium relation between soil, crop, fertilizer, meets the crop each breeding time of the demand to various nutrients.Increase yield significantly, uses this product that fruit can be made to increase production 20-30%, vegetable increase production 25-35%, and flower characteristic is obviously improved.Preparation technology is simple, uses mechanical agitation methods can produce various dedicated fertilizer.
Embodiment 1:
According to the present invention, the weight proportion of the water soluble fertilizer general formulation containing alginic acid and various nutrient elements prepared by each elemental constituent is:
The preparation method of above-mentioned general formulation is as follows:
As a example by 100Kg fertilizer.
1) weigh 3kg alginic acid, then weigh 20.51kg urea, 40.09kg potassium nitrate, be uniformly mixed, stand-by.
2) 0.64kg borax, sodium molybdate, chelated copper, chelated iron, Chelated Manganese, chelated zinc mixture are weighed, stand-by.
3) weigh 2.12kg calcium nitrate and the mixture of 3.13kg epsom salt, be sufficiently mixed uniformly, stand-by.
4) weigh 30.51kg ammonium dihydrogen phosphate, add step 2) and the mixture of step 3), it is sufficiently stirred for, mixes, add step 1) gained mixture.It is sufficiently stirred for, after mixing, gets product.
This example formula fertilizer is applicable to various crop and is in the fertilising of different phase.
