Description
Technical field：
The invention belongs to technical field of agricultural fertilizers, it is related to water-retention fertilizer and rich phosphorus potash fertilizer in a kind of agricultural, more particularly to
Rich phosphorus potassium water-preserving nutritive fertilizer of a kind of bone meal and humic acid potassium base intercrossed network type and preparation method thereof.
Background technology：
For fertilizer angle, nitrogen, phosphorus, potassium are three big nutritional factors of plant growth.Wherein, phosphorus is a variety of in plant
The important composition element of compound such as protein, nucleic acid and enzyme etc..In addition, phosphorus energy Accelerate bloom, improves many water fruits and vegetables
Quality, additionally aids the disease resistance and drought-resistant ability of enhancing plant.Conversely, when phosphate fertilizer is insufficient, plant growth will be by
Suppress, it is slow to bloom, flower is faint in color, the fragrance of a flower is not enough, or even wither come off in advance.It is most vigorous that potassium is typically distributed on plant strain growth
Position, and absorption and utilization of the plant to nitrogen can be improved, promote it to be converted into protein.Meanwhile, potassium can also promote flowers with
The photosynthesis of vegetables and fruits, makes plant healthy and strong upright, makes pattern gorgeous, is difficult lodging, and strengthen the crop mouthful of fruit and greengrocery
Sense.Conversely, plant potassium deficiency, grow it is short, cane fruit with it is carefully thin, branches and leaves are weak, and seed and fruit are small and shrivelled.Therefore, phosphorus,
Potassium is even more important to flowers with vegetables and fruits class plant, especially in florescence, often needs using sufficient phosphorus potash fertilizer.At present, in the market
Rich phosphorus potash fertilizer, mainly potassium dihydrogen phosphate, the inorganic fertilizer such as calcium superphosphate, and this kind of fertilizer is used for a long time easily causes soil
It is hardened, the nutrient of soil is lacked of proper care, be unfavorable for guarantor's entropy of soil.
Drought and water shortage is the important problem that the whole world faces, and China is especially prominent, it was reported that water resource is only generation per capita for China
1/4 (north is 1/20) of boundary's average level, this makes us to respond actively the challenge of water resources crisis.For the problem,
It is a kind of preferably solution using water-loss reducer.Water-loss reducer, also known as high hydroscopic resin, are a kind of new function macromolecule materials
Material.Agriculturally, it can largely absorb water and in gel, and will absorb water in dry condition and point slowly to discharge, and have
Unique water absorbing capacity and water holding capacity；There is extensive meaning in terms of crop keeps a full stand of seedings volume increase, afforestation, control of desert
Justice.But, in the market water-loss reducer function is single, and only with water-absorbing-retaining feature, this limits guarantor to a certain extent
The application space of aqua.Therefore, Multifunctional protective aqua is studied, and realizes " water-absorbing-retaining " and " the fertilizer conservation guarantor of water-loss reducer simultaneously
Moisture in the soil ", such as exploitation water suction protect entropy, rich phosphorus potassium type multi-functional water conservation organic fertilizer to the agricultural industry of China, especially flowers with
Vegetables and fruits industry, it is significant, it is the key areas of current fertilizer innovation.
Possesses water retaining function at the same time with the technology of preparing of the compound fertilizer of rich phosphorus potassium function, currently mainly there is absorption work
Skill type, blending craft type, coating process type etc..Wherein water-loss reducer, is exactly immersed in the solution of phosphorus potassium nutrition by absorbent-type, etc.
Drying can be prepared by adsorptivity the fertilizer of retaining water and releasing nutrients slowly after Nutrient absorption balance.But though this kind of technique prepares simple, nutrient density
It is relatively low, also do not possess the function of " preserving soil moisture ".And hybrid technique, it is by physical mixed by water-loss reducer and phosphorus, potassic fertilizer
Hybrid particles are made, but this kind of fertilizer easily blends inequality, and water absorption is relatively low；And coating process refers to, pass through physics
Or chemical mode parcel is to the technique of fertilizer surface, but this kind of fertilizer water absorption is low, it is also desirable to specific coating equipment, cost
It is higher.Synthesis technique, refers to make fertilizer nutrient by being chemically bound on water conservation macromolecular scaffold by chemical reaction, this side
Formula can effectively improve nutrient content, improve slow release effect.However, in product prepared by current synthesis technique, have simultaneously
There is not been reported for the fertilizer of standby " rich phosphorus potassium, water suction, soil moisture conservation ".
The content of the invention：
It is an object of the invention to provide a kind of bone meal of rich phosphorus potassium and humic acid potassium base intercrossed network type water-preserving nutritive fertilizer, together
When possess the function of " rich phosphorus potassium, water suction, soil moisture conservation ".
To achieve the above object, technical solution of the present invention is：With bone meal, humic acid potassium, acrylic acid,
