Abstract
The invention belongs to the technical field of a fertilizer, and specifically relates to a water-retention slow-release fertilizer. The water-retention slow-release fertilizer comprises the following raw materials, by weight part, 40-50 parts of a coated slow release fertilizer or a low-solubility slow-release fertilizer, 5-8 parts of a water-retaining agent, 1-2 parts of biological bacteria, 6-12 parts of humic acid, and 6-10 parts of a soil conditioner. The prepared water-retention slow-release fertilizer is low and cheap in cost and convenient to apply, can regulate the water absorbency of the fertilizer according to different conditions, such as crops, soil, and climate, and can be widely applied to grain crops, economic crops and horticultural plants. The fertilizer is long in effective period, the loss due to volatilization and leaching of the fertilizer is greatly reduced, the limited fertilizer and water can be fully absorbed and utilized by plants, thereby achieving the purpose that water and the fertilizer are integrated into one body and the soil is improved. Through application of the water-retention slow-release fertilizer, the cost of farm irrigation can be reduced, and the purpose of efficient water-saving is achieved. The nutrient utilization rate can be greatly increased, and pollution of the fertilizer to crops and environment can be effectively controlled.
Description
Technical field
The invention belongs to technical field of fertilizers, and in particular to a kind of the fertilizer of retaining water and releasing nutrients slowly.
Background technology
Fertilizer be to provide one or more plants necessary to nutrient, improve soil property, a horizontal class material of increasing soil fertility, be one of material base of agricultural production.
Slow release fertilizer, also known as slow-release fertilizer, is class fertilizer new varieties developed in recent years, this kind of fertilizer, can replace the partial function of organic fertilizer, reduces the loss of nutrient in fertilizer, improves fertilizer efficiency, weakens pollution of the fertilizer to soil.Slow release fertilizer mainly includes coated fertilizer and low solubility fertilizer.Coated fertilizer is, for the function or performance that improve fertilizer, to be coated with one layer in its particle surface and have fertilizer made by microporous hydrophobic indissoluble thin film, and using peplos pore size, chemistry or biological decomposition are controlling nutrient releasing speed.Low solubility slow release fertilizer can use plain disk or drum granulating equipment making, and production process low cost, fertilizer price are low, but low solubility slow release fertilizer controlled release properties are poor, and how not ideal enough the slow release effect of fertilizer is.
Water-retaining agent and slow release fertilizer generally mix administration, but water-retaining agent when mixing administration with slow release fertilizer, easily reduces its its swelling capacity, and water-absorbing-retaining ability is reduced.
The content of the invention
The purpose of the present invention is to overcome the shortcomings of that prior art is present, there is provided the fertilizer of retaining water and releasing nutrients slowly of a kind of water conservation and had good sustained release effect.
The purpose of the present invention is achieved through the following technical solutions：A kind of the fertilizer of retaining water and releasing nutrients slowly, it includes the raw material of following weight portion：Coated slow release fertilizer or low solubility slow release fertilizer 40-50 parts, water-retaining agent 5-8 parts, biological bacteria 1-2 part, humic acidss 6-12 parts, soil conditioner 6-10 parts.
Wherein, the coated slow release fertilizer is nitrogen, phosphorus, potassium simple substance, binary or ternary resin coated fertilizers, or containing trace elements iron, manganese, copper, zinc, boron, molybdenum, magnesium, sulfur, the nitrogen of aluminum, phosphorus, potassium simple substance, binary or ternary resin coated fertilizers.
Wherein, the low solubility slow release fertilizer is ureaformaldehyde, urea acetaldehyde or urea isobutylaldehyde.
Wherein, the water-retaining agent is the mixing water-retaining agent of starch-series water-retaining agent and cellulose-based water-retaining agent, the advantage of starch based and cellulose water retention agent is remained simultaneously, stability is high, water absorbing properties are good, the weight ratio of the starch-series water-retaining agent and cellulose-based water-retaining agent is 1：2—1：5.
Wherein, the starch water-retaining agent is starch-grafted acrylonitrile or starch graft acrylamide, and the cellulose water-retaining agent is cellulose graft acrylonitrile or cellulose graft acrylamide.
Wherein, soil conditioner is biomass char.Biomass char surface has very high surface activity, can convey nutrient, is conducive to keeping moisture, a large amount of microorganisms can be allowed to multiply in its surface honeycomb gap for crops, and then improve the fertility in soil, strengthen the yield in soil.Why the present invention adopts biomass char, first is can to keep moisture due to the alveolate texture of biomass char, play a part of water-retaining agent, second is the biological bacteria that the present invention is adopted can be allowed to multiply in a large number due to the alveolate texture of biomass char, the fertility in soil can be improved, plays a part of soil conditioner, the 3rd is the alveolate texture due to biomass char, fertilizer be dissolved in after water can in duct sluggish flow, further function as the effect of slow release.By the size controlling of biomass char in 0.01-0.1cm in the present invention, above-mentioned effect of performance is best.
Specific embodiment
For the ease of the understanding of those skilled in the art, with reference to embodiment, the present invention is described in further detail, but protection scope of the present invention is not limited to following embodiments.
Embodiment 1
The 5 kilograms of addition blenders of biomass char of 70 kilograms of potassium chloride coated slow release fertilizer, 5 kilograms of starch-grafted acrylonitrile water-retaining agent, 10 kilograms of cellulose graft acrylonitrile water-retaining agent, 1 kilogram of EM biological bacteria, 5 kilograms of humic acidss, particle diameter for 0.01cm are stirred, pack, that is, obtain Water-retaining slow-release fertilizer.
With the Water-retaining slow-release fertilizer of the present embodiment, being applied with conventional extended release fertilizer respectively carries out pot experiment, under the conditions of nitrogen, phosphorus, potassium nutrition content are equal, the more conventional slow release fertilizer irrigation times of Water-retaining slow-release fertilizer and irrigation amount are significantly reduced, WUEL improves 55%, and plant recovery of nutrient improves 12 or so；Longer blooming period, pattern are bright-coloured, improve the ornamental value of flowers.
Embodiment 2
The 10 kilograms of addition blenders of biomass char of 75 kilograms of low solubility slow release fertilizer ureaformaldehyde, 4.5 kilograms of starch-grafted acrylonitrile water-retaining agent, 13.5 kilograms of cellulose graft acrylamide water-retaining agent, 1 kilogram of EM biological bacteria, 8 kilograms of humic acidss, particle diameter for 0.05cm are stirred, pack, that is, obtain Water-retaining slow-release fertilizer.
With the Water-retaining slow-release fertilizer of the present embodiment, being applied with conventional extended release fertilizer respectively carries out Brassica campestris L test, under the conditions of nitrogen, phosphorus, potassium nutrition content are equal, the more conventional slow release fertilizer irrigation times of Water-retaining slow-release fertilizer and irrigation amount are significantly reduced, WUEL improves 30%, and plant recovery of nutrient improves 15% or so；Yield of rape improves 25%.
