Abstract
The invention discloses two production methods of a water-retentive biodegradable fertilizer produced with a water-absorbing degradable material. The water-absorbing degradable material is konjak, starch, carboxymethyl cellulose or chitosan. One method comprises the following steps: mixing a chemical fertilizer with the water-absorbing degradable material according to the weight ratio of 20: (1-5), the chemical fertilizer being nitrogen fertilizer, phosphate fertilizer or potash fertilizer, adding water into the mixture, then drying, cutting, sterilizing and subpackaging the mixture to obtain the water-retentive biodegradable fertilizer. The other method comprises the following steps: firstly utilizing the water-absorbing degradable material to filter a body of water by multistage, purifying the eutrophic body of water, after the quality of the body of water is qualified, precipitating, drying, sterilizing and subpackaging the water-absorbing degradable material to obtain the water-retentive biodegradable fertilizer. On one hand, the water-retentive biodegradable fertilizer is provided from the aspect of improving the biodegradability, and on the other hand, the eutrophic body of water is processed in advance to obtain the water-retentive material rich in nitrogen, phosphorus and sulfur, so as to reduce the discharge of nitrogen, phosphorus and sulfur.
Description
Technical field
The present invention relates to the water conservation chemical fertilizer, refer to that particularly a kind of production possesses the method for water conservation and biodegradable fertilizer.
Background technology
China's water resources is generally nervous, and arid, semiarid area is larger, even if partial area whole years be not the arid area, but also the big area arid may occur at certain special time period, and then affect the farm crop harvest.
Existing arid water-retaining method is main or take drought-relief measures according to arid situation itself, Ru Yunshui, irrigation etc., and the other technical material water-retaining capacity that lays particular emphasis on of water-keeping material, and the biological degradability of material is often not good.On the other hand, these biological important nutrient of nitrogen phosphorus sulphur are superfluous in the water pollutant, thus so that body eutrophication.Had in the prior art scientific and technical personnel in a large number the plant growing of absorbed nitrogen phosphorus sulphur on water body, thereby reach the purpose of processing body eutrophication.This method no doubt can reach the effect that purifying water body adds natural beauty, if but rich nutritive material discharging excessive (increase of the enlarging of water body periphery factory and increase, water body periphery population and the increasing of water body periphery discharging intensity etc. can cause that the rich nutritive material discharging is excessive), then the practice of this water surface planting plants landscape is often slow in reacting, can not fundamentally solve the problem of body eutrophication fully.
Summary of the invention
Purpose of the present invention will overcome the existing deficiency of prior art exactly, and a kind of possess water conservation and biodegradable chemical fertilizer are provided.
The invention provides a kind of method of utilizing the production of degradable water-absorbing material to possess water conservation and biodegradable fertilizer, it is characterized in that: after first chemical fertilizer and degradable water-absorbing material being mixed according to weight ratio 20:1 ~ 5, add that water mixes, dries, cuts, sterilization, packing namely gets possesses water conservation and biodegradable fertilizer, described degradable water-absorbing material is konjaku, starch, carboxymethyl cellulose or chitosan, and described chemical fertilizer is nitrogenous fertilizer, phosphate fertilizer or potash fertilizer.
The present invention mixes the degradable water-absorbing material with chemical fertilizer, but obtain water conservation and continue the slowly fertilizer of release chemical fertilizer effective constituent, be used in the farmland of possibility drought, can play the effect of slowly supplying water to crop at arid time water conservation, thereby play the effect of protecting grain growth.
The present invention also provides a kind of and has utilized degradable water-absorbing material purifying eutrophication water body and produce the method that possesses water conservation and biodegradable fertilizer, it is characterized in that: use first the degradable water-absorbing material to the water body cascade filtration, purifying eutrophication water body, after Water quality is up to standard with degradable water-absorbing material precipitation, oven dry, the sterilization packing namely gets possesses water conservation and biodegradable fertilizer, described degradable water-absorbing material is konjaku, starch, carboxymethyl cellulose or chitosan.
Containing the organic more water such as ammonia nitrogen, phosphorus in view of a lot of waste water are actually, is waste water outwardly, is actually the chemical fertilizer that can be used as a lot of plant-growths.The present invention just in time can utilize the strong characteristics of water conservation chemical fertilizer water-retaining capacity, absorption contains the organic more water such as ammonia nitrogen, phosphorus, whole as fertilizer sources applies fertilizer to plant after the oven dry, reaches the effect of processing or partially disposed organic waste water, alleviates the problem of the water pollution that becomes increasingly conspicuous.
Beneficial effect of the present invention is: one aspect of the present invention provides from raising biodegradability angle possesses water conservation and biodegradable chemical fertilizer, on the other hand eutrophication water is processed in advance, thereby the water-keeping material that obtains rich Nitrogen-and Phosphorus-containing sulphur serves as fertilizer, also reaches the purpose that reduces nitrogen phosphorus sulphur emissions.
Superfluous to these biological important nutrient of nitrogen phosphorus sulphur in the solution water pollutant, thus body eutrophication reduced.Technology is simple, and low price is easy to promote, and can be used for plant water keeping, is adapted at arid most, and use the semiarid zone, and winter wheat is survived the winter to play a protective role.To the agriculture production water conservation, safeguard soil moisture content, reduce body eutrophication significant.
