Abstract
The present invention relates to a simple production method of potassium ammonium magnesium phosphate slow-released fertilier for planting melon, fruit, vegetables, tree, flowers and plants. Its composition incldues (by wt%) 15-22% of magnesium oxide, 50-60% of ammonium dihydrogen phosphate and 18-20% of potassium dihydrogen phosphate. Its production method includes the steps of mixing raw material, pulverizing to 60-200 meshes and granulating by means of atomized water.
Description
Technical field
The handy method for producing of the slow released fertilizer containing potassium ammonium magnesium phosphate that a kind of melon and fruit, vegetables, trees, flower planting use in producing.
Background technology
Need fertilizer in melon and fruit, vegetables, trees, the production of flowers and plants process.When melon and fruit, vegetables, trees, flowers are planted in early days and produce, use farm manure, though can satisfy the needs of above-mentioned plant growth to a certain extent, it is a large amount of and to the demand of farm crop fecund to fertilizer to satisfy multi-form agriculture production more.
Multi-form agriculture is produced the instant type chemical fertilizer that use more.Though instant type chemical fertilizer can satisfy crop fecund and the big requirement of demand, but utilization rate of fertilizer is low, and do not have a function of improving melon and fruit, vegetables, flowers self quality, can not satisfy people melon and fruit, vegetables, flowers are being kept on the former feature base, have better color characteristics or have more ornamental demand.Instant type chemical fertilizer life-time service also can make soil compaction, worsens the quality of soil, polluted source.
In the past, the invention of the production method of the full nutrition slow released fertilizer of a kind of ammonium magnesium phosphate potassium was arranged once, the patent No. is 02158897.Can produce the full nutrition slow released fertilizer of a kind of ammonium magnesium phosphate potassium with this method.After melon and fruit, vegetables, trees, flowers crop are used this full nutrition slow released fertilizer, can on color and sight, obtain raising in essence, and the fertilizer efficiency time is long.But the production method process complexity of this slow released fertilizer in the past, the production cycle is long, and time-consuming, effort is unfavorable for reducing cost and improving output.
Summary of the invention
The present invention is a kind of handy method for producing of slow released fertilizer containing potassium ammonium magnesium phosphate, and chemical reaction and granulation of fertilizer can once be finished.The slow released fertilizer containing potassium ammonium magnesium phosphate that uses the present invention to produce is compared with the slow released fertilizer containing potassium ammonium magnesium phosphate of producing with previous method, and fertilizer efficiency equates.Having after not only using to make melon and fruit, vegetables, trees, flowers obtain the raising of essence equally on color and sight, the fertilizer efficiency time is long, can reduce strong points such as the hand labor intensity and the work frequency, its method itself, it is few that production method relatively has more operation, method is easy, and the cycle is short, can lower production cost significantly, improve characteristics such as output, can also be within the limits prescribed, the slow degree of the content decision fertilizer by adjusting magnesium has adaptability widely.
Composition of the present invention is composed as follows:
Magnesium oxide 15-22%
Primary ammonium phosphate 50-60%
Potassium primary phosphate 18-20%
Each composition makes up final proportioning and should be 100% behind the finished product
Production process of the present invention is as follows:
After three kinds of raw material compositions are pressed proportion ingredient in the composition composition; put into mixing device; behind the thorough mixing; put into shredding unit; be crushed to the 60-200 order; raw material after pulverizing is placed on the granulating disc, after 5 ℃-30 ℃ water atomization, is sprayed on the raw material after the pulverizing; start granulating disc in the time of water spray; with the running of the raw material behind water spray granulation, after master batch occurring, row spraying again; after treating that the feed particles surface water is state of saturation; granulating disc is row running granulation again, after the attached powder in feed particles surface is abundant, and row spraying again; and so forth; to the needs particle diameter, after sieving, the particulate state fertilizer that will meet the particle diameter requirement is dried to moisture content under 65 ℃ of-120 ℃ of temperature be to get final product below 5% until granulation.
Potassium primary phosphate was replaced as potassium metaphosphate during composition of the present invention was formed, and other inconvenience also can be made the slow released fertilizer containing potassium ammonium magnesium phosphate with effect same.
Production method of the present invention is easy, efficient, can reduce cost effectively, shortens the production cycle.Compare with the full nutrition slow released fertilizer of ammonium magnesium phosphate potassium with the slow released fertilizer containing potassium ammonium magnesium phosphate that the present invention produces with previous method production; both have the general and function of identical frequency; fertilizer efficiency is 1-2; cleaning, odorless, tasteless; do not hinder root system, insoluble in water loss, free from environmental pollution, can promote root system development, utilization ratio can be up to 98%; salting rate is extremely low, can satisfy the demand of modern agriculture environment protection and raising crop products quality preferably.
The present invention will be further described now to lift an example
Embodiment: with system 4.0mm particle diameter slow released fertilizer containing potassium ammonium magnesium phosphate is example, and composition of the present invention is composed as follows:
Magnesium oxide 20%
Primary ammonium phosphate 60%
Potassium primary phosphate 20%
Production process of the present invention is as follows:
After three kinds of material compositions are pressed proportion ingredient in the composition composition of the present invention; put into the mixing device thorough mixing; put into shredding unit then; be crushed to 100 orders; raw material after pulverizing is placed on the granulating disc; on the raw material of 15 ℃ water after being sprayed on pulverizing after the spraying gun atomizing; granulating disc running granulation; after raw material becomes particle, row spraying again, treat that the feed particles surface water is state of saturation after; granulating disc is row running granulation again; after the attached powder in feed particles surface is abundant, row spraying again, and so forth; until granulation to needs particle diameter 4.0mm; after sieving, do not meet the removal recasting of particle diameter requirement, satisfactory particulate state fertilizer is dried to moisture content less than getting final product below 5% under 100 ℃ of temperature.
Claims (2)
1, the handy method for producing of the slow released fertilizer containing potassium ammonium magnesium phosphate of use during a kind of melon and fruit, vegetables, trees, flower planting are produced, it is characterized in that: composition is composed as follows:
Magnesium oxide 15-22%
Primary ammonium phosphate 50-60%
Potassium primary phosphate 18-20%
