Abstract
The invention discloses a nanometer vanadium-selenium sustained and controlled release fertilizer and a preparation method thereof. The nanometer vanadium-selenium sustained and controlled release fertilizer is prepared by mixing the following raw materials, by weight, 20-32 parts of urea, 8-18 parts of diammonium phosphate, 12-22 parts of potassium sulfate, 20-40 parts of humic acid, 0.5-1.5 parts of vanadium pentoxide, 0.5-1.5 parts of sodium selenite, 7-13 parts of a natural polymer nanometer carrier shell and 1-3 parts of a coating agent. The nanometer vanadium-selenium sustained and controlled release fertilizer has the advantages of good controlled and slow release property, high utilization rate, containing of a proper amount of vanadium and selenium, great improvement of the yield and quality of crops, increase of the fertilizer utilization rate by 10-15%, increase of the crop yield by above 10%, effective reduction of the consumption of a chemical fertilizer, reduction of pollution caused by the excessive application of the chemical fertilizer, promotion of the agricultural scientific fertilization, and safe fertilization; and agricultural products produced by using the nanometer vanadium-selenium sustained and controlled release fertilizer have very obvious health functions of cancer prevention, blood sugar reduction, and cardiovascular and cerebrovascular disease prevention.
Description
Technical field
The present invention relates to agricultural fertilizer technical field, particularly a kind of nano V selenium slow-release or control-release fertilizer and preparation method thereof.
Background technology
The year total quantity consumed of China's chemical fertilizer reaches more than 4,100 ten thousand tons (pure nutrients), ranks first in the world; But nutritive ingredient is serious in field loss, and this season utilization ratio is only 35%-40%, than the low 15%-20% of developed country.Agronomic measures improves to improving the utilization ratio of fertilizer, but can't resolve root problem.Scientist's discovery, it is the effective way that improves utilization rate of fertilizer that the slow controlled release of nutrient is put, therefore, the research and development of various sustained-controll-release fertilisers become an important subject of current fertilizer science.
Summary of the invention
The technical problem to be solved in the present invention is: provide that a kind of slow controlled capability is good, utilization rate of fertilizer is high, can significantly improve the nano V selenium slow-release or control-release fertilizer of crop yield and quality.
The technical problem that the present invention will solve another is: the preparation method that a kind of nano V selenium slow-release or control-release fertilizer is provided.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A nano V selenium slow-release or control-release fertilizer, is formed by the preparation of raw material of following weight part:
Described natural polymer nano-carrier shell comprises: a kind of in oligochitosan, starch or two kinds.
The technical scheme one of its optimization is that the preparation of raw material by following weight part forms:
The technical scheme two of its optimization is that the preparation of raw material by following weight part forms:
The technical scheme three of its optimization is that the preparation of raw material by following weight part forms:
A method of preparing nano V selenium slow-release or control-release fertilizer, the steps include:
First, get by weight urea, diammonium phosphate, potassium sulfate, humic acids, Vanadium Pentoxide in FLAKES, Sodium Selenite, natural polymer nano-carrier shell, coating agent, standby respectively;
Secondly, standby Vanadium Pentoxide in FLAKES and Sodium Selenite are stirred, after filtration, obtain Vanadium Pentoxide in FLAKES and Sodium Selenite mixing solutions, through precipitation, obtain Vanadium Pentoxide in FLAKES and Sodium Selenite nano particle again, mix, stir with natural polymer nano-carrier shell again, make the slow controlled release body of nano V selenium, standby;
The 3rd, the slow controlled release body of standby nano V selenium is fully mixed, stirred with urea, diammonium phosphate, potassium sulfate, humic acids, obtain compound;
The 4th, by compound granulation, with coating agent film, screening, cooling, dry, obtain nano V selenium slow-release or control-release fertilizer.
The invention has the beneficial effects as follows:
Nano V selenium slow-release or control-release fertilizer of the present invention, slow controlled capability is good, utilization rate of fertilizer is high, contain appropriate vanadium and selenium, can significantly improve crop yield and quality, can improve utilization rate of fertilizer 10-15%, improve crop yield more than 10%.Promoting the use of of this product, will improve the level of utilizing of agriculture agrochemical greatly, reduces the use of chemical fertilizer, reduces the excessive pollution that chemical fertilizer causes of using, and has promoted the applying fertilizers scientifically of agricultural, safety fertilising.And select interpolation vanadium and selenium, it is micronutrient element, not only based on farm crop, the absorption of vanadium and selenium is produced to vanadium, selenium agricultural-food, also based on vanadium, selenium element, there is the absorption of antagonism farm crop to heavy metal element, produce heavy metal free and pollute the effect of agricultural-food, there is the fairly obvious health-care effects such as anticancer, hypoglycemic, prevention cardiovascular and cerebrovascular diseases.
