Abstract
The invention discloses an anti-coagulation urea formaldehyde slow-release crop fertilizer. The fertilizer is prepared from, by weight, 0.1-0.2 part of potassium ferrocyanide, 35-40 parts of formaldehyde, 57-60 parts of urea, 2-3 parts of microcrystalline cellulose, 1-2 parts of choline chloride, 0.4-1 part of tartaric acid, 0.3-0.5 part of ferrous chloride, 10-14 parts of diatomite in powder, 2-3 parts of polyethylene glycol and 5-9 parts of diammonium hydrogen phosphate. By adding potassium ferrocyanide and the like, the anti-coagulation performance of soil can be effectively improved; by means of the slow-release fertilizer, the content of trace elements can be effectively improved, and the yield and quality of crops are improved.
Description
Technical field
The present invention relates to technical field of fertilizers, more particularly, to a kind of anti-agglomeration ureaformaldehyde slow release Crop fertilizer and its preparation
Method.
Background technology
Ureaformaldehyde slow-release fertilizer is a kind of high-nitrogen slow released fertilizer, and its nutrients release is slow, fertilizer efficiency period length, nitrogen use efficiency are up to 80%
More than, fertilizer efficiency sustainable effect more than 80 days, the longest up to 2 years.Urea potassium aldehyde slow-release fertilizer to drench rate very low, general carbamide,
Ammonium nitrogen is combined the compound fertilizer of fertilizer series, and its fertilizer efficiency rate of drenching in two weeks reaches more than 70%, and urea-formaldehyde fertilizer only drench rate
Have 30%, its rate of release is coincide with plant growth rate;According to the N and P uptake character of crop, make fertilizer nutrient rate of release and work
The need fertilizer speed of thing matches, thus only needing single-dose application just can meet the demand to nutrient for the whole growth cycle of crop, it is to avoid
The man power and material's cost producing because of multiple fertilising, has test to show, with regard to Cotton Gossypii, Semen Tritici aestivi, Herba bromi japonici, Semen setariae, corn and soybean
For the yield of crop this season and absorbing nitrogen amount, therefore how the effect of urea-formaldehyde fertilizer is not so good as ammonium nitrate, carbamide and sulphur ammonium,
Improving ureaformaldehyde is necessary to the suitability of some crops；.
