Abstract
The invention discloses a controlled-release urea fertilizer and a preparation method thereof. The controlled-release urea fertilizer is prepared from the following raw materials in parts by weight: 30-35 parts of urea, 20-25 parts of borax, 5-6 parts of boric acid, 2-4 parts of manganese sulfate, 1-2 parts of ammonium molybdate, 1-2 parts of sodium sulfate, 15-20 parts of calcium carbonate, 8-12 parts of kaolin, 7-8 parts of actinolite powder, 2-3 parts of sodium sulfite, 10-12 parts of brown sugar, 2-3 parts of hupeh anemone herbs, 1-3 parts of passiflora wilsonii hemsl., 8-10 parts of swamp mahogany leaves, 7-8 parts of sophora japonica roots, 3-4 parts of huon pine, 1-2 parts of phyla nodiflora, 1-2 parts of all-grass of arcuaate iolet and 1-2 parts of roots of useful viburnum. The controlled-release urea fertilizer contains the Chinese herbal medicines including hupeh anemone herbs, passiflora wilsonii hemsl., swamp mahogany leaves, sophora japonica roots, huon pine, phyla nodiflora, all-grass of arcuaate iolet and roots of useful viburnum, so that the consumption of pesticides for crops and the controlled pests can be reduced; urea is combined with calcium carbonate, kaolin and actinolite powder, so that the release speed of the fertilizer is reduced, and a controlled release effect is taken; the direct contact between soil and the fertilizer can be isolated, the nutrient release of urea can be controlled, the soil can be improved, and the soil can not be polluted.
Description
Technical field
The invention belongs to compound manure technical field, relate in particular to a kind of slow-release carbamide fertilizer and preparation method thereof.
Background technology
Fertilizer, be to provide the essential nutritive element of one or more plants, improve soil property, one class material of the level of increasing soil fertility, one of basic substance of agriculture production, fertilizer type is a lot, there is nitrogen, phosphorus, the chemical fertilizer such as potassium, there is dregs of beans, animal excrement, the organic fertilizer such as agricultural wastes, also have the bio-feritlizers such as biological bacteria, also has silicon, magnesium, iron, boron, the secondary and micro-element fertilizers such as selenium, Different Crop is due to different habits, different growth phases, all not identical to the demand of fertilizer, therefore, need to be in conjunction with different crop varieties, study different fertilizer, be starved of, to improve quality and the speed of growth of crop, increasing corps nutrient is worth with health care, promote human health, to promote the well-being of mankind.
Summary of the invention
