Different organic fertilizers should be used carefully
The nutrient content and nature of different organic fertilizers vary widely, and the following matters must be taken into consideration when applying them. 1. In addition to direct organic crop straw, organic fertilizers generally require stacking treatment to fully decompose them before they can be applied to the soil. In particular, high-calorie organic fertilizers such as cake fertilizers and chicken manures should pay special attention to this to prevent burning. seedling. 2. Human fecal urine is a fast-acting organic fertilizer with high nitrogen content and is suitable for top-dressing. Before the application, it should be detoxified, and it depends on the crop application. If it is applied too much to the chlorine-tolerant crop, it will lead to a decline in quality. For a long period of time, a single application of human waste must be accompanied by a certain amount of manure, compost, and barley fertilizers that are rich in organic matter to ensure a balanced supply of soil nutrients. 3. Compost, manure, biogas residue, etc. contain a lot of humus, suitable for fertilizing the soil. However, because there are a large number of organic substances that have not yet been completely rotted and decomposed, these fertilizers should be used as base fertilizers and should not be used as top dressings. 4. When straw or mountain grass is used as fertilizer, the first is to apply it in advance; the second is to cut off the application; the third is to use a certain amount of fresh green manure or composted manure to reduce the ratio of carbon to nitrogen and to meet the microbial reproduction Nitrogen needs, and in the early supplement of phosphate fertilizer; Fourth, to be fully mixed with the soil and maintain adequate water supply; Fifth, the amount of soil overturned straw or mountain grass can not be too much, so as not to produce excessive organic acid decomposition Damage to the roots of crops. Sixthly, it is not possible to directly return crop straw or mountain grasses that are seriously or seriously polluted to the field (can be returned to the field after fermentation), so as to avoid the spread of pests or soil contamination. 5. Plant ash contains 5% -10% of potassium oxide, alkaline, can not be mixed with decomposed human urine, manure, or storage, so as not to reduce the effect of fertilizer. 6. Peat, also known as peat or peat, is rich in organic matter and humus, but it has a large acidity, contains high active iron and active aluminum, and has a low degree of decomposition. It is generally not directly used as fertilizer, and is often used as a gasket for basal fertilizer or livestock. material. 7. The humic acid organic fertilizer has a good effect on the thin soil, leafy vegetables, roots, tubers and gramineae, but has poor application effects on rape, cotton and kidney bean.
