Farmyard manure is the main body of organic fertilizer that is locally produced in the countryside and accumulated on the spot, including excrement, livestock manure and poultry excrement. It is an important material for the development of ecological agriculture. Due to the different characteristics of farmyard manure, reasonable use should be paid attention to during use. The main characteristics of common farmyard fertilizers and the precautions that should be used during use are summarized as follows:
1. Human fecal urine Human fecal urine has high nutrient content, rapid decomposing, and significant fertilizer effect. It is called “fine fertilizerâ€.
Matters needing attention: 1 Before the application of human excrement must be thoroughly decomposed, can be used after detoxification treatment. 2 The chlorine-tolerant plants such as potato, sugar beet, and tobacco are not easy to use, and limited use of saline and alkaline land due to drought and poor drainage. 3 It is prohibited to mix human waste with alkaline substances such as ash and ammonium bicarbonate. 4 Do not dry the human dung and dung, avoid loss of nitrogen.
2, pig manure Pig manure fine texture, complex composition, containing more ammonifying microorganisms, easy to decompose, and the formation of more humus. Pig manure is a soft and stagnant organic fertilizer.
Note: 1 Nitrogen is easy to decompose, phosphorus content is high, and organic phosphorus is not easily fixed by soil. Potassium is mostly water-soluble potassium and is easily absorbed by crops. 2 Phosphorus-containing compounds can be easily converted into phosphoric acid and phosphate under the influence of microorganisms; proteins, urea, amino acids, uric acid, etc. must be converted into ammonium salts and nitrates, which are easily decomposed and lost. 3 When depositing, bedding, commonly used soil or peat, and soil and fertilizer ratio of 3:1 are preferred. 4 Advocate the combination of washers inside the ring and the outside of the stack, and diligently start the pad, which is conducive to the decomposition of manure nutrients. 5 It is forbidden to pour the ash into the circle so as not to cause the loss of nitrogen.
3, cow dung cow dung texture dense, similar composition and pig manure, fecal water content is high, poor ventilation, decomposition is slow, low fermentation temperature, fertilizer effect is slow, it is often called cow dung as "cold fertilizer." The decomposed cow manure is less effective.
Note: 1 cow dung should be added straw, grass, peat or soil gaskets, absorb urine, add horse manure, sheep manure and other hot manure is conducive to promoting cow dung maturing. 2 Add calcium, magnesium and phosphate fertilizers when composting, so as to maintain nitrogen and phosphorus and improve fertilizer quality. At the same time, about 7 cm of mud should be applied to the outer layer of the compost. 3 Decomposing cow dung should be used as a base fertilizer. Must be cooked after application to ensure nutrient transformation and destroy bacteria and eggs. 4 should not be mixed with alkaline fertilizers, such as ammonia, ammonium bicarbonate and so on.
4. Characteristics of chicken manure: 1 Chicken manure has high nutrient content, total nitrogen 1.03, 4.1 times that of cow dung. Total potassium 0.72%, 4.1 times that of cow dung. 2 During the composting process, it is prone to fever, and the nitrogen is volatile: the nitrogen loss of air-dried chicken manure is 8.7, the nitrogen loss of semi-air-dried fermented chicken manure is 37.2, and the chicken manure mass loss is 24.8. Therefore, chicken manure should be stored dry, and then retort before application, and add appropriate amounts of calcium, magnesium, phosphorus fertilizers to play a role in nitrogen. 3 It is suitable for all kinds of soils. It should be used as base fertilizer because of its fast decomposition, and it can also be used as a base fertilizer in combination with other fertilizers. Chicken manure can significantly improve crop quality. 4 Chicken manure has high nutrient content and uric acid, and the fertilizer application is not easy to exceed 30 tons per hectare, otherwise it will cause burning seedlings.
Nuts can generally be divided into two types: one is seeds, such as sunflower seeds, pumpkin seeds, peanuts, etc.; the other is tree nuts, such as pistachios, hazelnuts, cashews, walnuts, pine nuts, walnuts, chestnuts, almonds. And the macadamia and pecans that have been very hot in the past two years. These nut foods contain more protein, calcium and a variety of vitamins, which can provide the body with a variety of nutrients needed by the brain and body.
In general, a nut is a closed fruit classification of a nutrient-covered woody or leathery hard shell. The skin is hard and contains one or more seeds. It includes two types of tree nuts and fruit seeds, walnuts, chestnuts, pistachios, almonds, etc., melon seeds, which belong to the fruit seed class.
