Rational use of organic fertilizer

Organic fertilizers cover a wide range of fertilizers, including almost all fertilizers except chemical fertilizers. They come from a wide range of sources and are quite diverse. According to the same or similar production environment or application conditions of organic fertilizer, similar functional functions and accumulation methods are roughly divided into: manure, compost, straw, green manure, soil fertilizer, microbial fertilizer and so on.

The main advantage of organic fertilizer is that it can provide almost all nutrients and organic nutrients, especially micro-nutrients, to crops. Secondly, it can improve soil, protect the environment and enhance soil microbial activity.

1. Manure , urine , excrement is the excrement of humans and animals. It is rich in organic matter, nutrients required by crops such as nitrogen, phosphorus, potassium, calcium, magnesium, sulfur and iron, as well as organic acids, fats and proteins. Decomposition.

Urea-like fertilizer properties and methods of use:

Name three elements of fertilizer content (%) Nitrogen Phosphorus Potassium use properties human waste 0.5-0.8 0.20-0.40 0.20-0.30 uric acid in the nitrogen-based fertilizer fast decomposition can be absorbed by crops. 1 After application, it is used as base fertilizer, top dressing or diluted 10-20 times for top dressing. 2 contains a small amount of chloride, it is not suitable for large-scale application on the chlorine-free crop .

Pig manure 0.50 0.35 0.40 urinary alkaline, high fat content, balanced, soft, long-lasting, warm fertilizer. 1 After decomposing, apply cold soil and sandy soil and sticky soil to improve the soil.

ã€€ã€€ 2 for seed fertilizer, is conducive to seedling growth, preservation of whole seedlings, strong seedlings.

Cow dung urine 0.40 0.13 0.60 urinary alkaline, fine fecal matter, water content, slow decay, low fermentation humidity, cold fertilizer. 1 used as a base fertilizer after decomposing, applied to cold soaked muddy field is less effective. 2 leafy vegetables mixed with cooked cow dung sowing, the effect is better.

Horse feces and urine 0.70 0.50 0.55 urinary alkaline, loose feces, short fertilizer, hot fertilizer. 1 horse manure contains cellulose-decomposing bacteria, which can be used as composting material to accelerate compost rot. 2 is best used as winter planting vegetable seedling insulation fertilizer.

Sheep feces 0.95 0.35 1.00 urine alkaline, high nutrient content, fast decomposition, hot fertilizer. Accumulate within 1 lap, do not expose to the sun, follow the application with the cover soil. 2 Compost with pig and cow dung, long-term and stable fertilizer.

Chicken manure 1.63 1.54 0.85 The nitrogen in fresh manure is mainly urate, which cannot be directly absorbed by crops, and it is delayed in fertilizer. 1 should not be used freshly, after being decomposed, it can be used as base fertilizer, topdressing and fertilizer. 2 should be stored dry, otherwise high temperature will occur, so that nitrogen will suffer losses.

Duck manure 1.10 1.40 0.62 Goose manure 0.55 0.50 0.95 silkworm manure 2.20-3.60 0.50-0.75 2.40-3.40 II. Stacking manure composting including manure, compost and manure are important organic fertilizer sources in agricultural production in China, and composting nutrients Rich, not only has all the advantages of organic fertilizer, but also the application of heap fertilizer is conducive to environmental protection.

ã€€ã€€ 1. Manure and manure are organic fertilizers that are formed by the combination of livestock excrement and litter. The degree of maturity of manure depends on the nature and nutrient content of the fertilizer. The manure with poor degree of maturity can be used as the base fertilizer. It is not suitable for topdressing and seed fertilizer. The semi-fermented manure is suitable for use as a pre-sowing fertilizer for crops with long growth cycle, completely decomposed. The manure is basically quick-acting and can be used as a top dressing and a seed fertilizer. Compared with the soil, the semi-fermented manure is deeply applied to the sandy soil, and the fully-fertilized manure should be applied to the clay soil.

ã€€ã€€ 2 , composting compost is the use of crop straw, defoliation, weeds, soil, garbage, domestic sewage and human waste, livestock excrement and other organic matter and the right amount of lime mixed and fermented fertilizer. Composting materials have a wide range of sources and good fertilizer efficiency. They are organic fertilizers commonly used in rural areas of China.

ã€€ã€€ 3 , manure and manure are mainly crop residues such as crop stalks, green manure, grass, turf, etc., mixed with garbage, manure, mud, etc., produced under normal temperature and flooding conditions. The organic matter in the piled manure is not easily volatilized under the anaerobic conditions, and the formed quick-acting nutrients are mostly adsorbed by the soil, which is not easy to be lost, and the fertilizer effect is long and stable.

The nature and use of compost fertilizer three elements of fertilizer Name Content (%) Nitrogen Phosphorus Potassium use properties pig manure high organic matter content 0.45 0.19 0.60 long delayed action potential. 1 pig manure soil manure is used as base fertilizer or mashed as seed fertilizer; 2 should be applied to sand and clay to improve soil.

Â Burdock Fertilizer 0.34 0.16 0.40 Sheep Fertilizer 0.83 0.23 0.67 Horse Manure 0.58 0.28 0.53 Soil Manure 0.12-0.58 0.12-0.68 0.26-1.53 â€‹â€‹General Compost 0.40-0.50 0.18-0.20 0.45-0.70 High organic content, good fertilizer efficiency 1 As a base fertilizer; 2 compost is mostly used as fertilizer, seed fertilizer or top dressing.

High temperature compost 1.05-2.0 0.30-0.82 0.47-2.53 garbage compost 0.33-0.36 0.11-0.39 0.17-0.32 turf compost 0.10-0.32 green manure fertilizer 0.21-0.40 0.14-0.16 Third, straw fertilizer straw is a by-product of crops, which contains a considerable amount of nutrient. When the crop is harvested, the straw is directly returned to the soil, which has the effect of improving soil physical, chemical and biological properties, improving soil fertility and increasing crop yield. The source of straw is extensive and the quantity is huge. According to statistics, the nutrients provided by crop straw account for about 13%-19% of the total nutrients of organic fertilizer in China.

Straw fertilizer nutrient and use method Fertilizer name three elements content (%) Nature use method NPK corn stalk 0.61 0.27 2.28 Rice straw, wheat stalk, corn stalk is thicker, more fiber, rot decomposition slow, and green manure, beans The stems and the like decay faster, the back strength is long, the fertilizer can be fertilized, and the soil is loosened. 1 The corn pole can be cut into the pad column, and the manure can be applied; 2 the green manure and the bean stick can be turned over as the base fertilizer or the piled decomposed and applied; 3 the straw returning field should be applied with the appropriate amount of fertilizer synergist and quick-acting nitrogen fertilizer To accelerate decay.

Rice straw 0.63 0.11 0.85 wheat rod 0.48 0.11 0.62 soybean rod 1.30 0.30 0.50 peanut vine 1.62 0.25 0.74 mung bean rod 1.30 0.60 2.40 four, green fertilizer Where the green part of the plant is ploughed into the soil as a fertilizer, called green manure. Green manure is divided into wild and cultivated. The following mainly introduces the cultivation of green manure. The cultivated green manure is mainly leguminous crops, among which are Chinese milk vetch, broad beans, soybeans, and peas. These plants have root nodules, which can fix atmospheric nitrogen for growth and utilization. The roots have strong absorption capacity for other nutrients and grow fast. The green fertilizer is quickly decomposed after being ploughed into the soil, which is an excellent source of fertilizer and can also cause good soil. There are many varieties of green manure, and it has strong adaptability. Various soils can be planted and applied. Green manure is a good composting material. It is also often used as a base fertilizer to be pressed into the soil 2 weeks before sowing or planting. It is put on hold, flooded with water and added with fertilizer synergist to neutralize the organic acid produced during the decomposition of green manure.

Nutrients and methods of use of green manure The three elements of fertilizer name (%) Nature of use NPK Zinc 3.12 0.72 3.40 Nitrogen rich in fresh and juicy decomposition is easy but the fat is short. 1 Cut green manure 10-15 days before planting, turn into soil and smash, as base fertilizer scorpion 3.18 0.87 1.62 yellow bud 3.23 0.81 2.38 pea 2.76 0.82 2.81 2 chopped fresh stems and leaves, can be used as base fertilizer after stacking.

Broad bean 2.75 0.60 2.25 oil tea 2.52 1.53 2.51 Tianjing 2.20 0.58 0.72 Rich in nitrogen, stems and leaves are coarse and hard, applied to dry land, less water. Therefore, the decomposition of decay is slower, but the longer the stamina is the dry land, the good green manure of the paddy field. 1 Mainly used as base fertilizer, it can also be used as top dressing after rot and rot; 2 mashed fresh stems and leaves are directly applied to the bottom of the raft at 20-30 cm for base fertilizer; 3 smashed and applied after farmer's fertilizer stacking.

Ramie 1.87 0.45 1.26 Mung Bean 2.08 0.52 3.90 Amorpha sinensis 3.02 0.68 1.81 V. Mixed soil and fertilizer is a traditional farmyard fertilizer in China. It has a wide range of sources and various types. It mainly contains loam, mud, ash, and slaughter waste. Wait.

1. Fertile soil refers to argillaceous soil such as smoky soil, bauxite and nitrate soil. The fat soil is slightly alkaline, and it is a quick-acting and hot fertilizer. It should be used as a base fertilizer or heat preservation fertilizer in winter.

2, mud and mud is a surface of fine soil, inorganic salts, organic matter and other sediments deposited in the ditch, lake, river, pond, sea bottom and aquatic animals and their excrement together with decomposition and fusion of fertilizer and sludge. The degree of decomposition of mud fertilizer is poor. It is a slow-acting fertilizer. It can be directly applied to the soil. It can be used as a base fertilizer or top dressing. It can also be used as a material for tanning grass pond mud.
