How to improve the efficiency of farmyard manure Why sometimes the effect of farmyard manure is not good?

"The dung is the strength, the water is the life", "the seventy-two rows of farmers are the first, and the one-acre garden is the first." In recent years, the application of farmyard manure and organic fertilizer in orchards has received more and more attention. There are many kinds of farmyard manure and the source is large and the quantity is large, which is convenient for local materials. Organic fertilizers are characterized by a comprehensive range of nutrients and a suitable ratio. They contain not only nitrogen, phosphorus and potassium, but also calcium, magnesium, sulfur, iron and some trace elements.

These nutrients are mostly in the state of organic matter, and must undergo chemical and physical action in the soil and fermentation and decomposition of microorganisms to gradually release nutrients, so that the fertilizer effect is long and stable. In addition, the application of organic fertilizer is conducive to the formation of soil aggregate structure, the ratio of air and water in the soil is coordinated, the soil is loose, and the ability to retain water, heat, ventilate and protect fertilizer is increased.

Farmyard manure must be fermented before application

1. Cold dung fruit wood hot dung vegetables, raw manure on the ground and rotten. "There will be many problems after using the unfertilized farmyard manure.
2. Unfertilized farmyard manure often contains a large number of pathogens, which can easily cause pests and diseases of fruit trees, and also pollute the environment;
3. The unfertilized farmyard manure nutrient is mostly organic, and it is not easy to absorb the fruit trees, which will cause the fertilizer to be lost;
4. When the farmer's fertilizer is decomposed and fermented by microorganisms in the soil, it will generate a lot of heat and easily burn the capillary roots of the fruit trees;
5. When the farmer's fertilizer is decomposed and fermented by microorganisms in the soil, it will absorb a large amount of nitrogen, causing short-term nitrogen deficiency in the fruit trees;
6. The process of microbial decomposition and fermentation in the soil requires a process that causes the fertilizer to lag behind, which is difficult to be consistent with the growth rhythm of the fruit trees and the period of fertilizer requirement, and can not achieve the purpose of fertilization or even cause adverse effects. Therefore, farmyard manure must be fermented before it can be applied.

Farmhouse fertilizer decomposing technology

Fertilizers formed by mixing various fresh livestock excrement and gasket materials need to be decomposed into nutrients and humic substances in the state of crop availability through the action of microorganisms during the accumulation process. Such organic fertilizer is suitable for application, and the key to heap rot is timely. There are four methods for composting organic fertilizer.

1. Loose pile method

The fresh livestock excrement in the circle is loosely piled up in the accumulating site, and the ventilation is maintained well during the accumulation process. Under high temperature conditions, livestock manure and broiler decompose quickly, and in a short period of time, decomposed organic fertilizer can be produced, but nitrogen and other nutrient losses are large.

2, close packing method

The livestock excrement from the circle is piled up layer by layer on the composting site, and is compacted while being stacked. If it is too dry, add appropriate amount of water to keep it moist. The height of the pile is 1.5m to 2m. After the pile is completed, the pile is sealed with soil, and the temperature is generally maintained at 15 °C to 35 °C. In this way, the accumulation of humus is more and the loss of nitrogen is less. After about 3 to 4 months, the organic fertilizer can reach the semi-decomposed state, and it can be completely decomposed for more than 6 months.

3. Loose and tight cross-stacking method

The use of loose and close alternating stacking can shorten the maturity time of organic fertilizer and reduce nitrogen loss. The fresh organic fertilizer is loosely piled up about one meter high outside the circle, and is not compacted for fermentation.

Generally, after 2 days to 3 days, the temperature in the pile can reach 60 ° C to 70 ° C, and then the fresh organic fertilizer can continue to be piled up, so as to pile up layer by layer until the height is 2 meters to 2.5 meters. Seal the pile with soil, keep the temperature, hinder the air from entering, and prevent the loss of fertilizer and the evaporation of water. Generally, it can reach a semi-humic state in one and a half months to two months, and it can be completely decomposed after 4 months.

Mixing fertilizer with farmyard manure can play a lot of good effects.

1. The nutrients needed for crop growth can be fully supplied. The characteristics of chemical fertilizers are high nutrient content, fast fertilizer efficiency and short duration, and relatively simple nutrients; agricultural organic fertilizers are mostly complete fertilizers, but the nutrient content is low, the fertilizer efficiency is slow and the duration is long. Therefore, the combination of chemical fertilizer and agricultural organic fertilizer can be used to complement each other.
2. Can reduce nutrient fixation and improve fertilizer efficiency. After the fertilizer is applied to the soil, some nutrients are absorbed or fixed by the soil, which reduces the effectiveness of the nutrients. If mixed with farmyard manure, it can reduce the contact surface between fertilizer and soil, thus reducing the chance of being fixed by the soil.
3. It can save, reduce loss and improve the nutrient absorption conditions of crops. Fertilizer has a high solubility and causes high osmotic pressure on the soil after application, which affects the absorption of nutrients and water by crops, which increases the chance of nutrient loss. If mixed with farmyard manure, this drawback can be avoided.
4. It can regulate soil acidity and alkalinity and improve soil structure. Farmyard manure is a raw material for microbial life. Fertilizers supply inorganic nutrients for the growth and development of microorganisms. When mixed, they can promote the activities of microorganisms and promote the decomposition of organic fertilizers.

How to improve the fertilizer efficiency of farmyard manure

Although farmyard manure has the advantages of rich nutrient content and loose soil, it also has the disadvantages of low effective content and slow fertilizer efficiency. How can we improve the short-term and improve the fertilizer efficiency of farmyard manure? Practice has proved that the proper blending of chemical fertilizers in farmyard manure can not only effectively prevent the loss of fertilizer efficiency, but also increase the fertilizer efficiency.

The specific practices are as follows:

1. Adding ferrous sulfate to human excrement and adding 500-600 g of ferrous sulfate per 100 kg of human excrement can convert ammonium carbonate in human excrement into ammonium sulfate with stable nature, thus effectively inhibiting human excrement Nitrogen loss.
2. Adding superphosphate to human excrement and adding 5 kg of superphosphate in 100 kg of human excrement, stirring it evenly and storing it for 3 to 5 days, can convert ammonium sulfate, which is extremely volatile and lost in human excrement, into stable phosphate. Ammonium, phosphorus and nitrogen.
3. Adding superphosphate to the ring fertilizer, adding 2% of the superphosphate in the circle fertilizer, fully stirring and then storing it for about 20 days, it becomes a high-quality organic fertilizer, and the fertilizer effect can be more than doubled.
4. Adding bicarbonate to the manure and adding the raw materials such as crushed plant straw and soil (or firewood bottom), adding 1% ammonium bicarbonate to mix, pile up the pile, seal the pile with mud, and become high quality and efficient after decomposing. Biological potash.
5. Add calcium superphosphate to the ash, soak the grass ash 3 kg to 15 kg of water, add 1 kg of superphosphate, stir evenly, add 50 kg of water after 6 hours, mix well, wait for the static precipitation, take the clear spray, get The same fertilizer effect of potassium dihydrogen phosphate solution

Steroids

"Steroids are a general term for a large group of derivatives widely distributed in the biological world, which can also be called steroidal or steroidal compounds. Steroid hormones are mainly synthesized and secreted by various parts of the body, and a small part can be synthesized artificially. They play an important auxiliary role in the functional activities of organs, tissues and cells of the body. Steroid hormones mainly include adrenal cortical hormones secreted by the adrenal cortex and gonadal secretion of sex hormones, when taking a large number of steroid hormones, will produce swollen face, nausea and other side effects
