The way you apply organic fertilizer, is your previous usage correct?

<> basal fertilizer (base fertilizer) is applied.

Basal fertilizer, generally called base fertilizer, is a fertilizer that is applied before sowing or transplanting. When ploughing, the organic manure is evenly applied, and the fertilizer is turned into the soil with the ploughing, this method is simple, easy to operate, can play a good purpose of improving the soil, but in its uniform application to the soil, can not all or even most of the contact with the root system and be utilized by the root system, therefore, the fertilizer utilization rate is bound to cause excess waste, bring certain economic losses, and secondly, it is easy to produce soil obstacles. Therefore, this method is more suitable for planting crops with higher densities.

Top dressing application. There are two methods of topdressing for organic fertilizer: deep soil application and extra-root topdressing. Deep soil application generally applies organic fertilizer near the dense layer of the root system, and covers the soil after application to avoid the loss of nutrient volatilization.

Extra-root topdressing is to mix the compost with 10 times the water evenly, take its supernatant after standing, and spray the fertilizer solution on the foliar surface of the crop with the help of a sprayer for foliar absorption.

It is used as seed fertilizer. There are many ways to use seed fertilizer, such as seed dressing, soaking, strip application, hole application, etc. Seed dressing is a method of dissolving or diluting fertilizer with a small amount of water, spraying on the surface of seeds, and mixing while spraying, so that the fertilizer solution is evenly stained on the surface of the seeds, and sown after drying.

Soaking is to dissolve or dilute the fertilizer solution into a certain concentration of solution, according to the ratio of 1:10 of the liquid seed, put the seeds into the solution and soak for 12 24h, so that the fertilizer solution penetrates into the seed coat with water, and then sows after drying. After ditching or digging holes, fertilizer is applied into the ditch and hole of 3 5cm of the cultivated layer, and then sown near the fertilizer belt, and the distance between the fertilizer is kept above 3cm.

Used as seed fertilizer, fertilizer requires the release of nutrients to be fast, can not be too acidic, too alkaline, the fertilizer itself has no toxic effect on seed germination, and the organic fertilizer that is fully decomposed after composting is a good seed fertilizer.

Used as seedling fertilizer.

Fully decomposed organic fertilizer, evenly released, comprehensive nutrients, is an ideal fertilizer for seedlings. Generally, 10% fermented organic fertilizer with sufficient fermentation is added to a certain amount of peat, fly stone or perlite, and the soil is mixed evenly to make seedling substrate.

Full-layer fertilization and concentrated fertilization of organic fertilizer.

Full-layer application is to sprinkle organic fertilizer all over the surface, and apply organic fertilizer into the whole soil layer through cultivated land, this fertilization method can be applied in the case of more organic fertilizer (4000 6000kg per mu) or crop density. Concentrated application into the soil is to apply compost near the root system of crops by ditching, and this fertilization method is worth using when there is less fertilizer (1500 3000 kg per mu) and soil fertility is relatively low.

Excessive application of organic fertilizer will also cause the same harm as excessive application of chemical fertilizer, which is manifested as difficulty in water absorption of crop roots, easy to burn roots and yellow leaves, stiff seedlings are not long, leaf deformity and other diseases, and the serious consequence is that crops gradually shrink and die. The main factor is the excessive application of organic fertilizer caused by the lack of water in the soil, the imbalance of supply, the accumulation of nitrate ions in the soil, and the nitrate content exceeding the standard, so that the crops are damaged by fertilizer. How to avoid overuse of organic fertilizer, HSBC Agriculture reminds you to control organic fertilizer.

The dosage to be applied, while also paying attention to the following:

1. Strictly abide by the formula proportion. Publicize the scientific and technological knowledge that organic fertilizer is beneficial to the growth of crops, reasonably match farmhouse organic fertilizer with biological fertilizer, mineral fertilizer and chemical fertilizer, and guide fertilization according to the nutritional needs of crops during the growth period.

2. Fully decomposed and fermented before application. Organic fertilizer can activate the soil, improve the soil, enhance the ability of crops to resist diseases, insects and disasters, and improve crop quality and increase yield. However, organic fertilizers such as livestock, human manure and cake meal in nature must be fully decomposed and fermented before application.

After fermentation, the acidity in the organic fertilizer is balanced, the nitrate content is reduced, and the water is supplemented, which is conducive to the combined application of microorganisms and bacteria in the natural soil; Second, after fermentation, it can kill the parasite eggs, pests and bacteria in the raw manure that directly bring the bacteria and harm to the crops and soil.

3. Try to apply the base fertilizer after deep ploughing. To improve the fertilization method, one is to fully mix the organic fertilizer with the soil as much as possible, so as not to spread fertilizer on the surface and reduce the waste of fertilizer and environmental pollution; Second, the base fertilizer at the seedling stage of crops should be applied deeply or early, and the amount of nitrogen fertilizer at the seedling stage should be strictly controlled; Third, it is necessary to fertilize according to the law of crop growth nutrient demand, and generally the crops with a short growth period can be applied as a base fertilizer at one time, such as the cultivation and fertilization of cotton with a long growth period, which should be applied in the early and late stages, that is, "light before and heavy after" to be applied reasonably, in order to achieve the expected target yield effect.

Fourth, with the application of biological organic fertilizer. In real production, the lack of organic matter in the soil is easy to cause crop diseases and low yields. More organic matter fertilizer can not only improve crop yield and quality, but also make crops resistant to drought, premature aging, diseases and pests.

In particular, the combined application of organic fertilizer and biological fertilizer can make the soil have better functions of nitrogen fixation, phosphorus and potassium solution, improve the soil, improve fertilizer utilization rate and save costs, increase yield and increase income.

4. New organic fertilizer.

At present, many manufacturers will produce some organic fertilizers containing organic matter, some advanced technology can be added to nitrogen, phosphorus and potassium and other trace elements, crops and soil are very good, in line with the needs of modern society for organic fertilizer, such as the product biological fertilizer of fertile leaves, which not only contains organic matter, but also contains 18 kinds of nitrogen, phosphorus and potassium trace elements, and also contains 4 kinds of biological flora, is a composite type of green organic fertilizer, which can not only improve the soil, but also loosen the soil and promote the full use of nutrients in the soil。

3. Analysis of the situation of organic fertilizers.

In recent years, the country has paid more and more attention to the fertilizer industry, put the "three rural" issues in the "top priority" of the modernization period, and the country has also advocated more and more safe, green, organic and pollution-free products, and the fertile leaf fungus fertilizer is very in line with the requirements of modern agricultural production because it does not contain hormones

As a very safe product, organic fertilizer is a product that is very in line with the development of the times and the call of society. Israel Vosch Leaf Fertilizer is a green product certified by the EU organic, which has very good feedback on different crops, and has no excessive ingredients such as hormones and heavy metals, which is very safe.

Many modern manufacturers are also learning to produce some organic fertilizers, but some because the technology can not reach, the content of the production can not reach the marked content, or the content reaches the corresponding strain content can not be added, so it is necessary to look at the production standards of organic fertilizer and biological fertilizer, carefully screen the products, find the products of big brand manufacturers, and the quality will be ***!In order to achieve the nutrients required by crops, improve the soil and supplement trace elements.

The benefits of advocating the application of organic fertilizers are as follows:

1) improve the soil, fertilize the soil, after the organic fertilizer is applied to the soil, it can continuously release various nutrients for plants to absorb and utilize through microbial decomposition, and the organic matter can effectively improve the physical and chemical status and biological characteristics of the soil, mature the soil, enhance the fertilizer retention and fertilizer supply capacity and buffering capacity of the soil, and create good soil conditions for the growth of the root system of Hanfu apple.

2) Increase yield and improve qualityOrganic fertilizer is rich in organic matter and various nutrients, including carbohydrates, fiber, amino acids and various sugars and other nutrients. In addition, the decomposed organic fertilizer provides energy and nutrients for soil microbial activities, promotes microbial biological activities, accelerates the decomposition of organic matter, and most of the active substances produced are relatively simple compounds, which are easily absorbed and utilized by Hanfu apples, thereby promoting the growth of the tree and improving the yield and quality of fruits.

3) organic fertilizer contains more nutrients, organic fertilizer nutrients release slowly, fertilizer supply time is long, while fertilizer unit nutrient content is high, less components, fast release. In the production of Hanfu apples, the two should be reasonably coordinated, complement each other, and promote each other, which is conducive to the absorption and utilization of the root system and improves the utilization rate of fertilizer. In addition, the organic acids produced by the decomposition of organic matter in organic fertilizers can also promote the dissolution of mineral nutrients in soil and fertilizers.

The state advocates the use of organic fertilizer, but it does not allow production, we do not allow dry, and organic fertilizer registration cannot be registered at all.

1.Requirements for soil conditions for microbial fertilizers.

Microbial fertilizers are strict on soil conditions. After being applied to the soil, it needs a process of adaptation, growth, and reproduction.

2.Appropriate application time for microbial fertilizers.

Microbial fertilizers should be applied early in the morning and late afternoon or on cloudy days without rain to prevent ultraviolet rays from sunlight from destroying microorganisms.

3.The use of microbial fertilizers should be avoided under high temperature and drought conditions.

The use of microbial fertilizers should be avoided under high temperature and drought conditions, and the changes in temperature and humidity should be paid attention to when applying microbial fertilizers. Under high temperature and drought conditions, the survival and reproduction of microorganisms will be affected, and their functions cannot be fully utilized. It is necessary to combine measures such as soil covering and watering to avoid direct sunlight or difficulty in playing a role due to insufficient moisture of microbial fertilizers.

4.Microbial fertilizers should not be soaked in water for a long time, and should be dry and wet alternately.

Microbial fertilizers should not be soaked in water for a long time, and should be irrigated alternately with dry and wet to promote the activities of biological bacteria. Severe soil drought will affect the growth and reproduction of microorganisms, and the suitable soil moisture content of microbial fertilizer is 50% to 70%.

5.Microbial fertilizers can be used alone or mixed with other fertilizers.

Microbial fertilizers can be applied alone or in combination with other fertilizers. However, microbial fertilizers should not be mixed with uncooked farmyard fertilizers. Mixed with unrotted organic fertilizer, microorganisms will be destroyed by high temperature, affecting fertilizer efficiency.

At the same time, care should be taken to avoid mixing with overly acidic or alkaline fertilizers.

6.Microbial fertilizers should be avoided at the same time as pesticides.

Microbial fertilizers should be avoided with pesticides. Chemical pesticides inhibit the growth and reproduction of microorganisms to varying degrees, and even destroy microorganisms. Do not load microbial fertilizers with tools mixed with pesticides and fungicides.

Microbial fertilizers should not be stored for a long time, and should be applied in time after unpacking. After opening the package, other bacteria may invade, changing the microbial flora and affecting its use effect.

7.Avoid blind application of microbial fertilizers.

Blind application of microbial fertilizers should be avoided. Microbial fertilizers primarily provide a beneficial microbial community rather than mineral nutrients. Microbial fertilizers cannot completely replace chemical fertilizers.

Microbial fertilizers have their applicable soil conditions, crop types, farming methods, application methods and uses, dosages, etc. Only by mastering these technologies can we achieve the effect of increasing production.

8.Pay attention to the factors influencing the effect of microbial fertilizers.

The effect of microbial fertilizer is affected by its own factors, such as the number of effective bacteria in the fertilizer, the size of activity and other quality factors. It is also constrained by other external factors, such as soil moisture, organic matter, pH value, etc.

After three years of using powdered organic fertilizer, bacterial fertilizer and bio-organic fertilizer are all the same, the amount of fertilizer used is related to the crop variety growth cycle yield soil condition and the number of fertilization are related to habits. In a normal year, five tons of powdered organic fertilizer can be applied at a time, and the growth cycle is applied quarterly, and each time the ton is applied, the actual comparison effect can be obtained.

A: From the perspective of the material cycle of agricultural production, the higher the yield of crops, the more nutrients are obtained from the soil, and the nutrients in the soil need to be compensated in the form of fertilization, especially chemical fertilizers. With the increasing amount of chemical fertilizer, the proportion of organic fertilizer in the fertilizer structure is relatively decreasing, and the dependence on chemical fertilizer is increasing for agricultural production.

Under certain conditions, the application of chemical fertilizer does have a great effect on increasing the yield in the current season, but with the gradual increase of the amount of single chemical fertilizer, the consumption of soil organic matter also increases, resulting in the decomposition of soil aggregate structure, the ability to coordinate water, fertilizer, gas and heat decreases, and the performance of soil fertilizer conservation and fertilizer supply becomes poor, and new low-yield fields will appear. Formula fertilization should achieve the two purposes of soil fertilization capacity and soil fertilization at the same time, and it is impossible to rely on chemical fertilizers alone, and organic fertilizers must be added. The role of organic fertilizer, in addition to supplying a variety of nutrients to crops, is more important to renew and accumulate soil organic matter, promote soil microbial activities, help to form soil aggregate structure, coordinate soil water, fertilizer, gas, heat and other fertility factors, enhance soil fertilizer conservation and fertilizer supply capacity, and create conditions for high yield and high quality of crops.

Therefore, formula fertilization is not a simple ratio of several chemical fertilizers, it should be based on organic fertilizer, nitrogen, phosphorus, potassium fertilizer and medium and trace elements, which not only obtains high quality and high yield of crops, but also maintains and improves soil fertility.
