Description
Technical Field
The invention relates to the technical field of fertilization, in particular to a biochemical fertilization method for soil.
Background
Fertilization is an agricultural technique in which a fertilizer is applied to soil or sprayed on crops to provide nutrients required by the crops and to maintain and improve soil fertility. The main purposes of fertilization are to increase crop yield, improve crop quality, fertilize soil and improve economic benefits, so that rational and scientific fertilization is one of the main means for ensuring crop safety and maintaining sustainable development of agriculture.
At present, the main basis of fertilization is soil fertility level, crop type, target yield, climate environment and fertilizer characteristics, so that a proper fertilizer is selected, the required fertilizer dosage is estimated, and fertilization time and fertilization mode are determined; wherein, the soil fertility level mainly comprises soil clay particles, soil organic matters, soil acidity and the like, and the fertilization regulation measures mainly comprise applying organic fertilizers to increase soil nutrients and improve soil structure, and adding physiological active substances to stimulate crop growth and enhance disease resistance and the like. However, the existing soil fertility level evaluation system and fertilization regulation and control measures are extensive, and the yield increasing effect of the fertilizer cannot be fully exerted.
In view of the above, the present invention is particularly proposed.

The soil nutrient analysis and fertilization regulation are as follows:
1) the soil salinity content of this experiment institute is lower, does not have the problem of soil salinization basically, and each sampling point and parallel appearance difference are very little, can fully explain the problem of salinity content, and the salinity average value is 0.018% +/-0.01%. The mango trees have no strict requirements on soil salinity, the mango roots are mainly distributed in a soil layer of 30-40cm, roots of the soil layer of 0-20cm are few, and the mango roots are greatly interfered by human factors in surface soil of a city, so that the relationship between the damage degree of the mangoes and the salt content of the surface soil is very small. The mango tree soil is slightly salinized, and the mango planting is not affected, so that the salt content of the soil does not need to be adjusted.
2) The water content of the soil researched by the experiment is low, the difference between each sampling point and the parallel sample is small, the average value of the water content is 1.13% +/-0.09%, and the water content of the mangoes forest soil is extremely low according to data analysis, so that the irrigation method needs to be improved. In the production management of an orchard, water-saving irrigation and water resource rationalization management become the primary tasks of sustainable development of the mango industry at present and in the future. The water is an important factor influencing the conversion of soil nutrients, a proper amount of water can be beneficial to the decomposition and absorption of nutrients in soil and fertilizers, and the transitional irrigation not only can cause water resource waste, but also can cause fertilizer loss and bring hidden danger to environmental pollution.
3) The pH value of the soil researched by the experiment is slightly alkaline, the average value of the pH value is 8.06 +/-0.10, the difference between each sampling point and the parallel sample is small, and the pH value of the soil can be well reflected. The research shows that: the mango is suitable for growing in weakly acidic to neutral soil, and the pH value level of the suitable soil is 5.5-7.5; when the pH value of the soil is lower than 5.5, the acidity of the soil is too high, so that the nutrient effectiveness of the soil is reduced, heavy metal ions such as aluminum ions and manganese ions are activated to produce a toxic effect on plants, and the concentration of arsenic ions in mango pulp reaches the upper safety warning value limit (50 mug/kg); when the soil is in an alkaline state, the concentration of salt-based ions in the soil is greatly increased, and the mango can be subjected to sodium toxicity and iron deficiency and green loss. In conclusion, the pH value of the soil is higher, so that the phosphogypsum can be properly applied to ensure that the pH value level of the soil reaches 5.5-7.5, the content of active calcium cations in the soil is improved, the harm of sodium carbonate and sodium bicarbonate to crops is reduced, and the pH value is reduced. In addition, organic materials can be applied, which reduce the ph of the soil over time, such as pine needles, compost or compost, which however only occurs in soils grown for a long period of time and requires a long time, generally more than a year, and which also contribute to improving the air permeability and drainage of the soil, which is best suited for the growing of small plots due to limitations in the amount of organic matter required and the time required to decompose into usable soil.
4) The content of organic matters in the soil researched by the experiment is higher and basically in a very high level in the classification standard, wherein the content of the organic matters in the second point location and the ninth point location is slightly lower, the content of the organic matters is different from the content of the other point locations, the content of the organic matters in the soil can be really reflected basically, and the average value of the organic matters is 5.35 +/-0.71%. From the principle of soil genesis, soil organic matters are the basis for forming soil physicochemical properties, are links connecting biological elements and soil generation and evolution in the soil formation process, regulate the amount and structure of solid, liquid and gas phases of the soil and influence each process of soil ecological function. The long-term application of organic fertilizers can activate soil nutrients, improve the soil nutrient content and enhance the soil fertilizer supply capability, and organic and inorganic compound fertilization is one of the methods for improving the organic matter content. The research shows that: the organic matter content of the soil after the organic and inorganic fertilizers are applied in combination for 5 years is obviously higher than that of the soil after the single fertilizer application, and the amplification is 18.5 percent. The mode has the characteristics of high efficiency, high fertilizer efficiency and the like.
5) In the contents of nitrogen, phosphorus and potassium in soil researched by the experiment, the average value of ammonium nitrogen is 4.73 +/-0.72 mg/kg, the average value of quick-acting phosphorus is 18.25 +/-1.05 mg/kg, and the average value of effective potassium is 144.26 +/-6.26 mg/kg. The ammonium nitrogen content is low, and the differences between all sampling points and between parallel samples are small. The effective potassium content is mostly at the middle upper level, the content of the sample No. six is at the extremely high level, and the effective potassium content of the soil is at the middle upper level in general. The total content of the available phosphorus is at the middle-upper level, and the difference between sampling points and between parallel samples is small. Nitrogen, phosphorus and potassium are essential nutrient elements of plants, are important material bases of soil fertility, and are different from each other due to the influence of soil phosphorus and potassium nutrition and human activities on the weathering degree of the matrix of the adult soil and different migration and deposition of the elements. The dry land is affected by cultivation, physical and chemical weathering of the parent soil is deepened, minerals containing phosphorus and potassium are decomposed, and the content of phosphorus and potassium in the soil is increased. Therefore, the contents of phosphorus and potassium in the soil researched by the experiment are relatively high, and the soil is rich in nutrient components. The green manure is one of the traditional important organic fertilizers in China, and part or all of green plants are directly turned and pressed into soil to serve as the fertilizer. The green manure contains rich nutrients such as nitrogen, phosphorus, potassium and various trace elements and a certain amount of organic matters, and has the advantages of quick decomposition, high fertilizer efficiency and good soil improvement and fertility improvement effects.
6) The average value of the effective sulfur content of the soil researched by the experiment is 3.21 +/-0.26 mg/kg, the difference between each sampling point and between parallel samples is small, the variation coefficient is small, the effective sulfur content of the soil can be truly reflected, and the effective sulfur content of the soil is extremely low. Sulfur is a necessary nutrient element for plant growth, cannot be replaced by other nutrients, plays an important role in physiological processes of carbohydrate metabolism, photosynthesis, respiration and the like of plants, plays a certain role in processes of detoxification, growth regulation and the like of the plants, and can affect the structures and components of certain substances in the body, thereby affecting the quality and yield of crops. The application of the sulfur fertilizer can cause the pH value in the soil to be reduced, the pH value reduction can promote the sulfur conversion, absorption and transportation in the soil and improve the effectiveness of trace elements in the soil, and the effective sulfur in the soil is a main source of sulfur elements in plants. Aiming at the soil researched by the experiment, the effective sulfur content in the soil can be increased by properly using the sulfur fertilizer, and the effect of reducing the pH value is achieved.

The difference between each parallel sample is large, and the coefficient of variation is large. Wherein the bacteria at the nine-point site are fewer in number, the fungi at the first and second-point sites are fewer in number, and the soil fertility is higher than that of the other sampling pointsLow.
