How to choose microbial fertilizer for planting pollution-free crops?

Microbial fertilizer refers to the preparation of active microorganisms produced by the cultivation of specific microbial strains.How to choose microbial fertilizer for planting pollution-free crops?Let me introduce you.

How to choose microbial fertilizer for planting pollution-free crops

Microbial fertilizer is nontoxic, harmless and does not pollute the environment. Through the vital energy of certain microorganisms, it can increase the nutrition of plants or produce plant growth hormone, and promote the growth of plants.According to the difference of microbial fertilizer on improving plant nutrient elements, five kinds of microbial fertilizer suitable for pollution-free crops are introduced.

Nitrogen-fixing bacteria fertilizer.The process of converting molecular nitrogen in the atmosphere into ammonia that can be absorbed by crops by microorganisms, either self-generated or symbiotic with plants, is called biological nitrogen fixation.Biological nitrogen fixation is in extremely mild under normal conditions of biochemical reactions, do not need high temperature, high pressure and catalyst in chemical fertilizer production, therefore, biological nitrogen fixation is the cheapest, the cleanest, most efficient fertilization process.Nitrogen can be fixed in the air in the soil and in the roots of many crops, providing nitrogen nutrition for crops and secreting hormones to stimulate crop growth.This kind of fertilizer mainly has self - generated nitrogen-fixing bacteria, combined nitrogen-fixing bacteria and so on.

Rhizobium fertilizer.Rhizobia fertilizer, it is to point to a biological fertilizer, with plenty of rhizobia can form nodules on leguminous plant root, assimilation of nitrogen in the air, improve the leguminous plant nitrogen nutrition, there are mainly the rhizobia agent such as soybean, peanut, green beans.Rhizobia fertilizer is mainly used for seed dressing, before seeding, the bacterium agent and right amount water and mix into a paste, and seed mix evenly, again in shade, after a little dry mix a small amount of mud, and finally mixed phosphate, potash, or add a small amount of molybdenum, boron, weifei, sow immediately.The amount of rhizobium fertilizer depends on the type of crop and the quality of the fungicide. For example, soybean generally USES 375-15000 billion live rhizobium bacteria per hectare.More than 300 million) about 2,250 grams per hectare. Be careful not to mix the mixed bacteria and pesticides into the seed dressing, so as not to affect the activity of rhizobia.In addition, because rhizobia has specificity, seeds should be selected according to the characteristics of the fungicide when applied, otherwise, nodules and nitrogen fixation cannot be achieved.For example, soybean rhizobia can only be used in crops such as soybeans and black beans, but not in crops such as peas and ziyun ying.

Phosphorus bacterial fertilizer.Phosphorus bacterial fertilizer is a kind of microbial product that can strongly decompose organic or inorganic phosphating substances.It can transform the insoluble phosphorus in soil into the effective phosphorus that can be used by crops and improve the phosphorus nutrition of crops.Its species are phosphorus bacteria, phosphorus - free fungi and so on.Phosphorus bacterial fertilizer can be divided into liquid phosphorus bacterial fertilizer, solid phosphorus bacterial fertilizer and granular phosphorus bacterial fertilizer according to different production dosage forms.Application method: the application of phosphorus bacterial fertilizer to phosphorus deficient but organic rich soil has a good effect. It is suitable for various crops and requires early concentrated application.It can also be used as base fertilizer or fertilizer.The specific application amount shall be subject to the product description.(1) basal.It can be mixed with farmyard fertilizer and then applied in ditch or hole.(2) fertilizer.The fertilizer was applied to the root of the crop before flowering.(3) the seed.Add some water into the phosphorus bacterial fertilizer and make a paste. Add the seeds and mix them.Seed mixing is commonly used with the mix, after the mix is not used temporarily, should be placed in a cool place cover preservation.When transplanting crops, it is advisable to use the method of dipping seedlings.

Silicate bacterial fertilizer.It can decompose aluminosilicate and apatite containing potassium such as mica and feldspar in soil, release potassium, phosphorus and other ash elements, and improve the nutritional conditions of plants.There are mainly silicate bacteria, other potassium - soluble microorganisms and so on.Silicate bacteria fertilizer dosage form at present is mainly grass carbon adsorption of solid dosage forms, its production conditions, technical requirements, quality requirements, how to use the same as the general microbial fertilizer, mainly used in potassium deficiency.The problem of lack of potassium in agricultural soil in China is becoming more and more obvious, and the production capacity of potassium fertilizer in China is seriously insufficient, which needs to be imported every year.Actually there's no shortage of total potassium content in soil is only available k in short supply, research and development and utilization of releasing from microbes, to clarify the mechanism of microbial fertilizer is an important topic of research and application.Silicate bacteria fertilizer is used for crop variety, in cotton, tobacco, sweet potato, corn and fruit trees shows good effect, such as increased about 10% of production, and can improve the quality.The main application methods are seed mixing, hole application and off-root fertilizer application.

Compound bacteria fertilizer.Contains more than two of the above beneficial microorganisms, which are not antagonistic to each other and can improve the supply level of one or more nutrient elements in crops, and contain physiological active substances.

Above is the method that planting pollution-free crop chooses microorganism fertilizer, everybody can combine actual situation of planting, choose reasonably.
