Q:Bacteria fungus biological fertilizer is good, how much money a ton
A pile of five hair
Q:What bio-fertilizer is used in lotus field
A large number of application of decomposed organic fertilizer. Generally should be built in the pool when the preparation of every 667 square meters of organic fertilizer coated with more than 3000 kg. If the lack of organic fertilizer, can contain nitrogen, phosphorus, potassium and other elements and a variety of trace elements in the fertilizer, mineral fertilizer, microbial fertilizer with a reasonable combination.
Q:Fish pond water clear can be combined with bio - fertilizer compound do
Fish ponds can be used bio-fertilizer compound fertilizer, fish pond fertilization is to promote water quality fertilizer, increase the pool of nutrients, cultivate a large number of natural fish bait, to make up for the lack of food and take an effective measure. Fertilizers are mainly animal manure, manure, green manure and fertilizer. Fertilization methods are two: one is the base fertilizer. Base fertilizer should be early, Shi foot, so you can breed as soon as possible natural food. At the same time after the pool of fat, but also easy to absorb light and heat, improve water temperature, the corresponding extension of fish growth period.
Q:What are the benefits of biological fertilizers?
to enhance plant disease resistance and drought resistance Microbial fertilizer due to the growth and reproduction of a large number of crops in the root, inhibit or reduce the breeding opportunities of pathogenic microorganisms; anti-pathogenic microorganisms, reduce crop diseases; microbial growth, mycelium can increase the The absorption of water, so that the crop drought resistance increased.
Q:The practical significance of bio - fertilizer
the application of bio-fertilizer to a certain extent, improve the physical and chemical properties of the soil. Application of biological fertilizers, due to reduce the chemical fertilizers on soil nutrients, structural and other aspects of the adverse effects, while the microbial activity capacity is enhanced, so the relative improvement of soil physical and chemical
Q:Do you want to make bio - fat
However, the production of bio-fertilizer is not just a biological carrier can be made, the need for a variety of beneficial bacteria, which is good for the crop of microorganisms to fermentation, You can buy some fermented bacteria with bacteria slag used to ferment the fermentation.
Q:What is the use of biological bacteria fertilizer? What needs attention
Biological bacteria fertilizer in the current farming plays an increasingly important position, then in order to improve the use of biological fertilizer effect, we must understand the characteristics of biological fertilizer, crop and application of technology; two to promote "early The application of time to "early", the general for the base fertilizer, fertilizer and fertilizer application; applied from the crop roots to "near"; seeds and fertilizer to mix "uniform." However, there is a bio-fertilizer application has not been caused by farmers attention, this method is dipped in the root. It is understood that the use of bio-fertilizer dip root not only promote the growth of vegetable roots, but also to inhibit the occurrence of root diseases of vegetables have a significant effect, such as eggplant dipped in roots. Eggplant root disease is generally the most prone to the early growth of eggplant, because the eggplant root system is weak, it is easy to be infected by pathogens. The eggplant grow into a plant, the roots of a strong, strong resistance to disease, rarely susceptible. Therefore, to avoid eggplant root disease, should be in the eggplant seedling to do preventive measures, and in the use of biological bacteria before planting dipped in roots. Can be planted in the eggplant before the biological bacteria mixed with soil into the water made of mud, the ratio: 1 kg of fertilizer +3 kg of soil +5 kg of water, with a good, it will stir with a stick. Dip the root, the eggplant roots below the roots of all inserted into the mud, gently stir the two, so that the mud attached to the plant roots, and then can be planted.
Q:Brown sugar, vegetables, water and then filial piety can make biological fertilizer do
Bio-fertilizer, the use of organic fertilizers and inorganic fertilizers, and accompanied by a variety of microbial or high-energy compounds available, very popular with farmers, the effect is more obvious, one can improve soil physical and chemical properties, enhance water retention, fertilizer performance Continuous fertilization capacity; the second is a significant inhibition of cotton, melon fusarium wilt and rice sheath blight and other diseases, enhance the resistance ...
Q:Bio-fertilizer can not make their own
Pure bio-fertilizer can not be a single application, with organic fertilizer, fertilizer with the application in order to give full play to its effectiveness. Such as: soybean rhizobia, phosphorus activator, bio-potash and so on.
Q:Prospects for bio - fertilizer
Bio-fertilizer production cost is low, the application effect is good, does not pollute the environment, not only after the increase in production, but also to improve the quality of agricultural products and reduce the amount of fertilizer in China's sustainable development of agriculture occupies an important position. China's growing population, people's living standards continue to improve, the quantity and quality of agricultural products put forward higher requirements. While the cultivated land is decreasing, the application rate of chemical fertilizer increases, the production cost rises linearly, the environment deteriorates and so on. These conditions provide a good development opportunity for bio-fertilizer. At the same time, the development of bio-fertilizer itself has laid the foundation for expanding the application. The world's population is soaring, and society's demand for food and fertilizer is becoming increasingly urgent. However, it is difficult to maintain the sustainable development of agriculture, and it is necessary to develop bio-fertilizers in the future because of the limited resources of the raw materials and energy sources for fertilizer production. Bio-fertilizer can not only supplement the shortage of fertilizer, and may be listed as green food and fertilizer into the commodity market, become the emerging "green industry" in agricultural production to play its due economic, social and ecological benefits.
