Q:How about the effect of halving the biological fertilizer?
The use of fertilizer by half the amount of fertilizer with half the amount, and the effect is still very good, is a good product, like a ~
Q:China's best bio-fertilizer
China's best creature is farm manure (organic fertilizer). Natural pollution-free, crop disease resistance, the ancestors left the "crop of a flower, thanks to manure." Yes.
Q:Can bio - fertilizer replace organic fertilizer?
As a typical representative of high-quality microbial fertilizer, gold baby microbial fertilizer, often used to be called bio-fertilizer, gold baby microbial fertilizer is a kind of "vitality" of microbial agents, with nitrogen, phosphorus and potassium solution function. Hundreds of millions of functional bacteria in the soil to form hundreds of millions of "bio-fertilizer plant", can promote crop nutrient absorption and utilization, improve fertilizer utilization, reduce fertilizer use; effective restoration of soil fertility, reduce soil compaction, improve soil supply Fertilizer capacity; to enhance crop resistance, improve crop yield and improve crop quality; a variety of functional microbial organisms into the soil, the growth and reproduction process to produce a large number of secondary metabolites, these products can promote soil aggregate structure form.
Q:Is the bio-fertilizer organic or inorganic?
Organic fertilizer refers to the organic matter-based natural fertilizer, mostly man and animal feces and animal and plant residues, divided into farm manure, green manure and humic acid three categories. Grass ash fertilizer due to vegetation ash for the plant after burning ashes, it is low cost, nutrient complete, fertilizer effect of farm manure.
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 is the use of biological bacteria fertilizer? What needs attention
Ask a professional to ask
Q:Biological fertilizer implementation standards?
Silicate Bacteria Fertilizers
Q:What are brown sugar bio-fertilizers?
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, improve Continuous fertilization capacity; the second is a significant inhibition of cotton, melon fusarium wilt and rice sheath blight and other diseases, enhance resistance.
Q:What are the types of microbial fertilizers?
phosphate bacteria fertilizer. Can be difficult to dissolve the soil phosphorus, can be used as crop available phosphorus, increase the content of available phosphorus in the soil for crop absorption and utilization.
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.
