Biological bacterial fertilizer is a kind of microorganisms that have been selected from the wild and cultivated legumes by modern high-tech means to be mutagenized and rejuvenated, then industrially fermented, and processed with high quality grass carbon or brown coal as a carrier. High bacterial content of biological agents. Its product types include: multi-functional compound fertilizer, single bio-potassium fertilizer and single bio-phosphorus fertilizer.
First, the efficacy characteristics of biological fertilizer
1. Biological bacterial fertilizer contains a large number of biological bacteria, through the activities of biological bacteria, not only can improve the physical and chemical properties of the soil, improve the content of soil organic matter, and has the functions of potassium, phosphorus release and nitrogen fixation. After the biological bacterial fertilizer is applied to the soil, the biological bacteria will proliferate rapidly, forming a group of dominant nitrogen, phosphorus, and potassium that are fixed in the soil and can not be absorbed by the plant, and the free nitrogen in the air is fixed for plant absorption and utilization.
2. Biological bacterial fertilizer will not cause side effects on crops. The biological bacteria can produce endogenous hormones such as gibberellin and other active substances in the process of proliferation and metabolism in the soil, which can regulate physiological processes by itself and will not cause side effects on crops.
3. Biological bacterial fertilizer can promote rooting, emergence and early maturity of crops, improve the stress resistance of crops, and show the effects of disease resistance, drought resistance and lodging resistance.
4. The biological bacterial fertilizer itself is non-toxic and non-residue, and can decompose the residual fertilizer and pesticide residues in the soil, dissolve the heavy metal residues after sewage irrigation, and purify the environment, which is the preferred fertilizer in the production of green agricultural products.
5. The biological bacterial fertilizer is mostly based on high-quality grass carbon, and the grass carbon contains a large amount of trace elements necessary for plants. This is not available in other chemical fertilizers.
Second, the application technology of biological bacterial fertilizer
1. The effect of biological fertilizer fertilizer is long. Because the biological bacteria have strong vitality, the general fertilizer efficiency can reach 150-180 days, and only one application of one season crop can meet the requirements of the growth and development of the crop.
2. Biological bacterial fertilizer is an active bacteria. It must be buried in the soil when applied. It should not be applied to the surface. Generally, it should be applied 7~10cm deep. Since the biological bacteria do not cause any damage to the roots and seeds of the crop, the biological fertilizer should be applied as close as possible to the root of the crop to maximize the contact with the root of the crop, so as to fully exert the fertilizer effect of the biological fertilizer. When planting fertilizer, apply it 2~3cm directly below the seed; it is better to be close to the root system when topdressing; when spraying on the foliar surface, it should be carried out after 3 pm and sprayed on the back of the leaf to prevent ultraviolet rays from killing. Species.
3. The effect of biological bacterial fertilizer combined with other fertilizers is good. Because biological bacterial fertilizer is a high-bacteria biological preparation, it takes 15 to 20 days to apply fertilizer effect after applying to the soil. Most of the biological bacteria need to be revitalized under the action of nitrogen, so it is necessary to apply proper amount when applying biological fertilizer. With a small amount of nitrogen fertilizer, generally apply 225-300kg of compound bio-fertilizer per hectare, and according to different conditions, apply 45-75kg urea and 75kg diammonium phosphate. If combined with organic fertilizer (generally applied with high-quality organic fertilizer 30,000 kg per hectare), it can speed up the improvement of soil physical and chemical properties, increase soil organic matter content, and improve the activity of biological bacteria.
4. Maintain suitable temperature and humidity conditions for the soil: the biological bacterial fertilizer can be applied under the soil conditions of soil water holding capacity of 30% or more, soil temperature of 10-40 ° C, and pH value of 5.5-8.5. When the soil water holding capacity is less than 30%, timely watering should be carried out, and the loose soil should be cultivated in time to maintain the soil moisture and increase the soil temperature.
5. Preparation of nutrient soil: Biological fertilizer can prepare nutrient soil for various crops, generally take 60kg of garden soil (landless soil not contaminated by pesticides), fully fermented and decomposed human, animal and poultry manure 30kg, plus compound bacteria 10kg of fertilizer, fully stirred evenly. The nutrient soil can be used for seedlings, raising seedlings, etc. of crops, vegetables, fruits, fruit trees, and the like.
