Biopotash fertilizer and its application technology

In the rural survey, some farmers knew much about common potassium fertilizers such as potassium sulfate and potassium chloride when using potash fertilizer. When talking about biological potash fertilizer, they were completely ignorant and it was necessary to introduce the knowledge to farmers.
The use of silicate bacteria to decompose soil rock minerals, and then release the effective potassium for crop utilization, and from the 80s of last century, Chinese scientists have successfully selected some excellent strains from these silicate bacteria, and cultivated and fermented through special techniques. Made of silicate bacteria, which is what we call biological potassium fertilizer.
After bio-potassium fertilizer passed technical appraisal in April 1988, it has been applied to more than 20 kinds of crops in more than 20 provinces and cities. After application, it can not only supplement the deficiency of potassium, magnesium, phosphorus, silicon and other nutrients of crops, but also produce a variety of biological active substances, promote the growth and development of crops, and enhance the ability of crops to resist cold and drought and resist pests and diseases. For example, in the rice, corn, wheat, cotton, sweet potato, peanut, tobacco and other crops on the Mushi 0.5 kg of potassium fertilizer, Muping increase production are more than 10%, while the fertilizer is also widely used in rape, vegetables, grapes, apples, mandarin The economic crops such as oranges and sugar cane also have significant effects on yield increase. The application of 1 kg of biopotash fertilizer per acre is equivalent to the application of 15 kg of potassium chloride, and the rate of increase is above 15%.
The mechanism of biological K fertilizer is: First, potassium bacteria and minerals produce a series of enzymes after contact, destroy the crystalline structure of minerals, have a strong ability to activate the ash elements such as potassium, phosphorus, magnesium, iron, silicon, etc. in the soil, thus releasing Out of nutrients. It has been observed that under static culture conditions, biopotassium can release 12% of available potassium from orthoclase in 15 days. In 30 days, 51.7% of effective potassium can be released from biotite, so bio-potash fertilizer has the reputation of “opening the soil potassium key”. The second is that after contact between potassium bacteria and rock mineral surface, ion exchange is performed to release potassium, and the organic acid can be secreted to convert insoluble potassium and phosphorus into water-soluble potassium and phosphorus. Potassium bacteria can also secrete physiologically active substances that stimulate the growth of crops, enhance their ability to resist drought and cold, and have certain inhibitory effects on some plant diseases such as wheat rust and rape sclerotinia.
Biopotassium fertilizer is aerobic fertilizer. The growth and development temperature is 25-30°C, which requires less nutrient conditions and can also play a role in poor soil. Biopotash fertilizer can be used as base fertilizer, seed dressing, alfalfa root and topdressing fertilizer. The application of base fertilizer is best. When used as a basal fertilizer, use 2-4 kg of biological potassium fertilizer per acre, add 20-30 kg of soil miscellaneous fertilizer, and spread it in front of the plow. If the biopotassium fertilizer is piled with organic fertilizer for one week, the application effect is better. When seed dressing, mix biological potassium fertilizer with 3-5 times of water into the seeds, or spray the seeds wet and mix fertilizer with the mix. When used for rooting, the raw potassium fertilizer, mud and water are used to make mud, and the roots are planted immediately after rooting. When topdressing, use 3-5 kg ​​of fertilizer per acre and apply it to the roots. Basal fertilizer or topdressing should be applied shallowly, covering the soil after application, which is related to its aerobic characteristics.
Bio-potash fertilizer is a kind of living bacterial fertilizer. During storage and application, care should be taken not to expose it to sunlight. Follow the instructions for use. Special attention must be paid to avoid contact with herbicides and fungicides such as copper sulfate and carbendazim. Or they can not be used or mixed with strong alkaline fertilizers such as ash and lime. The application of bio-potassium fertilizer in the field still has to increase the organic fertilizer, reasonable irrigation and drainage, cultivating loose soil, to create a suitable environment for the growth and reproduction of biological potash fertilizer, in order to facilitate the use of bio-potash fertilizer efficiency.
