Abstract

The invention discloses a biological potassic fertilizer special for potatoes and a preparation method thereof, and belongs to the field of biological fertilizers. The fertilizer comprises the following components in part by weight: 600 to 800 parts of caw dung and stalk mixture, 100 to 300 parts of grass carbon, 15 to 30 parts of saccharose and 60 to 120 parts of paenibacillus polymyxa strain fermentation broth; and the preparation method comprises the following steps of: culturing and fermenting paenibacillus polymyxa to obtain strain fermentation broth; piling fresh cow dung and stalks forhigh temperature fermentation to obtain the cow dung and stalk mixture; and mixing in the ratio to obtain the fertilizer. The invention is characterized in that: agricultural wastes of cow dung and stalks replace the traditional microbial adsorbent of grass carbon, agricultural waste resources are fully utilized, and environmental pollution is reduced. The biological potassic fertilizer special for the potatoes has obvious yield increasing effect (increasing yield by 11 to 15.4 percent) on the potatoes, and can improve the quality of the potatoes (the starch content is improved by 3.3 to 7.5 percent).

Description

technical field [0001] The invention relates to a fertilizer in agricultural technology, which is a kind of biological fertilizer, specifically a special biological potassium fertilizer for potatoes and a production method thereof. Background technique [0002] Potato is one of the main grains and vegetables in Gansu Province, with an annual cultivated area of ​​658,000 hm 2 above. Due to the one-sided pursuit of high yields by farmers and the extensive use of chemical fertilizers, the quality of potatoes has deteriorated and degraded. As an important agricultural technical measure, the role of microbial fertilizer in the development of high-yield, high-quality, and efficient agriculture has been increasingly recognized by people, which provides considerable room for its development, promotion, and application, especially in The irreplaceability in the development of organic agriculture and the production of A-grade and AA-grade green food fully reflects its potential char...
