Problems solved by technology

High-quality potatoes are inseparable from good fertilizers. The main nutrients absorbed by potatoes are nitrogen, phosphorus, potassium, calcium, etc., but there are still many problems in ordinary fertilizers. First, compound fertilizers are easy to agglomerate and have a rough surface, which is not conducive to Absorb the nutrients in the compound fertilizer; secondly, the potato plants have poor adaptability to the soil, weak disease resistance, and the quality of the potato fruits grown is not ideal; finally, the potato plants are prone to insect damage, and the leaves are easy to be eaten

Abstract

The invention relates to the technical field of chemical manufacture, in particular to a special compound fertilizer for potatoes and a preparation method of the special compound fertilizer. The special compound fertilizer comprises potassium sulfate, urea, calcium phosphate, monopotassium phosphate, bamboo charcoal fibers, sodium borate, magnesium nitrate, additives, acidity regulators and inducers. The additives are added, and the surface tension of the compound fertilizer in the granulation process can be reduced, so that flowability and viscosity can be improved. After being dried, the compound fertilizer is not easily caked, the surface of the compound fertilizer is smooth, nitrogen fixation can be improved, and plants can be promoted to absorb nutritional components in the compound fertilizer. The inducers are added, high-efficiency photosynthesis of potato plants can be promoted, and the synthetic ratio of organic matters is increased. Besides, cell activity of the potato plantscan be improved, and growth and development are accelerated, so that yield is improved. The inducers contain ecdysteroid, injurious insects can enter an exuvial period in advance and can be transformed into an adult, and excessive invasion of the potato plants by the injurious insects is avoided.

Description

technical field [0001] The invention relates to the technical field of chemical manufacturing, in particular to a special compound fertilizer for potatoes and a preparation method thereof. Background technique [0002] Potatoes, Solanaceae Solanum, annual herbaceous plants, also known as ground eggs, yams, potatoes, etc. Potatoes are one of the five staple foods in China. With high nutritional value, strong adaptability and large yield, potatoes are the third most important food crop in the world, second only to wheat and corn. Potatoes are tubers that reproduce and can be used as medicine. They are flat in nature and sweet in taste, and can cure stomach pain, ribs, carbuncles and other diseases. High-quality potatoes are inseparable from good fertilizers. The main nutrients absorbed by potatoes are nitrogen, phosphorus, potassium, calcium, etc., but there are still many problems in ordinary fertilizers. First, compound fertilizers are easy to agglomerate and have a rough s...
