Abstract

The invention relates to a medical fertilizer and a method for making the same. The medical fertilizer has granular shape and consists of a kernel body and at least one lagging cover, wherein, the kernel body is granular substance and the lagging cover is powder or liquid. The medical fertilizer and the method for making the same ensure that the farm chemical and the fertilizer can sufficiently work and various effective compositions are not affected; the particles such as urea are taken as kernel part and the powder or liquid farm chemical or the fertilizer, etc. are used to produce the medical fertilizer in a lagging cover way.

Description

technical field [0001] The invention relates to the field of medicinal fertilizers, in particular to granular medicinal fertilizers and a preparation method thereof. Background technique [0002] The use of pesticides and chemical fertilizers has ensured increased agricultural production and stable income. Fertilizer is the food of crops and the material basis for increasing production. There is a Chinese agricultural proverb that "planting the land without manure is equivalent to fooling around". According to the statistics of the United Nations Food and Agriculture Organization, the role of chemical fertilizers in increasing food production includes the fertilizer effect of the season and the aftermath. The average yield increase effect is 50%. The results of soil fertility monitoring in my country in recent years show that the contribution rate of fertilizers to the yield of agricultural products is 57.8% on average nationwide. China feeds 22% of the world's population wi...
