Abstract
The invention discloses multicompound fertilizer and a method for making the same. The fertilizer is made from compound mixed major elements, medium elements, minor elements and beneficial element, wherein the major elements comprise nitrogen, phosphorus and kalium; the medium elements comprise sulfur, calcium and magnesium; the minor elements comprise ferrum, zinc, manganese, boron, cuprum and chlorine; and the beneficial element is silicon. The multicompound fertilizer effectively balances the content of each nutrient so as to jointly promote the sound growth of crops; the manufacturing cost per ton of the fertilizer is at least 600 yuan lower than the prior ordinary compound fertilizer containing 45 percent of nitrogen, phosphorus and kalium; the fertilizer is suitable for crops and animals such as grain, fruit, sugarcane, vegetable, flower and grass, tree, edible fungus, fish and shrimp; meanwhile, the fertilizer has excellent effects in increasing both production and income with production increase of between 15 and 50 percent in general, the highest being 60 percent; moreover, crops can mature 3 to 7 days earlier, and can resist drought, lodging and plant diseases and insect pests, etc.; therefore, the multicompound fertilizer is a controlled release multicompound fertilizer with excellent effects.
Description
technical field The invention relates to the technical field of fertilizers, in particular to a multi-component compound fertilizer and a preparation method thereof. Background technique Fertilizers play a very important role in increasing agricultural production and income. There are also various fertilizers on the market, and producers can choose suitable fertilizers according to the nature of the cultivated land. Compound fertilizer is made by physical processing. Among the three nutrients of nitrogen, phosphorus and potassium, there are at least two kinds of fertilizers with marked amounts. According to their total nutrient content, they can be divided into high concentration (≥40%) and medium concentration (≥40%). 30%), low concentration (≥25%). The compound fertilizer has a variety of nutrients, complete nutrients, reasonable nutrient distribution, can promote soil nutrient balance, high fertilizer efficiency and utilization rate, and the compound fertilizer has a ce...
