Plant compound fertilizer

Abstract

The invention discloses a compound fertilizer, in particular to a plant compound fertilizer. The plant compound fertilizer is formed by compounding chelated secondary and trace elements, a potassium fertilizer, urea, ammonium chloride, monoammonium phosphate and attapulgite powder; and humic acid also can be added as required. The plant compound fertilizer of the invention has the characteristicsof reasonable compatibility, simple process, high fertilizer efficiency, high particle strength and balance nutrition, can improve the content and the performance of trace elements in soil, solves the problem of plant diseases caused by lack of the trace elements in a crop growing process, promotes plant growth, increases disease resistance and disaster resistance, improves yield and recovers natural flavor, so the plant compound fertilizer is a novel and specific compound fertilizer.

Description

technical field [0001] The invention relates to the technical field of compound fertilizer, and specifically provides a plant compound fertilizer. Background technique [0002] Among the 16 essential nutrients for plants, carbon, hydrogen, and oxygen are the most needed by crops, and they come from the atmosphere and water; oxygen, nitrogen, and phosphorus mainly come from the soil, and a small part of nitrogen comes from the air; calcium , magnesium and sulfur are three kinds of medium elements, which are mainly supplied by the soil. Iron, boron, manganese, copper, zinc, molybdenum and chlorine are 7 kinds of trace elements, which mainly come from the soil. [0003] At present, most of the fertilizers used in agriculture are compound fertilizers composed of nitrogen, phosphorus, and potassium. Although this compound fertilizer has played an important role in agricultural development and increased production, the elements needed for crop growth are not limited to nitrogen, ...

AI Technical Summary

Problems solved by technology

This kind of compound fertilizer not only cannot supplement trace elements, but if nitrogen, phosphorus and potassium are applied excessively, the mutual antagonism between various nutrients will inevitably occur jointly: in addition to carbon, hydrogen, and oxygen, 13 plant nutrients need to be supplemented. Nutrient elements; however, the problem comes again, new plant nutrient elements are applied to the soil with simple fertilizers, which will cause new antagonism, and will inevitably cause new contradictions. Practice shows that often these simple fertilizers are applied to the soil. Among them, it shows that the fertilizer damage is greater than the fertilizer effect

Although there are many compound fertilizers with added trace elements, since the trace elements have not been chelated, the activity is poor, and the fertilizer damage is often greater than the fertilizer effect after application; although some have been chelated, due to the improper selection of chelating agents, Or the proportion of various nutrients is not suitable, resulting in the failure to increase crop yield and improve quality, and some even produce antagonism, reducing the effect of fertilizers, resulting in fertilizer damage and reduced production
