Problems solved by technology

[0005] However, these ferrous irons need to be dissolved in water to be used as a liquid, and are easily oxidized to ferric iron when the iron fertilizer is dissolved and used in solution to reduce the effective iron content
Moreover, the iron fertilizer applied to the soil is easily fixed by soil minerals, and the iron supply capacity is also limited by the absorption capacity of the root system; the ferrous iron sprayed on the foliage has a large contact surface with the air, which is easier to oxidize, and it is easy to form spots on the leaves, which affects the appearance , and even damage the leaves, affecting photosynthesis; the trunk injection of iron fertilizer requires a set of special equipment, the nutrient supply is rapid, and the requirements for pressure, iron concentration and type are relatively high, and fertilizer damage is easy to occur if it is not well grasped; the root infusion needs to be scraped from the soil It takes a lot of labor to find a suitable root system, and the requirements for the concentration and type of iron fertilizer are relatively high. If the control is not good, fertilizer damage will easily occur.

Abstract

The invention discloses compound iron fertilizer special for fruit trees and forest tree branches and an application method of the compound iron fertilizer. A preparation method of the compound iron fertilizer is characterized by including: using saturated ferrous sulfate, saturated ammonium bicarbonate and iron powder to prepare ferrous carbonate containing the iron powder, adding the ferrous carbonate into a certain amount of compound amino acid and citric acid solution under 65-70 DEG C, performing immediate filtration after the reaction, concentrating filtrate, adding clay, kneading into long strips, cutting into cylinders, and airing or drying to obtain the compound iron fertilizer. The application method includes: drilling an inclined hole in a fruit tree or forest tree branch and trunk, placing the compound iron fertilizer into the hole in the trunk, injecting water, and sealing the hole. The compound iron fertilizer has the advantages that the problem that conventional iron fertilizer is prone to oxidation and low in fertilizer efficiency is solved, and the compound iron fertilizer is simple to apply, safe and capable of mildly providing iron nutrients for trees and keeping the absorption effectiveness of the iron nutrients for a long time.

Description

[0001] (1) Technical field [0002] The invention relates to a compound ferritic fertilizer for fruit trees and forest tree branches and trunks, which is suitable for supplementing amino acid and iron nutrition to fruit trees and forest trees through the branches and trunks, and belongs to the field of fruit tree fertilizer production and fertilization. [0003] (2) Background technology [0004] The chlorosis of fruit trees and forest leaves is mainly due to iron and nitrogen deficiency. Ensuring the effective supply of iron and nitrogen nutrients is an effective means to prevent and correct the nutrient-deficient yellow leaves of trees, especially to ensure the effective supply of iron nutrients. At present, the main methods such as soil application, foliar spraying, trunk injection and root infusion are used to supply iron nutrients to trees; because plants can only absorb ferrous iron but not ferric iron, the iron nutrient selected for production Mainly divalent iron, such as iro...
