Pear tree fertilizer composition for planting in saline-alkali land

Abstract

The invention relates to a pear tree fertilizer composition for planting in saline-alkali land. The pear tree fertilizer composition comprises EDDHA-Fe, EDTTi-Zn, accelerants and fertilizers containing other elements. Humic acid is contained, so the pH value of the soil of the saline-alkali land can be effectively adjusted, the soil pH value change caused by EDEDHA-Fe dissolution is adjusted, and the efficient absorption of Fe elements released by the EDDHA-Fe can be promoted; and P has an antagonistic effect on the absorption of Zn and Fe, so the occurrence of the antagonistic effect can also be reduced through the addition of the humic acid. The EDDHA-Fe and the EDTTi-Zn can effectively supplement trace elements such as the Fe and the Zn. Organosilicon assistant silicon and nonionic organic silicon surfactants can greatly reduce the surface tension of a medicament system, can improve the spreadability and the wettability of medicament liquid, and can enhance the leaf surface penetration of medicaments. Biological agents contain a great number of microbes, the nutrition conditions of crops are improved through the vital movement of the microbes in the soil, and the absorption of mineral elements is promoted. Therefore the yield of pear trees planted on the saline-alkali land is improved, and the quality of fruit products is improved.

Description

1. Technical field [0001] The invention relates to a pear tree fertilizer composition, in particular to a pear tree fertilizer composition for planting in saline-alkali land. 2. Background technology [0002] The planting of pear trees is not only carried out on mountainous land, but also on saline-alkali land now, so the pear tree fertilizer composition for planting in saline-alkali land is an important agricultural resource. Among plants, because pear trees are suitable for planting in soil with a pH of 5.6-7, but because iron ions are fixed on saline-alkali soil, the effective iron ion content is low, and pear trees planted on saline-alkali soil are prone to physiological diseases such as iron deficiency. Lead to yellowing of leaves, yield and quality reduction, in the existing methods of prevention and treatment of iron deficiency in pear trees planted on saline-alkali land, mainly soil application or foliar spraying of ferrous sulfate, but ferrous sulfate is easy to oxi...

AI Technical Summary

Problems solved by technology

The effect of applying most iron fertilizers to soil is not ideal, mainly because iron will quickly transform into insoluble oxides

[0004]The traditional way to reduce the pH value of saline-alkali land is to irrigate the salt with fresh water, which can only temporarily adjust the pH value of the pear orchard, but cannot fundamentally improve the physical and chemical properties of the soil

In addition, the existing methods for preventing and treating iron deficiency in pear orchards are mainly soil application or foliar spraying of ferrous sulfate, but ferrous sulfate is easy to oxidize and the effect is unstable and the effect is not good.
