A plant-regulator-containing fertilizer for saline-alkali land and applications thereof in plantation of euonymus fortunei

Abstract

A plant-regulator-containing fertilizer for saline-alkali land and applications thereof in plantation of euonymus fortunei are provided. The plant-regulator-containing fertilizer comprises 9-10 parts of nitrilotriacetic acid, 9-11 parts of fulvic acid, 20-25 parts of maleic anhydride, 31-33 parts of a nitric phosphate fertilizer, 7-9 parts of amino acid salts, 30-35 parts of humic acid, 1-2 parts of ferrous sulfate, 2-3 parts of zinc nitrate, 1-2 parts of calcium nitrate, 2-3 parts of ammonium paramolybdate, 8-9 parts of pyruvic acid and 0.1-0.5 part of abscisic acid. The plant-regulator-containing fertilizer can effectively improve saline-alkali land soil. After improvement, the soil salt content is reduced to 0.2-0.3%, the soil pH value is reduced to 7.3-7.5, the degree of alkalization of the soil is reduced to 0.1-0.2%, soil humus is increased by 70-74%, the soil microbe content is increased by 30-40%, the total nitrogen content of the soil is increased by 50-58%, and the content of trace elements in the soil is increased by 20-23%.

Description

technical field [0001] The invention provides a fertilizer and its application, in particular to a fertilizer containing a plant regulator for saline-alkali land and its application in planting vines, belonging to the technical field of soil fertilizers. Background technique [0002] In the work of artificially transforming saline-alkali land, there are many methods. At present, most of the costly and labor-intensive methods such as backfilling with foreign soil, irrigation and salt washing are used; the so-called irrigation and salt washing: according to the law of "salt comes with water, salt goes with water", water is poured into the ground to form a certain amount of water on the ground. The deep water layer fully dissolves the salt in the soil, and then drains the dissolved salt from the drainage ditch; thereby reducing the salt content of the soil. [0003] These methods have no obvious effect on improving the soil, and can only be alleviated for a short time. Over ti...

Problems solved by technology

[0003] These methods have no obvious effect on improving the soil, and can only be alleviated for a short time. Over time, the soil will become salinized again; there is another method, that is, to use chemical amendments to improve the soil; to improve the soil; this method can better improve the soil; but this method requires the preparation of special fertilizers, which is a direction worthy of further study

[0004] The current fertilizers for improving saline-alkali land have the following defects: 1. They cannot simultaneously improve soil pH, salinity, and high alkalinity; 2. The effects of increasing humus content, microbial content, total nitrogen content, and trace elements in the soil are not obvious ; 3, using existing fertilizers to plant plants in saline-alkali soil, the survival rate is low
