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

Abstract

A plant-regulator-containing fertilizer for saline-alkali land and applications thereof in plantation of sword iris are provided. The plant-regulator-containing fertilizer comprises 8-9 parts of nitrilotriacetic acid, 10-12 parts of fulvic acid, 12-14 parts of urea, 8-10 parts of suaeda glauca powder, 6-8 parts of black snake powder, 19-21 parts of maleic anhydride, 30-32 parts of a nitric phosphate fertilizer, 9-11 parts of amino acid salts, 31-32 parts of humic acid, 2-3 parts of ferrous sulfate, 1-2 parts of zinc nitrate, 1-2 parts of calcium nitrate, 2-3 parts of ammonium paramolybdate, 8-9 parts of pyruvic acid, 0.1-0.5 part of abscisic acid, 0.1 part of 2-diethylaminoethyl hexanoate and 0.05 part of jasmonic acid. The plant-regulator-containing fertilizer can effectively improve saline-alkali land soil. After improvement, the salt content of soil layers having depth of 0-30 cm is reduced to 0.15-0.2%, the soil pH value is reduced to 7.2-7.3, the soil humus content is increased by 60-65%, and the total nitrogen content of the soil is increased by 58-59%.

Description

technical field [0001] The invention provides a fertilizer and its application in planting iris, in particular to a fertilizer containing a plant regulator for saline-alkali land and its application in planting iris, belonging to the technical field of soil fertilizers. Background technique [0002] There are large areas of saline-alkali land in my country, many of which cannot effectively grow plants due to high salinity and alkalinity; in the work of artificially transforming saline-alkali land, most of them use costly and labor-intensive methods such as backfilling with foreign soil. [0003] The guest soil is to replace the soil. The guest soil can improve the physical properties of the saline-alkali land; it can suppress salt, leaching salt, compress alkali and increase strength; the role of soil fertility can reduce the salt content of the soil to the extent that it will not harm the growth of crops; these methods The improvement effect on the soil is not obvious, and ...

AI Technical Summary

Problems solved by technology

[0002] There is a large area of ​​saline-alkali land in our country, and many saline-alkali lands cannot effectively grow plants due to high salt and alkalinity; in the work of artificially transforming saline-alkali land, most of them use costly and labor-intensive methods such as backfilling with foreign soil

[0003] The guest soil is to replace the soil. The guest soil can improve the physical properties of the saline-alkali land; it can suppress salt, leaching salt, compress alkali and increase strength; the role of soil fertility can reduce the salt content of the soil to the extent that it will not harm the growth of crops; these methods The improvement effect on the soil is not obvious, and it can only be relieved for a short time. After a long time, the soil will become salinized again.

[0004] Another method is to use chemical amendments to improve the soil; use specific fertilizers to improve the soil by planting saline-alkali-tolerant plants; this method can improve the soil better, but this method requires the preparation of special special fertilizers, This is a direction worthy of further study

[0005] The 0-30cm soil layer of heavy saline-alkali land has high salt content, poor soil, and serious lack of nutrients; the current fertilizers used for improving saline-alkali land in heavy saline-alkali land have the following defects: 1. Can not improve soil pH and salt content while improving soil Nutritional structure; 2. The effect of increasing the humus content, microbial content, and total nitrogen content in the soil is not obvious; 3. Using existing fertilizers to plant plants in saline-alkali land, the plant quality is poor
