Abstract

The invention provides a fertilizer with high saline-alkali soil organic matter content. The fertilizer with high saline-alkali soil organic matter content comprises the following components in parts by mass: 40-45 parts of organic fertilizer, 30-36 parts of peat, 7-10 parts of vermiculite, 5-6 parts of potassium feldspar, 7-10 parts of fulvic acid, 4-6 parts of humic acid, 3-5 parts of compound fertilizer, 0.4-0.6 part of a water retaining agent, 2-3 parts of succinic acid, 1-2 parts of silica gel and 0.3-0.7 part of trace elements. The invention also provides an application of the fertilizer in planting of amorpha fruticosa. The fertilizer with high saline-alkali soil organic matter content has the beneficial effects that the pH value of soil is reduced to 7.4-7.6, and the alkalization degree of the soil is reduced to 6.1-6.5; the total nitrogen content of the soil is increased to 0.12-0.19%; and the fertilizer with high saline-alkali soil organic matter content is applied to planting of amorpha fruticosa in saline-alkali soil, and the transplanting survival rate of the amorpha fruticosa is 96.5-98.6%.

Description

technical field [0001] The invention provides a fertilizer and its application in the planting of Amorpha fruticosa, in particular to a fertilizer with high content of organic matter in saline-alkali land and its application in the planting of Amorpha fruticosa, belonging to the technical field of soil fertilizers. Background technique [0002] With the continuous development of coastal beaches, many difficulties have been encountered in the improvement and utilization of saline-alkali land. In order to make full use of coastal tidal land, people have adopted various methods such as ditches to reduce water and drain salt, inject fresh water to pressurize salt, and set up a spray layer to prevent seepage and separate salt, etc. . However, due to the compaction and barrenness of saline-alkali soil, low fertility and high soil pH, it is not conducive to plant growth. [0003] Increasing the application of organic fertilizer is an indispensable measure for saline-alkali land i...
