Abstract

The invention provides a water flush fertilizer containing azadirachtin for saline-alkali soil. The water flush fertilizer is prepared from the following components in parts by mass: 35-40 parts of maleic anhydride, 8-16 parts of citric acid, 6-8 parts of nitrogen fertilizer, 12-15 parts of biochemical fulvic acid, 1-3 parts of urea iron, 2-3 parts of ammonium manganous sulfate, 12-16 parts of amino acid salt, 2-5 parts of azadirachtin, 3-4 parts of methyl anyl alcohol and 20-25 parts of water. The invention also provides a preparation method of the water flush fertilizer and the application of water flush fertilizer in sea-buckthorn planting. The water flush fertilizer has the beneficial effects that the 5-7mm water-stable aggregate mechanical stability is improved to the range of 601.5-623.3g, the total porosity, the aeration porosity and the water-holding capacity of the soil are improved to the range of 4.9-6.5%, the range of 18.8-22.4% and the range of 5.9-7.6, respectively, the pH value of the soil is reduced to the range of 7.5-7.6 and the degree of alkalization of the soil is reduced to the range of 11.2-11.9%, and the transplanting survival rate of the sea-buckthorn is 95.6-97.8%.

Description

technical field [0001] The invention provides a fertilizer and its application in seabuckthorn planting, specifically relates to azadirachtin-containing fertilization in saline-alkali land and its application in seabuckthorn planting, and belongs to the technical field of soil fertilizer. Background technique [0002] In the process of utilization of saline-alkali land, simply speaking, it can be divided into light saline-alkali land, moderate saline-alkali land and heavy saline-alkali land. The salt content exceeds 6 / 1000, the emergence rate is less than 50%, and the pH value of the soil moisture exceeds 8.5, causing soil compaction, which has an inhibitory effect on the root system of the crops, making the crops not grow or grow unhealthy; the moderate saline-alkali land is between between the two. For the improvement of saline-alkali land, chemical methods have a better effect. Chemical improvement is to apply some acidic salts to improve the properties of saline-alkali ...
