Abstract

The invention discloses a special improved organic fertilizer for saline-alkali soil. The special improved organic fertilizer comprises the following components by weight: 89%-91% of straw organic fertilizer, 7%-9% of saline-alkali soil modified material, and 1%-3% of medium-micro element additive. The invention further discloses a preparation method for the special improved organic fertilizer for saline-alkali soil. The preparation method comprises the following steps: mixing and piling 89%-91% of the straw organic fertilizer, 7%-9% of the saline-alkali soil modified material, and 1%-3% of the medium-micro element additive by weight to be long strips; uniformly stirring the long strips by a turner, adding hydrolytic polymaleic anhydride organic aqueous solution, and regulating the pH of the solution to be 3-4 to obtain the special improved organic fertilizer for saline-alkali soil. The special improved organic fertilizer for saline-alkali soil can effectively improve soil hardening, increase micro elements and organic nutritional ingredients of humic acid in the saline-alkali soil and improve quality of humus, thereby improving soil fertility and achieving survival rate of planted seedling of more than 95%.

Description

technical field [0001] The invention relates to a special improved organic fertilizer for saline-alkali land. [0002] The invention also relates to a preparation method of the improved organic fertilizer special for saline-alkali land and an application method of the improved organic fertilizer in the saline-alkali land. Background technique [0003] 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 value, it is not conducive to plant growth. [0004] Increasing the application of organic fertilizer is an indispensable measure for saline...
