Embodiment Construction

[0041] The following examples are further detailed descriptions of the present invention.

[0042]The use of the slightly soluble crystals in the salt pond of the present invention as a plant fertilizer, the method of using the slightly soluble crystals in the salt pond as a plant fertilizer is as follows: Throwing and removing the slightly soluble crystals in the salt pond on the soil surface, or deep plowing into the soil in combination with a rake It can be used as basal fertilizer, or applied in furrows or holes, or combined with sowing as seed fertilizer, and the usage rate is 23g / m 2 .

[0043] When in use, the slightly soluble crystals in the salt pond are first washed with water to remove chlorine salt, and then used as fertilizer.

[0044] The slightly soluble crystals in the salt pool are translucent, mainly monoclinic crystals, a small amount are hexagonal crystals, and are slightly soluble in water.

[0045] The ion content of the slightly soluble crystals in the...

Abstract

The invention discloses application of slightly-soluble salt pond crystals as a plant fertilizer. A method for using the slightly-soluble salt pond crystals as the plant fertilizer comprises the following steps: spreading the slightly-soluble salt pond crystals onto the surface of soil, or deeply ploughing the slightly-soluble salt pond crystals into the soil as a base fertilizer in combination with a harrow, or ditching for row applying and hole applying, or using the slightly-soluble salt pond crystals as a seeding fertilizer in combination with a seeding process, with the using amount of 23g/m<2>; in the using process, rinsing the slightly-soluble salt pond crystals to remove chlorine salts first and then using the slightly-soluble salt pond crystals as the fertilizer. The slightly-soluble salt pond crystals are better inorganic compound fertilizer and can comprehensively provide calcium fertilizer, magnesium fertilizer, sulfur fertilizer and potassium fertilizer for plants; the slightly-soluble salt pond crystals can be obtained on site and are renewable resources and low in cost; according to local conditions, waste are turned into treasures, so that a long-term misunderstanding that the slightly-soluble salt pond crystals are taken as wastes and must be cleared away is solved.

Description

technical field [0001] The invention relates to the technical field of reuse of seawater salt production products, in particular to the use of slightly soluble crystals in salt ponds as plant fertilizers. Background technique [0002] Slightly soluble crystals in salt ponds, also known as saline-alkali flakes, are produced along with seawater salt production. Seawater with a Baume degree of 2°Bé is introduced into the salt pond to be exposed to wind and sun, and when it reaches 17°Bé, slightly soluble crystals begin to be produced at the bottom of the salt pond Minerals (called saline-alkali flakes locally) begin to form salt when the temperature reaches 25°Bé or higher. The salt is above the saline-alkali flakes. Since it does not affect the salt collection, it has not attracted everyone's attention. [0003] There was a lack of research on the slightly soluble crystalline mineral salts at the bottom of the salt pond. They believed that the slightly soluble crystals at the ...
