Embodiment 1

[0029] Embodiment 1 saline-alkali land uses water-saving nutrition bowl

[0030] It includes a pot body, the pot body is provided with a plurality of air holes, and the pot body includes the following components by weight: 50 parts of crop straw, 10 parts of animal manure, 5 parts of organic bentonite, 2 parts of modified rectorite, 2 parts of humus, 2 parts of compound fertilizer, 0.5 parts of polyacrylamide.

[0031] The animal dung is cow dung, and the crop straw is wheat straw.

[0032] The rectorite is ground into a fine powder with a ball mill and calcined, then organically modified with cetyltrimethylammonium bromide as an intercalation agent, and finally the modified organic rectorite is melted with polypropylene Mixed on a twin-screw screw machine to prepare modified rectorite.

[0033] The compound fertilizer is formed by mixing potassium fertilizer, phosphorus fertilizer and nitrogen fertilizer in parts by weight of 2:1:1.

Embodiment 2

[0034] Embodiment 2 saline-alkali land uses water-saving nutrition bowl

[0035] Including a bowl, the bowl is provided with a plurality of air holes, and the bowl includes the following components by weight:

[0036] 55 parts of crop straw, 12 parts of animal manure, 8 parts of organic bentonite, 3 parts of modified rectorite, 3 parts of humus, 5 parts of compound fertilizer, and 0.8 part of polyacrylamide.

[0037] The animal manure is chicken manure, and the crop stalks are wheat stalks and corn stalks.

[0038] The compound fertilizer is formed by mixing potassium fertilizer, phosphorus fertilizer and nitrogen fertilizer in parts by weight of 2:1:1.

Embodiment 3

[0039] Embodiment 3 A kind of water-saving nutrition bowl for saline-alkali land,

[0040] Including a bowl, the bowl is provided with a plurality of air holes, and the bowl includes the following components by weight:

[0041] 50-60 parts of crop straw, 10-15 parts of animal manure, 5-10 parts of organic bentonite, 2-5 parts of modified rectorite, 2-5 parts of humus, 2-5 parts of compound fertilizer, 0.2-0.7 parts of biological flora part, polyacrylamide 0.5-1 part.

[0042] The crop straw is a combination of wheat straw, corn straw, potato straw and cotton straw. The animal manure is a mixture of cow manure and chicken manure. The biological flora is Bacillus subtilis, nitrogen-fixing bacteria and silicate bacteria.

Abstract

The invention discloses a water-saving nutrient pot for saline-alkali soil. The water-saving nutrient pot for saline-alkali soil comprises a pot body, wherein a plurality of ventilation holes are formed in the pot body; the pot body is prepared from the following ingredients in parts by weight: 50 to 60 parts of crop stalks, 10 to 15 parts of animal manure, 5 to 10 parts of organobentonite, 2 to 5 parts of modified rectorite, 2 to 5 parts of humic mattesr, 2 to 5 parts of compound fertilizers and 0.5 to 1 part of polyacrylamide. The invention also discloses a preparation method of the water-saving nutrient pot. The method comprises the steps of material preparation, mixing, pressing forming, drying and the like. The nutrient pot is made of degradable materials; nutritive substances required for crop growth can be provided; in addition, the water storage effect is good; after the degradation, the soil can be improved; the water-saving nutrient pot is particularly suitable for being used in the saline-alkali soil.

Description

technical field [0001] The invention relates to the technical field of saline-alkali land improvement and planting, in particular to a water-saving nutritional bowl for saline-alkali land and a preparation method thereof. Background technique [0002] Saline-alkali land is a kind of soil type widely distributed in the world, and it is an important land resource. The saline-alkali land area in the world is about 15 billion mu, and the saline-alkali land area in my country is about 540 million mu, accounting for one-thirtieth of the world; the saline-alkali land in my country is about 90 million mu, and the cultivated land in my country is only 1.5 billion mu, accounting for nearly one-tenth of the cultivated land area in my country. one fifth. At present, it has become the biggest obstacle restricting the construction of ecological environment and the sustainable development of agriculture in our country. At the same time, with the reclamation of large areas of land, soil sa...
