Water-saving nutrient pot for saline-alkali soil and preparation method thereof

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...

Problems solved by technology

However, these methods have excellent effects on improving saline-alkali land in large areas, and the cost is generally high. They are not applicable to saline-alkali land in some small areas or when planting special varieties.

[0004] In the field of planting, there are more and more applications of nutrient pots to provide crops with the water and nutrients needed for growth, but now there is no nutrient pot suitable for the growth of plants in saline-alkali land, especially in combination with saline-alkali land improvement and crop growth nutrition bowl
