Organic fertilizer capable of promoting absorption of strawberries to minerals and preparation method of organic fertilizer

Abstract

The invention discloses an organic fertilizer capable of promoting absorption of strawberries to minerals. The organic fertilizer is prepared from the following raw materials in parts by weight: 12 to 18 parts of seaweeds, 35 to 50 parts of corncobs, 8 to 10 parts of saccharose, 30 to 40 parts of rice husk, 6 to 8 parts of pine sawdust, 6 to 8 parts of urea, 4 to 6 parts of monopotassium phosphate, 4 to 5 parts of potassium oxide, 3 to 4 parts of polyvinyl alcohol, 3 to 5 parts of carboxymethyl cellulose, 5 to 8 parts of pine needle leaf powder, 10 to 15 parts of cow dung powder, 28 to 36 parts of river sand, 3 to 4 parts of VA mycorrhiza, 4 to 5 parts of soil modifier and a proper amount of water. On the basis that the corncobs, the river sand, the rice husk and the like are taken as main raw materials, the organic fertilizer can be used for enlarging the absorption range of a strawberry root system due to the added VA mycorrhiza, so that the absorptivity of the strawberries absorbing nutriments from a soil solution is improved and the application dose of fertilizers is reduced; and the organic fertilizer has the functions of enhancing soil fertility and improving soil structures due to the added river sand, seaweeds and cow dung powder. The organic fertilizer cannot generate any pollution on the environment and can be popularized on a large scale in strawberry production.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to an organic fertilizer for promoting mineral absorption by strawberries and a preparation method thereof. Background technique [0002] Strawberry is a perennial herb and a small berry with high economic value. Its fruit is soft and juicy, sweet and sour, delicious, rich in nutrition, beautiful in appearance and rich in aroma. Therefore, it is favored in domestic and foreign markets and is known as the "Queen of Fruits". ". At the same time, there is a strong demand for strawberry fresh fruit consumption in major large and medium-sized cities in China, and fertilizers are an important tool to improve the quality and output of strawberries. At present, there are no common special fertilizers for strawberries on the market, and the traditional inorganic fertilizers cannot fully meet the ratio of various nutrient requirements of strawberries, and will also cause soil compaction,...

AI Technical Summary

Problems solved by technology

At present, there are no common special fertilizers for strawberries on the market, and traditional inorganic fertilizers cannot fully meet the ratio of various nutrient requirements of strawberries, and will also cause soil compaction, soil fertility decline, ecological damage, environmental pollution and agricultural pollution. A series of problems such as the decline in the quality of by-products do not conform to the principle of sustainable agricultural development
