Special potassium-rich fertilizer for strawberries and preparation method thereof

Abstract

The invention discloses a special potassium-rich fertilizer for strawberries. The fertilizer is prepared from the following raw materials in parts by weight: 24-32 parts of rice chaff ash, 40-60 part of hay carbon soil, 10-12 parts of sodium alginate, 6-8 parts of peanut shells, 4-5 parts of monoammonium phosphate, 3-4 parts of urea formaldehyde, 8-12 parts of potassium chloride, 6-8 parts of zinc sulfate, 5-7 parts of tobacco leaves, 5-6 parts of turnips, 12-16 parts of attapulgite, 5-6 parts of biogas liquid, 28-36 parts of leaf mould, 10-14 parts of garden soil, 3-4 parts of JT fungicide, 4-5 parts of a soil modifier and a proper amount of vegetable washing water. According to the fertilizer disclosed by the invention, by using hay carbon soil, leaf mould, rice chaff ash and the like as main raw materials, the content of a potassium fertilizer is increased, and attapulgite, peanut shells, biogas liquid and the like are further added, so that the content of other nutrients of the fertilizer are extremely increased. Meanwhile, the fertilizer has beneficial effects on loosening and improving soil. Combination of urea formaldehyde with potassium chloride and monoammonium phosphate integrates slow release and controlled release so as to provide nutrients to strawberries continuously, so that the use level of the fertilizer is saved and the fertilizer has a good economic value.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a special potassium-rich strawberry fertilizer 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". ".
