Problems solved by technology

[0002] Tomatoes need less fertilizer in the early stage of growth, and a sharp increase in the amount of fertilizer required in the peak period; in terms of the various fertilizers required, the emphasis is on nitrogen fertilizer in the early stage of growth, potassium fertilizer in the later stage, and phosphorus fertilizer throughout the growth period; ordinary fertilizers need to be used during the tomato growth period Repeated topdressing, and can not meet the characteristics of these fertilizer needs of tomato
Existing high-concentration compound fertilizers or compound fertilizers contain insufficient trace elements, requiring multiple fertilizations, reducing fertilizer utilization efficiency

Abstract

The invention relates to the technical field of slow-release fertilizers and discloses a special slow-release fertilizer for tomatoes and a preparation method thereof. The special slow-release fertilizer is prepared from, by weight, 90-100 parts of microporous starch, 75-85 parts of a carrier component, 65-70 parts of organic fertilizers, 10-15 parts of a trace component and 85-95 parts of water. The special slow-release fertilizer is applicable to planting of tomatoes, topdressing is avoided after application of the special slow-release fertilizer, high fertilizer utilization efficiency and low pollution are realized, and tomato quality is improved while tomato growth is promoted.

Description

technical field [0001] The invention relates to the technical field of slow-release fertilizers, in particular to a special slow-release fertilizer for tomatoes and a preparation method thereof. Background technique [0002] Tomatoes need less fertilizer in the early stage of growth, and a sharp increase in the amount of fertilizer required in the peak period; in terms of the various fertilizers required, the emphasis is on nitrogen fertilizer in the early stage of growth, potassium fertilizer in the later stage, and phosphorus fertilizer throughout the growth period; ordinary fertilizers need to be used during the tomato growth period Topdressing is carried out many times within a period of time, and these fertilizer-requiring characteristics of tomatoes cannot be well satisfied. Existing high-concentration compound fertilizers or compound fertilizers contain insufficient trace elements, requiring repeated fertilization, and reducing fertilizer utilization efficiency. Ther...
