Abstract

The invention provides a composite leaf fertilizer. The composite leaf fertilizer comprises 20%-50% of seaweed extract. The seaweed extract is obtained in the mode that fresh seaweed serves as raw materials and is subjected to enzymolysis through alginate lyase. The composite leaf fertilizer further comprises urea, soluble phosphate, soluble magnesium salt, borax and soluble molybdenum salt. The invention further provides a preparing method and application of the composite leaf fertilizer. According to the composite leaf fertilizer and the preparing method and application, the seaweed extract is organically combined with nitrogen, phosphorus, potassium, magnesium, sulfur, boron and molybdenum to form the composite leaf fertilizer, plant absorption can be facilitated, and plant nutritional deficiency symptoms are avoided.

Description

technical field [0001] The invention belongs to the technical field of agriculture and compound fertilizers, and in particular relates to a compound foliar fertilizer containing seaweed extract and a preparation method and application thereof. Background technique [0002] Foliar fertilizers refer to fertilizers that are applied to plant leaves and can be absorbed and utilized by them. Foliar fertilizers can directly enter plants from leaves and participate in the metabolism of crops and the synthesis of organic matter. Especially in the late stage of crop growth and development, its root absorption capacity is weak, and the application of foliar fertilizer at this time can supplement the nutrient deficiency (nutrient deficiency symptoms) caused by insufficient nutrient absorption from the soil. In addition, when the root system of the crop is seriously affected, the foliar fertilizer can make up for the nutrient deficiency suffered by the crop in time. Therefore, rational...
