Problems solved by technology

Nowadays, in order to reduce the incidence of navel rot in crops, many organic fertilizers have been developed, but there is no water-soluble fertilizer formula specifically for navel rot
[0005] Due to the antagonistic effect of crops on nutrient absorption, high-calcium formula fertilizers cannot guarantee the effective absorption of calcium elements. Improper proportioning will lead to the absorption of nutrients and the symptoms of crop deficiency. Therefore, a scientific high-calcium fertilizer has been developed. It is necessary to formulate water-soluble fertilizer so that the crops can effectively absorb the calcium element in the fertilizer and maintain its balanced nutrition

Abstract

The invention provides a water-soluble fertilizer for preventing blossom-end rot, and applications thereof, wherein the water-soluble fertilizer comprises: 28 parts of potassium nitrate, 47.2 parts ofcalcium nitrate, 12.3 parts of magnesium nitrate, 0.5-30 parts of potassium polyphosphate, 1.3-1.5 parts of EDTA-Fe, 0.6-0.7 part of EDTA-Mn, 0.25-0.3 part of EDTA-Zn, 0.25-0.3 part of EDTA-Cu, 0.101parts of boric acid, and 0.024 part of sodium molybdate, and the polymerization degree of the potassium polyphosphate is 2-15. According to the present invention, the water-soluble fertilizer has good water solubility, contains twelve nutrition elements, and can make crops fully absorb the calcium element in the fertilizer while cannot affect the absorption of other nutrition elements, such thatcrops can be prevented from blossom-end rot while grow in a balance state without element deficiency symptoms.

Description

[0001] Technical field: [0002] The invention belongs to the field of agricultural irrigation and fertilization, and in particular relates to a high-calcium water-soluble fertilizer and its application. [0003] Background technique: [0004] Calcium is an essential nutrient element for plants and plays an important role in plant growth and development. For example, calcium can form calcium pectate with acid to stabilize the structure of the cell wall; calcium can link phospholipid molecules to stabilize the cell membrane; most of the cells in the cell Calcium exists in the vacuoles, and plays an important role in the balance of anions and cations in the vacuoles, and has an osmotic regulation effect. For some crops, such as tomato, pepper, etc., calcium or boron deficiency will produce "umbilical rot". The disease develops quickly and becomes dark brown, the pulp loses water, and the top is sunken, and generally does not rot. When the air is humid, the diseased fruit is ofte...
