Abstract

The invention discloses a special water-retaining slow-release fertilizer for pitayas. The special water-retaining slow-release fertilizer for the pitayas is prepared by mixing and granulating the following components in parts by weight, functional slow-release granules, a water-retaining agent, urea, a calcium magnesium phosphate fertilizer, diammonium sulfate, potassium sulfate, zinc sulfate, iron sulfate, bacillus amyloliquefaciens, bacillus subtilis and nitrogen-fixing bacteria, and then coating:. The special water-retaining slow-release fertilizer for the pitayas is long in fertilizer efficiency, and loss of the fertilizer due to volatilization and leaching can be greatly reduced, so that the limited fertilizer and water can be fully absorbed and utilized by plants so as to achieve water and fertilizer integration and soil improvement. Through the application of the water-retaining slow-release fertilizer, the farmland irrigation cost can be reduced, so that the purpose of high-efficiency water conservation is achieved. Through the application of the water-retaining slow-release fertilizer, the nutrient utilization rate can be greatly increased, so that pollution to crops andthe environment due to fertilizer application is effectively controlled.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a special water-retaining slow-release fertilizer for dragon fruit and an application thereof. Background technique [0002] Dragon fruit has very high economic value, and integrates the advantages of fruits, flowers, vegetables and medicine. Its fruit is not only edible, but also has very high nutritional value. It is rich in anthocyanins, plant albumin, Vc and dietary fiber, and has become an excellent green health food. Dragon fruit flower is rich in nutrition, unique in function, contains a large amount of active ingredients, has the effects of improving eyesight, reducing fire, preventing high blood pressure, and has a unique curative effect on cough and asthma. Pitaya flowers can be made into dried vegetables as raw materials for soup or to prepare health functional drinks, and become a health food with both vegetables and teas. At present, drago...
