Embodiment 1

[0025] raw material:

[0026]

[0027] Put the above-mentioned raw materials into the blender together, mix thoroughly, and then send the mixed fertilizer into the metering and packaging machine for metering and packaging. The total nutrients of the obtained pitaya special nutrient synchronous controlled-release fertilizer: nitrogen, phosphorus pentoxide, and potassium oxide contents are respectively 18%, 9%, and 20%, all of which are percentages by mass.

Abstract

The invention belongs to the field of plant cultivation technology, and relates to a synchronous nutrition controlled-release fertilizer specially used for dragon fruits. The fertilizer is prepared by evenly mixing 3-6% reaction film formation polymer coated urea, 3-6% reaction film formation polymer coated compound fertilizer, urea, diammonium phosphate, potassium chloride, calcium-magnesium-phosphorus and magnesium sulfate. Due to the nutrient releasing characteristic of the reaction film formation polymer coated urea and the nutrient absorbing law of the dragon fruits, the single controlled-release fertilizers with different release periods and partial quick-acting fertilizers are compounded with each other, so that the obtained controlled-release fertilizer is long and comprehensive in fertilizer efficiency, and is scientific in nutrient proportion, so that the utilization rate of the fertilizer and the fertilizer efficiency are greatly improved. The synchronous nutrition controlled-release fertilizer specially used for the dragon fruits has good effects proved by field experiments, thus providing support for the development of the industrialization of the dragon fruits.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and relates to a controlled-release fertilizer, in particular to a synchronous controlled-release fertilizer specially used for dragon fruit nutrition containing controlled-release nitrogen. Background technique [0002] Dragon fruit tree is a plant of the genus Cactaceae. It is native to tropical desert areas in Central America such as Brazil and Mexico. It is a typical tropical plant. The fruit of the dragon fruit tree is dragon fruit, English Pitaya, its real name is green dragon fruit, red dragon fruit, dragon fruit is rich in nutrition and unique in function. fiber. Dragon fruit is a plant that was introduced to Taiwan from Southeast Asia, and then improved and introduced from Taiwan to Hainan Province, Guangxi, Guangdong and other places in the south of the mainland. The cultivation history of dragon fruit in my country is relatively short, and the cultivation area is still very...
