Embodiment 1

[0032] Example 1: Nutrient synchronous controlled-release fertilizer dedicated to hot-growing sweet waxy corn. The ratio of total nutrients: nitrogen, phosphorus pentoxide, and potassium oxide is 20:10:12, both in mass percentage. The raw material components are as follows: The raw material components characterized in their parts by weight are: ordinary urea (46% N content) 160kg, controlled release urea (30-60 days, N content 43%, produced and sold by China BlueChemical) 80kg, controlled release Urea (60-90 days, N content 43%, produced and sold by China BlueChemicals) 160kg, monoammonium phosphate (N content 11%, P 2 o 5 Content 44%) 230 kg and potassium chloride (K 2 O content 60%) 200 kg, zinc sulfate 3kg. Mix the materials mechanically and pack them into bags.

Embodiment 2

[0033] Example 2: Nutrient synchronous controlled-release fertilizer dedicated to hot-growing sweet waxy corn. The proportions of total nutrients: nitrogen, phosphorus pentoxide, and potassium oxide are 22:9:15, all in mass percent. The raw material components are as follows:

[0034] Ordinary urea (N content 46%) 150 kg, controlled-release urea (30-60 days, N content 43%, produced and sold by China BlueChemicals) 100kg, controlled-release urea (60-90 days, N content 43%, produced and sold by China BlueChemicals) ) 200kg, monoammonium phosphate (N content 11%, P 2 o 5 Content 44%) 270kg and potassium sulfate (K 2 O content 50%) 300kg, zinc sulfate 4kg. Mix the materials mechanically and pack them into bags.

Embodiment 3

[0035] Example 3: Nutrient synchronous controlled-release fertilizer dedicated to hot-growing sweet waxy corn. The ratios of total nutrients: nitrogen, phosphorus pentoxide, and potassium oxide are 15:8:10, all in mass percent. The raw material components are as follows:

[0036] Ordinary urea (N content 46%) 128 kg, controlled-release urea (30-60 days, N content 43%, produced and sold by China BlueChemicals) 64kg, controlled-release urea (60-90 days, N content 43%, produced and sold by China BlueChemicals) ) 128kg, diammonium phosphate (N content 18%, P 2 o 5 Content 46%) 175kg and potassium chloride (K 2 O content 60%) 170kg, zinc sulfate 2 kg. Mix the materials mechanically and pack them into bags.

Abstract

The invention relates to a special nutrient synchronous controlled-release fertilizer for thermal plant sweet waxy maizes. The special nutrient synchronous controlled-release fertilizer is characterized by comprising the following raw material components in parts by weight: 15-25 parts of nitrogen fertilizer, 8-12 parts of phosphate fertilizer, 10-20 parts of potassium fertilizer and 0.1-0.5 part of zinc sulfate; the nitrogen fertilizer is composed of common urea, reaction filming coated urea released for 30-60 days, and reaction filming coated urea released for 60-90 days; the reaction filming coated urea released for 30-60 days has a nutrient release period of 30-60 days; the reaction filming coated urea released for 60-90 days has a nutrient release period of 60-90 days; the phosphate fertilizer is monoammonium phosphate or diammonium phosphate. The potassium fertilizer is potassium chloride or potassium sulfate. The special nutrient synchronous controlled-release fertilizer has the following excellent effects: 1, obviously increasing the production and the effect; 2, improving the quality of maizes; and 3, saving the time and labor.

Description

[0001] technical field [0002] The invention relates to a nutrient synchronous controlled-release fertilizer specially used for hot cropping sweet waxy corn. Background technique [0003] In recent years, with the improvement of people's living standards and food culture, the diversity of corn varieties has also been favored by consumers, and the market for fresh food products of tropical sweet waxy corn is in short supply. At present, my country's fruit and vegetable corn is in a period of rapid development, and the hot crop planting season has developed from winter planting to spring, summer, and autumn planting, and its development prospects are good. [0004] However, at present, quick-acting fertilizers are mainly used for fertilization of sweet waxy corn in hot cropping, and there is no special fertilizer. Due to the long rainy season and heavy rainfall in tropical areas, fertilizer nutrients, especially nitrogen fertilizers, dissolve quickly in the soil and are easy ...
