AI Technical Summary

Problems solved by technology

If the amount of application is too large at one time, it will easily cause fertilizer loss, cause waste, and cause groundwater pollution and eutrophication of rivers and lakes.
If a small amount of fertilization is used many times, it will increase the labor intensity and labor cost of farmers

Embodiment 1

[0043] Embodiment 1: Special controlled-release fertilizer for bananas, total nutrient: nitrogen, phosphorus pentoxide, potassium oxide content are respectively 18%, 8%, 18%, mass percentage. The raw material components are as follows:

[0044] 6% thermoplastic resin coated urea 40kg

[0045] 7% thermoplastic resin coated urea 60kg

[0046] Sulfur coated urea 260kg

[0047] Potassium sulfate compound fertilizer 300kg

[0048] Potassium sulfate 275kg

[0049] Diammonium phosphate 55kg

[0050] Zinc sulfate 5kg

[0051] Borax 5kg.

[0052] Preparation:

[0053] Put the above-mentioned raw materials together into a blender and stir for 8 minutes, and mix well to get the product. Then the mixed fertilizer is sent to the metering and packaging machine for metering and packaging.

Abstract

The invention relates to a special controlled release fertilizer for banana and a preparation method thereof and belongs to the technical field of sustained release fertilizer and controlled release fertilizer. According to the rule of the fertilizer requirement of the banana, the invention remixes 6 percent and 7 percent thermoplastic resin coated urea, sulfur coated urea, potassium sulfate complex fertilizer, the potassium sulfate, diammonium phosphate, zinc sulfate and borax exactly to form the special controlled release fertilizer for banana. The nutrient release rule of the controlled release fertilizer is in accordance with the nutrition absorption rule of the banana, which improves the fertilizer absorption and utilization rate and reduces the cost of the controlled release fertilizer, and the effect of production increase is good.

Description

technical field [0001] The invention relates to a special controlled-release fertilizer for crops produced by coated sulfur and coated thermoplastic resin, in particular to a special controlled-release fertilizer for bananas and a manufacturing method thereof, belonging to the technical field of slow / controlled release fertilizers. Background technique [0002] Banana is one of the main fruits in my country. In 2002, my country's banana planting area was 248,000 hectares, with a total output of 5.557 million tons and an export of 40,000 tons with a value of 18.817 million US dollars. Banana is rich in nutrition and convenient to eat. It can be eaten as a fruit or as a staple food. Bananas also have medicinal value. my country is the most populous country in the world and has a huge potential consumer market. Experts predict that with the development of my country's national economy and the improvement of people's living standards, my country's banana production will contin...
