Special controlled release formula fertilizer for oil palm

Abstract

The invention relates to a special controlled release formula fertilizer for oil palm, belonging to the technical field of slow / controlled release fertilizers. The special controlled release formula fertilizer is characterized by comprising the following raw material components in parts by weight: 50-100 parts of 60-day reaction film-forming polymer coated urea, 100-150 parts of 120-day reaction film-forming polymer coated urea, 50-150 parts of 120-day reaction film-forming potassium sulphate, 50-150 parts of urea, 50-250 parts of diammonium phosphate, 150-250 parts of potassium sulphate, 10-30 parts of magnesium sulfate, 1-10 parts of zinc sulfate and 1-20 parts of borax. The special controlled release formula fertilizer has the beneficial effects of being high in fertilizer efficiency, complete in fertilizer efficiency, releasing nitrogen, phosphorus and potassium nutrients as required, reducing the fertilizer loss, protecting the ecological environment, being long in fertilizer efficiency period, reducing the labor force, being capable of greatly reducing the fertilizing times, and realizing the reduction of the fertilizing times, thereby reducing the labor cost and increasing the income.

Description

technical field [0001] The invention relates to a special controlled release formula fertilizer for oil palm and belongs to the technical field of slow / controlled release fertilizers. Background technique [0002] oil palm ( Elaeis guineensis Jacq.) is the world's number one oil crop. Oil palm, also known as oil palm, is a perennial plant of the genus Elaeis in the family Palmaceae, native to tropical Africa. The oil palm will be put into production 2-3 years after planting, with an economic life of 25-30 years and a natural life of up to 100 years. The global average crude oil (CPO) output per unit area can reach 3.7 t / hm 2 .yr -1 , is 8 times, 4 times and 14 times the yield per unit area of ​​soybean, rapeseed and peanut, and is the oil crop with the highest production efficiency in the world. Asia, Africa and Latin America between N 15°. [0003] my country is a country with a large population and consumes a lot of vegetable oil. However, due to problems such as "gr...

AI Technical Summary

Problems solved by technology

[0007] Aiming at the deficiencies of the prior art, the present invention provides a special controlled-release formula fertilizer for oil palm and its preparation method, using three different release periods to react film-forming polymerization According to the nutrient release characteristics of the material-coated controlled-release fertilizer, according to the nutrient absorption law of oil palm, a single controlled-release fertilizer and some quick-acting fertilizers with a specific coating amount and different release time periods are compounded to obtain a special controlled-release formula fertilizer for oil palm. , can continuously and synchronously supply the nutrients needed by oil palm, improve the fertilizer utilization rate, and avoid environmental pollution problems. The added medium and trace elements magnesium, zinc and boron can improve the quality of oil palm and plant stress resistance, and increase the benefits of farmers , and carried out application tests, and achieved good results
