Sustained-release preparation of sugarcane field insecticidal nutrient fertilizer and preparation method thereof

Abstract

The invention belongs to the technical field of fertilizers, and discloses a slow-release preparation of insecticidal nutrient fertilizer for sugarcane fields and a preparation method thereof. The medicinal fertilizer slow-release preparation, in terms of mass percentage, includes the following components: 0.001% to 5% clothianidin, 10% to 60% fertilizer active ingredient 1, 0.1% to 15% fertilizer active ingredient 2, 0.01% % to 10% of the active ingredient three of the fertilizer, 0.001% to 1% of the active ingredient four of the fertilizer, 0.1% to 30% of the coating material and the rest of the filler; the first active ingredient of the fertilizer is nitrogen, phosphorus and potassium; the The active ingredient 2 of the fertilizer is one or a mixture of two or more of calcium, magnesium, silicon or sulfur; the active ingredient 3 of the fertilizer is a mixture of one or more of boron, zinc, manganese, molybdenum or copper; the fertilizer is effective The fourth ingredient is selenium. The drug fertilizer slow-release preparation improves the utilization rate and application effect of pesticides and fertilizers, has a significant effect of increasing production and sugar, and saves labor at the same time.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a slow-release preparation of insecticidal nutrient fertilizer for sugarcane fields and a preparation method thereof. Background technique [0002] Sugarcane is an annual or perennial perennial tropical and subtropical herbaceous plant. It is an important raw material for the manufacture of sucrose, with a wide planting area and high economic value. The sugarcane stalks are upright, thick and juicy, often covered with white powder on the surface, the leaves are alternate, with small sharp teeth on the edges, and the flower spikes are compound racemes. Sugarcane tastes sweet, astringent, mild in nature, and non-toxic. It is rich in sugar, water, multivitamins, protein, calcium, iron and other substances. It has the effect of clearing away heat and promoting body fluid, and is very popular among people. [0003] The uptake of fertilizers by sugarcane as it grows, a...

Problems solved by technology

Sugarcane aphids cause sugarcane leaves to turn yellow and wither. At the same time, aphids also excrete honeydew and splash on the leaves, causing soot disease, reducing photosynthesis, and affecting sugarcane yield and sugar quality.

In recent years, highly toxic pesticides such as carbofuran, phorate, methylisothion, terbuthion, etc. are generally used for sugarcane insect control, which are highly toxic to humans and animals and have large residues. The country has restricted their use or banned them.

[0005] In the traditional sugarcane planting technology, the application of fertilizers and insecticides are separated. Generally, three times of fertilization and two to three times of insecticides are required, resulting in high labor intensity and many labor times for farmers.

Moreover, sugarcane fertilization management and pesticide application control are not targeted, which may easily lead to blind fertilization and pesticide application, resulting in unbalanced fertilization and poor pest control effect
