preparation example Construction

[0058] The present invention also provides the preparation method of above-mentioned medicine fertilizer, for

[0059] Making insecticides and fungicides into pesticide suspensions;

[0060] Granulate the fertilizer, dry, cool, and sieve to make fertilizer granules;

[0061] The pesticide suspension and the binder are sprayed and coated on the fertilizer granules, and mixed evenly to make the fertilizer granules.

[0062] Among them, in the process of making insecticides and fungicides into pesticide suspensions, insecticides and fungicides need to be mixed with water, dispersants and stabilizers. When preparing fertilizer granules, fertilizers with large amounts of elements such as nitrogen, phosphate, and potash fertilizers need to be mixed with fillers and loss control agents before being granulated, followed by drying, cooling, and screening to make fertilizer granules. Therefore, in some embodiments, the preparation method of the medicinal fertilizer of the present inve...

Abstract

The invention relates to the field of fertilizers, and discloses a special multi-resistance drug fertilizer for super rice and a preparation method thereof. The drug fertilizer disclosed by the invention comprises an insecticide, a bactericide and a fertilizer. In the drug fertilizer disclosed by the invention, the insecticide and bactericide are organically combined according to the rice nutrition characteristics, the soil fertility conditions and the rice pest and disease damage occurrence characteristics; in cooperation with certain amount of nutrient element fertilizer, the fertilizer drugs are combined and interact for synergism; nutrient elements are effectively supplemented while enhancing the rice resistance to pest and disease damage, the needs for nutrients of the rice are better met, the insecticidal and disease-resistant effects can be realized by once application of the fertilizer, and the manual work frequency is effectively reduced; moreover, the fertilizer is low-toxicity and safe to the environment and human and livestock, and is especially applicable to the super rice variety with high nutritional requirements and susceptible to pests and diseases. Experiments indicate that the drug fertilizer disclosed by the invention has the advantages of good insecticidal and disease-resistant effects, comprehensive nutrition, balanced and lasting nutrient supply and long lasting period; meanwhile, the labor intensity and cost in cultivation are reduced, the rural income is increased, and the labor is saved while the yield is increased; the fertilizer is energy-saving and efficient and safe and environment-friendly.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a special medicinal fertilizer for rice and a preparation method thereof, in particular to a special multi-resistant fertilizer for super rice and a preparation method thereof. Background technique [0002] Rice is one of the main food crops in the world. Nearly half of the world's population, including almost the entire population of East Asia and Southeast Asia, live on rice, and its production covers all continents except Antarctica. In the late last century, the average annual rice output in the world was about 400 billion kilograms, and the planting area was about 145 million hectares. Rice is also the most important food crop in my country. my country's rice sowing area accounts for 1 / 4 of the country's food crops, about 35 million hectares per year, while the output accounts for more than half. Regardless of the planting area and output, it ranks first in my country's food cro...
