Problems solved by technology

[0005] In the traditional crop planting technology, crop fertilization and pesticide application are carried out separately, resulting in high labor intensity and many labor times for farmers
Moreover, the management of fertilization and the prevention and control of pesticides are not targeted, which can easily lead to blind fertilization and pesticides, resulting in unbalanced fertilization, poor pest control, and poor disease control.

Embodiment 1

[0033] Embodiment 1 Research on compound performance of imidacloprid and fludioxonil

[0034] Experimental method: indoor toxicology test

[0035] LD of tested drugs against wheat field aphids 50 Value test: Take the drug to be tested in each group, immerse the wheat aphids in the drug solution for 10 seconds, absorb the excess drug solution with filter paper, transfer the tested worms to rearing under normal conditions, repeat 4 times for each treatment, and 20 worms were soaked for the second time, and the treatment without pesticide was set as the control.

[0036] The EC of the drug to be tested against wheat sheath blight 50 Value test: Take each group of the drug to be tested, spray the drug solution on the potted wheat plants, keep them all wet, and wait for the drug solution to dry naturally for later use. Each treatment is 1 pot, repeated 4 times, and the treatment without drug is set. as comparison.

Abstract

The invention belongs to the technical field of fertilizers, and discloses a pesticide fertilizer slow release preparation, as well as a preparation method and an application method thereof. The pesticide fertilizer preparation comprises 0.01-10 percent of imidacloprid, 0.001-0.5 percent of fludioxonil, 10-80 percent of amino acids, 0.1-5 percent of slow release materials, 0.5-4 percent of a dispersing auxiliary, and the balance of fillers. The pesticide fertilizer slow release preparation has the triple effects of pest killing, anti virus and fertilizing, and is capable of making crops resistant to pests and diseases and providing supplementary nutrients for crop growth; the lasting period of the effects of pesticide and fertilizer is extended; the utilization and use effects of pesticide and fertilizer are improved; effects of pesticide and fertilizer are strengthened; crop yield is remarkably increased.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and relates to a slow-release preparation of medicinal fertilizers, a preparation method and an application method thereof. Background technique [0002] Amino acid is the basic unit of protein. It endows protein with a specific molecular structure and makes its molecules biochemically active, which can be directly absorbed by various organs of plants. Proteins are important active molecules in organisms, including enzymes that catalyze metabolism. During the growth and development of plants, various amino acids are needed as nutrients to synthesize their own proteins. However, the soil often cannot meet the needs of crops independently, so it is particularly important to apply amino acids artificially. [0003] Crop pests are also one of the important factors affecting crop yield and quality. For crop pests, chemical insecticides are currently mainly used for control. Imidacloprid is a s...
