Buried application medical fertilizer for controlling cotton diseases and method for producing the same

Abstract

The invention relates to a buried application type medical fertilizer for preventing and treating cotton diseases and insect pests. The buried application type medical fertilizer is prepared from the following raw materials in weight percentage: 60 to 64.5 percent of oil cake, 1 to 2.5 percent of Xinkehuangku, 1.0 to 1.5 percent of zinc-boron-potass-calcium amino acid, 4 to 5 percent of 3 percent isazofos granules and 28 to 32 percent of 48 percent composite fertilizer. The production method comprises the following steps: the Xinkehuangku and zinc-boron-potass-calcium amino acid liquid are diluted in water, are put to a stirrer, are evenly mixed and are added with the oil cake; the stirrer is started up, the mixture is evenly mixed and is discharged and dried; and dried oil cake powder containing the Xinkehuangku and the zinc-boron-potass-calcium amino acid and the 3 percent isazofos and the 48 percent composite fertilizer are mixed in the stirrer and are evenly mixed and stirred to form the buried application type medical fertilizer. The buried application type medical fertilizer for preventing and treating the cotton diseases and insect pests has average relative preventing rate of fusarium wilt and greensickness of cotton of 83.7 percent; and the insect pest of the cotton is controlled within the range allowed by an economic threshold value.

Description

technical field [0001] The invention relates to a buried-applied medicinal fertilizer for preventing and controlling cotton diseases and insect pests and a production method thereof. Background technique [0002] Due to the popularization of insect-resistant cotton, cotton fusarium wilt has spread more and more widely in the cotton area of ​​the country, and the occurrence has become more and more serious. The disease resistance is not as good as that of non-insect-resistant cotton varieties. In terms of the occurrence of cotton pests, the Bt gene-transferred insect-resistant cotton is generally only effective against pests such as cotton bollworm, red bollworm, corn borer, bridge-builder, and diamond drill, and the insecticidal spectrum is not wide. Pests such as thrips, cotton spider mites, Spodoptera litura, and Beet Spodoptera have no control effect. The main pests have now risen to be the main pests, and the damage is very serious. For this reason, a large amount of p...

Problems solved by technology

In terms of the occurrence of cotton pests, the Bt gene-transferred insect-resistant cotton is generally only effective against pests such as cotton bollworm, red bollworm, corn borer, bridge-builder, and diamond drill, and the insecticidal spectrum is not wide. Pests such as thrips, cotton spider mites, Spodoptera litura, and Beet Spodoptera have no control effect. The main pests have now risen to be the main pests, and the damage is very serious. For this reason, a large amount of pesticides must be sprayed and controlled, which is caused by the defects of insect-resistant cotton.
