Embodiment Construction

[0007] Technical scheme of the present invention is as follows:

[0008] Controlled-release fertilizer for disease-preventing cotton in Xinjiang, the composition of raw materials is as follows:

[0009] Humic acid-coated urea 50-150 parts,

[0010] Sulfur plus polymer coated urea 150-250 parts,

[0011] Sulfur-coated urea 50-220 parts,

[0012] Potassium chloride compound fertilizer 350-550 parts,

[0013] 8-12 parts of zinc sulfate,

[0014] 5-10 parts of boric acid,

[0015] 20-25 copies of thiophanate-methyl preparation,

[0016] 30-35 parts of carbendazim preparation,

[0017] Mancozeb preparation 20 to 30 parts.

[0018] The humic acid-coated urea is sprayed with a layer of binder on the outside of the granular urea, and then sprayed with a layer of air-dried and pulverized weathered coal. After solidification, the above process is repeated until the binder accounts for 1% of the mass of the granular urea. , weathered coal accounts for 5% of the mass of granular u...

Abstract

The invention relates to a disease-preventing type controlled release fertilizer special for Xinjiang cotton, and preparation and application thereof. Humic acid coated urea, sulfur macromolecular polymer coated urea, sulfur coated urea, a potassium chloride composite fertilizer and a trace element fertilizer which serve as raw materials are mixed with granular pesticide precisely and then coordinates mutually, so that release and proportion of the nutrients are suitable for the nutrient condition of the soil in the main producing area of the Xinjiang cotton and absorption requirement of the cotton, and main diseases such as cotton damping off, epidemic disease, anthracnose, fusarium wilt and the like can be prevented and treated. The disease-preventing type controlled release fertilizer special for the Xinjiang cotton is applied at one step during planting or transplanting of the cotton, so labor and time are saved, and disease-preventing and yield-increasing effects are good.

Description

technical field [0001] The invention relates to a special controlled-release fertilizer, in particular to a disease-preventing Xinjiang cotton special controlled-release fertilizer and its preparation method and application, belonging to the technical field of production and application of controlled-release fertilizers. Background technique [0002] As an important commodity cotton base in the country, Xinjiang's total cotton output accounts for about 40% of the country's total. In 2010, Xinjiang's cotton planting area was 14.2 million mu, with a total output of 1.5 million tons. Xinjiang has ranked first in the country for 15 consecutive years in seven indicators including planting area, total output, and average yield per mu. [0003] In recent years, the popularization of transgenic insect-resistant cotton has effectively controlled the harm of cotton bollworm and other pests. However, the genetically modified cotton has poor resistance to diseases such as blight and fu...
