Special organic and inorganic compound pesticide fertilizer for tobacco

Abstract

The invention discloses a special organic and inorganic compound pesticide fertilizer for tobacco. The special organic and inorganic compound pesticide fertilizer comprises the following components in parts by weight based on dry materials: 30-40 parts of organic active fertilizer, 12-20 parts of ammonium nitrate, 20-30 parts of calcium superphosphate, 16-32 parts of potassium nitrate, 5-10 parts of magnesium sulfate, 1-5 parts of zinc sulfate, 1-4 parts of sodium silicate, 0.1-1 part of borax, 0.02-0.1 part of ammonium molybdate, 0.5-1 part of insecticide, 0.5-1 part of bactericide and 0.5-1 part of coating agent. Compared with a conventional fertilizer, the special organic and inorganic compound pesticide fertilizer for the tobacco, produced according to the formula of the invention, has the advantages that 20-30 percent employees can be saved, the application of a pesticide is reduced, underground insects such as agrotis ypsilon and grubs, and root black rot can be controlled, a certain resistance is achieved for tobacco mosaic virus, the ratio of first-class tobacco is increased by 3.2-5.7 percent, and the output value is increased by 294.5-2512yuan / hm<2>.

[0002] Tobacco is an important economic crop in my country, with an annual planting area of ​​more than 1.4 million hectares and an output of more than 1.7 million tons. It is the world's largest producer of tobacco leaves. However, with the increase in continuous cropping years and the large input of chemical fertilizers, tobacco leaves The deterioration of the living environment, frequent occurrence of diseases and insect pests, and the quality of tobacco leaves are affected

[0003] At present, in the process of tobacco planting, great attention is also paid to the application of organic fertilizers. However, in actual operation, inorganic compound fertilizers and organic fertilizers are often packaged separately. During the application process, tobacco farmers mix and use them now, which wastes labor and mixes them. Uneven, also ignores the supplement of micronutrients and beneficial elements
