Special seaweed bio-fertilizer for tobacco and special fertilizing device

Abstract

The invention discloses a seaweed biological fertilizer special for tobacco. The seaweed biological fertilizer is prepared from 26-35 parts of rapeseed cake fertilizer, 3-6 parts of seaweed leavening with biological activity, 18-22 parts of nitrogen fertilizer, 13-20 parts of phosphate fertilizer, 16-22 parts of potash fertilizer, 2-3 parts of silane coupling agent, 1-2 parts of polyaspartic acid, 0.5-2.5 parts of medium trace elements and 0.5-1 part of calcined shell powder. The seaweed bio-fertilizer is crushed and mixed into a water fertilizer, and the water fertilizer is fertilized to a tobacco root system part through a special fertilization device. The bio-fertilizer is added with macronutrient elements, medium and micronutrient elements and active seaweed components required by tobacco growth, so that on one hand, the fertility of soil can be improved, cultivated land can be nursed, on the other hand, the stress resistance of tobacco can be improved, plant diseases and insect pests can be reduced, and the application of pesticides can be reduced; the yield and quality of tobaccos and the improvement of cultivated land quality can be guaranteed, and meanwhile, the special fertilizing device is matched, so that the remarkable effect of reducing labor and cost can be achieved.

Description

technical field [0001] The invention relates to the field of fermentation treatment technical equipment; in particular, it relates to a special seaweed biological fertilizer for tobacco and a special fertilization device. Background technique [0002] Tobacco, as an important economic crop in our country, can produce high economic benefits every year, but with successive years of crop rotation, the quality of arable land has been seriously damaged. Therefore, the existing tobacco planting arable land needs to be supplemented with nutrients in time, and now Most of the methods of fertilization are used to supplement the nutrients of the cultivated land, but the problem in the prior art is that the types of fertilizers currently used are relatively single. Although the application of organic fertilizers is emphasized, the application of trace elements in the fertilizers is still lacking. There is also no addition of some active ingredients to ensure soil fertility. [0003] I...

Problems solved by technology

[0002] Tobacco, as an important economic crop in our country, can produce high economic benefits every year, but with successive years of crop rotation, the quality of arable land has been seriously damaged. Therefore, the existing tobacco planting arable land needs to be supplemented with nutrients in time, and now Most of the methods of fertilization are used to supplement the nutrients of the cultivated land, but the problem in the prior art is that the types of fertilizers currently used are relatively single. Although the application of organic fertilizers is emphasized, the application of trace elements in the fertilizers is still lacking. No active ingredients are added to ensure soil fertility

[0003] In addition, the current fertilization device only involves single rotary tillage and fertilization to form ridges, and the roots of tobacco are usually deeply rooted. The method of surface ridge fertilization can only achieve shallow fertilization, and the fertilizer is not directly sent to the roots for root absorption. And if the depth of ridging is deep, it may damage the root system of tobacco roots, and the gain outweighs the gain; in addition, in the prior art, the fertilization of the deeper root system can also be realized by laying a deeper drip irrigation device in the soil, but This kind of technical solution has a large amount of engineering, and the entire cultivated land soil almost needs to be refurbished, which is time-consuming and labor-intensive.
