Abstract

The invention discloses a tobacco straw compound fertilizer for slowly releasing drought stress. The tobacco straw compound fertilizer is prepared from the following components in parts by weight: 1000 parts of dry straws, 2500 parts of biogas slurry, 200-300 parts of urea, 50-70 parts of monopotassium phosphate, 80-110 parts of boric acid, 60-80 parts of chromium trichloride, 50-80 parts of manganese chloride, 100-120 parts of zinc sulfate, 16-25 parts of polyaspartic acid, 15-20 parts of trichodermaspp, 9-15 parts of micromonospora and 20-30 parts of polyangium cellulosum. The tobacco straw compound fertilizer is prepared through the following steps of: selecting biogas slurry which can normally generate methane; implementing aerobic fermentation; implementing anaerobic fermentation; adding boric acid, chromium trichloride, manganese chloride, zinc sulfate and polyaspartic acid in a fermentation tank to form a mixture; evenly mixing the mixture; bagging and packaging the mixture.

Description

technical field

[0001] The invention relates to a tobacco fertilizer, in particular to a tobacco stalk compound fertilizer for slow release of drought stress. Background technique

[0002] Tobacco likes a warm and humid climate, and has high requirements for moisture throughout the growth period. Only under the ecological conditions with suitable moisture can the life activities of tobacco go smoothly; Due to the lack of necessary irrigation conditions, there are always some tobacco areas every year due to soil drought, which affects the normal growth and development of tobacco plants, resulting in a reduction in the yield and quality of tobacco leaves.

[0003] Long-term single application of chemical fertilizers will cause long-term problems such as soil compaction, nutrient imbalance, and poor physical properties, and the production capacity will drop significantly, and the fertilizer efficiency of organic fertilizers will be slow. Burn directly in the field to avoid aff...
