Embodiment 1
[0026] Choose a tobacco field or a new stubble field that has been cropped for 3 years, and apply base fertilizer per mu: fermented cake fertilizer 30kg, superphosphate 18.6kg, calcium ammonium nitrate 4kg, potassium sulfate 6.5kg, potassium nitrate 8.1kg, and fungicides and microorganisms can be added at the same time agent, mixed evenly, and applied to the bottom of the ridge when the ridges are raised, with a ridge spacing of 1.2m.
[0027] Before transplanting the tobacco seedlings, make preparations before planting, arrange the tobacco ridges, spray herbicides, dig holes, the distance between the plants is 50cm, the surface of the holes is 30cm, and the depth of the holes is more than 20cm. Uniform and strong seedlings, ensure that most of the tobacco stems are buried in the moisture soil, avoid the heart leaves from being buried in the soil, the tobacco stems should be upright, the tobacco roots should be stretched, and the root water should be poured. Drip irrigation sy...

Abstract
The invention discloses a fertilizer, water and pesticide integrated management method for tobacco. The method is characterized in that all organic fertilizers and 60% of inorganic nitrogen, phosphorus and potassium are applied to ridge bottoms during ridge forming as basal fertilizers; 40% of inorganic phosphate fertilizer, 20% of inorganic nitrogen fertilizer and 10% of inorganic potassium fertilizer are subjected to pit application during transplanting; the rest nitrogen-potassium fertilizers and pesticides for preventing plant diseases and insect pests are applied through a drip irrigationsystem, drip-irrigation fertilizer and pesticide application is carried out once 15d after tobacco seedling transplanting, and the irrigation volume is 3m<3>/mu; drip-irrigation fertilizer application is carried out once at a resettling stage, and the irrigation volume is 10m<3>/mu; drip-irrigation fertilizer application is carried out once at a vigorous growth stage, and the irrigation volume is15m<3>/mu; and drip-irrigation fertilizer application is carried out once after tip pruning, and the irrigation volume is 5m<3>/mu. The method has the advantages that the requirements of tobacco production on water and fertilizers are taken into account comprehensively, disease and insect pest control also gains attention, integrated management on water, fertilizers and pesticides for tobacco production is achieved by dint of a water and fertilizer integrated system, the labor intensity is lowered, the increase of water and fertilizer utilization efficiency is facilitated, the content of potassium in tobacco leaves is increased, the disease incidence of plant diseases and insect pests is lowered, and the yield and quality of the tobacco leaves are improved.
Description
technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to an integrated management method of tobacco fertilizer, water and medicine. Background technique [0002] Tobacco is a crop that needs a lot of water and fertilizer. It needs 400-600mm of water during the whole growth period. For every 1000kg of flue-cured tobacco leaves produced, it needs 22kg of nitrogen, 11.6kg of phosphorus pentoxide, and 48kg of potassium oxide. [0003] Moisture is the basis for tobacco growth and quality formation. Tobacco field moisture management is carried out according to the moisture demand characteristics of tobacco at different growth stages to meet the moisture demand of tobacco leaves in a timely, quantitative and effective manner, which can promote leaf expansion and increase material accumulation. Ensure that the tobacco leaves are fully mature and lay the foundation for the production of high-quality tobacco leaves. Flue-cured t...
