Problems solved by technology

[0003] The traditional flue-cured tobacco water and fertilizer management method has low water and fertilizer utilization rate and poor coordination of water and fertilizer, which seriously affects the yield and quality of tobacco leaves. If things go on like this, it is difficult to ensure the green and sustainable development of tobacco
Therefore, the tobacco industry is also vigorously promoting the integration of water and fertilizer technology. Related patents include "an automatic fertilization and irrigation device for the integration of water and fertilizer in tobacco fields (CN205623212)", "an automatic irrigation device for the integration of water and fertilizer in flue-cured tobacco (CN 206472491)", etc. It mainly focuses on the equipment, devices, and management systems of water and fertilizer integration. There is no integrated water and fertilizer planting technology for Yunnan's ecological climate conditions and the law of water and fertilizer demand for mountain tobacco.

Abstract

The invention relates to a tobacco, water and fertilizer integrated dynamic nutrition management method suitable for Yunnan mountainous regions. The method comprises steps as follows: 7 days after transplantation, water and fertilizer integrated equipment is adopted to perform pure water drop irrigation with application amount being 4-5 m<3> / mu; 15 days after transplantation, organic water-solublefertilizer with application amount being 3-5 kg / mu is applied to 5-6 m<3> / mu water for drop irrigation; 25 days after transplantation, the organic water-soluble fertilizer with application amount being 5-7 kg / mu is applied to 5-6 m<3> / mu water for drop irrigation; 35 days after transplantation, the organic water-soluble fertilizer with application amount being 7-10 kg / mu is applied to 6-8 m<3> / muwater for drop irrigation; 45 days after transplantation, the organic water-soluble fertilizer with application amount being 15-18 kg / mu is applied to 8-15 m<3> / mu water for drop irrigation; 60 daysafter transplantation, the organic water-soluble fertilizer with application amount being 3-6 kg / mu and potassium sulfate with application amount being 0-2.88 kg / mu are applied to 6-8 m<3> / mu water for drop irrigation. With adoption of the method, water and fertilizer utilization rate can be effectively increased, nitrogen reducing amount reaches 15%-20%, tobacco quality is improved, the purposesof saving water and fertilizer, reducing cost and improving quality are achieved, and one new method is provided for scientific tobacco planting.

Description

technical field [0001] The invention relates to the technical field of tobacco nutrition management, in particular to a method suitable for integrated dynamic nutrition management of tobacco, water and fertilizer in mountainous areas of Yunnan. Background technique [0002] Water and nutrients are the essential material basis for crop growth, and they are also the main factors limiting crop yield and quality. Tobacco is a water-loving crop, the water content in the plant is 70%-80%, and the water content in the leaves is 90%-93%. Fertilizers or other nutrients in the soil can only be absorbed and utilized by tobacco plants under suitable water conditions. Insufficient water restricts the function of nutrients. Similarly, insufficient nutrients also restricts water absorption. Under different water potential conditions, the amount of fertilizer applied The level of water directly affects the absorption and utilization of water and nutrients by crops. [0003] Traditional fl...
