Application method of organic nitrogen fertilizer and inorganic nitrogen fertilizer in tea garden

Abstract

The invention discloses an application method of organic nitrogen fertilizer and inorganic nitrogen fertilizer in a tea garden, and belongs to the technical field of agriculture. The method comprises the following steps that the organic nitrogen fertilizer and the inorganic nitrogen fertilizer are selected, and when the organic nitrogen fertilizer is converted into pure nitrogen, the annual total amount of the pure nitrogen ranges from 10 kg to 15 kg per mu; when the inorganic nitrogen fertilizer is converted into the pure nitrogen, the annual total amount of the pure nitrogen ranges from 10 kg to 15 kg per mu; the fertilizer is applied before spring tea is picked, in May and in September respectively, wherein 4-6 kg of inorganic nitrogen fertilizer per mu is used before the spring tea is picked, 5-7.5 kg of organic nitrogen fertilizer per mu and 3-4.5 kg of inorganic nitrogen fertilizer per mu are used in May, and 5-7.5 kg of organic nitrogen fertilizer per mu and 3-4.5 kg of inorganic nitrogen fertilizer per mu are used in September. According to the application method of the organic nitrogen fertilizer and the inorganic nitrogen fertilizer in the tea garden, the utilization efficiency of the nitrogen fertilizer is increased, the tea safety quality is improved, and the environmental pollution is effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a method for applying organic nitrogen fertilizer and inorganic nitrogen fertilizer in tea gardens. Background technique [0002] In the process of tea production, great attention is paid to the application of nitrogen fertilizer, which has achieved obvious economic benefits. However, with the increase in the amount of nitrogen fertilizer used in tea gardens, the input is not proportional to the output, the soil quality is degraded, the emission of greenhouse gases is large, and the environment is damaged. At present, excessive use of nitrogen fertilizers, low nitrogen use efficiency, and serious losses are common in tea gardens in my country, which have a serious impact on my country's environment, tea quality, safety of production areas, and sustainable development of the tea industry. [0003] In recent years, the Chinese government has realized the seriousness...

Problems solved by technology

[0004] Organic fertilizer has the characteristics of comprehensive nutrition, long fertilizer effect, and improvement of soil physical and chemical properties, but its low effective nutrient, slow release and other shortcomings cannot meet the requirements of large fertilizer demand and fast absorption in the growing season of tea trees, while inorganic fertilizer has quick effect It just makes up for the shortage of organic fertilizers, so as to improve the soil and meet the fertilizer absorption characteristics of tea trees.

[0005] At present, there are two main problems in the fertilization of tea gardens: ① The amount of nitrogen fertilizer is too large, mainly inorganic nitrogen fertilizer, and less or no organic fertilizer is applied.

The resulting consequences are environmental pollution, improper use of organic fertilizers, decline in tea quality and safety, etc.
