Problems solved by technology

At present, most of the tea gardens in my country are affected by various factors such as poor foundation of garden construction, single fertilization, and poor management, resulting in a decline in tea output and quality.
In particular, the extensive use of pesticides and chemical fertilizers has caused problems such as pesticide residues, soil compaction, and heavy metal pollution, which have a serious impact on product quality

Embodiment 1

[0032] On December 2, a tea garden with a tea tree seedling age of 10 years was selected, and biochar was applied to the soil at a depth of 10 cm directly below the outer edge of the tea tree crown. Material charcoal 1000kg, at the same time, apply 1000kg of green manure and 500kg of peat in concentrated strips, fully mix the biochar with the soil, apply green manure and peat to the soil in layers, cover the soil layer by layer, so that the soil and fertilizer are blended, and finally cover the top with a thin layer of soil.

Embodiment 2

[0034] On December 6th, a tea garden with 14-year-old tea tree seedlings was selected, and biochar was applied to the soil at a depth of 15 cm directly below the outer edge of the tea tree crown. Material charcoal 1200kg, at the same time, apply 1200kg of grass fertilizer and 550kg of peat in concentrated strips, fully mix the biochar with the soil, apply the grass fertilizer and peat into the soil layer by layer, cover the soil layer by layer, so that the soil and fertilizer are blended, and finally on the top Cover with a thin layer of soil.

Embodiment 3

[0036] On December 10, a tea garden with 19-year-old tea tree seedlings was selected, and biochar was applied to the soil at a depth of 20 cm directly below the outer edge of the tea tree crown. Material charcoal 1500kg, at the same time, apply 1500kg of straw and 650kg of peat in concentrated strips, fully mix the biomass charcoal with the soil, apply the straw and peat to the soil in layers, cover the soil layer by layer, so that the soil and fertilizer are blended, and finally cover the top with a thin layer of soil.

Abstract

The invention relates to the technical field of biomass charcoal utilization, and provides a method for improving tea garden soil health by using biomass charcoal. The method comprises the following steps: in an adult tea garden with tea tree seedling age of 10 years or more, applying biomass charcoal, organic fertilizer and peat into soil with the depth of 10-30cm under the outer edge of a tea tree crown in the first ten days and the middle ten days of December. According to the method, after the tea garden production is finished, the biomass charcoal, the organic fertilizer and the peat are applied, so that not only can the soil fertility be effectively improved, but also the pesticide residues and the heavy metal content in the soil can be reduced, and the health condition of the soil is comprehensively improved. Meanwhile, agricultural and forestry waste resources are effectively treated, harmlessness, reduction and recycling of solid waste are achieved, the utilization range of the biomass charcoal is widened, the industrial chain is prolonged, and development of circular economy is facilitated.

Description

technical field [0001] The invention relates to the technical field of biomass charcoal utilization, in particular to a method for improving the health of tea garden soil by using biomass charcoal. Background technique [0002] Tea trees are commonly found in the mountainous areas of the provinces south of the Yangtze River in China. They are small trees with large leaves, often more than 10 cm long. After extensive cultivation for a long time, the hair cover and leaf shape have changed greatly. Tea contains a variety of beneficial ingredients and has health benefits. [0003] Tea is a traditional drink in my country with a long history. In recent years, tea has moved from China to the world, and has become an important variety in the world's beverage market, which is one-third of the world. What follows is the increasingly fierce competition in the tea market. At present, most of the tea gardens in my country are affected by various factors such as poor foundation of gard...
