Soil improvement method of ecological tea garden

Abstract

The invention discloses a soil improvement method of an ecological tea garden and relates to the technical field of ecological tea garden establishment. The soil improvement method is characterized by including the steps of 1), land selection; 2), land regulation; 3), planting of leguminous green manure; 4), application of weathering coal; 5), application of organic fertilizer containing rhizobium; 6), adjustment of soil aid and alkali in the tea garden. The soil improvement method has the advantages that soil is well improved via placement and cultivation application of the weathering coal and planting of the leguminous green manure, the soil is fertile, fertility is long and stable, the soil is loosen, construction of the standardized ecological tea garden and development of tea industry are benefited, and higher market demand is met.

Description

Technical field:

[0001] The invention relates to the technical field of ecological tea garden construction, in particular to a soil improvement method for an ecological tea garden. Background technique:

[0002] Anhui Province is located in the middle and lower reaches of the Yangtze River. It has a mild and humid climate and four distinct seasons. The area of ​​mountains and hills accounts for more than 60% of the province. Especially the Huangshan Mountain in the south and the Dabie Mountain in the southwest are suitable for tea plantation. They are the main production and processing places for tea in our province. In the mid-1970s, the planting area of ​​tea gardens in our province was basically at the forefront of the country, reaching more than 1 million mu. In the 1990s, it accounted for 11.2% of the national tea garden area, reaching 1.78 million mu, second only to Zhejiang and Yunnan, ranking third in the country. , but after the 1990s, due to various reasons, the ar...

Embodiment 1

[0031] A method for building an ecological young tea garden, comprising the following steps:

[0032] a. In October 2013, a piece of mountain land to be reclaimed was selected in Tianzhu Mountain, Qianshan County, Anhui Province, with sufficient sunlight, close to water sources, no environmental pollution, and far away from industrial and living areas. This is the basis for building an ecological tea garden, and the water source is the mountain Spring water is used for automatic irrigation, away from pollution;

[0033] b. Land consolidation

[0034] Manually remove the larger shrubs and leave the smaller herbaceous plants. At the same time, the slopes are flattened to form a terraced field, and the terraced fields are placed for 2 years. During this period, the terraced fields are regularly turned over, and the terraced fields are turned over. Soil depth is 20-30cm;

[0035] c. Plant leguminous green manure

[0036] During the terrace placement period, a certain amount of ...

Embodiment 2

[0044] After the terraces were placed for several years, after operations such as fertilization and soil turning, the changes in parameters such as soil organic matter and pH value of the terraces are shown in Table 1;

[0045] Table 1 Total organic matter and water-soluble organic matter content of soil samples at different times after terrace reclamation

[0046]

[0047] Note: Soil sample 1-1 is the soil sample in October 2013 without fertilization and soil turning after terrace reclamation; soil sample 1-2 is the soil sample in October 2013 after fertilization and soil turning after terrace reclamation; soil Sample 2 is the soil sample in October 2014 after fertilization and soil turning after terrace reclamation; soil sample 3 is the soil sample in October 2015 after fertilization and soil turning after terrace reclamation; soil sample 4 is fertilization after terrace reclamation Soil samples were taken in October 2016 during operations such as digging and digging.

Embodiment 3

[0051] Before planting leguminous green manure crops, soak the seeds in 0.01-0.05% humic acid solution for 1 hour, then put them in a constant temperature box, keep a certain humidity, observe the germination rate of leguminous green manure crops, repeat three times for a certain concentration, and the seeds will germinate The rate is shown in Table 2;

[0052] Table 2 Germination rate of leguminous green manure crop seeds soaked in different concentrations of humic acid

[0053]

[0054] As can be seen from Table 2, when the humic acid solution concentration was 0.04%, it had the most obvious impact on the seed germination rate of legume green manure crops, and the germination rate reached 89%. After soaking like this, the germination rate of leguminous green manure crops was improved, and then Increase nitrogen fixation efficiency of legume green manure.
