Problems solved by technology

In most cases, the utilization rate of vinegar grains is only 20% as feed raw materials, biogas fermentation raw materials, edible fungus cultivation materials or plant soilless culture substrates, and 80% of vinegar grains rot cause environmental pollution around vinegar factories. During the stacking period, it not only occupies a large area of ​​land, emits a pungent smell, but also pollutes the soil and groundwater after being leached and infiltrated by rainwater.

Embodiment 1

[0021] Embodiment 1 A method of improving weakly alkaline tea garden with vinegar residue biogas slurry

[0022] In 2015, the method of the present invention was implemented in the tea garden of Xiazhang Town, Tai'an. The tea tree species planted in the tea garden for the experiment is the Jiukengqun species.

[0023] A blank control (without any treatment) and a prior art control (adding vinegar grains in a conventional manner) are set. Carry out the processing of the present invention, specifically as follows:

[0024] Mix vinegar grains obtained from Tai'an Shankou Food Brewing Factory with water at a volume ratio of 1:1, put them in a fermenter for fermentation for 2 months, and obtain vinegar grains biogas slurry with a pH value of 5.5-6.0.

[0025] First measure the pH value of the tea garden soil, which is 6.98, and determine the drip irrigation frequency as drip irrigation with vinegar residue biogas slurry once every two weeks, and each drip irrigation is 50L / mu; by...

Embodiment 2

[0028] Embodiment 2 A method of improving weak alkaline tea garden with vinegar residue biogas slurry

[0029] Implement the method of the present invention in the tea garden of Jinan Changqing District in 2015. The tea tree varieties planted in the tea gardens for the experiment are Huangshan Group species.

[0030] A blank control (without any treatment) and a prior art control (adding vinegar grains in a conventional manner) are set. Carry out the processing of the present invention, specifically as follows:

[0031] Refer to Example 1 for the preparation of the acetic residue biogas slurry used.

[0032] First measure the pH value of the tea garden soil, which is 7.3, and determine the drip irrigation frequency to be drip irrigation of vinegar residue biogas slurry once a week, and each drip irrigation is 50L / mu. When the test was started, the growth of the tea tree was not good. Buds, at the interval of drip irrigation with vinegar residue biogas slurry, add water to d...

Abstract

The invention discloses a method for amending an alkalescent tea garden by vinegar residue digested effluent. The method comprises the step: carrying out drip irrigation on tea garden soil according to certain frequency by using the vinegar residue digested effluent until the pH value of the tea garden soil is smaller than 6.5, wherein the frequency is arranged as follows: drip irrigation is carried out once biweekly when the pH value of the tea garden soil is not smaller than 6.5 and is not greater than 7; drip irrigation is carried out once weekly when the pH value of the tea garden soil is greater than 7 and is not higher than 7.5. The method for amending the alkalescent tea garden by the vinegar residue digested effluent further comprises the step of carrying out sprinkling irrigation on tea trees once every two days by using water-diluted vinegar residue digested effluent when the growth vigor of the tea trees is poor until the pH value of the tea garden soil is smaller than 6.5. According to the method, a drip irrigation mode is adopted and is combined with sprinkling irrigation if necessary, so that the aim of amending the tea garden is achieved while the utilization ratio of the vinegar residue digested effluent is increased; the flexibility is improved, so that the volume of the vinegar residue digested effluent applied is convenient to adjust according to the pH value of the tea garden soil; automation is achieved, the labor is saved, and the cost is reduced.

Description

technical field [0001] The invention belongs to the field of soil improvement, in particular to a method for improving weakly alkaline tea gardens with vinegar residue biogas slurry. Background technique [0002] The Jiangbei tea area is an area with poor tea growing conditions in my country. It is located in the north of the Yangtze River, south of the Huaihe River in the Qinling Mountains and parts of the east of the Yihe River in Shandong, including southern Gansu, southern Shaanxi, southern Henan, southeastern Shandong, northern Hubei, northern Anhui, and northern Jiangsu. The tea produced in this area has "high aroma" , strong taste, and resistance to brewing" are deeply loved by consumers; however, the terrain is complex and the precipitation is relatively low. Generally, the annual precipitation is below 1000 mm, and there are even fewer in some places. The tea gardens caused by farming and fertilization in this area Secondary salinization makes the soil pH of tea ga...
