Pollution-free blueberry soil pH regulating solution and use method thereof

Abstract

The invention provides a blueberry soil pH regulating solution which is turbid liquid obtained after tomatoes which are not completely ripe are mashed and then naturally fermented.The regulating solution is applied to soil before blueberry planting and soil with the pH value higher than 5.0 after blueberry planting, the regulating solution is used for irrigating blueberry planting pits, and blueberry planting is conducted till the pH value of soil is 4.5-5.0; after blueberry planting, the regulating solution is specifically applied to a blueberry garden with the pH value of soil higher than 5.0, the roots of planted plants are regularly irrigated every 4-7 days by means of the regulating solution till the pH value of soil is 4.5-5.0, and irrigation ends.The blueberry soil pH regulating solution has the advantages that the pH regulating solution is safe, free of pollution, convenient to apply and high in organic matter content, and soil hardening is not caused.

Description

Technical field [0001] The invention relates to the technical field of blueberry soil adjustment, in particular to a blueberry soil pH value adjustment liquid and its application. Background technique [0002] Blueberry (blueberry) is a plant of the genus Vaccinium L. belonging to the genus Ericaceae (Ericaceae). It is a perennial deciduous or evergreen shrub. Its fruit is a blue berry, with delicate flesh and moderate sweetness and sourness. Blueberry is rich in nutrition, is a health fruit with high amino acids and many trace elements. It has good nutrition and health care, anti-oxidation, anti-cancer, and strengthen human body immunity. The anthocyanins contained in it can improve vision and protect eyes. [0003] With the improvement of people's living standards, the demand for blueberries is also increasing, and blueberry cultivation or cultivation has also attracted attention. Blueberries have extremely strict requirements on the soil conditions of the planting land, especia...

Problems solved by technology

Although sulfur can lower the soil pH and play a role in killing insects and bacteria at the same time, it takes a certain period of time to play its role after application, so it needs to be applied in advance half a year to one year before blueberry planting, and long-term or excessive application will make the Soil compaction affects other biological conditions, and it is inconvenient to apply blueberries after planting; although iron sulfate, aluminum sulfate and potassium sulfate can also reduce soil pH to a certain extent, the cost is high, and they can only be properly applied during fertilizer and water management. Apply, and the amount of application should not be too large, it is difficult to achieve the ideal soil pH

[0005] In recent years, although some researchers have used furfural slag instead of sulfur to adjust soil pH and achieved good results, but its source is limited to furfural production and chemical enterprises, it is not easy to obtain, and it is difficult to meet the needs of blueberry production areas across the country
