Soil acid adjustment method used for blueberry plantation

Abstract

The invention discloses a soil acid adjustment method used for blueberry plantation. According to the soil acid adjustment method, dilute sulphuric acid is packaged with composite material coated fiber membrane bags (sustained-release membrane bags), and is placed close to the root of saplings, so that molecules are released and conducted into soil gradually via coating fiber, and requirements of blueberry on pH value of cultivating soil are satisfied, wherein the composite material coated fiber membrane bags are penetrated by the coating fiber. Sustained release effect of the coated fiber membrane enables that pH value of blueberry root local environment can be adjusted in time, durability can be achieved via supplement of the packaged liquid, and the soil acid adjustment method is convenient, economical, and long-acting. The soil acid adjustment method is capable of adjusting soil pH value to a reasonable range required by blueberry rapidly and conveniently; local soil acid adjustment improvement benefits are achieved as far as possible, so that waste is reduced; utilization effect is long lasting and excellent; and when the packaged liquid becomes insufficient, supplement can be realized via bottle openings.

Description

technical field [0001] The invention belongs to the technical field of fruit tree cultivation, and in particular relates to a method for adjusting soil acidity for planting blueberries. Background technique [0002] Blueberry, also known as "bilberry" or "bilberry", is an important economic plant of the Rhododendronaceae Vaccinium genus. Because of the antioxidant active substances such as anthocyanins in its fruit, it has the functions of improving eyesight, anti-aging, anti-tumor, It is known as "21st Century Functional Health Berry" and "Queen of Fruits" for its efficacy in treating cardiovascular and urinary system diseases, and is listed as one of the five health foods for human beings by the International Food and Agriculture Organization. [0003] The cultivation of blueberries has a history of less than 100 years. The domestication of wild blueberries began at the beginning of the last century. American Coville first selected and bred some excellent wild blueberry va...

Problems solved by technology

Dilute sulfuric acid is packaged with a composite coating fiber membrane (slow-release membrane) and placed at the root of the saplings. The coated fiber that runs through the inside and outside of the membrane gradually releases conductive molecules into the soil to solve the problem of blueberry's demand for the pH value of the cultivation soil.
