Soil conditioner for blueberry cultivation

Abstract

The invention discloses a soil conditioner for blueberry cultivation. The soil conditioner comprises the following components in parts by weight: 100-120 parts of a bioorganic fertilizer, 80-90 parts of fermented bean residue, 20-30 parts of furfural residue, 40-45 parts of turf, 8-13 parts of humic acid, 10-15 parts of moss, 3-5 parts of functional polypeptide, 15-18 parts of a water-retaining agent, 150-180 parts of an auxiliary agent and 10-30 parts of a conditioning agent. The soil conditioner has the beneficial effects as follows: the furfural residue is used for substituting sulfur, so that the cost is reduced, the environment is improved and the pH value of soil is significantly reduced; a functional polypeptide calcium complex can inhibit calcium absorption of a blueberry root system and prevent iron-deficiency chlorosis or death of blueberry; the soil conditioner has the effects of fixing carbon, retaining water, reducing the soil bulk density, increasing the porosity and the like, is high in organic matter content, helps to increase the seed germination rate, promote the root system growth and delay root system aging in the later stage, and is a high-efficiency and environment-friendly soil conditioner for the blueberry cultivation.

Description

technical field [0001] The invention relates to the field of soil improvers, in particular to a soil improver for blueberry planting. technical background [0002] Blueberry is a kind of blue berry, belongs to Rhododendronaceae, Vaccinium plant, originates in North America, perennial shrub small berry fruit tree, because the fruit is blue, so it is called blueberry. Blueberry fruit is rich in nutrients such as protein and vitamins, and the content of minerals and trace elements is also considerable. Blueberries are rich in anthocyanins, which can activate the retina, strengthen eyesight, and prevent eye fatigue. One of the five healthy fruits recommended by the organization. According to research by scientists from the United States, Japan, and Europe, blueberry products have the functions of preventing brain nerve aging, protecting eyesight, strengthening the heart, anti-cancer, softening blood vessels, and enhancing human body immunity. The original population of blueber...

Problems solved by technology

[0004] At present, there are many methods about the improvement agent technology of blueberry planting soil. The prior art such as the authorized public number is a Chinese invention patent of CN103396262 B, which discloses a special soil improvement agent for blueberry planting. The method uses vinegar grains, wood powder, sulfur powder, Potassium sulfate compound fertilizer is combined with Bacillus, which has the advantages of environmental protection, energy saving and recycling. However, it uses sulfur powder to reduce the pH value of the soil. Studies have shown that the use of sulfur can change the biological structure of the soil and increase the salt content of the soil. Blueberries need soil with strong air permeability and strong water holding capacity, and the growth of blueberries requires nitrogen fertilizers instead of potassium fertilizers. Therefore, the soil improved by this soil improver cannot fully meet the conditions required for blueberry growth, so it has no promotion value
