Special matrix for blueberries and preparation method thereof

Abstract

The invention discloses a special matrix for blueberries. The special matrix is prepared from the following raw materials by weight: 20 to 30% of acidic peat soil, 42 to 50% of a biological organic material, 15 to 20% of NH4H2PO4, 5 to 10% of FeSO4, 5 to 10% of K2SO4 and 0.03 to 0.07% of trace elements. The invention also discloses a preparation method for the special matrix. The special matrix for blueberries prepared by using the method can adjust the surviving environment of blueberries, allows the blueberries to grow under proper growing conditions for a long time, promotes the growth of blueberries, enables blueberry branches to be stronger, substantially enhances the quality of blueberries and improves a fruit setting rate.

Description

technical field [0001] The invention relates to the technical field of fruit planting, in particular to a special substrate for blueberries and a preparation method thereof. Background technique [0002] Blueberry (Blueberry), scientific name Vaccinium Spp, belongs to Rhododendronaceae, Vaccinium genus, Vaccinium subgenus, wild berry species, perennial shrub, and the fruit is blue. Blueberry fruit is rich in anthocyanins, SOD, vitamins and rich mineral elements, which can activate the retina, strengthen eyesight and prevent visual fatigue. It is one of the five healthy fruits recommended by the World Food and Agriculture Organization. At present, the main cultivated varieties of blueberries are lowbush blueberry, half highbush blueberry, highbush blueberry and rabbit eye blueberry. The planting areas are mainly distributed in areas with a warm and cool climate and plenty of sunshine, such as North Korea, Japan, Europe, and North America. In my country, they are mainly distr...

AI Technical Summary

Problems solved by technology

The amount of nitrogen content in blueberry plants has a crucial impact on the yield and size of the fruit. Blueberries have a strong ability to absorb ammonium nitrogen in the soil. When nitrate nitrogen is applied, although the overall nitrogen level of the plant has increased, However, the fruit yield does not increase and the fruit becomes smaller, the maturity period is delayed, and the plant mortality increases

Excessive phosphorus fertilizers will not increase the yield, but will delay fruit ripening, inhibit the absorption of iron by blueberries, and cause iron deficiency symptoms

Appropriate amount of potassium fertilizer can increase the yield of blueberries, advance the ripening period, improve cold resistance and overall quality, but if excessive potassium fertilizer is applied, it will lead to a decrease in staleness, and in severe cases, it can cause symptoms of magnesium deficiency

In addition, blueberries are calcium-averse plants. When there is too much calcium, it will induce iron deficiency and chlorosis. Blueberries are also very sensitive to chlorine, which can easily cause excessive poisoning.
