Introduction to three planting conditions and eight planting techniques of blueberry

Blueberries are so named because the skin of this fruit is blue. although blueberries are small, they are not as nutritious as other fruits. Eating blueberries regularly can not only fight aging, but also improve eyesight. The price of blueberries on the market is also more expensive, now popular blueberry picking gardens, you can pick blueberries themselves, growers are eager to try. Introduction of three planting conditions and eight planting techniques of blueberry.

I. planting conditions of blueberries

The main results are as follows: 1. The soil pH value of the garden site is 45.5, and the optimum soil pH value is 4.04.8. The content of soil organic matter is 8% to 12%, at least not less than 5%, the soil is loose, well ventilated, moist but without stagnant water. If the local rainfall is insufficient, an adequate source of water is needed. In order to solve the problem of stagnant water in summer, the strip platform field method can be used.

2. After selecting the garden plot, the green manure should be pressed and turned deeply one year before planting, and the suitable depth should be 20~25cm. If there are more weeds, you can spray herbicides one year in advance to kill weeds. The soil types that do not meet the requirements of blueberry should be improved before planting to facilitate the growth of blueberry.

3. The regulation of high soil pH value is an important factor limiting blueberry cultivation. Too high soil pH value often leads to iron deficiency and chlorosis, poor growth, low yield and even plant death. The effect of applying 130g sulfur powder can be maintained for more than 3 years, and other types of soil can refer to this amount.

2. Key points of blueberry planting techniques

1. Campus selection

The criteria for selecting soil types for cultivated blueberries are: slope no more than 10%; soil pH 4.0-5.5, preferably 4.3-4.8; soil organic matter content 8%-12%, at least 5%; loose, good drainage, moist but not stagnant water, if the local annual rainfall is low, there needs to be adequate water.

After the selection of the garden, apply peat soil 20 cubic meters per mu, mature cow dung 710 cubic meters, turn about 30 centimeters deep, then level the land, set up drainage ditches, remove stones, grass roots, hardwood blocks, etc.; after land preparation, carry on the platform field, the Mesa is 25 centimeters high and 1 meter wide, and plant a row in the middle of the table.

2. Soil improvement technology.

When the garden is selected, not all the soil can adapt to the growth of blueberry, and there are often some problems, such as too high pH value, too low pH value, sticky soil, insufficient content of organic matter and so on. Before planting, the soil structure, physical and chemical properties should be comprehensively evaluated, and the unsuitable soil conditions should be improved to facilitate the growth of blueberry.

The high pH value of soil is the main factor that limits the expansion of blueberry cultivation. Too high pH value will cause Fe deficiency, green loss, poor growth, low yield and even plant death of blueberries. When the soil pH is greater than 5.5, it is necessary to reduce the pH value: the most commonly used method is to apply sulfur powder to the soil, which should be combined with soil preparation one year before planting. The sulfur powder is uniformly removed into the ground according to the calculated dosage, turn deeply and mix well.

Note: sulfur powder should be applied throughout the garden, not only on the planting belt; soil covering sawdust, pine bark, application of acid fertilizer, and application of crude tannic acid can reduce soil pH value. The pH value of the soil should be tested once a year, and should be adjusted in time when it is higher than 5.5 or lower than 4.
