Introduction to planting conditions and techniques of cranberry

Cranberry is a kind of sweet and sour berry, which is one of the three traditional fruits in North America. It is commonly found in dried fruits in China, which is put in desserts and bread. Cranberries are deeply loved by consumers because of their high moisture, low calories, rich cellulose, minerals and so on. Let's take a look at the planting conditions and techniques of cranberries.

I. planting conditions of cranberries

Many varieties of cranberries are cold-resistant. Like humid and strongly acidic soil, cranberry is planted in wetlands to build a garden.

Cranberry orchards should have sufficient water sources to prevent frost, supplement excessive soil water evaporation and harvest cranberry fruits-the pH value of water harvesting irrigation water should be less than 6, and the best soil pH value is 4.0-5.5. Water sources include lakes, rivers, reservoirs, etc., and the reservoirs should store enough water to supply the growth of cranberries.

As cranberries are evergreen and semi-evergreen plants, cold resistance and frost damage should be considered when cultivating cranberries in cold areas of the north. Dry areas with less snow and strong wind in winter are not suitable for the development of cranberries; areas with frequent late frosts, such as valleys surrounded by mountains, are easy to suffer frost damage during flowering, which should also be avoided as far as possible.

2. Planting techniques of cranberries

1. Choose the right variety

It is necessary to choose a suitable variety to grow cranberries, and the main variety in North America is Stevens, which was cultivated in 1996. Stevens is a medium-ripe variety with large fruit, good coloring and good yield stability. Benlier is another widely cultivated variety with early maturity and larger fruit, but it is sensitive to cultivation and management measures. Several more varieties can be cultivated in one garden to reduce risk.

2. Soil conditions

Cranberries are not deeply rooted, so the surface of the soil should be covered with sand four or five centimeters deep. It has higher requirements for soil, peat soil is more suitable for its growth, in this soil, the survival probability can increase the fruiting period at the same time, and finally achieve the goal of increasing yield.

3. Planting

The common cultivation technique in North America is to cut off some of the rattan stems of cranberries when growing cranberries, sprinkle them in the sandy soil, then press them into the soil, and finally water and fertilize them, usually after a few weeks to grow new roots to become new plants. and the longer the better.

4. Pollination

Although cranberries are self-pollinated, the yield is very low and the fruit is very small, so many varieties are mixed, mixed pollination, and sometimes artificial pollination to ensure yield.

5. Harvest

There are two ways to harvest cranberries, which are divided into water harvest and dry harvest. The water needs a lot of water the night before the harvest, and then the next day the fruit is beaten down with a water wheel and then collected. Dry harvest does not need so much water, basically it can be said that the dry seed grows up, and it is good to pick the fruit after it is ripe.
