The latest course of planting techniques and methods of Big Cherry

Cherry, also known as bauhinia, warbler, cherry, etc., is the general name of some plum plants, including cherry subgenus, sour cherry subgenus, cinnamon cherry subgenus and so on. The fruit can be eaten as fruit, with bright color, crystal beauty, red as agate and yellow as fat. The fruit is rich in sugar, protein, vitamins, calcium, iron, phosphorus, potassium and other elements.

Planting conditions of cherry

Peaches like warm temperature and light, and adapt to the warm temperate East Asian monsoon continental semi-humid climate (moderate annual temperature, abundant rainfall, long frost-free period, early final frost period, annual average temperature of about 12 ℃, rainfall of more than 700 mm, frost-free period of about 250 days). Cherry is born on the sunny side of the hillside or on the edge of the gully, and is suitable for cultivation at an altitude of 300m to 600m and latitude 33 to 39 °north. Big cherry is suitable for cultivation in areas where the annual average temperature is above 10-13 ℃, the temperature does not change sharply in early spring, the summer is cool and dry, the rainfall is moderate and the light is sufficient.

1. Fear of drought

The root system of big cherry is very shallow, only distributed in the soil layer of 5-30 cm, the main root is underdeveloped, mainly from the lateral root to the oblique direction. Although the root system is shallow, the leaves are large, and they are constantly transpirating water. If the water is not replenished in time, the leaves will wither. Therefore, there is a saying that cherries do not leave water. When a cherry garden is built, it must be built in a place where there is water before the cherry orchard can be built.

2. Afraid of water

Cherry trees are afraid of stagnant water, and they will be destroyed if they soak for a day. It turns out that it is afraid of both drought and waterlogging. if the water content in the soil exceeds 25%, the root system of the cherry will suffocate, rotten roots, glue flow and other phenomena, and even lead to the death of the tree. From this point, we know that we can't choose waterlogged land to choose cherry orchards.

3. Big cherries are afraid of the wind, and we have to start from the characteristics of the root system. Big cherries have shallow roots, few main roots and many lateral roots, which can be broken in case of strong wind. That is to say, when building a garden, we have to analyze whether the wind is strong in this area and whether it will blow down the big cherry.

4. Afraid of sticking

The big cherry tree is also demanding on the land. It likes the granular loam, sandy loam, loam and light soil with deep soil layer, loose texture and high fertility, but does not like clayey soil, and the root system is underdeveloped in clayey soil.

5. Afraid of salt and alkali

Big cherry trees are sensitive to saline-alkali soil. If the salt content in the soil is more than 0.1%, big cherry trees are prone to yellow leaf disease, as well as boron deficiency, iron deficiency, calcium deficiency and other comprehensive deficiency. Using Dizibao trace element fertilizer will fundamentally solve this problem, filling a tree with 50 grams of Dizibao (30 jin of water). If there is a serious element deficiency, it is also necessary to spray 3-4 times of Dizubao solution.

In addition to the above points, big cherry also has certain requirements for climate. It is suitable for planting in areas where the annual average temperature is 7-14 degrees Celsius. The number of days in a year when the average daily temperature is higher than 10 degrees Celsius is between 150 and 200 days. The minimum temperature in winter can not be lower than minus 20 degrees Celsius.

Big cherry trees have high requirements for nutrients. When the content of organic matter in the soil reaches more than 12%, it will enter the fruiting period in three years, and the yield can reach more than 2000 kg (2 tons) per mu in four years. When the content of organic matter in the soil is less than 1%, the fruit is small, the taste is poor, and the yield is low.

Requirements for the establishment of cherry garden

Convenient transportation and water, climate and soil is the key, the back hillside is the safest, low temperature, late flowering, anti-freezing damage, full fruit.

After choosing a good garden site, it is only the first step to plant big cherries. Next, we should choose a good variety of big cherries. The principle is: good taste, good color, large size, high hardness, good storage and transportation price. This is the general requirement for big cherry varieties.

"Red Light", a big cherry variety bred by Dalian Institute of Agricultural Sciences in 1963, has become one of the fastest growing varieties in China because of its early maturity, large size, bright color and so on.

"Na Weng", also known as Huang Cherry, Huang Yang Cherry. It is an ancient variety of European origin. It was introduced into China by Incheon, South Korea around 1880, and is now the main variety in Yantai, Dalian and other places in China.

Pioneer was bred by Columbia, Canada. Zhengzhou Institute of Fruit trees, Chinese Academy of Agricultural Sciences, was introduced from the United States in 1983 and matured in mid-late June.

"Italian early Red": introduced by the Institute of Botany of the Chinese Academy of Sciences from Italy in 1989, the fruit is rich red, gorgeous, short stalk, single fruit weight is similar to red light, and it is also an early-maturing variety.
