What is the result of Russia on the 8th?

Russia's 8th, also known as Hanxiang, is a new big cherry seedling introduced from Russia by Zhang Diangao, former director of the Fruit Tree Bureau of Wafangdian City in Dalian, Liaoning Province, and its fruit is earlier than that of ordinary cherry trees. So, what is the result of Russia on the 8th?

1. What is the result of Russia on the 8th?

Russian cherry No. 8 generally can hang fruit in the second year after planting, and began to show a high yield trend in the fourth year, and the yield increased significantly year by year.

II. Matters needing attention in planting Russian No. 8

1. Afraid 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 stickiness: the big cherry tree also has strict requirements on the land. It likes the granular loam with deep soil layer, loose texture and high fertility, sandy loam, loam and light soil, but does not like clayey soil, and the root system is poorly developed in clayey soil.

5. Fear 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, 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.

The fruit of Russian No. 8 cherry is broadly heart-shaped, with protruding shoulders, broad shoulders and convex chest. When ripe, the fruit color gradually changes from bright red to black and purple, oily black and bright, sweet pulp, slender stalk, large fruit, average single fruit weight 12.9 grams, thick and tough pericarp, strong elasticity and strong sweet flavor.
