How many years does it take for Russian No. 8 large cherry to bear fruit?
Russian No. 8, also known as Hanxiang, is a new large cherry sapling introduced from Russia by Zhang Diangao, former director of the Fruit Tree Bureau of Wafangdian City, Dalian, Liaoning Province, and it bears fruit earlier than ordinary cherry trees. So, how many years does Russian No. 8 take to bear fruit?
1. How many years does Russian No. 8 take to bear fruit?
Russian No. 8 cherry generally begins to set fruit in the 2nd year after planting, shows a trend toward high yield starting in the 4th year, and its yield rises noticeably year by year.
2. Points to note when planting Russian No. 8
1. Sensitive to drought: the root system of large cherry is very shallow, distributed only in the 5-30 cm soil layer; the main root is not well developed, and it mainly develops from lateral roots growing diagonally outward. Although the root system is shallow, the leaves are relatively large and continuously transpire water; if water is not replenished in time, the leaves will wilt, hence the saying that cherries never leave water. When establishing an orchard, it must be built in a place with irrigation water before a cherry orchard can be established.
2. Sensitive to water: cherry trees are afraid of waterlogging; soaking for one day can ruin the tree. It turns out they are afraid of both drought and waterlogging. If the water content in the soil exceeds 25%, the root system of large cherry will suffocate, and root rot, gummosis and other phenomena will occur, and it may even cause the tree to die. From this we know that when choosing a cherry orchard site, we must not choose low-lying waterlogged land.
3. Large cherry is afraid of wind, which again comes back to the characteristics of the root system. Large cherry has shallow roots, few main roots and many lateral roots, and strong winds can break them, which means that when establishing an orchard, one must also analyze whether the wind in the area is strong and whether it will blow the large cherry trees down.
4. Sensitive to clay: large cherry trees are also quite demanding about soil. They like granular loam, sandy loam, loam and light soil with deep soil layers, loose texture and relatively high fertility, and do not like clayey soil; in clayey soil the root system develops poorly.
5. Sensitive to salt and alkali: large cherry trees are relatively sensitive to saline-alkali land. For example, if the salt content in the soil exceeds 0.1%, large cherry trees are prone to yellow-leaf disease, and also to comprehensive nutrient deficiency symptoms such as boron deficiency, iron deficiency and calcium deficiency. Using Dizhongbao trace element fertilizer will fundamentally solve this problem; irrigate 50 grams of Dizhongbao per tree (mixed with 30 jin of water). If the deficiency is severe, spray 3-4 rounds of 300-fold Dizhongbao solution. In addition, large cherry trees have very high nutrient requirements. When the organic matter content in the soil reaches more than 12%, they enter the fruiting stage in three years and reach the high-yield stage in four years, with a yield per mu of more than 2000 kg (2 tons); when the organic matter content in the land is less than 1%, the fruit is small, the taste is poor and the yield is low.
The fruit of Russian No. 8 large cherry is broad heart-shaped, with protruding, broad shoulders and a chest protrusion. When ripe, the fruit color gradually changes from bright red to black-purple, glossy black, the flesh is sweet, the stalk is slender, and the fruit is relatively large, with an average single fruit weight of 12.9 grams; the skin is thick and tough, highly elastic, and the sweet aroma is strong.
