Four points for attention in planting big cherry

After trial planting, big cherries like to be warm, not cold-tolerant, not tolerant to drought, not tolerant to waterlogging and afraid of strong wind, so they are suitable for cultivation in areas with an annual average temperature of 10 ℃ ~ 15 ℃. Practice has proved that when the annual average temperature is higher than 15 ℃, big cherries tend to blossom more and set less fruit. The introduction and development of big cherries should not only depend on the local annual average temperature, precipitation, sunshine, frost-free period and other factors, but also carefully analyze the local microclimate characteristics, first trial planting, and then development. At present, there are only more than a dozen excellent cherry varieties that have been proved by cultivation, and each variety has some shortcomings. Such as the red light cultivated by our country, it has large fruit, bright color, juicy sweet taste, high and stable yield, but it enters the full fruit period late, the fruit skin is thin, the meat is soft, so it is not suitable for processing, storage and transportation, and is only suitable for small area planting. In the future, cherry varieties with beautiful appearance, hard pulp, good quality, light crack, resistance to storage and transportation, fresh food and processing should be selected. The selection of good rootstocks suitable for local cultivation is the key to the successful cultivation of cherry. The most important thing is to see whether the rootstock is resistant to root cancer and virus disease. In the old cherry producing areas, the development of big cherries must not use continuous cropping land, let alone use continuous cropping land to raise big cherry seedlings; in the newly developed cherry producing areas, under the premise of identifying improved varieties and rootstocks, we should strictly control root cancer and virus diseases. Pollination and fruit thinning are required. Most large cherry varieties do not bear fruit or have very low seed setting rate, so cross-pollination is needed. Some big cherry orchards with no high yield and suitable age for years and little fruit are not affected by freezing injury, but mainly due to unreasonable configuration of pollination trees, rare florescence and poor pollination. Pioneer and Rabins are all ideal pollination varieties. It is also necessary to timely remove the weaker fruit branches, remove the smaller flowers, and remove the small fruits and malformed fruits that are not in the right shape and position. It is appropriate to leave 2 or 3 fruits on each strong fruit branch.
