Timely watering large cherries is highly dependent on water and is neither drought-resistant nor resistant. In order to ensure its normal growth, on the basis of timely pouring of flowers before flowering, after flowering, before harvesting, and before freezing, it is important to pour 10~15 days after flowering, this key water, watering amount is large, It is advisable to keep the water holding capacity in the soil field at 60%~70%.
Improve the microclimate of the orchard In order to avoid or reduce the damage caused by the high temperature weather before and after the cherry blossom period, the windbreak forest belt should be built when the site is built. Pay attention to the local weather forecast. Before and after the high temperature comes, take appropriate measures: support the shade net 30~50 cm above the crown before flowering, watering after flowering, and promote normal flowering fruit.
Before the flowering, the top dressing should be early, and the soil should be immediately released after thawing to promote the flowering and fruit setting of the year. About 1 month after harvesting is the flower bud differentiation period, and should be topdressed immediately, which can increase the flowering rate by 33.6%. At the same time, moderate amounts of trace elements such as calcium and boron are added.
The control tree has to go out of the strange circle of regulators alone. On the one hand, it is necessary to reduce the content of nitrogen in the soil, rational use of phosphorus, potassium fertilizer and medium and trace elements, and control from the source. On the other hand, immediately after the fruit is harvested, the stalks of the dense canopy are removed, and the Wangzhi, which has the value of use, is opened and opened, and the mites are gently cut to ease the growth and early flowering.
The decisive treatment of the spread of the virus tree virus tree is a major obstacle affecting the large cherry fruit. Once found, it must be dealt with in a timely manner. The whole plant should be removed, and the roots in the tree hole should be thoroughly cleaned; the branch of the local disease should be completely removed, and it cannot be changed, and it is impossible to collect pollination.
Reasonable match pollination Almost all the big cherries are self-sufficient. Many varieties have different incompatibility, and light blossoms do not result. Therefore, when cultivating large cherries, it is necessary to select more than two pollination varieties with similar flowering period, good gene, yield and quality, and the proportion should be about 30%.
The scientifically trimmed cherry has a soft xylem, a thick tube, and a stream of dead trees at the cut. Therefore, it is necessary to grasp the key period: the top of the bud is green and trimmed; the cultivating period is 10~15 days after the flowering and about 10 days after the harvesting. During these two periods of pruning, the wound is not easy to flow or less glue. The second is to pay attention to the method: according to the habit of the big cherry, it is necessary to use scissors and hands-on, mainly for summer shears, supplemented by winter shears. At the right time, pick up the heart, twist the branches, pull the branches, stabilize the tree, and grow flowers early.
