Cherry tree planting: how to manage big cherry in autumn?

How to manage big cherry in autumn? Please introduce the management methods of big cherry trees in autumn. Autumn is the peak period of root growth of fruit trees, and it is also the key period for tree body to accumulate nutrients. The management of cherry trees in autumn can refer to the following methods. 1. Soil, fertilizer and water management of cherry orchards: 1. Soil improvement of cherry orchards: Cherry roots prefer sandy soil with good air permeability and high fertility. those who have not deeply turned over the soil during the construction of the mountain garden should be combined with autumn fertilization and increase the application of organic fertilizer to improve the soil. Sticky land needs to repair the drainage system and pay attention to drainage and waterlogging prevention. 2. increasing the application of base fertilizer to cherry trees: big cherry needs fertilizer early and concentrated in spring. In order to increase the nutrition of tree reserve, the application of base fertilizer in autumn is the key. The application time of base fertilizer should be carried out in the early and middle of September, and the amount of fertilizer should be determined according to the size of fruit trees. Fruit trees entering the fruiting stage are generally treated with 50 kg 100 kg organic fertilizer and mixed with 2 kg superphosphate, 0.5 kg 0.8 kg urea, 0.2 kg 0.3 kg borax and 0.2 kg 0.3 kg ferrous sulfate. The method of applying base fertilizer: the pit or ring ditch can be dug according to the projection of the tree body, the root system has been filled with the dense planting garden, and the strip ditch can be excavated along the outer edge of the crown projection, with a depth of about 30 cm. After the fertilizer is applied, it is watered to promote fertilizer with water. After the water is cut off and seeped, the pits and ditches are sealed with soil. Pay attention to avoid spreading fertilizer in the whole garden, causing the roots to float up. 3. Topdressing of cherry trees: foliar topdressing can prolong the functional period of leaves and make them produce more nutrients, which can be stored in fruit trees for root growth and sprouting and flowering next year. From mid-August to mid-September in autumn, it was sprayed every 10-20 days, for a total of 2-3 times. 0.5%-0.8% urea and 0.2%-0.4% potassium dihydrogen phosphate can be sprayed. Young trees with more prosperous production in autumn can be sprayed with 4% plant ash extract alone to promote branch maturity. Spraying must be carried out from 5pm to evening. Second, the shaping and pruning technique of cherry trees to remove big branches: in time to remove erect branches, over-dense branches and over-strong branches on the back in time in the middle and late August to improve the inner chamber light. The 1 ~ 2-year-old strong branches of the inner chamber can be cut moderately to promote the growth of branches, and the fruiting branches can be cultured. The outer branches of big purple and red lantern varieties left 1 or 2 branches to go outward, and the other outer branches should be thinned in the middle of September. Third, the improvement of cherry varieties due to the long childhood period of big cherries, after the beginning of fruit, it takes a long time to enter the period of high yield. If the varieties are not planted properly or mismatched, which will affect the efficiency of the orchard, it is necessary to improve the varieties. The grafting should be budding in August or branch grafting in spring of the following year. In August, when the second new shoot of the cherry tree stops growing and the third new shoot has not yet occurred, it is appropriate to use the method of wood bud grafting and improve it on the annual or biennial branches. The cherry varieties that can be regrafted are Red Lantern, Italian Zaohong, Ukraine No. 2, Dahong and so on.
