From March to April in spring, it is a good time for Rosaceae fruit trees such as peaches, pears, and cherries to bloom and bear fruit. If the orchard is not well managed during this period, the fruit trees will grow, as well as the fruit setting rate and fruit quality. And output have a great impact. Fertilize The flowering period will consume a lot of nutrients in the tree, which can be supplemented by applying fully decomposed organic fertilizers. The amount of fertilization should be adjusted according to the actual soil fertility, tree age, variety and yield, and water immediately after fertilization. Fertilization of soil during flowering period in spring is different from applying base fertilizer in autumn. Fertilization should not be too close to the trunk or too deep. Double cut The main purpose is to overcome the phenomenon of large and small yields and to adjust the load of fruit trees. The method is to cut off the weak branches, diseased dead branches, and over-dense branches, and try to keep the flowering branches; for those that are not confirmed to be flowering branches, they can be properly retracted and thinned out according to actual needs. Prevent pests and diseases During the period of bud expansion to leaf development, before and after flowering, the effect of spraying on pests and diseases is the best. In addition, you can also scrape off the rough bark, old peeled bark, and dead tissues in the spring. At the same time, remove the fallen leaves, fallen fruits, rigid fruits, diseased branches, dead branches, and orchard weeds in the garden, and concentrate composting. Thinning flowers and buds It is usually carried out at the initial stage of inflorescence separation to remove weak buds. If you don't have time to thin the buds, then you have to thin the flowers. When thinning flowers, you should keep side flowers, and omit late flowers and center flowers. Flowers in the first flowering stage are generally good flowers and should be kept all. One inflorescence should retain 3-5 side flowers. pollination If there are few or improperly planted pollinator trees in the orchard, artificial pollination can be used to increase the fruit setting rate. Commonly used artificial pollination methods include hanging pollinated varieties flower branch method, feather duster rolling pollination method, artificial point pollination method and spraying method. In addition to artificial pollination, areas and orchards where conditions permit can also be pollinated by bees during the flowering period, but pay attention to the effect of pollination. Pay attention to the application of boron fertilizer Boron fertilizer can promote the germination and elongation of pollen tubes, and promote the transportation of sugar in the tree. The use of boron fertilizer during flowering can increase the fruit setting rate. Antifreeze Rosaceae blooms mostly in the warm spring season, but at this time, if the spring is cold, the pistils will brown and shrink after the flowers are frozen, and they will not bloom and can not set fruit. Therefore, it is necessary to take precautions to prevent freezing damage. Disclaimer: Some articles on this website are transferred from the Internet.
