Causes of unsuccessful reasons: 1, it may be climate is not suitable. 2. Inappropriate cultivation and management result in over-growth of tree vigor. Flower buds are not formed and will not result.
The prevention and control measures are as follows: 1. It depends on whether the local area is suitable for planting cherries. Cherry is divided into Chinese cherries and European sweet cherries. Chinese cherries have a wide adaptability, and European sweet cherries have relatively narrow adaptability. They have strict requirements for climatic conditions. They require adequate illumination, less precipitation, large temperature difference between day and night, and sufficient low temperature in winter. , otherwise flowering is difficult, or flower bud differentiation and development is poor. 2, reasonable summer trim. Young cherry trees are often not easy to flower and must be cultivated with reasonable summer trimming. For example, in the late May to early June, the tips of the branches on the back or the tips of the 30 cm can be trimmed. During the period from July to August, the branches and branches are pulled. Pulled to about 80 degrees, auxiliary support branches, the results of the branches pulled to 90 degrees or more, control of vegetative growth, promote flower bud differentiation and flower cluster short fruit branch formation, with earlier results. 3, take measures to promote flowers. The fruitless cherry trees can be repeatedly tossed, and the spraying of plant growth inhibitors such as paclobutrazol for foliar spray from June to August can effectively control the growth potential and promote the transfer of plants from vegetative to reproductive growth, thereby promoting flower bud differentiation and achieving results. purpose. 4, flowering and fruit preservation. Full flowering spray 0.3% ~ 0.5% borax solution, or 0.3% urea + 0.3% borax + 0.3% potassium dihydrogen phosphate 1 ~ 2 times. 5. Strengthen pest control and fertilizer and water management.
