What to Do When Longan Doesn't Bear Fruit? Causes and Solutions
When growing longan, we find that many longan trees fail to bear fruit or bear very little. So why does this happen? When longan trees fail to bear fruit or bear little fruit, the loss to growers is enormous. When longan trees don't bear fruit, what should we do? And what issues should we pay attention to during cultivation? Let's read the content below for an explanation.
1. Why doesn't longan bear fruit?
Why doesn't longan bear fruit? There are many causes for this phenomenon, so we need to analyze it from different aspects. For example, differences in longan varieties: some varieties are not suitable for local cultivation, so they are very likely to fail to bear fruit. Next is inadequate management, such as failure to prune branches and leaves reasonably, failure to carry out scientific water and fertilizer management, and failure to properly handle intertillage, weeding, and earthing up. Another cause is failure to carry out pest and disease control, which leads to damage to the longan tree from pests and diseases, causing the longan tree to fail to bear fruit. Finally, climatic conditions also have a relatively large impact on longan trees, because China's climatic conditions vary considerably. In a given year, sudden climate change may cause temperature, rainfall, light, and other factors to fail to meet the growth needs of longan trees, resulting in failure to bear fruit.
2. Solutions
When longan trees fail to bear fruit, growers need to address this problem in order to reduce cultivation losses. Generally speaking, the first thing we need to do is understand the growth characteristics of the longan tree, and then choose the planting site according to its growth characteristics. Next is to select suitable varieties according to the local environment. Another point is not to apply excessive nitrogen fertilizer and to fertilize scientifically, using organic fertilizer, micro-fertilizer, and inorganic fertilizer scientifically according to the different growth stages of the longan tree. Manage field moisture reasonably, maintaining a certain level of humidity in the field, but without waterlogging.
3. Points to Note
When growing longan, there are also many things we need to pay attention to. First, we need to prune the longan tree to ensure ventilation and light penetration in the canopy, thinning out some of the dense branches, weak branches, non-fruiting branches, branches with few fruits, and water sprouts. Next is to increase the proportion of female flowers, so as to increase the fruiting amount of longan. Another point is to delay the flowering period and increase the pollination rate of female flowers, thereby improving the fruit-setting rate of longan. Then, during the full flowering period or fruit-setting period of longan, we should reasonably thin flowers and fruits to ensure the yield and quality of longan. Finally, carry out scientific control of longan tree pests and diseases, such as anthracnose, sooty mold, leaf roller moth, and stink bug.
When growing longan, many causes can lead to failure to bear fruit, but in fact the main cause is still a matter of cultivation techniques. If there are professional cultivation techniques and a rich understanding of longan cultivation, then these problems will be much fewer during the growing process.
