The causes and control methods of the latest anti-wind bolting
Fangfeng is a traditional Chinese medicine, which is mainly used to treat cold and skin diseases. with the expansion of its market demand, a large number of wild resources are picked, resulting in the gradual scarcity of wild resources and the rise of artificial planting. But the phenomenon of bolting will occur when planting, which affects the yield and quality of Fangfeng. Let's take a look at the causes and prevention methods of Fangfeng bolting together with the editor.
First, the cause of bolting
There are two main reasons for Fangfeng bolting, one is caused by nutrition, Fangfeng flower bud differentiation is sufficient fertilizer and water, loose soil, plant growth will be accelerated, flower bud differentiation will be in advance, there will be the phenomenon of immature bolting. The second is caused by photosensitin, which controls the flowering of plants. In artificial planting, because there is no shade of weeds, Fangfeng is more active than wild resources, so it is more active. It will cause Fangfeng to bolt and blossom.
II. Prevention and control methods
The main results are as follows: 1. In the seedling stage, base fertilizer should be applied properly, and chemical fertilizer should be applied little or no during the growth process, so as to avoid early flower bud differentiation and early bolting caused by plant overnutrition.
2. When planting, it is necessary to keep reasonable close planting and pay attention to the planting density. In general, it is possible to keep 300000 seedlings per mu, while planting in the field only needs to keep 30, 000 seedlings. Make the plants shade each other and reduce the light intensity, which can prevent the rapid growth of Fangfeng and inhibit the flower bud differentiation of Fangfeng.
3. Control watering to force the root system of Fangfeng to grow downward and increase the length of the root system, so as to avoid bolting caused by abundant water. Generally, when planting, you only need to water the slow seedlings 1-2 times, and try to water little or no water after survival, so as not to cause bolting.
4. Once it is found that there is a bolting Fangfeng, the Reed head should be cut off in time, so that the plant will remove the hormone of flower bud differentiation, so that it can sprout adventitious buds again, which is very effective in preventing and controlling wind bolting.
The above is the introduction of the causes and prevention methods of Fangfeng bolting. I hope it can help you. If you want to know more about it, please follow us.
