How to scientifically apply liquid fertilizer during bell pepper cultivation
Compared with some common vegetable crops, bell peppers do not have a very well-developed root system. Moreover, if the roots are damaged, their ability to regenerate is very weak. Therefore, applying liquid fertilizer to bell peppers is crucial; applying liquid fertilizer to bell peppers is not only to supplement the plant with sufficient nutrients, but also to promote root growth. So how should you apply liquid fertilizer when growing bell peppers? Today, the editor will give you a brief introduction. Let's take a look below!
1. Liquid fertilizer application before fruiting
When growing bell peppers, under normal circumstances, do not apply liquid fertilizer before the bell peppers set fruit. Because if there is too much fertilizer, it can easily lead to excessive nutrients, causing the plants to grow excessively. However, we still need to decide based on the actual situation. For example, in the early stage after bell peppers are transplanted, if the seedlings root slowly and recover slowly from transplanting, then we should apply an appropriate amount of liquid fertilizer to promote rooting, enhance the growth ability of the seedlings, and achieve the effect of promoting seedling growth. The fertilizer used for liquid application can generally be biological bacterial fertilizer to promote rooting.
2. Liquid fertilizer application in the early fruiting stage
In the early fruiting stage of bell peppers, you should begin to pay attention to liquid fertilizer application. We should pay attention to applying an appropriate amount of fertilizer, with the main focus on promoting plant growth and fruit development. When the bell pepper fruits grow to about the size of an egg, begin applying liquid fertilizer to the plants. Pay attention to the timing of liquid fertilizer application during this period; it should not be too early or too late. If it is too early, then excessive nutrients and water will cause the plants to grow too vigorously, leading to phenomena such as fruit scorching and reducing the speed of fruit development. If it is too late, then it will affect the development of the upper part of the plant and the flower buds, reducing yield.
3. Liquid fertilizer application during the fruiting stage
After bell peppers formally enter the fruiting stage, their demand for potassium will become greater and greater. Therefore, when applying liquid fertilizer during the fruiting stage, the fertilizer should mainly be high-potassium fertilizer to meet the potassium demand of bell peppers during the fruiting stage, enhance the disease resistance and growth ability of the plants, and increase yield. Moreover, at this time, bell pepper plants will carry out both vegetative growth and reproductive growth, so a large amount of nitrogen fertilizer is also needed as a guarantee. Therefore, the liquid fertilizer should mainly be high-nitrogen and high-potassium, and at the same time, in order to prevent premature aging of the plants in the later stage, an appropriate amount of root-promoting liquid can be applied.
4. Liquid fertilizer application during the full fruiting stage
Finally, we also need to pay special attention to liquid fertilizer application during the full fruiting stage. During this period, a large amount of liquid fertilizer should be applied, mainly to preserve flowers and promote fruit development. As bell peppers gradually enter the full fruiting stage, their growth direction is mainly reproductive growth. This is also to ensure that the bell pepper fruits can expand normally, and to promote flower bud differentiation. Then, as the number of fruits on the plants continues to increase, the amount of fertilizer applied should also be slowly increased, but each time liquid fertilizer is applied, be careful not to apply it too heavily, to avoid fertilizer damage.
The above is a brief introduction to how to apply liquid fertilizer when growing bell peppers. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
