In the process of growing vegetables, watering and fertilizing are very common things, but it is such a simple thing, many people make mistakes every year, and often enter the misunderstanding of watering and fertilizing. Especially when planting fruits and vegetables such as beans, tomatoes, peppers, etc., if the watering and fertilization methods are not right, it is really difficult to make them grow well and bear much more. Although these vegetables need water and nutrients in the process of growth, they can not be watered and fertilized casually, and they must be reasonably watered and fertilized according to their respective water and fertilizer characteristics, so that they can grow well, the fruit can bear more, and the yield can be high.
Zhaoshui
Beans, tomatoes, peppers and other vegetables are most afraid of excessive watering that will cause excessive soil moisture, and once the soil is wet, it will cause rotten roots and dead trees. Especially from the seedling stage to the pre-flowering period, whether it is beans, tomatoes or peppers, the soil is slightly drier, which can not only control the growth of seedlings and growth, but also promote root development. If you water too much, the seedlings will grow vigorously, and the position of the fruit will move upward, and there will also be flower and fruit drops. In addition, it will also cause various diseases. For example, if the beans are watered too much, red root disease will appear, and tomatoes will be watered too much, which will lead to root soaking, etc.
Therefore, whether it is beans, tomatoes or peppers, watering must follow a principle, that is, do not dry and do not water, so how should we understand not drying and not watering? Simply put, there is no wet soil on the surface of the soil about 2 cm, and you can water at this time. Another way to judge is to pick up the soil layer, grab a handful of soil below 2 cm with your hand, and hold it hard, if the soil is clumped, you don't need to water, if the soil is not clumped by hand, it means that the soil is dry and can be watered.
In addition to deciding whether to water according to the dryness and wetness of the soil, different watering methods should be used according to different growing periods. Beans, tomatoes, and peppers should be slightly dry before flowering, and when they begin to bear fruit, they should increase the amount of watering appropriately to keep the soil moist. The so-called dry and wet soil refers to the fact that there is both dry soil and wet soil on the soil surface, which is dry and wet. Therefore, watering seems inconspicuous, and there is a lot of knowledge in it, which needs to be constantly explored and summarized according to different soil conditions.
fertilize
Many people have a misunderstanding about fertilizing melons, fruits and vegetables, most of them think that nitrogen fertilizer is used at the seedling stage, and potassium fertilizer is used after fruiting, which is a big misunderstanding. This problem has been said in the previous video, whether it is beans, tomatoes or peppers, including some other fruits, vegetables and root crops, nitrogen fertilizer must not be lacking in the fruit growth and expansion period, without nitrogen fertilizer, the fruit will never grow big, only nitrogen fertilizer can bear big fruit. But it doesn't work without potash. Therefore, nitrogen fertilizer is not only needed at the seedling stage, but also after fruiting.
Therefore, when topdressing beans, tomatoes and peppers, especially after fruiting, nitrogen fertilizer must not be missing, and nitrogen, phosphorus and potassium should be used together. If the nitrogen fertilizer is insufficient in the later stage, not only the fruit will not grow large, but the seedlings will also be prone to premature aging. Nitrogen fertilizer is called growth fertilizer, whether it is roots, stems and leaves, or fruits, the growth mainly depends on nitrogen fertilizer, and phosphate fertilizer and potassium fertilizer are to promote flowering, promote fruit coloring, promote fruit ripening, increase crop resistance to stress, disease, lodging and so on. Therefore, when topdressing melon and fruit crops, you must not use high potassium fertilizer alone, you must use nitrogen fertilizer, if you only apply potassium fertilizer without nitrogen fertilizer, the yield will never go up.
Through the above introduction, you should now know the importance of watering and fertilization, but whether it is watering or fertilizing, you need to adapt to local conditions and adapt to changes at any time according to different vegetables, different soils, and different growth.
