In recent years, family balcony farming is very popular, even in the cold winter, you can also grow vegetables on the balcony. Many people should find that the leafy vegetables in winter are still relatively expensive. If you grow your own, you can save a lot of money by taking it now. The winter terrace can also grow a wide variety of dishes, including small rapeseed, lettuce, cabbage, coriander and shallots, as well as some cold-tolerant root vegetables such as cherry radish and turnip. Balcony planting often encountered problems However, some people say that they grow vegetables on their balcony, they always have yellow leaves, and the leaves grow thin and small. So what is the reason? How to solve it? In fact, there is a difference between the cultivation of vegetables on the balcony and the cultivation of vegetables in the open field. It is still very difficult to make it grow as good as the open field. The experienced farmers introduced some small methods, that is, spraying potassium dihydrogen phosphate, so that the vegetables grow instantly and the green oil production is high. Why do families grow vegetables with yellow leaves? Whether it is planting flowers or growing vegetables, families are particularly prone to watering too much. Many people will be fresh after planting vegetables. In the morning, they will pour some water. When they get off work in the evening, they will have nothing to do with watering. The soil contains too much water. If the roots are not breathing well, it is very likely that they will root. In this case, the part of the plant on the ground is likely to grow bad. An obvious appearance is that the leaves are very yellow, thin and long. In this case, controlling watering is the most effective method. One principle is to “see dry and wetâ€. If there are potted vegetables, the growth environment is relatively small, which is not conducive to root growth. Therefore, we can supplement the roots with phosphorus and potassium fertilizers, which can promote hair roots, roots grow faster, roots grow better, and yellow leaves are naturally less. Usage of potted vegetable potassium dihydrogen phosphate Potassium dihydrogen phosphate is a quick-acting phosphorus-potassium compound fertilizer, which can delay the senescence of leaves and roots. For potted leafy vegetables, this leaf fertilizer can be sprayed when it grows to three or four leaves after sowing, but if the growth cycle of the leafy vegetables you grow is relatively short, only about one month, then spray two Three times is enough. The concentration of 0.3-0.5% potassium dihydrogen phosphate can be sprayed evenly on the foliar surface, and the front and back sides of the leaves are uniformly sprayed, so that the absorption is better. In the process of growing vegetables, if vegetables are vegetables If you are not good, then it is recommended to spray this medicine to try. Another good use of potassium dihydrogen phosphate is soaking seeds, soaking seeds and then sowing. The seeds grow into strong seedlings, so that the vegetables grow well and the yield is also increased. The specific method is to prepare potassium dihydrogen phosphate to a concentration of 0.2%. The solution is soaked for 10-12 hours. After the fish is removed, it can be dried and soaked. Potassium dihydrogen phosphate is also used in the cultivation of greenhouse vegetables. Many old farmers see that tomatoes grow old and not too strong, and they are yellow and weak. They will spray some potassium dihydrogen phosphate. As soon as the spray is finished, the effect is Very obvious, after a few days, it will grow green and the roots are old and thick.
