Vegetable control planting is also a big problem for vegetable farmers during planting. Especially for novices, what are the methods and techniques of vegetable control in the process of growing vegetables?
The first is the water control method. The water control method mentioned here is to control the amount of watering, create more adverse conditions for drought, and force the vegetable to grow from vegetative growth to reproductive growth. It can be judged by observing the growth of vegetables. If water passes through the leaves, the leaves of the vegetables will become green and thick, and the leaves at the growing point will no longer be yellow, indicating that the purpose of controlling water has been achieved; if the vegetables are wilting by controlling the water, it indicates that Excessive water.
Followed by the temperature control method, which is to create a low-temperature environment to achieve the purpose of controlling seedlings. The amount of air can be increased to increase the temperature difference between day and night. The temperature in the shed is maintained at about 25°C during the day and 13°C-15°C at night.
The last is the drug control method. The drug control method is mainly controlled by plant growth inhibitors. In general, the application of 750-fold booster and 1500-times dose of chlormethasine is more desirable.
