First, keep ground temperature constant Proper ground temperature is the key to ensure the normal growth of vegetable roots. The optimum temperature for root growth of vegetables such as cucumber, eggplant, tomato and pepper is 20°C-22°C. Temperature at 12 °C, vegetable root physiological activity was blocked; at 8 °C, vegetable roots basically stopped growing; vegetables below 5 °C were frozen and died. Therefore, in the management of winter vegetables in the protection must be based on the type of vegetables to adjust the ground temperature, such as the ground temperature is too low we must increase the temperature within the shed, or take the whole film to cover. Second, to be reasonable watering and fertilizing Watering is unreasonable, the soil is too dry or too wet, and it has a great influence on the root system of vegetables. In particular, watering suddenly when the temperature is high at midday is the most likely to cause damage to the hairy roots of vegetables. Therefore, it is best to water before 10:00 in the morning, the amount of water should not be too large, avoid flooding irrigation, pay special attention in the winter. When the soil is dry and wet, it should be timely scratched to increase the permeability of the soil and promote the growth of the root system. Fertilizer must be careful not to overdo it once, so as not to enlarge the roots. In winter, care must be taken not to flush the fertilizer with high nitrogen content to prevent evaporation of ammonia from the vegetables. Third, we must pay attention to the application of biological fertilizer Biological bacterial fertilizer has the effects of improving soil structure, enhancing soil fertility, inhibiting soil-borne diseases, and protecting root systems. Therefore, vegetable growers must pay attention to the application of biological bacterial fertilizer when topdressing. In addition, we must also guard against soil-borne diseases and the hazards of underground pests. All kinds of pests and diseases should be prevented and prevented in time.
