Spring is the peak season of greenhouse vegetable growth,  is the key period to obtain high yield. Agricultural experts analysis, although now has entered the spring,  but warm and cold air activities frequently, the temperature change range is large,  vegetables want to obtain high yield, management should pay attention to the following points.

Spring temperature is gradually rising, greenhouse vegetables have gradually entered the rapid growth period, soil moisture is required to meet the needs of vegetable growth. Greenhouse air humidity should not be too high, otherwise easy to breed disease. To strengthen ventilation, reduce humidity, as much ventilation as possible under the condition of temperature. Vent in the shelter, otherwise easy to flash seedling. When irrigation is short of water in the field, flood irrigation should be avoided

Change the way you water. After the weather gets warm, vegetable water demand increases, pay attention to watering flushing fertilizer interval is shorter than low temperature season, generally every 10 days or so pouring water, it is best to use a combination of water and small water watering. Timely rectification and branching, adjust the shape of the plant

Two, the temperature is unstable

Defensive remedies need to be strengthened

Therefore, vegetable farmers should act actively and take effective defensive measures in technology to cope with the impact of low temperature weather on vegetables.

Three, it is windy and rainy

Strengthen the shed to guard against sand
