Tomato seeds If produced cracked fruit, for the late food and harvest is very unfavorable, so we have to do a good job of processing, then in this case, how should we deal with it? Next, we might as well take a brief look.
Tomato seeds due to large changes in temperature and humidity and cracking, one is moderate insulation, according to crop needs and greenhouse conditions, at night can take a insulation blanket or add a layer of film, improve the temperature of the night greenhouse. At room temperature, keep the night temperature in the 13~15度, avoid the night temperature is too low, resulting in the temperature difference between day and night too large. Secondly, gradually ventilation, gradually increase the amount of ventilation, in order to avoid the temperature of more than 30 degrees when the wind, resulting in large changes in temperature and humidity.
Fruit cracking of tomato seeds caused by mutations in water and fertilizer conditions: In recent years, there are more rainy weather, and for a long time, watering has been continuous cloudy day, vegetable farmers have to delay watering, resulting in rapid changes in soil moisture. Fruit cracking. In this regard, we recommend the use of a small water pathway to replenish moisture, but it needs to be watered in the afternoon or the next day, with appropriate additional ventilation and ventilation time to reduce the humidity in the shed as soon as possible.
Attention should be paid to the concentration and timing of spraying disease prevention and treatment: In the recent rainy weather, some vegetable growers sprayed disease prevention, spraying concentration did not decrease, but increased, resulting in frequent drug damage, and easy to aggravate cracked fruit. It is recommended to avoid mixing with various pesticides during spraying and to choose sunny afternoons when spraying. It is wise to dry the liquid before sunset.
Replenish trace elements in time to avoid cracked fruit of tomato seeds due to lack of pigment. It is suggested that amino acids and seaweed foliar fertilizer should be sprayed to enhance the resistance of plants, reduce the harm of pesticides and reduce the possibility of fruit cracking.
