What should I do if the tomatoes in the greenhouse "rise"?

Recently, vegetable farmers have often heard the problem of tomato ridges. In fact, vegetable ridges are actually hollow fruits, also called hollow fruits. The main manifestation is that the flesh is not full, the fruits on the surface are ridged, light in weight, and of poor quality. It is a kind of deformed fruit. The production of hollow fruits is closely related to the weather and improper cultivation management. The management measures are as follows:

Strengthen the temperature management. From the planting of the tomato to the first inflorescence, it is necessary to manage the temperature to ensure the normal flower bud differentiation. It is recommended that vegetable farmers control the temperature at 23-28 ° C during the day and the temperature at 13-16 ° C at night.

Pay attention to root system maintenance. Tomato root system is weak in winter. Watering should be selected in the morning as much as possible in the winter. The ground temperature should be maintained at about 15 ℃ and the temperature difference between the water temperature and the ground temperature should be as small as possible. Water to about 15 degrees Celsius. Combined with watering, functional fertilizers such as chitin, alginic acid, and microbial inoculants should be applied. Root maintenance is a systematic "engineering" and needs to run through the tomato growing season.

After a reasonable supply of fertilizer and tomato enters the flowering and fruiting stage, the amount of nitrogen fertilizer should be appropriately controlled and the amount of potassium fertilizer should be increased. At the same time, the fertilizer should be used according to the growth of the plant, and the balanced fertilizer and high potassium fertilizer should be used alternately.

Don't be greedy for the retained fruit. Remove the stagnant but stunted fruit in time to promote normal fruit expansion. And pay attention to reasonable leaf picking, especially in the later stage, it is advisable to keep 1 or 2 under the ears to avoid excessive leaf picking and exacerbate the occurrence of hollow fruits.
