Vegetable farmers often say that tomatoes have hollow fruits, also called hollow fruits, which are mainly manifested by insufficient flesh, and the appearance of the fruit is ribbed, light in weight, and poor in quality. It is a kind of deformed fruit. The production of hollow fruit has a lot to do with weather and improper cultivation and management. The management measures are as follows: Strengthen temperature management From planting to the first inflorescence of tomato, it is necessary to manage the temperature well to ensure the normal differentiation of flower buds. It is recommended that vegetable farmers control the temperature at 23~28℃ during the day and 13~16℃ at night. Pay attention to root maintenance. Tomato root system is weak in winter. Try to water in the morning in winter, keep the ground temperature at about 15℃, and water with the minimum difference between water temperature and ground temperature, or store water in the reservoir in advance, and wait for the water temperature to rise. Water again when it reaches about 15 degrees Celsius. Combined with watering, apply functional fertilizers for root maintenance, such as chitin, alginic acid, microbial agents and so on. Root maintenance is a systematic "engineering" that needs to run through the entire tomato growing period. Reasonable supply of fertilizer and water After the tomato enters the flowering and fruit-setting period, the amount of nitrogen fertilizer should be appropriately controlled, the amount of potassium fertilizer should be increased, and the fertilizer should be used according to the growth of the plant. Pay attention to the alternate use of balanced fertilizer and high-potassium fertilizer. Don't be greedy for fruit retention. Pick out the fruits that have been sitting down but are underdeveloped in time to promote the rapid expansion of normal fruits. And pay attention to reasonable leaf picking, especially in the later stage, it is advisable to keep 1~2 pieces under the ear to avoid excessive leaf picking and aggravate the occurrence of hollow fruit.
