The water content of tomato fruit varies with the variety. The same variety has different performance in the cultivation process due to different management levels and different environmental conditions. The fruit and tomatoes sold on the market in early spring this year appear to have There are many corners and many empty fruits. The reason is that the fruit lacks sufficient moisture during the expansion period, which affects the normal growth of the fruit and leads to hollows in the fruit cavity. This not only affects the commodity, but also reduces the yield by 8% to 10%.
To control or reduce the empty fruit of the tomato, we must first select the appropriate variety. When we are going through the wintering cultivation, we must choose the varieties that are resistant to low temperature and low light; secondly, we should according to the physiological characteristics of tomato, carry out the temperature and moisture in the cultivation and management. The management, especially the fruit from the beginning of the expansion to the fruit ripening period, to keep the soil moisture above 60%, keep the soil moist, watering according to the soil moisture content. If you encounter a long period of cloudy days, or low-temperature weather, you must take a small amount of water, and pour it in the depth of 15 to 20 days during the deep winter (choose sunny morning), and pour it once every 7 to 10 days in the early spring, if it reaches 3, In April 4~5 days, it is poured once, but it is necessary to adopt small water inter-irrigation, which meets the needs of tomato growth, and it is not easy for water to be too much, and at the same time reduce tomato cracking. The adaptability of tomato to temperature is relatively strong, but the requirement for the temperature in the range of 15 °C ~ 26 °C in order to normal growth and absorption of soil moisture and nutrients, if the ground temperature is too low will directly affect the absorption of water, the same will appear empty Fruit or malformed fruit; third, timely top-dressing, combined with top-dressing at the time of watering, in the deep winter low temperature period can be followed by 15 to 20 kg/667? of rotten bean paste, combined with biological fertilizer with water, or Foliar sprayed with fertilizer (main components: Mn + Zn + B ≥ 20g/L; amino acids ≥ 100g/L) diluted 500 times (Luhong Agricultural Sciences), dedicated to Jinkela vegetable (main components: N + K2O ≥ 20%; humic acid ≥ 4%) diluted 150 times (Lu Hong Agricultural Branch), alternating application, interval 10 to 15 days, can effectively prevent or reduce the tomato empty fruit.
