Tomato pods are tomatoes that have gaps between the flesh and the cavity. The appearance of empty holes will seriously affect the quality of tomatoes and reduce the value of their products. Therefore, vegetable growers should pay attention to reduce the production of tomatoes.
First, the cause of the empty fruit
1. For the seedlings that are easily detached from the flower buds, the development of the roots is generally poor, the number of roots is also small, and the assimilation is weak. Using growth hormone to promote fruit setting is easy to produce empty fruit.
2, the plant has a good flower buds, due to injury during transplantation, the formation of aging seedlings, root development after field planting in the field is not good, easy to cause leaf aging, weakened assimilation, can easily lead to empty fruit.
3. When the tomato leaf area is small, the first inflorescence is heavily fruited. The nutrient required for the fruit at the bottom of the plant is supplied by the whole plant, and there are fewer empty fruits, but less nutrients are obtained from the upper fruit and will form. Empty fruit.
4. In the same inflorescence, if the flowering time from the first flower to the sixth flower is not concentrated, it will cause competition for the assimilation of nutrients between the fruits, and the fruit of late flowering will form empty fruit.
Second, reduce the method of producing empty fruit
1. It is necessary to cultivate strong seedlings to increase the resistance of tomato seedlings. When planting, to reduce the damage to the root system, as far as possible with soil ball planting, to prevent the generation of aging seedlings.
2. According to different environmental conditions, a part of the fruit can be removed to increase the relative leaf area, so as to increase the assimilation of nutrients and prevent the emergence of empty fruit.
3, when the soil is rich in nitrogen, moisture, and high temperature at night, the flowering date is not easy. On the contrary, when the soil is slightly dry and the night temperature is low, flowering is more orderly. Pay attention to controlling the use of nitrogen fertilizer so that the flowering of the tomato is as consistent as possible. In addition, the high temperature during the night, especially after the application of nitrogen fertilizer and pouring water, most of the nutrients are distributed to the plants, but the fruit is allocated very little, in this case it is necessary to carry out the picking.
4. Reduce the number of growth regulators used and reduce the amount of growth regulators that enter the plant while ensuring a certain number of fruit sets. It is best not to use high-concentration growth regulators to treat immature flowers. This can reduce empty fruit. The production.
Chinese Cabbage is a biennial herb of Cruciferae and Brassica, with a height of up to 60 cm. The whole plant is hairless, most basal leaves are large, obovate oblong to wide obovate, the top is blunt, the edge is wrinkled, wavy, the petiole is white, flat, the flowers are bright yellow, the sepals are oblong or ovate lanceolate, upright, light green to yellow; Petals obovate, fruiting pedicels spreading or ascending, seeds globose, brown. It blooms in May and bears fruit in June.
Chinese cabbage was originally distributed in North China and widely cultivated all over China. Chinese cabbage is cold resistant and likes cold climate. It is not suitable to be planted on clay ground with poor drainage.
Chinese cabbage is rich in nutrition. Its leaves can be fried, raw, salted and pickled. The fallen leaves on the outer layer can also be used as feed, which has certain medicinal value.
Chinese cabbage is cold resistant and likes cold climate, so it is suitable to grow in cold season. If it is cultivated in high temperature season, it is prone to diseases and insect pests, or poor quality and low yield, so it is not suitable for cultivation in summer. It is very resistant to low temperature.
