Selecting high-quality varieties is the foundation. Many people say that tomatoes are not delicious, mainly because most tomato varieties tend to yield, and they are very conducive to transportation and storage, and the taste of tomatoes is slightly reduced. Therefore, tomatoes planted in small vegetable gardens or balconies should choose old varieties with high taste and can be eaten as fruits.

Second, tomato pollination.

When many farmers grow tomatoes, they will encounter the situation that they will not bear fruit. Tomato can't bear fruit without successful pollination, so pollination is a very important problem. Tomatoes are self-pollinated. Tomatoes planted in the open air generally do not need pollination, but can be pollinated by insects. However, if it is planted on the balcony, it needs pollination.

There are many ways to pollinate tomatoes. The first method is to use a clean brush or brush, or you can use a cosmetic brush to dip pollen, and each flower should be dipped to assist pollination.

The second method is to pat the flower branches gently when the tomatoes bloom, and let these pollen pollinate each other through vibration. This is also a simple method. The best pollination time is before ten o'clock in the morning, and it is sunny.

The third is to spray plant hormones such as zuoguoling for pollination. Many friends may have some misunderstandings about plant hormones. In fact, it is a substance that exists in plants and promotes flowering and fruiting. If it is in a high temperature and high humidity environment, you need to use Zuoguoling to protect flowers and fruits.

Third, increase the sweetness.

In order to grow delicious tomatoes, on the one hand, we should do a good job in plant management, on the other hand, we should pay attention to the use of fertilizers, especially potassium fertilizer. After tomatoes bear fruit, sesame cake fertilizer after full fermentation can be used, which has comprehensive nutrition and can improve the sugar content of tomatoes.

There is also a common formula. After the tomato blooms, it is sprayed with 50 grams of potassium dihydrogen phosphate and 80~ 100 grams of glucose. Spraying leaves before fruiting, and spraying leaves and fruits after fruiting. After the first ear, the second ear and the third ear can be appropriately increased. By supplementing potassium fertilizer, not only the yield increased, but also the sugar content increased. When planting in the open field, the dosage of glucose or brown sugar should not be too large.

Fourth, pay attention to the prevention and control of pests and diseases.

There is no need to worry about pollination when planting tomatoes in the open air, but pests and diseases will increase, especially in summer when it is hot and rainy, which is the high incidence period of virus diseases, and farmers need to take precautions in advance. Morphine hydrochloride and aminoglycoside can be used. Pests are mainly whiteflies, which can also spread viral diseases. Thiamethoxam, acetamiprid and spiroethyl can be used to control pests.

Balcony planting and open planting have their own advantages and disadvantages. I hope that farmers can pay attention to the above four problems when planting tomatoes, and they can also grow delicious tomatoes at home.
