Tomato growth cycle

The growth cycle of tomatoes is 110-170 days. Among them, the growing period is 7-9 days, the seedling stage is 40-80 days, the flowering and fruiting period is 15-30 days, and the fruiting period is 30-50 days.

Management during the growth of tomatoes:

1. Planting time

The protected land in spring was planted during the transition period of hot and cold weather from late February to early March, and the plastic film in the open field was planted during the transition period of hot and cold weather around March 20. The plant spacing of early-maturing varieties is 30 cm, the row spacing is 50 cm, and the plant spacing is about 3000 plants per mu. The mid-late maturity varieties can retain about 3500 plants per mu by single-stem pruning method and 2000 seedlings per mu by double-pruning method.

two。 Pruning and scaffolding

One is single-stem pruning, leaving only the trunk, and the lateral branches growing to 4-7 cm are all removed; the second is double-trunk pruning, leaving the lateral branches under the first inflorescence except the main stem, and all the other lateral branches are removed. In addition, tie the vine in time after pruning.

3. Reasonable flower protection

In order to prevent falling flowers and fruits, 20-30ppm Tomato Ling can be sprayed during flowering; in the middle and later stages of plant growth, the lower old leaves should be removed properly; infinite growing varieties can top after growing 4-5 sets of fruits.

4. Pest control

Including the most common and harmful diseases caused by fungi, late blight caused by viruses, bacterial wilt caused by bacteria, cotton bollworm all the year round and so on. If different pesticides are applied to different diseases, attention should also be paid to the dosage.

At present, the planting area of tomatoes is vast, and the market is relatively stable. For those who have the intention to plant, you should do a good job in risk prevention first and don't plant it blindly.
