Are the tomatoes ripe in autumn?

Tomatoes generally ripen in summer, June-August and autumn 10- 1 1.

When planting spring tomatoes, the seedlings are generally older, and they are usually watered slowly until the first ear is set. In summer and autumn, tomato seedlings are young when planted. After the seedlings are delayed, it is necessary to promote the rapid growth of seedlings, water them in time, and pay attention to intertillage after watering. During flowering, the squatting seedlings are rarely watered unless the drought is severe. In this period, the main purpose is to keep the soil loose and the surface dry, promote strong seedlings, ensure the root system to expand downwards, and lay a good foundation for the vigorous growth of plants in the future.

When the fruit urging water sits for 2-3 times in the first ear, water it in time to urge the fruit, and pay attention to the watering time. If watered early, plants tend to grow vigorously, and the nutritional growth is too strong, so it is not easy to set fruit or the fruit-setting period is postponed. After watering, the growth of plants will be hindered. Although there are many fruits, the leaves will become smaller, the growth will be slow and the yield will be reduced.

Watering is carried out after the first ear of fruit is in full fruit stage. At this time, the tomato gradually entered the flowering and fruiting stage, and the fruit expanded and matured. The growth of plants is large, and the water demand of various organs is large. Generally, water is poured every 5-6 days in the early stage of fruiting to make the ground wet and dry. Shallow hoeing can be carried out after watering, otherwise continuous watering will easily lead to floor hardening and large evaporation.

At this time, watering is to keep the soil moist and meet the needs of plants to absorb water. In addition, it can improve the air humidity between the ground and plants. Before and after noon in dry weather, plants can be sprayed with sprinkler irrigation or water when conditions permit, so as to reduce the leaf surface temperature and reduce the occurrence of sunburn and virus diseases.
