Do these six points in time to prevent premature aging!
1 clearing the ditch to prevent moisture damage
In the summer, there is plenty of rain and it is necessary to do timely drainage work. Especially for low-lying fields, pay special attention to this. Excessive water accumulation, too much soil moisture, high groundwater level, will cause root hypoxia, causing roots, resulting in poor plant growth and development.
2 adequate fertilization, reasonable ratio
The bottom fertilizer must be sufficient, especially the seedlings, flowering, maturity, and even the first batch of harvesting, all need to do a good job of topdressing. The supplement of reasonable proportioning elements can restore the vigor of the plants, increase the yield of the second batch of fruits, and also prevent the premature aging.
3 timely watering, timely cultivating
The weather is hot and watering is a must. In addition to hydrating, it can also reduce soil temperature, air temperature, and blade temperature. After the rain, timely cultivating, in order to avoid soil compaction, can also play a role in maintaining moisture and oxygen.
4 choose the right time, correct topping
Correct topping eliminates the top edge and promotes balanced growth of the plant. It is generally carried out according to the density after harvesting the first loquat fruit. When picking the heart, the sick, disabled, and dead leaves should be taken out of the field to prevent pests and diseases.
5 timely harvest, mention the morning market
Timely harvesting can not only produce a bumper harvest, but also increase economic efficiency.
6 Effective prevention and control of pests and diseases
Botrytis cinerea can be sprayed with 75% chlorothalonil WP 600-800 times or 50% keeling WP 2000 times. Eggplant immune disease can be sprayed with 75% chlorothalonil 700 times solution or 80% mancozeb 500 times solution at the beginning of the disease, spraying once every 7-10 days, even spraying 3 times.
The above is a few points to prevent premature aging of vegetables. It is hoped that farmers should pay attention when planting. The premature aging of solanes and vegetables is also an important factor affecting yield. During the high temperature and rainy season in summer, the solanaceous vegetables are prone to premature aging. The symptoms are: plant atrophy, yellowing of leaves, late fruit ripening, low yield, and serious premature death of plants.
