How to prevent premature aging of nightshade vegetables

Common symptoms of premature aging in nightshade vegetables are: atrophy of plants, yellow leaves, and late maturity. The cause of premature aging is mainly high temperature and rain. The following introduces some measures to prevent premature aging.

1. Topping at the right time After picking the first stubble of the bell pepper, cut off 8 branches that grow from more than 4 large branches growing near the base. Cucumbers are topped at 25 leaves. Tomatoes are topped after the 4th ear sits, and 2 leaves are left above the ears. When old leaves, dead leaves, and diseases are removed in time, it is conducive to ventilation and cooling.

2. Timely harvesting Timely harvesting to reduce nutrient consumption and prevent premature plant senescence.

3. Timely fertilization Timely fertilization can provide sufficient nutrients for plant growth and development, which is a key measure to prevent premature aging. The best time for top dressing is to perform 1-2 times after the fruit is harvested. Combined with watering, topdressing manure and urine can also be applied, and nitrogen and phosphate fertilizers can also be applied.

4. Irrigation to cool down In the hot summer, the eggplant and vegetables can be irrigated at appropriate time according to the weather and soil moisture conditions to reduce the soil temperature and prevent premature plant aging.
