Vegetable planting management guide in July

July is the hot and humid summer season, which brings both challenges and opportunities to vegetable growers. In order to ensure the healthy growth and yield of vegetables, some key management techniques should be mastered. The following guidelines are briefly shared with you.

1. Variety selection

You can choose some high temperature resistant vegetable varieties, such as cowpea, amaranth, water spinach , etc. These vegetable plants can adapt to high temperature environments relatively well, and can still maintain normal growth and development if planted in July.

2. Seedling raising and sowing

Cabbage, Chinese cabbage seedlings, lettuce, spinach, amaranth , celery, basella , radish and other vegetables are sown directly in the open field in batches and stages. Autumn cucumbers, autumn gourds, autumn tomatoes, autumn peppers, autumn watermelons, autumn melons, cowpeas, cabbage, cauliflower, and early-maturing Chinese cabbage can be grown in nutrient pots.

3. Field management

In the high temperature season, transpiration is strong. After sowing, the soil should be kept moist to facilitate germination. When the land is dry, water should be applied in time in the morning and evening in combination with topdressing. In low-lying areas, waterlogging should be prevented to maintain sufficient supply of fertilizer and water to the soil. For vegetables such as melons grown on trellises and eggplants, attention should be paid to timely removal of old, diseased and residual leaves from the lower part of the plant. For vegetables planted in rows, attention should be paid to inter-row cultivation and weeding.

4. Improve ventilation

During the high temperatures in July, it is very important to properly manage ventilation for vegetables. Firstly, the temperature in the greenhouse can be lowered to prevent sunburn by using sunshade nets, cooling agents or mud. Secondly, the roof and lower vents can be fully opened to promote circulation, and a 40-mesh insect-proof net can be installed to prevent insect invasion.

5. Pest and disease control

The hot and rainy weather conditions in July are likely to cause outbreaks of pests and diseases, so farmers need to strengthen their monitoring and prevention of pests and diseases. Once pests and diseases are discovered, timely measures should be taken to control them to prevent the disease from spreading.

6. Disaster relief

Typhoons are frequent in July, so eggplant and solanaceous vegetables need to be harvested in advance and mature fruits need to be picked and removed to reduce density and prevent lodging. After the disaster, tidy up the trellises, clean up the damaged plants, and ensure the normal growth of healthy plants. At the same time, spray boron fertilizer on the leaves to enhance the plant's ability to pollinate and fertilize and prevent flowers and fruits from falling.

The above is an introduction to the vegetable planting management guide for July. Through the above comprehensive management measures, the impact of high temperature and high humidity weather on vegetable production can be effectively reduced, ensuring the normal growth and yield of vegetables.
