Matters needing attention in raising vegetable seedlings in summer

Summer is hot and hot, and it is also the peak season for vegetable planting. At this time, a large number of vegetables are on the market in autumn. In order to improve the yield and quality of vegetables, many farmers will take the way of seedling transplanting. So what should we pay attention to in raising vegetables in summer? Let's get to know it with the editor.

1. Prevent high temperature and rainstorm

In summer, not only high temperature, but also frequent torrential rain, which makes the air humidity surge, if improper drainage will also pour back into the nursery, resulting in greenhouse and facilities damage, which is not conducive to the development of seedling breeding. Therefore, when raising seedlings in summer, we must do a good job in drainage measures, check drainage facilities in advance, and repair greenhouse film in time. For high temperature, you can use internal and external shade net, water curtain, fan to shade and cool down, and when the temperature is too high, you can also spray water mist to cool down. Conditional plants, ha can buy ice to cool down.

2. Drought prevention

The soil matrix is easy to dry because of high temperature and light intensity in summer. If the soil matrix is not watered in time or the amount of water is small, the matrix is suddenly dry and wet, then it is easy to cause the harm of base rot. Should carefully observe the growth of seedlings, check the dry and wet conditions of the substrate, timely and appropriate watering, watering should also pay attention to methods, preferably in the morning and evening, as far as possible to avoid high-temperature watering at noon.

3. Guard against apprentices

Raising seedlings in summer high temperature season, day and night temperature is small, night temperature is too high, it is very easy to cause seedlings to grow, so in seedling management should pay attention to increase ventilation, timely seedling division, timely chemical spray prevention and control. This can prevent the seedling Internode from being thin and long, make the seedling stout, the leaf color thick green, the leaf thickening, and promote the flower bud differentiation of the seedling.

4. Prevention of diseases and insect pests

In high temperature season, vegetable seedlings are easy to be infected with virus diseases, and at the same time, aphids, planthoppers and other insect pests will be produced, so preventive maturity should be taken. First of all, the virus-resistant varieties should be selected before sowing. The seeds can be soaked in 1000-fold solution of 10% trisodium phosphate for 10 minutes before sowing, and then rinse the seeds with clean water to eliminate the germs and viruses carried by the seeds and improve the germination rate of the seeds. In the process of growth, 60 mesh insect control net can be used to control aphids and aphid wasps can be used to control planthoppers.
