In the hot and rainy weather in summer, how should vegetables be managed to achieve high yields?

It is now summer. Due to the high temperature, strong light and heavy rain in summer, it is the time when various diseases and insect pests are highly prevalent. From vegetables planted in spring to vegetables planted in summer, whether it is watering, fertilizing or Various management methods, if you don't master the methods, watering, fertilizing and managing randomly, vegetables will not only grow poorly, but also have various problems. Therefore, when managing vegetables in summer, these points must be done well, otherwise yellow leaves, stagnant growth, and dead trees will reduce production; if done well, there will be too many fruits to pick. 1. Pay attention to the time of watering

Both the ambient temperature and the soil temperature are very high in summer, especially in the afternoon to mid-afternoon on sunny days, people will feel very uncomfortable in a climate of 30 degrees. It is very hot. You must remember to water vegetables at this time. There is no need to water in the afternoon and afternoon. Because the ambient temperature of the soil is very high in the afternoon and afternoon, the rhizomes cannot breathe smoothly at this time. If you water the rhizomes, it is easy to damage the rhizomes. , it is also easy to produce various diseases.

Therefore, watering vegetables in summer should be done in the morning and early morning. Another thing, no matter what season, when watering, you must eat small amounts and eat frequently, and never flood with water. Otherwise, the rhizomes will cause root rot. 2. Fertilization must be measured

Due to the continuous high temperature in summer, rhizomes are very sensitive to the surrounding environment. Vegetables need to be fertilized during growth and development. However, unreasonable fertilization will cause damage to rhizomes. Fertilizing vegetables in summer Be sure to pay attention to these points. Do not use unfermented organic fertilizers; do not fertilize in the afternoon when the temperature is high; do not fertilize on rainy days; do not fertilize close to the rhizomes; leaf spraying should be carried out in the morning and morning; for newly planted vegetable seedlings, do not fertilize until the roots have slowed down; long beans are not fertilized at the beginning of the season. There is no need to fertilize during the flowering period. 3. Pay attention to root maintenance and mulching

Summer is the season of high incidence of various diseases and insect pests. Generally from the end of spring to autumn, dead trees, root rot, poor growth, etc. often occur, which seriously harms the health of the plant. The normal growth and development of crops results in the loss of trees and short seedlings, and the production volume is greatly reduced. Since the rhizomes are in a weakened state in summer, they are very susceptible to pathogenic bacteria. Therefore, no matter what kind of vegetables are planted, root care is a key element to ensure the healing of vegetables.

Raising roots is not as simple as watering and fertilizing randomly. It just needs to use chemical fertilizers that have the effect of growing roots. Today I will bring you a method of growing roots, nourishing roots, and preventing diseases, using mineral resources. Potassium fulvic acid + Bacillus subtilis, or alginic acid + Bacillus subtilis, mixed with organic fertilizer as fertilization or root irrigation, to grow roots and seedlings, prevent diseases, and improve efficiency. 4. Pay attention to soil permeability

There is a lot of rain in summer, and the surface layer of the soil is most likely to harden and agglomerate, which is very detrimental to root growth and development. Maintaining loose soil and air permeability is the key specific measure for root care. But many growers are also the most likely to ignore these processes. Therefore, in summer, whether after it rains or after watering, the soil should be hoeed and plowed frequently. Firstly, it can quickly evaporate the water in the soil. Secondly, drought temperatures can cut off the soil moisture. Evaporation maintains soil moisture, and thirdly it can improve soil permeability, which is beneficial to the breathing and growth of rhizomes. 5. Pay attention to the prevention and control of various pests and diseases

Due to the continuous high temperature and humidity, summer is the most serious time for pests and diseases. Vegetables such as tomatoes, peppers, green beans, etc. are prone to diseases and viral diseases. , brown spot and other diseases, once discovered, must be controlled in time. For pests, you can choose acetamiprid, trichlorfon, emamectin and other drugs. If you don’t want to use pesticides, you can choose tobacco to make tea, topdress grass ash, etc.

For diseases, you can choose targeted drugs such as aminooligosaccharides, ningnanmycin, and metalaxyl. If you don’t want to use pesticides, you can choose some biological agents. Whether it is a pest or a disease, it is important to prevent and control it in time when it is first discovered. If you wait until it becomes serious, it may be too late.
