In the high temperature season, how to improve the stress resistance of vegetables, thereby improving the yield and quality?

In the high temperature season, improving the stress resistance of vegetables is the key to our management work. Because the high temperature season is prone to many unfavorable environments for the growth and development of vegetables, such as high temperature, drought, waterlogging, etc., which have a great impact on the yield and quality of vegetables, and the emergence of these unfavorable environments, the core problem is the resistance of vegetables. Deterioration of inverse ability. Therefore, improving the stress resistance of vegetables is an important means to improve the yield and quality of vegetables.

Learning theory to guide practice - what is the resilience of vegetables?

The so-called resilience refers to the resistance of vegetables to the adverse external environment. In summer, these adverse environments include high temperature, drought, waterlogging, cloudy and rainy days, and even windy weather, etc. As long as there is an adverse environment, the growth of vegetables will definitely be affected, and the biggest impact is the excessive consumption of organic vegetables. Nutrition. To put it simply, organic nutrition refers to the carbohydrates produced by leaves through photosynthesis, not the nitrogen, phosphorus, potassium, medium and trace elements we apply, nor amino acids, humic acids and other fertilizers. These are mineral nutrients.

Organic nutrition is a key factor in the growth of vegetables, because the growth of vegetables is all through the accumulation of organic nutrients. As long as there is an unfavorable environment, vegetables will consume their own organic nutrients to resist this unfavorable environment, and will inevitably reduce their own accumulation of organic nutrients. There will be weak growth and physiological diseases.

For example, tomato and umbilical rot are known to be calcium deficiency, but calcium deficiency is a direct manifestation of it. What causes calcium deficiency? A very important reason is the poor resistance to stress; when the temperature is particularly high, the cucumber grows with the tip and dries out, and the leaves begin to dry out. This is called the physiological dry tip, which is caused by the poor resistance to high temperature; these problems The occurrence of the disease is first related to the lack of trace elements, but the most fundamental reason is the occurrence of physiological diseases due to poor stress resistance.

In short, no matter what kind of unfavorable environment, it will ultimately affect the yield and quality of vegetables.

Supplementation of medium and trace element fertilizers

In summer, special attention should be paid to the supplementation of medium and trace element fertilizers, including calcium, magnesium, zinc, boron and so on. Through the supplementation of medium and trace element fertilizers, a comprehensive balance of nutrients can be achieved and the stress resistance of vegetables can be improved. As long as the nutrients are balanced, the stress resistance will naturally be improved, especially calcium fertilizers, which should be paid special attention to in the high temperature season in summer. Almost all vegetables, All like calcium.

Supplement with organic nutrition

The poor resistance to stress is due to the lack of organic nutrition. Therefore, supplementing organic nutrition is the core. Therefore, the supplement of organic nutrition is the most direct measure to improve the resistance to stress. After adverse environmental effects, foliar sprays of anti-stress and

Summary: The poor environmental resistance of vegetable crops is the incentive. After understanding the real reasons for the poor resistance of vegetables, and taking the above management measures, both the yield and quality of vegetables will be greatly improved.
