The weather is cloudy, sunny and changeable, and vegetables are frequently damaged and there are ways to maintain them
Wilting vegetables Continuous cloudy days, long-term closed shed heat preservation, high humidity in the shed, low leaf transpiration, weakened root activity of the plant, and reduced absorption function. After a sudden sunny day, the leaf transpiration increases, and the water absorbed by the root system cannot meet the transpiration demand of the leaf, resulting in wilting. At the same time, after a sunny day, the heat preservation is too urgent, the air volume is large, and the nutrient transportation functions of the above ground and underground are not coordinated. The nutrients absorbed by the root system cannot be supplied to the leaves in time, causing the leaves to wilt. Air hazard First, the manure is not mature and burns the seedlings. The use of incompletely decomposed organic fertilizers will cause vegetable burning roots and fumigation, and this situation may also occur when a large amount of semi-decomposed or mostly semi-decomposed organic fertilizers are used. If the amount of organic fertilizer that is not completely decomposed is large, and the plowing is shallow, a large amount of manure is concentrated on the shallow surface, and the decomposing process is accelerated under the conditions of good ventilation and suitable environment, which will cause root burning and fumigation. Secondly, improper use of fertilizer can cause air damage. Before and after cloudy days, use fertilizers with higher nitrogen or sulfur content, and the sheds should be closed and ventilated for less time. After these fertilizers are decomposed, ammonia and sulfur dioxide will be produced, which will cause air damage to the bottom leaves. In addition, the non-standard use of stoves, charcoal, heating blocks, etc. in the shed may also produce harmful gases such as carbon monoxide and sulfur dioxide, leading to gas hazards. Phytotoxicity There are two reasons for the frequent occurrence of phytotoxicity: First, there are many kinds of medicines. In recent years, the types of high-incidence insect pests on vegetables have increased. At the same time, for comprehensive prevention and control, there are many types of one-time mixed pesticides, plus foliar fertilizers and regulators, which increase the probability of pesticide damage. The second is medication on cloudy days. When the weather is fine, the spraying interval is longer, usually once every 10-15 days, but in rainy weather, the humidity in the shed is high, the light is weak, the vegetable resistance is weak, the pests and diseases are easy to break out, the frequency of spraying increases, and the interval between spraying shorten. Under the premise that the metabolism of vegetables is weak, this kind of medicine is not only difficult to cure, but also vegetables are more prone to phytotoxicity. Approach It is recommended that when encountering the above situation, the vegetable grower should judge the symptoms in time and relieve the symptoms. At the same time, in the management process, vegetable farmers should also pay attention to the following aspects: First, strengthen ventilation. Problems such as wilting, air damage, and phytotoxicity are all related to the long-term lack of ventilation in the shed. Therefore, the most important thing in the management of the shed is reasonable ventilation. Second, strengthen root promotion. The current ground temperature is low and the root activity is poor. After vegetables are damaged, the absorption function will decrease. At this time, care should be taken to promote roots and ensure nutrient supply. It is recommended to use monosilicic acid, chitin, alginic acid and other flushing applications in advance to improve the soil and promote rooting. At the same time, vegetable farmers should appropriately raise the night temperature and use high-nitrogen water-soluble fertilizer to accelerate plant growth. Third, raise leaves. The damage to the blades caused by air damage is ******. It is necessary to maintain the blades at the fastest speed, improve the resistance to stress, and reduce the degree of damage. It is recommended to spray Bihu, Aiduoshou and foliar fertilizer containing seaweed and chitin immediately after the leaves are damaged to repair the damaged cells.

Come see who can help you lose weight?
1. Green Tea Extract: This is one of the most common weight loss extracts. It contains caffeine and catechins, which can boost metabolism, increase fat oxidation, and even improve insulin activity.
2. Garcinia Cambogia Extract: Derived from a tropical fruit, this extract contains hydroxycitric acid (HCA) which is believed to block an enzyme that your body uses to make fat and it raises levels of the brain chemical serotonin, which could make you feel less hungry.
3. Raspberry Ketones: This is a substance found in raspberries, which is responsible for their distinct smell. A synthetic version of it is sold as a weight loss supplement. It is believed to increase levels of adiponectin, a hormone that helps to regulate metabolism.
4. Glucomannan: This is extracted from the konjac plant. It's a type of fiber that can absorb water and form a gel, which can help you feel fuller and eat less.
5. Green Coffee Bean Extract: It is derived from unroasted coffee beans and contains caffeine and other beneficial compounds. It's believed to reduce the absorption of carbohydrates, which can lead to weight loss.
6. Forskolin: This is an extract from a plant in the mint family, claimed to be effective for losing weight. It is believed to create enzymes called lipase and adenylate cyclase, which free fatty acids from the body's cells.
7. Bitter Orange / Synephrine: Bitter orange contains a compound called synephrine, which may boost metabolism and encourage weight loss. However, it can also have serious side effects like high blood pressure and heart-related complications.
Always remember, while these extracts can help in weight loss, they are most effective when combined with a balanced diet and regular exercise. Also, it's important to talk to a healthcare provider before starting any weight loss supplement regimen, as they can have side effects
