How to prevent deformity in greenhouse tomato

The common deformed fruit in greenhouses includes many empty fruits, empty fruits, cracked fruits, rotted fruits, and sun-burning fruits. The reasons for the formation of malformed fruit are: 1) Excessive application of nitrogen fertilizer during seedling stage, overgrowth of shoots, and imbalance of crown and root ratio; 2) Nutrients consumed by tomato respiration when continuous flowering (6°C to 8°C) is encountered during flower bud differentiation. Relatively reduced, the accumulation of flower nutrients in the increase, the number of carpels formed more easily form more than ventricular malformation; Third, plant aging, when the temperature is low, poor light, flower and fruit can not be normal development, easy to form apex; four It is a high temperature in the shed, high humidity, lack of light, pollen abortion, poor fertilization, fruit pectin content is small, easy to form empty fruit; five is the lack of calcium in nutrients, easy to form cracking fruit and umbilical rot fruit; Sixth, when hormones are used in improper concentration, or when the growth of the plants is weak, empty fruit or yoghurt can also be produced. Seventhly, the removal of old leaves is too much, and it is easy to form sun-burning fruit and poorly colored fruit. In order to improve the yield of K. candel, improve the fruit quality and reduce the formation of malformed fruit, the following technical measures should be taken: 1. Pay attention to the application rate of nitrogen fertilizer in the early stage of the fertility management of tomato, and balance the application of nitrogen, phosphorus, and potassium fertilizers in flowering and fruit setting period. Boron fertilizer and calcium fertilizer. During the peak period of fruit setting, 0.5% calcium superphosphate solution or 0.7% calcium chloride and 0.005% naphthalene acetate solution can be sprayed 2 to 3 times, which can effectively prevent the production of rot and fruits. Water well to prevent excessive humidity or dry soil. Second, heat preservation and anti-freezing cold wave comes, there are promptly stamped straw or in the greenhouse to take low bow film insulation to prevent freezing damage. When the weather is fine, we must uncover the straw curtains, increase the light area as much as possible, increase the photosynthetic intensity and photosynthetic efficiency, and do so. Third, scientifically controlling the growth and development of fertility tomato plants can be controlled by humans. First, when the seedlings grow too profusely, 75 mg/kg paclobutrazol solution can be sprayed to control the length. The second is to wipe off the buds properly, sparsely flowering, and remove the deformed young fruit in time. During the topping, two young leaves should be kept at the top of the heart to protect the fruit and prevent burning of the young fruit. The third is to use hormones to protect the fruit, and the concentration should not be too high, and do not repeat the application.

Anti-wrinkle Ingredient

Anti-wrinkle ingredients are those active substances that can help slow the skin aging process, fade wrinkles that have formed, or prevent the development of new wrinkles. These ingredients generally achieve their anti-wrinkle effect by promoting collagen and elastin synthesis, increasing skin moisture, antioxidants, and promoting skin cell regeneration.

Here are some common anti-wrinkle ingredients

1. Hyaluronic acid

A naturally occurring polysaccharide substance in the human body, with excellent moisturizing properties, can attract and lock a lot of water, make the skin appear full and reduce fine lines.

2. Peptides (such as pentapeptides and hexapeptides)

Small molecular protein fragments that can stimulate the production of collagen, reduce the depth of expression lines and wrinkles, and have a certain anti-inflammatory effect.

3. Retinol (vitamin A alcohol)

Widely considered to be one of the most effective anti-wrinkle ingredients, it can promote skin cell renewal, increase skin thickness, reduce fine lines and wrinkles, and improve skin texture.

4. Vitamin C (ascorbic acid)

Powerful antioxidant, can promote collagen synthesis, reduce UV damage, lighten skin, and fight wrinkles caused by light aging.

5. Nicotinamide (nicotinamide)

A form of vitamin B3, which can enhance skin barrier function, reduce water loss, reduce color spots, and have a certain anti-wrinkle effect.

6. Coenzyme Q10

A powerful antioxidant that protects the skin from free radical damage, promotes cellular energy production, and helps maintain skin elasticity and firmness.

7. Tea polyphenols(especially green tea extract)

It has antioxidant and anti-inflammatory effects, can help resist environmental stress on the skin damage, slow the skin aging process.

8. Seaweed extract

Rich in a variety of minerals, Amino Acids and vitamins, can provide moisturizing, antioxidant and promote skin repair function, help reduce wrinkles.

When choosing products containing these ingredients, you should decide according to your skin type and specific needs, and pay attention to the method of use and possible side effects of the product, especially retinol products, which may cause skin sensitivity or dryness during initial use, and need to gradually establish tolerance. In addition, continuous sun protection is also one of the important measures to prevent wrinkles.
