The current high temperature and rainy season, the temperature is often as high as 35 °C or more, not suitable for the growth and development of tomatoes, pollination will occur physiological barriers, it is difficult to set up fruit, pests and diseases are also very serious, so need to prevent high temperatures, do a good job over the summer management.
1. Keep the film and dig drains to prevent rain and water. The top air outlet and the bottom air outlet are opened so that the air in the shed can be convectively flowed, and the hot air can be promptly removed to reduce the temperature and air humidity in the shed. In addition, the film has been aged and contaminated, and the light transmittance has dropped to about 50%, which can play a role in sunshading and cooling. The temperature in the shed can be reduced by about 3° C. than the temperature outside the shed and maintained within a suitable temperature range suitable for the growth and development of the tomato. Ensure tomatoes normal pollination and fruit set.
2. Carefully rubbed buds to fight, prevent excessive growth of nutrients, cause vegetative growth greater than reproductive growth, plant length, resulting in falling flowers.
3. A large amount of organic fertilizer can be applied in the operation line, 60-80 kg per ditch, to promote soil ventilation, intensify root activity, increase absorption capacity, maintain robust growth, and increase the yield in autumn.
At the middle of 4.8 months, it was taken care of and controlled the vegetative growth to ensure that the young fruit grows into a large fruit before pulling out.
5. Strengthen pest control to ensure healthy growth of plants and fruits. First, set up pest control nets at the top and bottom tuyere to prevent pests from entering the greenhouse from the tuyere. If pests such as locusts, whitefly, cotton bollworm, and tobacco budworms have entered the shed and damage plants, they should be sprayed and killed promptly. Second, we must pay attention to the prevention and treatment of diseases such as leaf mold, early blight, gray mold, soft rot, and ulcer disease.
Luteolin, alias carotenoid, carotenol, phytoalexin, riboflavin, marigoldin and phytoalexin, etc., orange-yellow powder. Natural lutein is an excellent antioxidant. Lutein and zeaxanthin are the only 2 carotenoids in the eye, and the prevention of vision loss and blindness caused by age-related retinal macular degeneration is the unique function of lutein.
Natural lutein is an excellent antioxidant, can resist free radicals in the body caused by cell and organ damage, thus can prevent the body aging caused by cardiovascular sclerosis, coronary heart disease and tumor disease.
