"Warm winter" is easy to induce tomato gray mold.
Control methods: Appropriate application of phosphorus and potassium fertilizers for agricultural control, improve plant disease resistance. Promote drip irrigation and under-membrane irrigation techniques to prevent flooding. At the beginning of the disease, the remaining petal and stigma should be removed in a timely manner to remove diseased leaves and diseased fruits and to remove diseased plants to prevent the spread of disease.
Ecological control aims to increase temperature and eliminate humidity and strengthen ventilation management. The specific approach is: First, close the shed to warm up in the sunny morning; when the temperature reaches 28°C~30°C, it will continue to open the top wind for one hour, continue to release the wind at noon, and maintain the temperature at 20°C~25°C. When the temperature reaches 18°C ​​to 20°C in the afternoon, the ventilation openings are closed, the night temperature is maintained at 14°C to 16°C, and the relative humidity is maintained at 70% to 80%.
Before the colonization of pesticides, 50% Suo Keling wettable powder 1500 times or 50% Carbendazim wettable powder 500 times sprayed seedlings to prevent bacteria from entering the greenhouse; at the early stage of disease, 50% Suo Keling wettable powder was used. 2000~3000 times liquid, 45% Tektronix suspension agent 3000~4000 times, spray once every 7~10 days, spray 3~4 times. Botrytis cinerea is easy to produce drug resistance, and the amount of drug and application times should be reduced as far as possible, and attention should be paid to rotation and alternation of medication.

Selenium-enriched Rice grows selenium-rich rice by selenium supplementation when rice is grown. It is a functional agricultural product and is a food rich in selenium with high nutritional value.
Selenium
is an indispensable trace element to maintain the normal function of
the human body. Selenium deficiency in the human body can lead to
various diseases. Modern scientific research
proves that selenium has anti-oxidation, enhances human immunity,
effectively removes harmful garbage, promotes human health, and delays
aging.
