Three methods to avoid rotten flowers

A "small flower" improves the resistance to disease and stress of flowers. "Small flowers" have small, thick petals and strong resistance to diseases, so the "small flowers" of loofah are better. If you want to chant "small flowers", you should pay special attention to the time spent on flowering. Usually, flowers are planted between 10 a.m. and 1 p.m., and the young ones are small. The petal that comes out is small, and the disease resistance is strong. After 3:00 p.m. The flowers are generally large in petals.

The second is to release the air in different stages, and prevent the flowers from drying twice in a row. The first time after pulling the straw curtain for an hour, a small tuyere is opened. Generally, the air outlet is closed after 5-10 minutes to convective air; When the shed temperature reached 28°C, put the second wind, this time according to the weather conditions to determine how long the specific release. And do not open the vent all at once, avoid "flashing" the flowers and cause the flowers to dry. Step by step, gradually increase the outlet.

Third, early prevention of burnt flowers: The edge of the petal is dry and dry (different from water burnt flowers). The entire petal is not fresh. This may be a manifestation of the disease on the flowers. In the case of low light, heaviness occurs, especially after the cloudy days. Can be sprayed 25% to 100 grams of EC 1000 times or 25% PM with 1500 times the control of amine EC. Water Burning Symptoms: From the edge of the petals, water rot appears. In severe cases, the petals show symptoms of dripping, sometimes odor, and sometimes no white mold.
