The first is to use "small flowers" to improve the resistance to disease and stress of flowers. Loofah "flower" petals large, thin, easy to infect diseases, and "flower" petal small, thick, strong resistance, so loofah "small flowers" is 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 batches to prevent it from drying out. In two separate releases, the first time one hour after the opening of the straw curtain, a small tuyere was opened. Generally, after 5-10 minutes, the air outlet was closed to convective air, which could not only reduce the humidity of the greenhouse, but also to the shed. Add a lot of carbon dioxide inside; put the second wind when the temperature of the shed reaches 28°C, 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. The third is to prevent corruption early. Luffa rotten mainly dry burnt and water burnt two. Dry burnt-out symptoms: The edges of the petals are dry and dry (different from water burnt flowers), and the entire petals are 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% chlorpromazine EC 1500 times. 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. The author's analysis: The odor but not the hairy condition may be the bacterial soft rot disease, the longevity mold may be the flower rot disease or the cotton blight disease, both of which are heavier in the case of high humidity. Bacterial soft rot may be sprayed with streptomycin, neomycin, or sprayed with copper preparations such as chlorpyrifos. Flower rot and Bacillus diseases can be sprayed with foliar, ank, or radome and other agents.
