The heart of the dish is also known as the vegetable dish, the cruciferous genus, one or two years old herb. It is suitable for sowing in warm areas of the south and is one of the specialty vegetables in southern China. It can be planted all year round and is now introduced and cultivated all over the world. First, the performance and harm of the disease on the onset of cabbage heart disease The growth temperature of mycelium of Rhizoctonia solani is 6-40 °C, and the growth temperature is 20-30%, especially at 25-30 °C. The mycelium survives in a cool, dry soil. When the soil moisture is maintained at 20%-60% of the maximum water content, its saprophytic ability is the strongest, and the occupation capacity of the substrate is significantly decreased by more than 70%, and its saprophytic ability is almost completely disappeared above 90%, which is mainly High humidity is good for bacteria in the soil. However, the germination of sclerotia requires high humidity, and the relative humidity is generally 98% to germinate. Invasion also requires a certain amount of free water or a relative humidity of nearly 100%. Soil pH has little effect on the growth of liquid bacteria. Generally, the pathogen of pH5.8-8.1 grows well, and the growth rate is significantly lower than that of PH4. At the beginning of the disease, the water-stained elliptical dark brown lesions were formed at the base of the stem of the diseased seedlings, which were slightly sunken. After 1 week of spreading around the stem, the seedlings were wilted above the diseased part, and then gradually died. The diseased seedlings are not standing down, so they are called blight. When the humidity is high, the diseased part produces a filamentous mild brown mold, that is, a pathogenic mycelium. The disease course of blight is longer than that of stumbling, and the expansion speed is slow, unlike the disease. Second, the medicament to prevent the disease The seedbed is located in a place with high ground and good drainage; the disease-free new soil is selected as the seedbed; if the old bed is used, the bed should be disinfected; the compost can be made from the organic fertilizer or the enzyme bacteria; the sowing should not be too dense, and the soil should not be over thick. Strengthen the management of the seedbed, watch the weather insulation and release the wind, the water should be supplemented several times less, pay attention to ventilation after watering. For each square meter of seedbed, use 95% of the original medicinal drug 1g to mix 15-20kg of fine soil. Spread 1/3 of the soil before sowing on the surface of the bottom water. After the broadcast, the remaining 2 will be /3 The soil is applied to the seed to cover the underlying pad so that the seed is sandwiched between the herbs. 50ml of 30% phenylthiazide emulsifiable concentrate per 667 square meters, 50kg of water, diluted to 1000 times liquid spray, can effectively prevent black root disease and can prevent the disease of cabbage. Seeding with 50% Fumex double powder with 0.3% seed weight before sowing, or spraying 30% diphenyl ether A/propyl ring emulsifiable concentrate 3000 times solution or 75% chlorothalonil WP 600 times solution after the disease is removed at the beginning of the disease. More than 60%·Fu Ke Wet Powder 500 times solution, 20% methyl chlorophosphorus emulsifiable oil 1200 times solution, 3.2% carbamide water 500 times solution, 95% carbendazim original drug 3000 times solution.
