Pest control during Chinese cabbage cultivation
At present, it is the planting period of Chinese cabbage, and conscientiously do a good job in the prevention and control of pests and diseases during the sowing of Chinese cabbage. It is the key to implementing the “preservation-based, comprehensive prevention and control†plant protection policy to prevent problems before they occur. Because this year's precipitation is more than normal, the temperature conditions are suitable for the main pests and diseases of Chinese cabbage such as: bacterial diseases, aphids, beet armyworms. Farmers are expected to do a good job in the prevention and control of pests and diseases during the cultivation of Chinese cabbage, laying a good foundation for the high yield and harvest of Chinese cabbage. The following prevention methods are proposed:
First, strengthen field management:
1. Select resistant varieties, such as autumn green 75, autumn green 60, autumn green 55 and so on.
2, we must pay attention to clean the countryside, level the land, intensive cultivation.
3, suitable for late broadcast, should try to choose the terrain of high dry land, avoid low-lying, conditional areas to promote sorghum and small sorghum cultivation methods.
4, strengthen the management of fertilizer and water, to apply fully decomposed organic fertilizer, watering should be based on weather and soil temperature, to avoid flooding, flooding in time.
Second, pay attention to pest control:
1. To control the soft rot of Chinese cabbage, 10 million units of agricultural streptomycin 4000 times solution can be used; 70% dikesone 500-1000 times solution.
2, prevention and control of Chinese cabbage downy mildew, available 64% anti-virus 矾 M8500 times liquid, Fuxing 1000 ~ 1200 times liquid.
3, Chinese cabbage soft rot and downy mildew mixed plots can be used agricultural streptomycin 4000 times solution plus 40% phreek 200 times liquid spray.
4, prevention and control of Chinese cabbage dry heart disease can be sprayed in the seedling stage, rosette period and the core period before the spraying type "control Feng" every 450 grams of water 50 kg.
5, prevention and control of Chinese cabbage virus disease, in the early stage of onset or onset, the use of bacteria gram grams of 180 ~ 240 ml, diluted into 200 ~ 260 times liquid spray, appropriate reduction in seedling period, continuous spraying 2 to 3 times, interval 7 to 10 days.
