Select suitable varieties with disease resistance, high quality and good commercial properties, such as Elian No. 4, No. 5 and New Elian No. 1, etc.

2. Soil preparation

It is appropriate to choose clay loam with deep fertile soil layer, loose soil, fertilizer and water retention. Generally, 30cm should be ploughed deep and raked flat, 4000-5000kg farm fertilizer should be applied per mu, and 48% Anze compound fertilizer 20-30kg/ mu can also be applied.

The prevention and control of corruption is serious in agriculture. Disease-resistant or disease-free varieties can be selected, crop rotation, field disinfection of 75% chlorothalonil, less application of nitrogen fertilizer, application of human feces and urine, and other measures can be taken to control the disease. Brown spot can be sprayed with 32.5% Ami Miao 1500 times liquid spray at the initial stage of the disease, and lotus root maggots can apply 5% Zidan granule 3-5 jin per mu to lotus root field after planting lotus root every year. The eggs of Spodoptera litura were sprayed with 6% Liangtai 750 times during the incubation period.
