Identification of common confounding symptoms in rice
1. Several kinds of Ralstonia solanacearum 1. Sclerotinia sclerotiorum. It is more common in the late stage of late rice, which often occurs in clumps in the field, and there are several plants in a hole. The tissue at the base of rice is soft rotten and has dark brown spots. Peeling off the basal leaf sheath and stem, we can see that there are many black sclerotia smaller than amaranth seeds. 2. Bacterial base rot and wilt. Sporadic occurrence in the field, generally 1 in 1 point, 3 plants fell ill, the base of the diseased plant showed rat gray rot, the root system was rare and decayed, peeled off the basal stem, full of smelly water, sterile sclerotia. 3. Physiologically withered. The stem of rice plant shrinks and the base of rice stem is pinched by hand.

Cultivation of Auricularia auricula in rice straw sand bed
Fungus mites, commonly known as "fungus lice", belong to the phylum Arachnida, Arachnida and Acarina, which is not only the most harmful to edible mushroom seed production and cultivation, but also harmful to personnel. Its harm is divided into three aspects: first, bacterial mites directly feed on hyphae, resulting in no bacteria after inoculation or "disinfection" after inoculation, resulting in culture.
