Internationally, regular intake of shiitake mushrooms can prevent rickets, which has been recognized in many countries, especially infant rickets, because vitamin D deficiency can cause phosphorus and calcium metabolism disorders. Shiitake contains provitamin ergosterol, which is not found in large amounts in vegetables, but it can be converted to vitamin D in the sun. Vitamin D can increase resistance to diseases and prevent and treat colds. Here we particularly mention the hepatoprotective effect of shiitake mushrooms, as they also contain adenine and choline, which can prevent the occurrence of cirrhosis and vascular sclerosis. In addition, tyrosinase contained in shiitake mushrooms tends to lower blood pressure.

Root rot. Is a fungal disease, after onset, the most obvious feature is that the leaf margins of the lower leaves of the plant become darker, and the whole leaf becomes dark and scorch when it is severe, which can reduce the production of broad beans by 30% to 50%. In terms of prevention and control, if the disease has already occurred, it can be timely mixed with phosphorous and potassium fertilizers or a ditch for burying in ash manure, and use 50% carbendazim or 70% thiophanate-methyl 1000-times liquid leaching, which has a good control effect. .
Red spot disease. In the early stage of disease, small red spots appear on the leaves, and then gradually expand into round red spots. In warm and humid winter and spring, the lesions expand rapidly, the diseased leaves become withered, and finally die. Prevention and treatment of the disease should be taken to prevent the disease by taking rotations, draining water, adding phosphorus and potassium fertilizers, or using tree ash, fire and earth ash. Chemical control can be sprayed with 50% carbendazim 100 g or 70% thiophanate-methyl 70-g water 50 kg.
Rust. In winter and spring, the disease is more severe in warm and humid weather. First invade the old leaves of the base, and then invade the stems and calyx of the young leaves. After onset, it is generally possible to reduce the production of faba bean by 10% to 20%. After the pups become victimized, they become black and partially rot. It is difficult to sell fresh faba bean, affecting the yield and affecting the quality. In the prevention and control, the diseased plants should be promptly removed and burned with triadimefon 600?800. The liquid was sprayed at the early stage of the disease, and the effect was best when it was controlled 1 to 2 times. Combined with the removal of the top heart of the broad bean, it can promote the growth of more beans.
In addition, there is a blight of dead stem disease, which is a physiological disease caused by waterlogging. There is more rain in spring, especially in the case of faba bean flowering and podging. In case of rainy weather, poor drainage leads to root rot. Attention should be paid to clearing gutter drainage in order to reduce rhizosphere water damage.
Broad bean is an important crop of winter grain and fertilizer in our province. At present, it has gradually entered the period of flowering and podging. It is the key period for preventing and controlling high-yield diseases of broad bean varieties. Its main diseases are:
