What is agaric vegetable?

Auricularia auricula (scientific name: Gynura cusimbua), also known as babbling, sunflower, tofu, purple horn leaves, chrysanthemum Panax notoginseng, perennial tall herbs, 1.5-2 meters high. Flowering and fruiting period is from September to October. Auricularia auricula vegetables are fed by seedlings, tender shoots or tender leaves, with tender and smooth texture and high nutritional value. Can be used for soup, stir-fry, hot food, cold, etc., its taste is fragrant, chewing like eating fungus generally crisp and refreshing, hence the name agaric dish. It is widely cultivated in the south and north, perennial cultivation in the tropical areas of the south, and annual cultivation in the north. Leaves contain a variety of vitamins and calcium, iron, can be used as cultivated vegetables, but also ornamental. The whole herb is used as a laxative and has the effect of slippery intestines, heat dissipation, defecation and defecation; flower juice has the effect of clearing blood and detoxification, can detoxify acne, external application to treat carbuncle and nipple rupture. Fruit juice can be used as a harmless food colorant.

Common diseases of Auricularia auricula

1. Brown spot: for harmful leaves, the disease spot is nearly round, the size varies from sorghum grain to soybean grain, the edge is purple-brown, and the boundary is clear; the middle part of the disease spot is yellow-white to yellow-brown, slightly sunken and thin, some are easy to perforate, and in serious cases, the whole leaf is covered with disease spots and loses its edible value. The mycelium and conidia overwintered in the soil with the disease residue, and in the second year, the conidia were infected by conidia, and the spores produced in the disease part were transmitted and re-infected by airflow and Rain Water sputtering. Humidity is the decisive factor for the occurrence and expansion of the disease, and the disease is serious in the places where there is rain leakage in the protected area.

2. Botrytis cinerea: it mainly occurs on leaves and petioles, and develops rapidly under suitable temperature and humidity. The leaves are wilting and rotten, the stem is chlorotic and watery, the posterior stem is easy to break or rot, and the diseased part is easy to appear gray mold layer. High humidity and low temperature are the main factors causing the occurrence and spread of Botrytis cinerea. Too dense plants and too much nitrogen fertilizer are suitable for the reproduction of the bacteria, and the disease is also serious. The mycelium or mycelium of the pathogen overwintered in the disabled body, and some conidia attached to the seed surface or the mycelium latent in the seed coat overwintered. In the following year, the mycelium produced conidia spread through air flow and caused primary infection. Agricultural operation is also one of the ways of transmission.

3. Mosaic disease: the disease occurred in the whole plant, the leaves of the diseased plants became smaller and wrinkled, the leaf surface was bubbly, the dorsal veins of the leaves were obviously raised, even deformed and bent, and the plants with early onset were obviously dwarfed. It is generally caused by tobacco mosaic virus and is transmitted by contact. As long as the sap of the virus touches a slightly injured leaf, it can spread the infection.

Prevention and treatment of common diseases of Auricularia auricula

First, integrated control: appropriate close planting, 1 meter wide border strip sowing or sowing 5 rows, plant spacing 20 cm. Ecological control and timely ventilation and humidity reduction should be adopted in the protected land to avoid excessive watering or excessive application of nitrogen fertilizer. After picking, topdressing fertilizer in time, foliar spraying yield-increasing bacteria, phytin, etc., to promote the early growth and rapid development of plants and increase the yield.

2. Chemical control: 10% Chlorothalonil 250g / mu or 5% Chlorothalonil dust 1 kg / mu can be applied in the protected area, or 6.5% metachlorin dust and 65% carbendazim wettable powder 1000-1500 times are sprayed at the initial stage of the disease, or 75% chlorothalonil wettable powder 1000 times plus 70% methyl thiophanate wettable powder 1000 times. To prevent and cure virus diseases, aphids should be eliminated as soon as possible, spray with 50% aphid mist wettable powder 2500-3000 times, and spray 20% virus A wettable powder 500 times every 7 days for the first time.

Nutritional value and efficacy of auricularia auricula

4. Treat cold and damp waist and leg pain.

5. Gynecological diseases such as uterine bleeding and amenorrhea.

6. Improve anemia and osteoporosis.

7. Reduce fat and lose weight.

Auricularia auricula vegetables may not be eaten by many people, but its market space is still quite large, and there are also many people who grow Auricularia auricula vegetables. In the process of planting Auricularia auricula vegetables, the prevention and treatment of its diseases are very important. Only by reducing the erosion of insect pests can it effectively increase its yield.
