Vegetable storage is one of the effective ways to increase the value of vegetable products. At the same time, it has increased the variety of vegetables and enriched the vegetable baskets of urban and rural residents. To this end, the storage technology under normal temperature conditions of bean is described as follows: 1. Varieties and pre-storage treatment For storage of fresh bean varieties, medium and late ripening beans are preferred: such as green dragon beans, Weifang white grains and so on. After harvesting, the harvested beans need to be rid of non-standard insects, diseased fleas, broken pods, over tender and overgrown pods, and be placed in a ventilated, shady and cool place to reduce the pod temperature and reduce the field heat. Second, the appropriate storage conditions Storage beans suitable temperature is 7 ~ 9 °C, humidity 90% ~ 95%, oxygen content of 3% ~ 5%, CO2 content of 5% ~ 15%. Third, the preservation of fresh methods to make storage accounts without drip film, the size of the account depends on the storage, generally 200kg per account storage is appropriate, accounting length is (1 ~ 1.2) m (0.8 ~ 1.0) m, account with Sterilized bamboo rods are used as supports. The welding window of the silicon window is adjusted on the book surface to adjust the humidity inside the account so as to avoid excessive humidity and cause rot. The storage containers are preferably made of plastic pipes or bamboo baskets, and the volume of the containers is 8 to 10 cm from the mouth to facilitate the circulation of gas. In the code basket, do not rely too tightly between the basket and the basket, and use a sterilized brick or wood frame under the basket. The distance between the basket and the ground is generally 5 to 10cm. There should be a gap between the basket and the basket, and there should be a gap between the basket and the inner wall of the account film. In order to prevent the formation of ethylene inside the account. Apply bricks to the bricks under the basket and soak in saturated potassium permanganate solution. The use of this technology to store beans, the general shelf life of 20 to 30 days, during the preservation period every 4 days to check once, when the bean product rate dropped to about 95%, should be timely listing.
