Bean storage measures

First, the choice of species. Choose varieties with strong disease resistance, fewer fibers, good quality, and good commercial quality. Second, timely harvest. It is generally harvested when the pods have just grown and the pods have not hardened. If the harvesting is too late, the kidney bean fiber will be more, and the quality will be reduced. If the harvesting is too early, the beans will not survive the storage. Third, packaging, anti-corrosion. The beans are generally stored in 0.1 mm thick polyethylene film bags (5 kg per bag). With slaked lime 0.5 kg ~ 1 kg and sec-butylamine 0.01 ml / l (by volume) fumigation preservation. Fourth, storage measures (a) temperature. Appropriate storage temperature is an important prerequisite for controlling rust and decay. 8 °C is the critical temperature of rust produced by kidney beans. Below this temperature, the rust spot is heavy. Above this temperature, rust spots are no longer related to temperature, but are highly positively correlated with bean rot. If the bean storage period is maintained for more than 30 days, the storage temperature should be controlled at 8 ~ 10 °C. (b) Relative humidity. The relative humidity is maintained at 90% to 95%, which helps to keep the beans fresh. (c) Carbon dioxide concentration. The carbon dioxide concentration in the bag should be less than 2%. V. Notes on Caves (1) Lay beans should be packed strictly according to the maturity level when they are stored. (b) Before the beans are stored, they should be disinfected.
