Improper storage of seed corn will cause the germination rate of corn seeds to decline, which will cause great losses to the farmers who produce the seeds, the corn seed acquisition companies and the farmers who use them. In order to reduce this loss, Zhang Xiaomei, a researcher of the Shanxi Academy of Agricultural Sciences, explained the storage technology of seed corn for everyone. The easy-to-appear conditions of corn seed storage: 1. Easy-to-heat corn is a large-grained, large-embryo seed that is prone to heat and causes deterioration of the seed. 2, easily rancid high temperature, high humidity easy to make corn embryos produce free fatty acids, so that the acidity increased, will affect the viability of the seed. 3, easily moldy corn seed thin, easy to produce PIP Advertising Start PIP Advertising End Mildew, causing the seeds to deteriorate. 4. It is vulnerable to freezing frost and the seed has a high water content and is subject to freezing damage, which affects the quality of the seed. For the above situation, to store corn well, you must do: First, the water content of maize with falling moisture drops to 12.5%, and can be stored for 0.5 years - 1.5 years. The viability of seeds can reach more than 99%, and the germination rate is 97% - 98%. The most effective measure to reduce seed moisture is ventilation. Ventilation can be divided into two types: 1, natural ventilation According to the inside and outside temperature and humidity, reasonable opening and closing doors and windows, the use of air convection ventilation, its effect depends on the internal and external temperature difference, wind speed, stacking methods, stack size, seed porosity and so on. When the outside temperature and outside humidity are lower than the inside of the bin, the wind speed is large, the stacking is small, and the ventilation effect is good when the porosity is large, otherwise the effect is poor. Natural ventilation requires air to circulate as long as there is a temperature difference and wind speed. For this reason, reasonable ventilation time must be selected. Measure the temperature and relative humidity inside and outside the warehouse before ventilating. When the temperature and humidity outside the warehouse are lower than that in the warehouse, ventilation is allowed; the temperature and humidity outside the warehouse are the same as those in the warehouse, and the other is lower than the warehouse. Can be ventilated; outside the temperature is lower than the warehouse, and the relative humidity is slightly higher than the warehouse, through the air into the warehouse after the relative humidity is significantly lower than the original warehouse humidity, ventilation. 2. Mechanical ventilation Blow dry cold outside air into the seed heap or suck out the hot and humid air inside the seed heap. Mechanical ventilation, a type of press-in (blowing), connecting the air outlet of the fan to the air duct, so that the external cold air is pressed into the seed pile, and the hot and humid air in the seed pile is distributed by the seed surface; the other is the suction type, Connect the vent of the fan to the air duct, and suck the hot and humid air in the seed heap out of the air duct to reach a suitable temperature and humidity. Second, there are two kinds of clever storage methods: First, the ear method, the taro ear storage, which is conducive to seed ripening and drying, reduce the risk of worms and microorganisms, but the storage capacity utilization is low. The second is the grain-collection method, which requires stricter requirements for seeds. And the pellets are prone to insects and mildew. The general relative humidity is less than 80%, and it is better to use the ear to hide. It is suitable for small-scale storage in the farmhouse. The relative humidity is more than 80%, and the grain is better. When the grain is hidden, it can be sealed with a low-temperature lid to keep the seeds at a low temperature and reduce the damage of insects and molds.
