Wheat seed storage technology
When wheat is harvested, it is in a hot and humid climate. Even if it is fully dried, improper management may result in hygroscopic resurgence, insects, fever, mildew, and difficult storage. Therefore, it is necessary to grasp the key points of wheat seed storage technology. 1. Strictly control the moisture of seed storage The length of wheat seed storage depends on the seed moisture, temperature and humidity resistance of the storage equipment. According to local experiments, the seed moisture does not exceed 12%. If it can prevent moisture absorption, the seed can be stored for a longer period of time without using insects. , No mildew, no reduction in germination rate; if the moisture is 13% and the seed temperature reaches 30°C, the germination rate will decrease; the moisture content will be 14-14.5% and the seed temperature will rise to 21-23°C if it is poorly managed. There is a high possibility of mildew; moisture is 16%, and even if the seed temperature is 20°C, there is still a lot of mildew. Therefore, the moisture during storage should be controlled below 10% and the seed temperature should not exceed 25°C. 2, after the sun hot storage into the insecticidal storage Wheat seeds have strong heat resistance, and they can use this feature to heat the seeds and heat them into the warehouse, which can not only achieve the purpose of killing insects, but also accelerate the passage of the wheat seeds through the eyes. The specific approach is: Select the sunny weather will wheat seed exposure, so that the species temperature above 46 °C degrees and not more than 52 °C, and then quickly warehouse stacked, covering the surface layer, and the doors and windows sealed insulation, so that the continuous high temperature closed 7- After 10 days, ventilation cooling was performed to bring the seed temperature down to a temperature similar to that of the storage and then to conventional storage. The method should be used to grasp the temperature during the incubation should not be too high, the seed moisture must be less than 12%, but also need to try to prevent the ground and the seed temperature is too large and cause the underlying condensation; for the dormant seeds, due to heat resistance The weakening is generally not suitable for this method. 3, using closed moisture storage According to the characteristics of strong hygroscopicity of the wheat seeds, the seeds should be tightly sealed during storage to prevent outside water vapor from entering the warehouse. In addition to the closed doors and windows, the mat can be covered with mats or sacks, etc., and the glands should be flat, tight and pressed. In fact, conditional, with 10-15cm dry pond ash cover, both pest and moisture. For a small amount, the seeds can be stored by means of pots, enamels, altars, jars, etc., which are glazed with internal and external walls. The seeds are fully dried before storage and sealed after storage. A layer of dry ash is placed on the bottom of the container and the seed surface. Advantageous, the appliance is placed in the shade of the house in the north or buried in the pool 2/3, can be stored safely for a long time. 4, regular inspection Seed temperature, moisture, germination rate, temperature and humidity of the warehouse, and insects, moths, etc. should be regularly checked during storage to ensure timely detection and handling of problems. 40m Laser Distance Meter is a functional and advanced measuring tools, no need climbing up and down, which is the engineers' best friends.
