Wheat storage method

First, the storage characteristics have a long after-ripening period, in the process of ripening, breathing is prosperous, prone to "sweat" phenomenon, so that the top of the seed heap moisture absorption, causing fever, mildew. Strong heat resistance, high temperature sealed storage, not only can prevent pests, but also maintain seed viability in a certain period of time. Through post-ripening wheat, heat resistance is reduced. Strong hygroscopicity, prone to insects, thin seed coat, soft tissue, containing a large number of hydrophilic substances, easily hygroscopic and susceptible to insects. The respiration intensity is relatively large. With the increase of the seed moisture content, the respiration intensity of the seeds increases. In wheat, the respiration intensity of wheat increases rapidly. Second, the storage method Storage of wheat seeds using dry moisture storage. After entering the warehouse, the wheat will be sealed tightly to prevent moisture absorption, and heat prevention, mildew prevention and pest control shall be done. Storage of wheat seeds, moisture content below 12%, the seed temperature does not exceed 25 °C is appropriate. Households usually use containers such as cabinets, pots, and pottery jars, while national seed warehouses use loose and bagged methods. 1. Pottery jars and pots are a simple and effective method of storing seeds. Specific storage methods: first select the pottery jars and pottery jars that do not contain acid, alkali, pesticides and chemical fertilizers, wash and dry them, place them in a dry place, and pour the dried seeds into the jars and altars, covering the dried ones. Straw ash is 15 centimeters thick and then wrapped with a plastic wrap. During the period of seed storage, heavy rain and mildew are encountered. Afterwards, it must be checked in time and problems should be solved in time. Generally dried (a bite breaks into two segments prevail) seeds into the jar into the tank, from harvest storage to sowing do not need to turn over the sun. However, the seeds that enter the tank or into the altar are not dry enough and cause insects or flooding. The plastic film ruptures and leaks, or the storage period needs to be extended. The sun should be chosen to turn over and dry, and the insects should be dried to reduce the moisture to ensure safety. Glazed pottery jars and pottery jars have moisture-proof properties, and they are hard and resistant to rats. After drying, the plant ash has a certain hygroscopicity, and it covers the seeds and can prevent insects and rodents. The plastic film on the mouth can prevent water and moisture from infiltrating into the mouth, which can prevent the seeds from absorbing moisture and regain moisture, keep the dry state, and ensure that the seeds are stored for two or three years. 2. Hot storage into storage, using the characteristics of wheat heat resistance to create a method of storage of wheat seeds. This method is well-controlled and can achieve high-temperature killing without losing seed germination. Specific approach: Select the sunny weather, the exposure of wheat, so that the temperature of 46 °C or more and not more than 52 °C, and then quickly warehousing, sealed insulation, close the doors and windows can be. Do a good job of hot storage: 1. Master the dormancy characteristics of wheat seeds. Seeds that do not pass the dormancy period generally have higher heat resistance and can be fed into storage. 2 The moisture content of wheat in hot storage should be in the range of 10.5-11.5%. 3 Do a good job of airtight insulation to maintain the seed temperature above 44-47°C during the heat treatment and maintain it for 7-10 days; however, the high temperature treatment time should not be too long and it should be cooled and cooled in time to achieve the effect that neither affect the seed viability nor achieve killing. Effect of insects. 3, the number of wheat is less or for the promotion of improved varieties ready to transfer to other places in order to adopt packaging is appropriate. If the water content is below the safety standard, a non-shaped or semi-unshaped solid pile method is used, and the number of bags that can be stacked can reach 10-12 bags. Such as wheat seed moisture is higher, but also for the fall and winter cooling season, ventilation should be used to wind or cool the pile, to maintain a large gap between the sacks, to facilitate ventilation and loose bulk. The commonly used storage methods include “money hole” shape and “well word” shape, etc. The stacking height should be low, and it is generally suitable for temporary short-term preservation.
