How to prevent wheat frost

Wheat frost falls below 0°C in the ground and falls below the minimum temperature that wheat can withstand in a certain developmental stage, causing wheat to suffer freezing injury. After the jointing of wheat, the cold-resistance ability gradually weakens, and it is vulnerable to frost damage. From the external shape of the plants, some of the wheat damaged by frost may be damaged by the stem, some may turn yellow and twisted, and the plants may wither. They may also cause the male and female of the panicle. The core is frozen and the floret is degraded. The seed setting rate is reduced and the yield is affected. Therefore, to strengthen forecasting and defense, the common method is as follows: The role of irrigation anti-frost frost: The first is the water temperature of irrigation, which is higher than the soil temperature when the frost occurs, and is sometimes higher than 10°C. Therefore, irrigation before frost can bring a lot of heat. Secondly, the soil moisture after irrigation increases the thermal conductivity of the soil, which can increase the heat in the lower layer of the soil. Third, because the potential capacity of the water is much larger than that of the air and the soil, the temperature of the ground can be reduced after flooding to avoid sudden heat Fourth, after the water is poured, the moisture in the air near the ground increases, and latent heat may occur when condensation occurs. In areas with sprinkling conditions, spraying water in the event of frost and adjusting the microclimate in the field are very effective in preventing frost. According to the investigation, before the occurrence of frost, the ground temperature can be increased by 1°C to 3°C, the maximum value is 4.1°C, and the temperature of the foliage is increased by 0.2°C to 0.7°C. The frost damage is significantly reduced. Smoked tobacco has a long history of application of firewood smoke protection cream. In areas with insufficient fuel, smoking agents can be used. The agent is a mixture of ammonium nitrate, residue and sawdust. The time for smoking must be mastered. It should not be too early or too late. In general, when the temperature of the leaf surface drops to 1°C higher than the frost index, smoke will start to appear. To release the cigarette lighter time and ensure the quality, good results can be obtained. The use of frost-tolerant varieties in areas prone to frost is generally caused by night frosts. Therefore, it is necessary to select and match the cold-tolerant varieties that are planted late in the festival. Because the early jointing varieties are susceptible to freezing damage, the late jointing varieties come in the form of late frosts and show strong cold resistance and light freezing injury.

Squid Strip

Squid, also known as soft fish and calamari, has high nutritional value and is precious seafood. It is basically the same nutritional function as soft brachiopods such as cuttlefish and octopus. They are foods rich in protein, calcium, phosphorus, iron, etc., and rich in trace elements such as selenium, iodine, manganese, and copper.
