The first cold wave of the Year of the Snake is coming fiercely, and Hubei will enter the "freezing mode", with the lowest temperature in the north between -7℃ and -4℃, and in the south between -4℃ and -1℃. In this cold weather, the wheat babies and rapeseed babies in the fields are also facing severe survival tests. How should we help them withstand this cold wave? At present, Hubei wheat is in the tillering and jointing stage, and rapeseed is in the bolting stage. These two stages are the key periods for crops to transform from vegetative growth to reproductive growth, and are extremely sensitive to environmental changes. Low temperature chilling and freezing damage may affect the reproductive differentiation of wheat and rapeseed, and thus potentially affect yield. Therefore, at this stage, we need to pay more attention to taking measures to deal with this cold wave.

For wheat, it is recommended to spray red, indole, brassinolide, dahlia verticillium activation protein and other plant growth regulators, combined with New American Star water-soluble organic fertilizer. These plant growth regulators can help adjust the growth rhythm of wheat and improve its cold resistance. Water-soluble organic fertilizers provide essential nutrients for wheat, enhance wheat physique, and reduce the damage of low temperature rain and snow to wheat.

For rapeseed, before or after the arrival of low temperature rain and snow, it is recommended to spray rapeseed with plant growth regulators such as dihydrochlorin iron and brassinolide in time, and use New American Star water-soluble organic fertilizers at the same time. Plant growth regulators can enhance its resistance to cold during the growth of rapeseed, allowing rapeseed to better adapt to the cold wave environment. Water-soluble organic fertilizers supplement nutrients for rapeseed and help its growth and development. The two are used together to help rapeseed resist low temperature frost damage. In addition to using growth regulators and water-soluble organic fertilizers to supplement nutrients, strengthening field drainage management is also a link that cannot be ignored. In a low temperature environment, the ground temperature will become lower, which will lead to poor soil permeability, affecting the growth and respiration of wheat and rapeseed roots, and in severe cases may cause root rot. Clean and dredge field ditches in time to ensure smooth drainage. Doing so can reduce soil moisture, increase ground temperature, create a good growth environment for the roots of wheat and rapeseed, and promote the overall healthy growth of the plants. The first round of cold waves in the Year of the Snake brought considerable challenges to wheat and rapeseed in Hubei, but by following scientific methods for field management and actively taking cold and frost prevention measures, the wheat and rapeseed babies will surely pass this "cold resistance test" and thrive in the new year. Let us cheer for these little lives in the fields and hope that they will still be full of vitality after the cold wave!
