Suggestion: Due to the strong cold air, the winds and winds and precipitation are obvious. The early rice has been planted to strengthen the management of the paddy field. The planting and breeding methods are used to ensure the regulation of temperature and humidity. The method of moistening and cultivating is used to cover the membrane and deep water in the ditch. On the upper surface, the early rice seeds that have been germinated should be spread out, and the soil should be planted after the weather is improved. The scaffolding crops and poultry houses should pay attention to strengthening and preventing the wind from falling into the shed. At the same time, the temperature and humidity should be adjusted; the rapeseed, vegetables and other field crops should be Pay attention to cleaning the three ditch to facilitate drainage. It is predicted that the weather will turn better in the late second half of the year, and the temperature will gradually rise. It is beneficial to spring sowing springs. It is advisable to use heat preservation methods in different places and carry out early rice breeding in batches. At the time of breeding, attention should also be paid to the selection of variety maturity and species to mitigate disaster risks. The rapeseed field can be topdressed according to the seedling condition and the prevention and control of sclerotinia disease.
