What about the freeze on rice in rapeseed rape?
The anti-freezing of rice and glutinous crops should be combined with flood resistance. The main measures are: timely digging drainage in the three channels (cargo channel, gutter and gutter), and reducing the humidity in the field. In the case of cold-frozen early-growing and early-flowering rapeseed, clear leaves of frozen and frostbite were removed in sunny days to promote branch growth. Make up fertilizer material. Generally, 5-7 kilograms of urea are applied, potassium chloride is 3-4 kilograms, or 0.2% potassium dihydrogen phosphate solution is sprayed, or a compound fertilizer with a nutrient amount is applied. After the snow melts, it is prone to frost at night, and it can be used to spread ash or husks in the field and cover the appropriate amount of straw or livestock manure to protect against freezing. Timely application of pesticides to diseased plots, prevention and control of pests and diseases.
