One is to clear the gutters and prevent waterlogging. Clearing and ditching of frozen wheat fields should be done in time to conserve the root system, enhance its ability to absorb nutrients, ensure the recovery of leaves, the occurrence of new tillers, and the nutrients needed to form spikes.
The second is timely fertilizer application to promote the rapid growth of wheat tillers. The main stem and the wheat field that had been frozen in Oita were topdressed twice. After thawing in the field for the first time, 10 kg of urea is applied per acre and the ditch is applied; the phosphorus-depleted land can be mixed with urea and diammonium phosphate. The second time in the jointing stage of wheat, combined with water-saving fertilizer application, 10 kg urea per acre. Generally frozen wheat fields, only the leaves freeze, there is no dead phenomenon, early spring should be scratching early, increase the temperature, promote the green turn seedlings, in the beginning of the top dressing watering, increase tiller rate.
The third is to do monitoring and prevention of sheath blight and midgeworms, strengthen forecasting and minimize loss of pests and diseases.
The fourth is to strengthen the management of fertilizer and water in the middle and later stages to prevent premature aging. The frozen wheat plant body has more nutrient consumption and is prone to premature aging in the later period. Based on the growth and development status of the first time in the spring, potassium dihydrogen phosphate and “2116†can be sprayed during jointing or flagging period. Or "Fujim Potassium" and other foliar fertilizers to enhance the photosynthesis of wheat, resist dry hot wind, promote large grains and large grains.
