In the 1-5 leaf stage, early application of manure can be divided into two. For the first time, when the first true leaf is not unfolded (6-8 kg of urea per acre without seed fertilizer), it can promote the rapid growth of 3-4 leaves. The second time is to apply the split fertilizer. The field of the base fertilizer and the seedlings may not be applied, so as to avoid the occurrence of high-node tillers and lengths. If phosphate fertilizer and potassium fertilizer are not applied in the base fertilizer, 20-25 kg of superphosphate and 2.5-5 kg ​​of potassium chloride are applied per mu. The 5-6 leaf stage is divided into the panicle shaking period. For the application of insufficient base fertilizer or base fertilizer, 1500-2000 kg of farmer's fertilizer per mu is applied, the purpose of which is to increase temperature, moisturize and freeze, to make up for the shortage of fertilizer in the early stage. It is generally not recommended to apply quick-acting nitrogen fertilizers, so as to avoid the growth of wheat seedlings after application, the increase of inefficient tillers, and the stalks are slender and soft. The 7-9 leaf stage is the spike-up period. After 7 leaves, 3-4 kg of urea can be applied per acre to achieve the purpose of maintaining the grain. The 9-11 leaf stage is the period of weight gain. At the beginning of the ear and the heading, combined with the prevention and control of pests and diseases, 100 grams of potassium dihydrogen phosphate per acre (0.5-1 kg of available urea in the field of lack of fertilizer or long potential difference), 50-60 kg of water for external application .
