From late December of last year to early January of this year, when the author investigated in multiple places, he saw that some wheat seedlings began to bleed yellow or the entire leaf, and some village groups made about 20% of the yellow area of ​​wheat seedlings. There is still dead, so that the growth and development of wheat is inhibited. The reasons are as follows: First, some areas continue to be dry at the time of sowing, and some farmers do not use the bottom (basic) fertilizer in a timely manner or apply less fertilizer. After the wheat seedlings reach the end, they encounter persistent rain, and they do not immediately follow up on fertilizing materials, making wheat seedlings unable to absorb them. Nutrition and fertilizers become yellow and grow weak; Second, many farmers lack labor force to use herbicides to control weeds, because the choice of herbicide is not on the road or the application of excessive concentrations, or repeated spraying, so that wheat seedlings suffered phytotoxicity; The third is the damage caused by Maiyuan spiders, which often causes blockage or damage of the wheat seedlings. The yellow leaves are reddish. In summary, the yellowing of wheat seedlings is mainly caused by the shortage of fertilizer and water, pesticide pests, and poor drainage in the field. To this end, the following measures should be taken to improve the ecological environment in the field, cultivate strong seedlings, and lay a good foundation for high yields. For fertilization, fast-acting nitrogen fertilizers need to be quickly followed. In order to promote the transformation of wheat seedlings as soon as possible, immediately apply topdressing nitrogen fertilizer, apply 15 to 20 pounds of urea per acre or ammonium bicarbonate 40 to 60 pounds, or chase water manure 1000 to 1500 pounds. At the same time, the combination of drug and drug use alleviates injury. One can use plant growth accelerant 0.01% of Tianfeng or Paulownia (brassica lactone), two can use 0.05% of the "920", three available "802" 2000 times liquid to distinguish the actual situation of spraying 1 or 2 times , Four available active liquid fertilizer Huimanfeng or Zhuang Fuxing 2000 times spraying, can gradually restore the normal growth of wheat.
