Due to the high proportion of late-casting plots and drought, the current wheat seedlings in some provinces showed small leaf age, less tillering, and increased proportion of the three types of seedlings. The overall seedlings were worse than the previous year, and the drought also affected the emergence of rapeseed. And Qi Miao. All localities should strengthen the classification and guidance, pay close attention to field management, and strive to promote the transformation and upgrading of wheat and rapeseed.
Drought-resistant seedlings and seedlings fill the gap to ensure that the drought-fed wheat field is filled with water before winter, fertilized with water, promotes growth and root development, and prevents dry and dead seedlings. For fields that have not emerged due to drought, they should be irrigated or watered as soon as possible to promote emergence and full seedlings. For small wheat fields that are not well-fed and have insufficient seedlings, they should be germinated to replant or dilute as much as possible. For live rapeseed fields lacking seedlings and ridges, it is necessary to do a good job of replanting seedlings as soon as possible.
Because the seedlings and fertilizers promote the strong seedlings on the wheat fields that are not applied with the base fertilizer or the amount of base fertilizer, it is necessary to apply the seedling fertilizer or the tiller fertilizer as soon as possible to ensure that the base seedling fertilizer applies 9-10 kg of pure nitrogen per acre to promote leafing and tillering. The type of fertilizer is suitable for ternary compound fertilizer and urea, ensuring that the ratio of phosphorus to potassium fertilizer is 5:5, promoting rooting, long sorghum and enhancing the cold resistance of plants, and avoiding the cold resistance of single use of urea. For the first- and second-class wheat fields with suitable sowing, basic seedlings, adequate application of basic fertilizers, normal growth, and relatively large populations, there is no need to apply topdressing or apply fertilization or green fertilizer to inhibit the occurrence of ineffective tillers. After the jointing stage of wheat, the joint fertilizer was applied. For the wheat fields with large amounts of straw returning, it is found that there is a tendency to fall into the yellow-scarred seedlings, and 5-7 kg of urea can be supplemented. The amount of fertilization in the wheat-returning jointing stage can be appropriately reduced. Weak seedlings planted late in late planting and uneven rapeseed fields are required to apply 7.5 kg of urea per acre or “grab the yellow pond to promote balance†to promote the transformation of seedlings. In hilly areas and high-yield fields of rapeseed, special attention should be paid to the application of boron fertilizer.
Warming and weeding control, general grasses, weeds in more than 450 plants per square meter, broad-leaved weeds in more than 90 plants per square meter must be selected to prevent the use of chemicals. Master the daily average temperature of 5 ° C or more on the sunny day to ensure that there is no low temperature frost below 0 ° C within 7 days after the use of the drug to improve the elimination effect, to avoid phytotoxicity. The long-growing wheat, the early-growing and early-growing of rapeseed fields and rice-planting wheat (oil) fields, which have been chemically regulated without the use of chemical dressings in autumn, should be used once in winter before the winter. In order to achieve the purpose of promoting phlegm, rooting, dwarfing, and antifreeze.
