According to statistics on the 5th of December, the large-scale group of wheat in Hai'an County is basically normal, and the individual quality is better than last year and perennial, but there are still two outstanding problems. 1. The unbalanced nature of the seedlings is more prominent than the few field plots. Because of the seed germination potential difference, coupled with poor seed quality and drought after sowing, the seedlings are less and slower, and the field seedlings are currently poor. For example, the Dagong and Baidian seedling monitoring sites showed that on December 5, the average number of basic wheat seedlings per mu was only 96,500, and the total number of seedlings per mu was 122,300, leaf age was 3.12, and 0.29 were planted per plant. Miao Shao and Miao Weak are the main characteristics of this section of the plot. 2. Some plot managements are not in place, and freezing hazards, waterlogging hazards, and grassland hazards are not supported in a timely manner by part of the trenches. The compliance rate is low, the internal and external trenches are not matched, and they are not smooth, and the conditions for drought resistance and poor waterlogging are poor. Rapid flooding and increased rainfall can easily cause waterlogging. Due to the relatively poor seedling quality of drought-fed wheat, such as the sudden cold wave, it may be threatened by serious frost damage. Autumn weeds occur relatively less due to drought, and the fall area in addition to the corresponding decrease, the possibility of increasing weeds in winter and spring. In view of the current characteristics and problems of wheat seedlings, it is necessary to strengthen the classification guidance and strive to promote the transformation and upgrading of seedlings. Supplementing fertilizer to promote strong wheat seedlings or base fertilizer is not enough and late seedlings weak wheat fields, to make early use of Miaofei or tiller fertilizer to ensure that the base Miaofei pure nitrogen dosage of 9 to 10 kg, accounting for the total nitrogen Approximately 60% of the volume will promote leaves and tillers, which will lay the foundation for strong seedlings, ear and spikes. For the appropriate sowing, the basic seedlings are moderate, the basic fertilizers are good, the foundations are good, the growth is normal, and the group I and II seedlings in the group are more full. There is no need to apply topdressing fertilizer and do not need to apply wax fertilizer or green manure. For late-seeding weak seedlings and small wheat fields with basic seedlings, it is necessary to combine “work promotion and fertilizer promotion†to promote transformation and upgrade of the seedlings. In order to support the use of sunny trenches, the “Three Ditches†inside and outside the valley should be opened early in the day, and the horizontal trenches should be opened and the trench heads should be connected to ensure that the trench system is unblocked and the drainage capacity of the rafts can be improved. Dry, to prevent severe waterlogging in winter and spring, even in the rainy weather, to avoid alternating freeze-thaw, increase the damage and frost damage. For Banzhao field and interplanted wheat fields, coverage can be enhanced by adding fertilizer or mud cover, and the mulch insulation and frost protection can be applied. Warming up and controlling the use of the “Diao Miao Zhuang†seed dressing control, the emergence of prosperous or prosperous wheat fields, to warm up before the overwintering to use warming control agent, in order to achieve stimulating, promoting root , dwarf, antifreeze effect. Can use "dwarf Miao Zhuang" 2 to 3 bags of water evenly spray per acre, control the length of plant base internodes and enhance lodging resistance and cold resistance.
