1, timely adjust the variety layout. At present, the suitable sowing date for semi-winter wheat varieties in our province has been missed, and the unplanted plots should be considered to adjust the layout of varieties, plant spring varieties suitable for late sowing in order to give full play to their short vernalization time, stage development. The process is fast, easy to form the advantages of large ear weight. For those farmers who have prepared half-wintering species, they should be replaced. Late varieties such as Wanmai 44, Yumai 18, Wanmai 33 and Zhengmai 9023 can be selected.
2, appropriately increase the amount of sowing. In order to make up for the reduction in the number of tillers per plant in late planting and the reduction in the number of acres per panicle, the sowing amount must be appropriately increased to ensure the appropriate number of basic seedlings and the number of panicles. In the high-yielding fields planted in early November, the sowing rate per mu is 10-12.5 kg; the fertility of the middle and low-yielding fields is poor, and the mu-planting rate can be increased to 12.5-15 kg.
3, germination shallow sowing. If the sowing date is too late, germination can be sown to accelerate the use of the accumulated temperature in the early stage to reach the goal of late sowing and early emergence. The germinated seeds, under the same conditions, generally emerged 2-3 days earlier than the sowing seeds. And the later the sowing date, the more obvious the effect of early emergence. In order to facilitate sowing, germination should not be too long, as long as the "whitening" can be.
4, to promote the no-tillage drill. Because of the seasonal urgency, for some rice paddies or late-to-retire plots, in order to compete early in the evening, the land could not be ploughed and sowed directly with a no-tillage seeder.
5, pay attention to prevent prosperous growth. Due to the continuous rain in early October, the soil moisture is sufficient. This year, the sowing period of wheat in Huaibei area is basically within the appropriate period, and the field emergence is better. In addition, the recent high temperature, wheat seedlings grow faster, years ago prone to prosperous growth. In the event of abnormal weather, it is prone to frost damage, so be sure to pay attention in the field management in the future. In particular, the plots with large sowing, premature sowing, and sufficient supply of fertilizer and water should be prevented from prospering in time, and measures such as roller compaction, deep cultivator, control of fertilizer and water, and rational use of plant growth regulators are generally adopted.
