Technical points: First, use good varieties to make up late. Should be used in semi-winter and semi-winter spring varieties. The second is to improve the quality of soil preparation so as to make up for the night. As early as possible, early sowing. Fine soil preparation, enough for planting; under the premise of athlete's foot, suitable shallow sowing, sowing depth of 3 ~ 4 cm; soaking germination, soaking in warm water of 20 °C ~ 30 °C for 5 hours before sowing, remove and air dry sowing It can also emerge 2 to 3 days earlier. The third is to increase the number of broadcasts appropriately to cover late. Relying on the stem of the main stem is the key to increasing the yield of late buckwheat. Increase the sowing rate should be to ensure that the appropriate number of spikes per acre of the species is achieved, but also to avoid excessive sowing caused the group is too large, the stalk is weak, resulting in lodging production. The fourth is to increase fertilization material to supplement fertilizer late. Late sowing of wheat should increase the amount of fertilizer, balanced fertilization of nitrogen, phosphorus, and potassium, with special emphasis on the application of phosphate fertilizer, can promote the development of wheat roots, promote the growth of tillers, and increase the percentage of tillers and spikes. Appropriate increase in the amount of sowing, relying on the main stem into the ear is the key to increasing yield of late buckwheat. The fifth is scientific management to strengthen the seedlings and create more spikes. In the early spring, the buckwheat is returned to the green period to increase the temperature and promote the early and long-term growth of wheat.ç‹ Grasp the management of fertilizer and water during the period. This technology is mainly applicable to late-seeding wheat fields in various winter wheat regions. Author: Chongming Nong Technology Center
