Harvesting and planting is just the time

Frost-fall solar terms are coming. Frost-fall solar terms mean that the weather is getting colder and frost starts. This stage is cold in the morning and evening. Due to the long delay of the rain, the harvest and drying of mature crops in Rehmannia glutinosa were delayed, and the rice germination and lodging at different levels in the field were delayed, which also delayed the northern winter. Seasonal seeding of sex wheat.

First of all, to speed up the sowing and tail cleaning of northern winter wheat, it is necessary to adopt flexible sowing methods. Because the later sowing is not easy to grow strong and hardy before winter, the later the heading is delayed, the heavier the mildew will be.

To choose the right variety, choose varieties that are resistant to late sowing, such as Yannong 19, Quanmai 725, Yannong 999, and Huai Mai 35, and Huai Mai 30 and Xin Mai 21 can be selected later.

Because the fields in the north are heavy stubble, and a large number of straws are returned to the field, soil-borne diseases are relatively large. Be sure to use seed coatings to mix seeds. This is the most important. Coincidentally, or the big brands of domestic regular manufacturers can be used.

Late sowing of wheat must appropriately increase the amount of sowing. Due to the impact of early rain, the germination rate of wheat this year is not high, and at this time it is really necessary to appropriately increase the amount of sowing. Regardless of whether it is planted or spread, it must be increased to about 30 pounds. This year, the emergence rate can only reach about 70%, that is, 30 pounds of wheat seeds can also produce about 200,000 basic seedlings.

The straw returned to the field, especially the corn returned to the field, requires nitrogen fertilizer to supplement trace elements, and the process of rotten straw consumes a certain amount of nitrogen fertilizer. In addition, northern wheat depends on the suppression of crickets. If the crickets are wet, do not suppress them to avoid affecting the germination rate.
