Winter irrigation in cotton fields ensures that the cotton in the next year will reach the full seedling and the seedlings. The farmer said it well, "the cotton field is covered by winter irrigation, and the cotton peach is racing." If winter irrigation is not carried out, the lack of mantle will affect the normal growth of seedlings and seedlings when cotton is planted in the following year. It has been proved by experiments that winter irrigation in cotton fields increases yield by more than 20% compared with late spring irrigation. because:
1 Winter irrigation can make cotton fields accumulate sufficient water. After winter irrigation, as long as the work is carried out, the cotton germination, emergence and seedling water requirements can be met under normal circumstances.
2 Farm Road: “After freezing and disappearing, the ground is grayed outâ€, “The dry plough is dry, the wet plough is wet, and if you don’t want to smash it, unless it is irrigated in winterâ€. These farms have said that the winter irrigation can eliminate the cotton field, and through the action of freezing and dispelling, the soil will be loose, which is conducive to cotton emergence and growth.
3 Winter irrigation can also promote the conversion of organic fertilizers in the soil, which is conducive to the absorption and utilization of fertilizer by cotton.
4 Winter irrigation can also kill the eggs in the lower part of the cotton field to prevent or reduce the damage of the insects to cotton. The winter irrigation time should be based on the principle that it should be sooner rather than later. Generally, it should be carried out when the surface begins to freeze or freeze. The amount of winter irrigation can be appropriately larger, generally not less than 80 to 100 cubic meters per mu. Generally from mid-December to early January. Winter irrigation should pay attention to irrigation and irrigation, and do a good job.
