1, drainage and flood control
We furrow wheat fields and wheat fields, which is the last link in the process of wheat sowing and the most important thing of wheat sowing. We ditch in the wheat field mainly for drainage and flood control. After planting the wheat field, ditch around and in the middle of the wheat field. In order to avoid water accumulation in the wheat field when it rains, it is easy to splash the wheat seedlings yellow and affect their growth, and even splash them to death in serious cases.
2. Spraying pesticides is convenient for walking
The second function of furrowing in wheat field is to facilitate walking when applying pesticide to wheat. You should know that wheat should be sprayed with pesticides at least two or three times according to its growth and diseases and the growth of weeds in its life. At present, it is not realistic to use unmanned aerial vehicles to spray drugs on slopes of different sizes in Qiu Ling.
The role of hengtougou
Hengtou ditch refers to a horizontal drainage ditch about three or four meters in the ridge of Hengtou field according to the topography of wheat fields. This communication is often connected with the middle compartment, so that the accumulated water at the horizontal end of the wheat field can be diverted by the middle compartment.
However, the side ditch between the horizontal ditch and the ridge with the horizontal head on the ground should be closed. This is to avoid the water from the lateral ditch of the horizontal head flowing back to the middle compartment ditch, which will cause the drainage backlog in the compartment ditch.
