Agricultural production advice
Before the 13th, Shanxi Province was mainly cloudy and cloudy, which was beneficial to the wheat area. However, the cooling weather that may occur on March 14 has a certain adverse impact on the smooth progress of irrigation in the wheat area. The wheat area should be scientifically organized according to the temperature conditions, and the amount of irrigation on the 13th should be reduced as appropriate to ensure that the infiltration can be completed on the same day, avoiding the clear water overnight, and can play a role in preventing frost.
Suitable irrigation areas can be used to nurse the winter wheat to the green water, and the wheat fields with good moisture and seedlings can be appropriately delayed. Some late wheat and weak wheat fields can be topdressed while irrigating. The roots will be increased to achieve the transformation and upgrading of the seedlings; some areas with poor irrigation conditions need to be managed in a row to improve the temperature and ensure the evaporation of soil moisture.
Areas more suitable for irrigation should pay close attention to weather changes, scientific irrigation according to temperature conditions, ensure that there is no clear water overnight, prevent winter wheat from being frozen, and manage the field classification of winter wheat during the greening period.
At present, some frozen wheat soils still exist in some wheat fields. It is not advisable to prematurely water the green water to avoid frostbiteing the wheat seedlings. At the same time, strengthen the field management work, actively carry out the plan and protect the winter wheat, and promote the timely return of winter wheat.
