Agricultural concerns and recommendations
1. Different droughts must be scientifically watered. For heavy drought, rotary arable land, weak seedling fields, irrigation conditions should be hurry up, and the irrigation should be carried out in the afternoon. The amount of irrigation can be infiltrated into the field, without water accumulation, avoid flooding; for sandy land, due to recent The wind is windy and the wind is large. The surface soil is easy to be blown up, so that the roots of the wheat are exposed. Special attention should be paid to the protection of the frozen and the areas where conditions are available. Straw covering and other measures can also be taken.
2. Different seedlings should be classified and managed. Due to the high temperature in the previous period, some plots of wheat seedlings are prosperous and vulnerable to freezing damage. They can be controlled by repression, deep roots and other measures. The wheat fields with rotary soil and no irrigation conditions can be repressed to promote deep rooting; Weak seedling plots should be topdressed and weakened.
3. Facility agriculture, it is necessary to keep warm and freeze. As the temperature continues to decrease, all localities should pay attention to the heat preservation and antifreeze work of the greenhouse vegetables. The ventilation and light transmission should be carried out on a sunny afternoon, and the curtain time should be controlled according to the weather changes.
