Do a good job of repression, protection, warming, and early warning
The crackdown of wheat fields in the early spring is an important agronomic measure to control water use and increase water use efficiency. Therefore, it is necessary to suppress the growing wheat fields several times in order to suppress the growth of the aboveground areas and control the growth of strong growth and lodging. For wheat fields that are extensively planted in the autumn and cultivated in many places, the wheat fields should be promptly repressed in the early spring after the soil is thawed, in order to sink the soil, bridge the cracks, reduce water evaporation, and prevent cold air from invading the frozen wheat seedlings near the tillering festival. For non-irrigated dryland wheat fields, repression of the wheat field after soil defrosting in the early spring can promote the water in the lower layer of the soil to move upwards, and it can promote hoeing, preserve maggots, and resist drought. Compression should be carried out in combination with ploughing. Generally, crumple should be pressed afterwards in order to achieve the effect of increasing the temperature of Panasonic. Scratching is an effective measure to promote warming and early warning. Although the precipitation in autumn and winter last year was large, the current situation of wheat field is generally better, but after the spring, with the increase of temperature, the soil evaporation increases, and “spring rain is expensive as oilâ€, and the precipitation has uncertain factors. Therefore, in order to prevent the drought in spring, it is critical to do everything possible to keep underground sampans. All localities must organize and mobilize the peasant masses as soon as possible so that all types of wheat fields can be plucked in the early spring when the surface layer is frozen and 2 centimeters cold (in the top of the flood season) to maintain soil moisture, increase surface temperature, eliminate overwintering weeds, and win over the management of wheat fields in the later period. initiative. Especially for wheat fields where the population is small and individuals are weak, scratching should be used as the primary measure for management of early spring wheat. In addition, when watering or raining in the spring, we must also plan to draw in due course. When ploughing, we must do a good job of slicing, smoothing, leveling, and penetrating. Do not leave scum, squeezing wheat seedlings, or weeds, so as to improve effect.
