Spring is here, but in the face of early spring, it is in arid drought, and the rainfall in the area is small. Then, how does wheat prevent drought in early spring?
Repression of early spring repression can make the topsoil of the soil loosened by freezing and thawing in winter, so that the soil and the roots are closely connected, which is beneficial to the roots to absorb water, reduce water evaporation, and help prevent wheat from freezing in early spring.
In the case of soil freezing and freezing, the depth of freezing is 2 cm, and the lower layer of the soil is still iced, the ground surface is formed into a layer of dry soil, which can cut off the operation of the capillary water, which is conducive to maintaining soil moisture and has Multiple effects such as warming and killing grass.
Watering for wheat fields with irrigated conditions, timely watering is an effective measure to fundamentally relieve the drought. However, watering must be based on seedlings, late spring wheat field to promote the spring, not suitable for watering in early spring, so as not to reduce the ground temperature to affect growth; strong seedlings in the wheat field to promote control in the spring, soil fertility is poor or the general plot can get up Watering in the period, soil fertility is better, and the relatively large population of wheat fields does not advocate pouring water, but for wheat fields with unguaranteed water source, water can be properly watered early; Wangchang wheat field is dominated by spring, and soil fertility is poor. The plot can be watered during the rise.
