What is the significance of fright in agricultural production?
After the dormant festival comes, the temperature will rise by 3~4 degrees. In the south, the grass grows and the warbler flies, and the willow grows and the duck is warmed in spring. In the north, the snow and ice melt, people take off their thick winter clothes and are busy with their livelihood for a year. Wheat and broad beans grow vigorously and spring is full of vitality.
In the twenty-four solar terms, awakening is a phenomenon that reflects the germination and growth of natural creatures under the influence of rhythm changes, and it is also a reflection of ancient farming culture on natural festivals. Farming production is closely related to the rhythm of nature, and the shocking solar terms are of great significance in farming. Since ancient times, our people have attached great importance to this solar term and regarded it as a spring ploughing festival.
After the shock, agricultural production should prevent spring drought for the first time. It can be said that "Jingzhe" is a solar term with the fastest annual warming in China. During this period, the sunshine also increased obviously, but the rainfall was limited. In order to ensure the normal greening of wheat in the north, normal jointing of wheat in the south and normal flowering of rape, crops can be planted in spring to reduce water evaporation; Arid areas can be irrigated with water to prevent spring drought from affecting crop yield.
Secondly, the crops should be fertilized reasonably during the period of fright. At this time, the crops begin to grow again, which requires higher water and fertilizer, and requires timely topdressing. Peach, pear, apple and other fruit trees are about to bloom, so it is necessary to apply fertilizer reasonably before flowering, which is beneficial to protect flowers and fruits. Don't blindly broadcast early when the thorn comes. For areas with unstable weather and large temperature fluctuations, do not blindly broadcast in advance. When the temperature is stable at about 12 degrees, plant crops such as rice or corn.
