Problems solved by technology
Late cropping of winter wheat will result in insufficient wheat accumulated temperature, weak seedlings, few tillers, shallow roots, and few secondary roots. Strong seedlings cannot be formed before winter, and they are vulnerable to freezing damage and drought damage, which is not conducive to safe overwintering
Spring planting of winter wheat without winter covering, as the sowing time delays, the rate of ear formation decreases, and finally leads to ineffective tillers and no earing. It can only be used as green fodder. If it is not planted, a season of crops will be delayed.
Spring wheat is suitable for mid-high latitude cold winter areas, winter wheat cannot survive the winter here, otherwise it will freeze to death, and the yield and quality of spring sowing and summer harvest are low

Embodiment Construction
[0006] A method for planting winter wheat in spring, the method comprising the following steps: a. selecting winter wheat varieties with large spikes, thick stems, resistance to lodging, and resistance to diseases and insect pests according to the sowing conditions such as local land and climate; b. One month before topping, soak the selected wheat seeds in water for 24-30 hours; c, control the temperature of the soaked wheat seeds and store them in a 0-degree environment to keep them moisturized, so that the young sprouts are in a dormant state for overwintering, and the temperature control can Artificial intelligence control is adopted, the temperature fluctuation does not exceed 1 degree, and the moisture retention is just to pack the soaked seeds into bags, which can be sprayed with water regularly; d. After the soaking treatment, the wheat seeds that have survived the winter can be sown successively from the top after the spring , the latest sowing time should not be later...

The invention discloses a spring sowing method for winter wheat. The method comprises the steps of wheat seed selection, wheat seed soaking, moisturizing, storage and overwintering of the soaked wheatseeds, slush sowing of the overwintered wheat seeds in spring, field management and insect disease prevention until the winter wheat is ripe. The spring sowing method for the winter wheat has the characteristics that the winter wheat is sown in spring, the yield is high, management is facilitated, and influences by external conditions are small.
Description
technical field [0001] The invention belongs to the technical field of crop cultivation, and in particular relates to a spring planting method of winter wheat. Background technique [0002] Wheat is divided into winter wheat and spring wheat according to the sowing season. Winter wheat is suitable for middle and low latitude regions. For example, winter wheat is south of the Great Wall of China, and spring wheat is north of the Northeast Plain. Winter wheat is harvested in the second year of autumn sowing, and its yield is high. The suitable sowing time is restricted by many factors. Seedlings are the foundation of high yield. The so-called timely means that the temperature is 14-16°C, the accumulated temperature before winter is 570-650°C, and the suitable moisture content is that the ground moisture content of 0-20cm reaches 70-80%, and less than 70% is unsuitable moisture content. Late cropping of winter wheat will result in insufficient wheat accumulated temperature, w...
