1, timely castration The last time a year's cuttings should be arranged between 1 and 1.5 months before the freezing, and still more than one month after the harvest is conducive to the accumulation of nutrients and safe wintering of the alfalfa and re-emergence of pasture in the following year. 2, stay appropriate The remaining height of the harvest at the time of the last harvest of the year directly affects the growth rate of the regenerated grass. Stay high, regeneration speed is fast, otherwise slow. The remaining height of the last pass is proportional to the wintering rate. However, high stubble retention will affect the grass yield of the former valerian. Therefore, the height of the stubble that is harvested before winter must be between 5-6 cm. 3, reasonable dressing In the winter and early spring, the top dressing should be combined with irrigation. Phosphorus, potash or barium fertilizers are generally used for the earthworms, and nitrogen fertilizer is suitable for the seedlings. The ratio of nitrogen, phosphorus and potassium fertilizers is generally 4-5:1:2. 4, pouring frozen water Pre-frozen once poured frozen water will help increase the winter rate. In the same early spring, Qing Shui should also be poured back. Each irrigation to the soil saturation and suitable water capacity in the field. 5, shop cover or mechanical casing Small-scale growers cover 10 cm thick straw and other coverings on loquat planting plots, which can effectively increase the wintering rate of alfalfa; large-area growers can use machinery to cover the soil before freezing, and adjust the speed of the traction machinery. Control the depth of soil cover. The mechanical casing should be carried out within 10 days before the freezing, and the depth of earth covering should be about 5 cm. If the depth is too deep, it will affect the return of green pasture in the coming year.
