In winter, many of the kudzu have been overwintering because they did not meet the harvesting standards. If they do not take corresponding measures, they are vulnerable to low temperature hazards, ranging from plant frostbite to growth and yield in the coming year. The following four kinds of easy-to-follow measures for the wintering of Pueraria are described below.
First, soil fertilization. In the beginning of winter season, 15 cm of the ringwood ditch near the trunk of the tuber bud was applied with 3 kg to 5 kg of high-quality farmyard manure and 0.25 kg of phosphorus fertilizer, and the antifreeze water was poured. Use residual soil or clear soil to cover the base of more than 20 cm, can better reduce, reduce or avoid the hazards of low temperature.
Second, debris coverage. Use cold straw, weeds or sawdust to cover the base of more than 20 centimeters before the cold begins, and then use firewood, bamboo or stones to suppress it. Let it wear a thick layer of "cotton clothing", which can not only stabilize the temperature, but also resist the invasion of low temperature;
Third, take a low arch shed. With a mulch in the garden, take a low arch shed, about 30 centimeters high. The membrane is compacted with mud and windproof. If it is overwintering, it can be cut into 80-cm squares with scrap film and then laid on the base and covered with 3 to 5 cm of fine soil or withered grass.
Fourth, indoor and outdoor implants. A layer of 15 to 20 cm thick wet sand is laid in the interior of the building. A row of fennel is placed on top of the sand, a little water is sprayed, and a layer of sand is covered. According to this method, the uppermost layer of sand can be thickened to 30 cm. If the outer layer of river sand is dry, appropriate amount of fresh water may be sprayed. Outdoor fake planting selection slightly higher terrain, leeward sun dug a fake planting points, the number of specifications to determine the number; then the Pueraria upright in the hole, the base up, a layer of fine soil seedlings, stepping real. The base is slightly more than 3 to 5 centimeters above the ground and covered with thin film or withered grass.
