Land preparation and breeding methods
1. The site selection site has selected Xiangyang ventilation, deep soil, loose fertility, and good drainage. The former can be used as corn, wheat, beans, sweet potatoes, etc., as planting sites. After harvesting the former crops, it is 30-40 cm deep and ploughed twice. It requires intensive cultivation, combining ploughing with 667 m2 of applied fertilizer or 2500-4000 kg of compost for basal fertility. In the rain-rich areas, the width of 100 cm and the height of 20 cm are used for drainage, and in dry areas, it is 130-230 cm. Open a drainage ditch around. 2. Propagation methods White pheasants are mainly produced by splitting and rooting in production, and they can also be propagated by seeds. Because of the long growth cycle, production is rarely used. (1) Dividing into roots During the harvest, the root of the white peony root is cut off from the part where the bud is to be planted, and the shape of the bud with a large, non-hollow head is selected, and the shape is naturally grown according to the size and the number of buds. Cut into several pieces, each with 2-4 buds, reserved for species use. In general, the axillary buds obtained per 667 square meters of alfalfa can be planted in 2000-2666 square meters (3-4 mu). White storks are best planted with the digging. If they cannot be planted in time, they should be temporarily stored by selecting a cool, ventilated room and laying a layer of 3-4 cm thick moist sand on the ground to pile up the buds. , Thick 10-13 cm, covered with 7-10 cm wet sand, surrounded by bricks around, after half a month after the cover soil is dry, appropriate sprinkler insulation. If rot is found, it should be turned in a timely manner, pick up the rotten hoe, and then re-stack to prevent the spread. Can also be in the outdoor, choose a cool, dry, high ground, well-drained shade, stacking l0 cm thick, cover 7-10 cm moist sandy soil, cover the corn on the top, and then cover the sand 7-l0 cm. During storage, the covered sand should be often sprinkled with water to keep it moist and prevent shoots from drying out. Pay attention to drainage when it rains. If it is too wet, remove the corn stems, ventilate and dry them to avoid mildew. (2) Seed-reproducing single-valves of white peony are more solid, and the seeds are mature in mid-August. When the micro-cracking occurs, the seeds are picked in time, with the harvesting, or mixed with wet sand and stored until the middle and late September. The seeds should not be dried. . In the whole area of ​​the nursery, a 50-cm 30-cm gap was opened and the depth of the hole was 3 cm. Seeds were sown at 3 to 5 pellets per hole. The soil was compacted and covered with a layer of 7-10 cm soil. The seeding rate is 3.5-4 kg per 667 square meters. The upper cover soil was removed in early April of the second year, and the soil can be excavated in about half a month. After that, the cultivating and weeding topdressing is strengthened. After 2-3 years of seedling growth, planting can be carried out, leaving 1-2 seedlings per hole. This method has a long reproductive cycle and is rarely used in production. It is only used for breeding. China Agricultural Network Editor
