Embodiment Construction
[0009] The method for propagating the sweet potato tuber component will be further described below.
[0010] Propagation Method of Sweet Potato Tubers The following steps are used to achieve: 1. Preparation of training base: dry land with a water content of 15-25%, intensive cultivation and meticulous cultivation, the soil is mixed with lime to sterilize, the dosage is 50 kg / mu, and the soil is mixed with sulfur and phosphorus particles to kill ground insects, 1.5 kg / In winter and spring, greenhouses should be set up to keep the soil temperature at 18°C~35°C; 2. Bury the sweet potato strips into the medium soil as a whole, with a depth of 3~5 cm, and compact the surface soil after embedding; 3. It sprays water to keep the culture medium soil moist, with a water content of 20-35%; 4. Dig out the sweet potatoes carefully after 4-6 days of burying, and carefully spray the whole body of the sweet potato soil with clean water to expose the buds all over the body of the sweet po...

Abstract
The invention relates to a method for quantitatively reproducing sweet potatoes by the aid of tubers, and belongs to the field of agricultural technologies.The method aims to solve problems in the aspects of reproduction time and quantities of newly discovered sweet potatoes.The method mainly includes steps of firstly, preparing cultivation foundations, to be more specific, mixing lime with dry lands with the water contents of 15-25% to sterilize the dry lands, mixing 1.5 kilograms of quinalphos particles with each mu of the dry lands to kill land insects, and setting greenhouses in winters and springs to keep the soil temperature of 18-35 DEG C unchanged; secondly, integrally burying strip-shaped sweet potatoes into cultivation foundation soil at the buried depths of 3-5 centimeters; thirdly, periodically spraying water to keep the water contents of 20-35% unchanged; fourthly, digging out sweet potatoes after 4-6 days, spraying clear water to clean soil on the whole bodies of the sweet potatoes and exposing buds at various positions of the whole bodies of the sweet potatoes; fifthly, slitting the sweet potatoes by the aid of knives according to spaces between buds so as to allow each bud to be provided with the corresponding sweet potato tuber; sixthly, soaking the various slit sweet potato tubers in 400 ppm KIBA or IBA or NAA auxin solution; seventhly, burying and planting the various tubers according to the spacing of 20-30 centimeters/plant.
