Method for quantitatively reproducing sweet potatoes by aid of tubers

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.

Description

technical field [0001] The invention relates to the technical field of tuber propagation, in particular to a tuber component propagation and growth technology, which belongs to the field of agricultural technology. Background technique [0002] Sweet potato (English: sweetpotato) formerly known as sweet potato (scientific name: Ipomoeabatatas (L.) Lam.), also known as sweet potato, sweet potato, sweet potato, rice, sweet potato, sweet potato (northern), sweet potato, thread sweet potato, sweet potato, golden potato, Sweet potato, red potato, pillow potato, sweet potato, white taro, fennel sweet potato, etc. Sweet potato belongs to Tubular Flowers, Convolvulaceae annual herbaceous plant, more than 2 meters long, lying on the ground and slanting upwards, the leaves are usually wide ovate, 4-13 cm long, 3-13 cm wide, the corolla is pink, white, pale Purple or purple, bell-shaped or funnel-shaped, 3-4 cm long, capsule ovate or oblate, with pseudo-septum, divided into 4 chambers...

AI Technical Summary

Problems solved by technology

[0003] Sweet potatoes belong to asexual reproduction species, but sweet potatoes can also flower, and new individuals can be obtained through hybridization, but such sexual reproduction takes too long to meet the requirements of mass production; people can use tuber propagation and vine stem branch propagation Propagate new individuals, among which the vine short stem propagation method is the most commonly used, and the tuber propagation method is less used, because the tuber propagation wastes too much sweet potato

But if people find a kind of sweet potato with better quality and taste, but only sweet potato body and no vines for the time being, they can only use tubers for propagation. General tuber propagation cannot divide a sweet potato into too many pieces. soon rot
