Seedling growing method for trichosanthes kirilowii maxim tuberous roots

Abstract

The invention relates to seeding growing of trichosanthes kirilowii maxim, and discloses a seedling growing method for trichosanthes kirilowii maxim tuberous roots. The method comprises the steps that(1) the trichosanthes kirilowii maxim tuberous roots are taken and cut into chunks, then the trichosanthes kirilowii maxim tuberous root chunks are soaked in a potassium permanganate aqueous solution, ventilated, aired and dipped in rooting powder, and pretreated trichosanthes kirilowii maxim tuberous roots are obtained; (2) fermented and decomposed cottonseed hulls and river sand are mixed and spread out, and a seedling growing substrate is obtained; (3) disinfectant fluid is sprayed to the seedling growing substrate, the seedling growing substrate and the disinfectant fluid are uniformly mixed, subjected to standing and watered, and a pretreated seedling bed is obtained; (4) the pretreated trichosanthes kirilowii maxim tuberous roots are transversely placed on the pretreated seedling bed and covered with fine sand, and new buds grow. According to the seedling growing method, trichosanthes kirilowii maxim seedlings with consistent seedling emerging, good developed root systems and strong buds are obtained, in the seedling growing process, the phenomenon of rotted roots of the trichosanthes kirilowii maxim seedlings is reduced, in the later transplanting process, the seedlings canbe conveniently taken, after transplanting, the buds cannot be easily damaged by diseases and pests and can quickly adapt to the transplanting environment, and in addition, the seedling growing method is simple, high in operability and quite beneficial for planting expansion of trichosanthes kirilowii maxim.

Description

technical field [0001] The invention relates to seedling cultivation of Trichosanthes chinensis, in particular to a method for cultivating seedlings of Trichosanthes chinensis root tubers. Background technique [0002] Trichosanthes kirilowii Maxim (scientific name: Trichosanthes kirilowii Maxim) belongs to Cucurbitaceae, Trichosanthes is a perennial climbing herb, up to 10 meters long. The rhizome is thick, cylindrical, and the outer skin is yellow. Stem much branched, glabrous; leaves alternate, nearly round or heart-shaped, dioecious; male flowers several racemes, rarely solitary, corolla lobes obovate, female flowers solitary, ovary ovate, fruit nearly spherical, Orange-red when ripe, flower and fruit period from July to November. Trichosanthes has antipyretic and thirst-quenching, diuretic, antitussive and expectorant effects. Seeds contain fatty flower oil; fruits contain triterpenoid saponins, organic acids, resins, sugars, and pigments; roots contain proteins, sap...

Problems solved by technology

However, when farmers use root tubers to grow seedlings, the length of the tubers and the thickness of the stems are different. The seedling substrate and the tubers that have been born for several years are relatively random, and the emergence of seedlings is often inconsistent, the root system is not well developed, and the buds are not strong. Dip in plant ash, but the concentration of plant ash is not easy to control. If the concentration is too high, it will cause corrosion. More than one day, not only that, but in this case, seedlings tend to cause rotten roots

The shortcomings of the above seedling raising techniques often cause inconvenient cultivation and management in the later stage, easily cause pests and diseases, slow growth and development, and affect flowering and fruiting
