Asexual propagation method of zingiber striolatum diels

Abstract

The invention provides an asexual propagation method of zingiber striolatum diels. The asexual propagation method specifically comprises the steps: cutting and dividing subterraneous tubers of zingiber striolatum diels growing for 3 years or longer into zingiber striolatum diels tubers in a way of retaining 2-3 buds on each tuber in the first ten days of March to April calculated according to a gregorian calendar, carrying out hole loading on a land parcel with humus soil, and taking plant ash as a fertilizer; covering each plant of zingiber striolatum diels with decomposed cow dung in winterof the same year to provide nutrients for the zingiber striolatum diels, protect the subterraneous tubers from suffering from freeze injury and make the zingiber striolatum diels grow inflorescences in advance in spring of the next year; and growing the zingiber striolatum diels on the same land parcel for 2-3 years to make the subterraneous tubers of the zingiber striolatum diels lump, and then,carrying out harvesting. According to the asexual propagation method, the asexual propagation of the zingiber striolatum diels is performed in the first ten days of March to April when the air temperature is relatively high, so that the germination rate of the tubers can reaches 90% or above; the decomposed cow dung is covered in winter of the same year, so that not only is the supply of nutrientsguaranteed, but also the subterraneous tubers are prevented from suffering from freeze injury; and the asexual propagation method adopted by the invention is simple in step, easy to implement and suitable for large-range popularization.

Description

technical field [0001] The invention belongs to the field of planting vegetables, and in particular relates to a method for asexual propagation of yanghezi. Background technique [0002] Yanghe ginger is a perennial herbaceous plant belonging to Zingiberaceae, also known as Yanghe, fencao, and wild ginger; the plant is about 1.5 meters high, with thick stems, well-developed root system, vigorous growth, light yellow rhizomes, needle-shaped Or narrow and long oval leaves, inflorescence color yellow bracts bright red or purple. It grows in Hubei, Sichuan, Anhui, Jiangsu, Zhejiang, Hunan, Jiangxi, Guangdong, Guangxi, Guizhou and other places in China. It belongs to shade-tolerant plants. It is wild and has been cultivated in large quantities. Rich in various amino acids, proteins and cellulose, the tender rhizomes contain α-pinene, β-pinene, β-phellandrene and other substances. The inflorescence part can be eaten as a vegetable, which is an anti-cancer and health-care wild ve...

Problems solved by technology

[0003] There are two ways to reproduce Yanghe ginger, one is to sow seedlings with seeds, the germination rate of seeds is low, and the seedling period is long (180-220 days); Dig up, cut each piece of 2-3 buds as propagation material, and plant tubers from December of the current year to February of the next year. The problem is that the temperature is low, the tuber germination rate is low, and the survival rate is below 85%.
