A kind of high-efficiency cultivation method of Tsaoguo seedlings

Abstract

The invention discloses an efficient cultivation method for Amomum tsaoko seeds and seedlings and belongs to the technical field of industrial crop cultivation. Due to the adoption of technologies such as constant-temperature and high-humidity storage in a darkroom, chemical combined regulation as well as germination acceleration and rooting, the dormancy of Amomum tsaoko seeds is effectively broken, the after-ripening and germination of the seeds are accelerated, and the germination rate of the seeds is remarkably increased; and due to the adoption of technologies such as selection of parentplants of high-yield Amomum tsaoko cultivated species, precise quantitative sowing and secondary intensified cultivation, the quality of the Amomum tsaoko seeds and seedlings is remarkably improved, the fruit yield of adult plants is remarkably increased, furthermore, the germination rate of the Amomum tsaoko seeds is larger than or equal to 90.0%, the number of required days is reduced by 20 as comparison with that of a traditional method, the cultivation period of the seeds and the seedlings on a seedbed is shortened by 120 days, the germination rate of the seeds reaches 91.3%, the survivalrate achieved after the seeds and the seedlings are transplanted reaches 98.0%, and the yield of dried fruits on the single plant growing on the third year after under-forest transplantation of the seeds and the seedlings is increased by 50% or above. The cultivation method disclosed by the invention has the advantages such as high seed germination speed, short cultivation time, good seed and seedling quality as well as high under-forest transplantation survival rate and fruit yield and is capable of promoting the production application of Amomum tsaoko and wide in market prospect.

Description

technical field [0001] The invention relates to the technical field of economic crop cultivation, in particular to a method for efficiently cultivating grass fruit seedlings. Background technique [0002] Tsaoko (Amomum tsaoko Crevost et Lemarie) is a perennial evergreen herbaceous plant belonging to the genus Cardamom of Zingiberaceae. The essential oil extracted from Tsaoko fruit is widely used in medicine and spice industry. Dried fruit can be used as Chinese herbal medicine, dry damp and warm, treat abdominal distension and pain, fullness and vomiting, malaria cold and heat, plague and fever. Soufeng Pills, Yishen Pills, Kaiyu Shugan Pills, Kuanxiong Lige Pills, Jiebai Pills, etc. In addition to being commonly used as a traditional Chinese medicinal material, Tsao Guo is also one of the bulk edible condiments, and its consumption is greater than that used in medicine. With people's health needs and the advancement of science and technology, Tsao Guo will be used more an...

Problems solved by technology

At present, the Tsaoguo species used in production are still semi-wild species. Under the premise that no good new varieties have been bred, the requirements for environmental conditions in each link of Tsaoguo growth are extremely harsh. At the same time, various places are collecting seeds, The seedling cultivation links such as sowing and seedling cultivation are highly random and the technology is not standardized. In the end, it generally shows low benefit phenomena such as large amount of seeds used for sowing, long seedling cultivation cycle, poor seedling quality, and low yield per plant after transplantation, which directly affects grassland.
