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 se

Embodiment 1

[0028] A method for efficiently cultivating Tsaoguo seedlings, comprising the steps of:

[0029] (1) Selection of the cultivar parent plant: the plant age after plant transplantation is selected between 3-5 years, the overall plant development is good, the growth is vigorous, the result is many, no disease and insect pest, no mechanical damage of the parent plant, and the parent plant The shape of the small fruit on the ear of the fruit is close to round or oval in the mature stage of the fruit. The fruit length of the small fruit is 3.0-3.5cm, the diameter of the middle part is 2.5-3.0cm, the ratio of the length to the diameter of the middle part is between 1.0-1.5, and the thousand-grain weight of the seeds 60-70g, the peel is bright red at the mature stage, and the seeds are broken and emit a strong spicy taste;

[0030](2) Ear picking and post-ripening storage: In the late October to early November of each year, the fruit ears are picked on the mother plant selected in ste...

Embodiment 2

[0037] The difference between the method of embodiment 2 and embodiment 1 is that in embodiment 2, the mother plant is not judged and selected during seed collection, but the mother plant is randomly selected, and the remaining steps and methods are completely consistent with embodiment 1.

Embodiment 3

[0039] The method of embodiment 3 is different from embodiment 1 in that: embodiment 3 does not carry out chemical combination treatment and regulation to the seed when step (3), but the seed gained in step (2) is stirred evenly with plant ash, then with Both hands are repeatedly rubbed several times; Embodiment 3 does not carry out accelerating germination and rooting during step (4), but directly carries out sowing after processing with plant ash, and fully consistent with embodiment 1 in all the other steps and methods.

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...
