Problems solved by technology

Using a large number of spores produced by Osmanthus vetch to carry out artificial propagation and seedling cultivation is an effective way to improve the reproduction coefficient of Osmanthus vetense. The quality of artificial cultivation is closely related to the quality of spores, seedling substrates, management methods, etc. Most of the existing seedling cultivation methods have spore germination Low seedling rate, long seedling time, poor seedling physique, etc., and it is difficult for the seedlings to grow normally under the condition of higher than 30°C, which limits the cultivation and promotion of Osmanthus cabbage

Embodiment 1

[0042] A method for cultivating high temperature-resistant vetch seedlings, comprising the steps of:

[0043] (1) Spore collection:

[0044] In the middle of May every year, when 70% of the spore leaves of Osmanthus vetch are unfolded and the lower part starts to turn yellow, they are picked and placed on newspapers in a ventilated place indoors to allow them to mature and dry naturally. After 3 days, the spores are scattered on the paper. After the sundries are removed through the sieve, the spores are collected for later use;

[0045] (2) Spore pretreatment:

[0046] a. Put the spores collected in step (1) into distilled water, wash them thoroughly, put them at 23°C for 17 minutes, and take them out for later use;

[0047] b. Simultaneously apply blue light and ultrasonic treatment to the spores treated in operation a, the wavelength of the blue light is 458nm, and the light intensity is 160 μmol·m -2 ·s -1 , the frequency of the ultrasonic wave is 34KHz, and it is tak...

Abstract

The invention discloses a method for culturing high temperature-resistant osmunda japonica seedlings. The method comprises the following steps: a step (1) of spore collection; a step (2) of spore pretreatment; a step (3) of seedling culture substrate preparation; a step (4) of spore seeding; and a step (5) and management after seeding. Each growth condition during osmunda japonica spore seedling culture is reasonably controlled and matched, temperature resistance characteristics of the seedlings are improved well, so that the seedlings can still grow well under the conditions of 30-35 DEG C, the germination rate of osmunda japonica spores can be remarkably improved, the germination duration is shortened, and the method has good popularization value.

Description

technical field [0001] The invention belongs to the field of planting, and in particular relates to a method for cultivating high-temperature-resistant weed vegetable seedlings. Background technique [0002] Weicai is a kind of tender petiole of perennial herbaceous fern in Osmanthaceae. It is rich in protein, multivitamins, potassium, calcium, phosphorus and other trace elements, as well as rare ingredients such as ecdysterone and tannin. The vegetable is rich in nutrition, bitter and cool, has the effects of calming the nerves, lowering blood pressure, anti-cancer, clearing away heat, and losing weight, and has obvious inhibitory effect on viruses such as influenza and Japanese encephalitis. The rhizome can extract starch, and the micro-vegetable is crisp and Less fiber, delicious and refreshing, rich in nutrition, its protein inorganic salt and ascorbic acid content are more than ten times higher than ordinary vegetables. Utilizing a large number of spores produced by Os...
