Problems solved by technology

Although the soil pollution in the undergrowth is much lower than in the farmland, the clean soil conditions still do not allow a high rate of spore germination

Embodiment 1

[0029] The operation steps are as follows:

[0030] 1) Spore collection and storage: Bracken spore powder grows on the edge of the bottom of the blade. When the spore powder on the edge of the blade turns yellow or dark green, select mature leaves with seed clarity ≥ 60%, cut them out and put them in a paper bag, After the bracken spores are collected, dry them in the air at 25°C for 40 hours, sieve them through a 500-mesh fine sieve to obtain the bracken spore powder, and place the spore powder at -25°C to freeze for later use;

[0031] 2) Preparation before sowing: Before sowing, take out the spore powder and soak in cold water at 15°C for 5 hours, then place it at -35°C for 100 hours, then place the frozen spore powder at -5°C for 7 days, and finally Sowing can be done after 30 hours at 10°C;

[0032] 3) Heating treatment of the culture medium: select 100kg of oak, elm, birch and willow in any ratio and mix them, cut them into 3-7cm segments, put them into a combustion fur...

Embodiment 2

[0040] The operation steps are as follows:

[0041] 1) Spore collection and storage: Bracken spore powder grows on the edge of the bottom of the blade. When the spore powder on the edge of the blade turns yellow or dark green, select mature leaves with seed clarity ≥ 60%, cut them out and put them in a paper bag, After the bracken spores are collected, dry them in the air at 26°C for 45 hours, sieve them through a 400-mesh fine sieve to obtain the bracken spore powder, and place the spore powder at -22°C to freeze for later use;

[0042] 2) Preparation before sowing: Before sowing, take out the spore powder and soak in cold water at 10°C for 6 hours, then place it at -38°C for 95 hours, then place the frozen spore powder at -5°C for 7 days, and finally Sowing can be done after 30 hours at 10°C;

[0043] 3) Heating treatment of the culture medium: select 80kg of oak, elm, birch and willow in any proportion and mix them, cut them into 3-7cm segments, put them into a combustion ...

Abstract

The invention belongs to the field of agricultural cultivation, and particularly relates to a method for artificially propagating pteridium aquilinum spores for seedling growth. The method comprises the specific steps of (1) collecting and storing the spores; (2) performing preparation before sowing seeds; (3) heating a culture medium; (4) heating humus soil; (5) preparing culture soil; (6) tilling a land; (7) sowing the pteridium aquilinum spores; (8) cultivating the pteridium aquilinum spores; (9) acquiring pteridium aquilinum spore seedlings. According to the method, the key problems that the propagating germination rate and the survival rate of the pteridium aquilinum spores are not high are solved, the pteridium aquilinum spores can be quickly propagated, the effects of high yield and high efficiency are achieved, the germination rate of the pteridium aquilinum spores can reach 90 percent, the survival rate reaches 95 percent, and the transplanted seedlings are easier to survive; meanwhile, the cost is reduced, and the profits are increased.

Description

technical field [0001] The invention belongs to the field of agricultural cultivation, in particular to a method for artificially propagating bracken spores into seedlings. Background technique [0002] Bracken is one of the main wild vegetables in our country, and its young leaves and petioles are the edible parts, which are deeply loved by people. Due to people's excessive collection of wild bracken, the normal growth and reproduction of bracken can not be caused, resulting in the sharp shrinkage or even exhaustion of wild resources, and the supply of bracken products is in short supply. The artificial cultivation and wild tending of bracken have broad market prospects. Bracken belongs to higher spore plants. It has no seeds and can only reproduce asexually by spores and rhizomes. However, spore reproduction is difficult and has a long cycle, so it is generally not used in production. The rhizomes of bracken in the wild are relatively thin, poor in quality, low in reprodu...
