Problems solved by technology

[0003] At present, the source of bracken products mainly depends on harvesting wild bracken, which is difficult to meet the growing market demand, and there are problems such as uneven product quality and restrictions by the external environment. If wild rhizomes are collected for domestication and cultivation, wild resources will be destroyed and its ecological environment, it is difficult to meet the development of the market and the situation

Embodiment 1

[0015] (1) Collection of mature spores of bracken: After the spores of bracken are mature in September-October, cut off the leaves with scissors at the base of the petiole, put them in an envelope or other paper bags, and dry them in the air for 3 days. The spores will be ejected, and the mature spores of bracken will be obtained after sieving. (2) Substrate preparation and disinfection: The volume ratio of the substrate is vermiculite: perlite: peat = 4:2:1, mix well, completely wet the substrate with water, wrap the prepared substrate with newspaper or other paper , put it in an autoclave, and sterilize at 121°C for 25 minutes. This is mainly to kill the weeds and other organisms in the matrix, which is beneficial to the growth of bracken spores. (3) Spore sowing: spread the sterilized matrix obtained in step (2) on the seedling tray, the thickness is 12cm, and then evenly spread the bracken spores (which can be mixed with fine sand to facilitate the even spreading of the sp...

Embodiment 2

[0017] (1) Collection of mature spores of bracken: After the spores of bracken are mature in September-October, cut off the leaves with scissors at the base of the petiole, put them in envelopes or other paper bags, and dry them in the air for 4 days. The spores will be ejected, and the mature spores of bracken will be obtained after sieving. (2) Substrate preparation and disinfection: The volume ratio of the substrate is vermiculite: perlite: peat = 3: 1.5: 0.8, mix evenly, completely wet the substrate with water, wrap the prepared substrate with newspaper or other paper , put it into an autoclave, and sterilize at 121°C for 28 minutes. This is mainly to kill weeds and other organisms in the matrix, which is beneficial to the growth of bracken spores. (3) Spore sowing: spread the sterilized matrix obtained in step (2) on the seedling tray, the thickness is 14cm, and then evenly spread the bracken spores (which can be mixed with fine sand to facilitate the even spreading of th...

Embodiment 3

[0019] (1) Collection of mature spores of bracken: After the spores of bracken are mature in September-October, cut off the leaves with scissors at the base of the petiole, put them in an envelope or other paper bags, and dry them in the air for 3 days. The spores will be ejected, and the mature spores of bracken will be obtained after sieving. (2) Substrate preparation and disinfection: The volume ratio of the substrate is vermiculite: perlite: peat = 5: 2.8: 1.25, mix evenly, completely wet the substrate with clean water, and wrap the prepared substrate with newspaper or other paper , put it in an autoclave, and sterilize at 121°C for 30 minutes. This is mainly to kill the weeds and other organisms in the matrix, which is beneficial to the growth of bracken spores. (3) Sowing of spores: spread the sterilized matrix obtained in step (2) on the seedling tray with a thickness of 15 cm, and then evenly spread the bracken spores (which can be mixed with fine sand to facilitate th...

Abstract

The invention discloses a quick propagation seedling establishment method for bracken spore matrix, which is characterized by comprising the following steps: (1) collecting mature bracken spores, (2) allocating and sterilizing the matrix, (3) broadcast-sowing the spores, (4) culturing seedlings, (5) separating the seedlings, (6) acclimatizing the seedlings before transplanting, and (7) transplanting. By using the method, the germination rate of the bracken spores can reach 70 percent, the seedling transplanting survival rate is 99 percent, and the bracken seedlings can be quickly provided. The germination rate of the bracken spores can reach 70 percent, the seedling transplanting survival rate is 99 percent and the bracken seedlings can be quickly provided, so the method radically avoids damage to wild resources and ecological environment caused by collecting wild bracken rootstocks to affect propagation, has high propagation speed, and meets the requirement of large-scale and standardized development.

Description

technical field [0001] The invention provides a method for rapid propagation and seedling formation of bracken spore substrate, which belongs to the technical field of biology and ecology. Background technique [0002] Bracken is a Pteridaceae plant with high nutritional value. It can clear away heat and detoxify, lax the intestines, relieve qi and reduce phlegm; Active ingredients such as saponins and flavonoids have the functions of clearing away heat and detoxifying, diuretic and analgesic, hemostasis and killing insects. It is also widely used and can be eaten fresh or pickled. The fern powder made from the rhizome of bracken has a nourishing effect and can be used as a food substitute. It can also be made into cakes and vermicelli. Because wild bracken has a special fragrance, is rarely polluted and has many functions, it has become one of the important local products for foreign trade in my country, and enjoys the reputation of "the king of mountain delicacies" abroad...
