Problems solved by technology
Especially in some northern areas, the temperature in spring is low, the soil moisture content is low, saline-alkaline, and lack of nutrients, which is not conducive to large-scale sowing and reproduction of camphor
[0003] At present, there are relevant documents disclosing some technologies for improving the germination rate and early germination of camphor seeds, but the applicant has repeatedly verified the technology through the disclosed technology, and the germination rate of camphor seeds in northern my country cannot be obtained as described in the disclosed technology. The germination rate is more than 80%, and the germination rate of seeds can only reach 55%-65% through the existing technology.

Embodiment Construction
[0013] The present invention will be described in detail below in conjunction with the embodiments.
[0014] This embodiment is based on the process technology obtained through repeated tests for the low temperature in spring in the northern region, low soil water content, partial salinity, lack of nutrients and other factors, and specifically includes the following steps:
[0015] (1) Seed collection and seed production
[0016] Cinnamomum camphora seeds should be selected from adult healthy trees with normal growth. In early November each year, when the fruits mature to purple-black, harvest them in time, soak them in warm water at 35-40°C for 2 days and then scrub them to remove the peel, rinse off the testa and For the seeds floating on the water, the plump seeds that sink to the bottom are rinsed with water, mixed with plant ash and degreased for 12 hours, washed and dried.
[0017] (2) Seed stratification treatment
[0018] The seeds are soaked in 0.5% potassium permanganate solu...

The invention discloses a technology utilizing hydrogen peroxide to improve the germination rate of cinnamomum camphora. The technology mainly comprises the following steps: (1) harvesting seeds and processing seeds; (2) performing seed stratification; (3) accelerating seed germination; (4) sowing the seeds on a seed bed; (5) carrying out seedling stage management; (6) transplanting seedlings and performing field planting; (7) managing and nursing nursery stocks. Through a hydrogen peroxide treatment, the seed permeability is improved, and thus water and oxygen gas can enter the seed embryo more easily. The seeds, which are processed by H2O2 (5%) for 4 to 6 hours, can germinate 7 to 10 days before the unprocessed seeds, the germination potential is increased by 13.2%, and the germination rate is increased by 20.1%.
Description
Technical field [0001] The invention relates to the technical field of plant seed germination, in particular to a technology for improving the germination rate of camphor seeds by using hydrogen peroxide. technical background [0002] Cinnamomum camphora is an evergreen tree with a wide canopy, dense foliage, and majestic momentum. It is an excellent street tree and shade tree. It has a strong ability to smoke dust, conserve water, stabilize soil and prevent sand and beautify the environment. Camphor tree likes light and is slightly tolerant to shade; it likes warm and humid climate, has low cold tolerance, and has less strict requirements on the soil. It is more resistant to water and humidity, but is not resistant to drought, barren and saline-alkaline soil. Flowering period from April to May, fruit period from October to November; the small spherical fruit becomes dark purple after maturity, with a diameter of about 0.5 cm. Cinnamomum camphora seeds contain germ-inhibiting su...
