Embodiment 1

[0033] A method for promoting the seed germination of endangered plant Hainan Fengchuannan, the main steps are as follows:

[0034] (1) Seed collection: After harvesting Hainan Fengchuan Nan fruit, place it in a ventilated place to dry in the shade, take out the seeds after the peel is cracked, remove the aril, spray 2000 times of the original trichlorfon powder to kill the insects for 1 hour, and then rinse with clean water;

[0035] (2) Seed selection and treatment: select seeds with a single weight ≥ 5.0 g, and place them in a water bath at 35 °C for 6 hours;

[0036] (3) Sand bed preparation: choose a plastic box with a length x width x height of 530mm x 350mm x 140mm as the culture container, spread fine sand with a thickness of 5 cm in the plastic box, and spray 0.2% potassium permanganate by mass fraction Disinfect; wipe the plastic box with 75% alcohol for disinfection before using it;

[0037] (4) Sowing: Put the seeds after the water bath into the culture container ...

Embodiment 2

[0042] According to the method of Example 1, the endangered plant Hainan Fengchuannan seed germination is carried out, the difference is that the raw material formula of the nutrient solution in step (5) is: 600 mL Hoagland's nutrient solution+200 mL 400 mg / L GA 3 +100 mL 10.0mg / L zeatin + 50 mL 2000 mg / L 50% carbendazim by volume + 50 mL 1000 mg / L methanol crude extract of P.

Embodiment 3

[0044] According to the method of Example 1, the endangered plant Hainan Fengchuannan seed germination is carried out, the difference is that the raw material formula of the nutrient solution in step (5) is: 600 mL Hoagland's nutrient solution+200 mL 200 mg / L GA 3 +100 mL 10.0mg / L zeatin + 50 mL 2000 mg / L 50% carbendazim by volume + 50 mL 1000 mg / L methanol crude extract of P.

Abstract

The invention provides a method for promoting the seed germination of endangered plant P. chinensis, including seed collection, seed selection and treatment, sand bed preparation, sowing, nutrient solution preparation and spraying, and post-sowing management procedures. After the nan fruit, after the peel is cracked, the seeds are taken out. After the seeds are washed with insecticidal water, the seeds with a single grain weight of ≥ 5.0 g are screened out, and the seeds are sown in the prepared culture container in a water bath at 35 ° C for 6 hours. After sowing, the culture container is placed in the Put it in the incubator, and spray the nutrient solution into the culture container once a day from 8:00 to 9:00. Aiming at the physiological characteristics of Hainan Fengchuan seeds, the invention completes the morphological post-ripening process under the condition of 35 ° C water bath for 6 hours, combined with the spraying treatment of nutrient solution, the seed germination time is significantly shortened, the germination rate is significantly improved, and the operation is simple and rapid. The neat features meet the requirements of large-scale cultivation and standardized production of Hainan Fengchuannan.

Description

technical field [0001] The invention belongs to the technical field of forest tree seedling cultivation, and in particular relates to a method for promoting the germination of endangered plant Phoebe chinensis seeds. Background technique [0002] Hainan wind blowing Nan ( Horsfieldia hainanensis Merr.) belongs to the family Myristacaceae, Horsfieldia Willd.), a unique evergreen tall tree distributed in a narrow area in China. Now it is mainly distributed in Guangxi, Yunnan, Hainan and other regions, mostly in the shady valleys with an altitude of 400-450 m at the junction of China, Myanmar and Vietnam. Hainan Fengchuannan is an iconic species of humid tropical rainforest. It is of great value to the study of tropical rainforest flora, geographical distribution, ecological habits and the protection biology of endangered plants in tropical rainforest areas. At the same time, the leaves and bark of this plant can be used for treatment Infantile chancre, its seeds have a v...
