Embodiment 1

[0018] Seed coat treatment: Put 50Kg of mature and plump seeds in 5mol / L concentrated sulfuric acid and soak for 5min.

[0019] Secondary treatment: Put the seeds obtained in step (1) into 0.1mol / L potassium permanganate solution and soak for 7 minutes.

[0020] Pregermination: put the seeds after secondary treatment into potassium nitrate solution with a mass concentration of 2%, and soak for 50 days.

[0021] Transplanting and planting: select germinated seeds and transplant them to the field.

[0022] It has been determined that the germination rate of the seeds of the tea seed in Example 1 is 40%, which is much higher than the germination rate of the seed of the tea seed of 22%.

Embodiment 2

[0024] Seed coat treatment: put 35Kg of mature and plump seeds into 10mol / L concentrated sulfuric acid and soak for 2min.

[0025] Secondary treatment: Put the seeds obtained in step (1) into 0.05mol / L potassium permanganate solution and soak for 10 minutes.

[0026] Pregermination: put the seeds after secondary treatment into potassium nitrate solution with a mass concentration of 1%, and soak for 50 days.

[0027] Transplanting and planting: select germinated seeds and transplant them to the field.

[0028] After determination, the germination rate of the tea seed of Xiaogou catechu in Example 1 is 35%.

Embodiment 3

[0030] Seed coat treatment: put 35Kg of mature and plump seeds into 7mol / L concentrated sulfuric acid and soak for 4 minutes.

[0031] Secondary treatment: Put the seeds obtained in step (1) into 0.08mol / L potassium permanganate solution and soak for 5 minutes.

[0032] Pregermination: put the seeds after secondary treatment into potassium nitrate solution with a mass concentration of 3%, and soak for 250 days.

[0033] Transplanting and planting: select germinated seeds and transplant them to the field.

[0034] After determination, the germination rate of the seeds of the tea seed in Example 1 is 31%.

[0035] The invention can remarkably improve the germination rate of the tea seed, and has great significance for protecting the tea species.

Abstract

The invention discloses a method for planting berchemiella wilsonii nakai to solve the problems of low germination rate and breeding difficulty of berchemiella wilsonii nakai. The method includes: firstly, treating seed coat, namely placing seeds in concentrated sulfuric acid 5-10mol / L for soaking for 2-5 minutes; secondly, secondarily treating the seeds, namely placing the seeds treated in the step one into potassium permanganate solution 0.05-0.2mol / L for soaking for 5-10 minutes; thirdly, accelerating germination, namely placing the seeds treated in the step two into potassium nitrate solution with 1%-3% mass concentration for soaking for 20-50 days; and fourthly, performing transplantation and field planting, namely transplanting the germinating seeds to a field. By means of treatments such as seed coat treatment, germination acceleration and the like for the seeds, the germination rate of berchemiella wilsonii nakai can be improved evidently, and significance on protecting berchemiella wilsonii nakai is achieved.

Description

technical field [0001] The invention relates to the field of agricultural production, in particular to a planting method of Chamomile chinensis. Background technique [0002] Xiaogoucatecha is a deciduous shrub, 6-12 meters high, its bark is gray-black, longitudinally split; branchlets are light reddish brown, glabrous, with obvious lenticels, Xiaogoucatecha has longitudinal cracks. It is mainly distributed in the broad-leaved forests at an altitude of 900 to 1,200 meters in some areas of Hubei and Anhui. It is unique to my country and is a national second-class protected plant, which is an endangered species. [0003] The seeds of C. chinensis are less fully developed, and the water permeability of the tea seed coat is poor. At the same time, there are germination inhibitors in different parts of the seeds, resulting in a low germination rate of C. catechu seeds and difficulty in reproduction, resulting in small Gou catecha is facing endangered situation.
