Problems solved by technology

Previous studies have shown that the dormancy factors of Cyclocarya paliurus seeds are diverse and belong to the comprehensive deep dormancy type: the hard outer shell is the main reason for its forced dormancy, which not only restrains the embryo, but also affects the air permeability, but it still has water permeability. Secondly, there is still physiological dormancy in the seeds, and the seed coat hinders the water and air exchange between the embryo and the outside world to a certain extent; at the same time, a large amount of inhibitory substances accumulate in the seed coat, making the young embryo enter a deep dormancy state

Embodiment

[0024] A method for improving the germination rate of Cyclocarya paliurus seeds, comprising the steps of:

[0025] 1) Remove the seed coat;

[0026] 2) Tidy up the seedbed

[0027] 3) Fertilization in the early stage

[0028] 4) Mid-term management

[0029] 5) Emergence management

[0030] Through the above steps, the germination rate of Cyclocarya paliurus seeds can be increased to more than 95%.

[0031] In step 1), air-dry the Cyclocarya paliurus seeds harvested in the field, and use a ball mill to grind the air-dried seeds. During the grinding process, add a certain amount of lime powder, water, and edible acid. The ratio is 100 kg of seeds, and add 5 1 kilogram of lime powder, 15 kilograms of clear water, add 35 kilograms of edible acid, the pH value of edible acid is 3, ball milling time is 5 hours, and temperature is room temperature, through this method treatment, can obtain the Cyclocarya paliurus seed that removes testa.

[0032] In step 2), when selecting the e...

Abstract

The invention discloses a method for increasing the seed germination rate of cyclocarya paliurus. The method comprises the steps that seed coats are removed, a seedbed is cleared up, early-stage fertilizer applying and middle-stage managing are conducted, and then seedling emergence managing is conducted. Therefore, the seed germination rate of the cyclocarya paliurus can be greatly increased, it can be guaranteed that the germination rate is 95% or above, and the cyclocarya paliurus breeding problem is solved. The method is simple and easy to operate, low in cost and good in benefit.

Description

technical field [0001] The invention belongs to the field of agricultural planting, and in particular relates to a method for improving the germination rate of Cyclocarya paliurus seeds. technical background [0002] Qingqian willow, alias: money tree, hemp willow, green money plum, mountain hemp willow, mountainized tree. Juglandaceae and Cyclocarya genus plants are found in many provinces in southern my country, mostly in sporadic distribution. Cyclocarya paliurus is a rare tree species that survived the Quaternary Glacier. It is a unique single-species arbor plant in my country. It is one of the endangered plants under national key protection and belongs to the third category of protected plants. Cyclocarya paliurus is widely used, and it is a precious tree species with great prospects for development and utilization. Studies have found that trace elements such as manganese, iron, copper, zinc, selenium, chromium, alum, germanium, etc. are important for Cyclocarya paliu...
