Problems solved by technology
[0005] In order to solve the above-mentioned technical problem that the trunk of Zinan is not obvious, short or has no trunk in the process of planting and breeding, the present invention provides a technical method for solving the problem of not obvious, short or no trunk in the process of planting and breeding of Zinan ( figure 1 , 2), the technology provides shady conditions for the growth of Zinan by mixed planting of Zinan and small arbor Lagerstroemia indica, to shape the upright trunk of Zinan early growth, and promote the elongation of Zinan trunk at the same time ( image 3 ,Table 1)

Embodiment 1
[0027] Embodiment 1: A kind of mixed planting method of shaping the upright trunk of Zinan seedlings
[0028] Planting materials: Zinan seeds were collected in the Institute of Botany, Chinese Academy of Sciences, Jiangsu Province, and sowed in the base of Changzhou Guomei Agricultural Technology Co., Ltd. The crape myrtle seedlings were provided by Changzhou Guomei Agricultural Technology Co., Ltd.
[0029] 1) Collection and storage of Zinan seeds:
[0030] From late November to early December, when the outer testa of Zinan seeds turns from green to purple-brown, it means that the seeds are mature and can be collected, and choose to collect plump seeds from excellent mother trees more than 15 years old. The collected seeds should be removed from inferior fruits. The specific method is to put them in water, and those that float on the water surface are inferior fruits. After removing the inferior fruit, wear latex gloves on both hands, rub the fruit, separate the peel and see...

The invention discloses a mixed planting method for growing vertical main trunks of seedlings of phoebe sheareri (Hemsl.) gamle. According to the method, dungarunga crape myrtles are transplanted at the same month during germination acceleration of the seeds of the crape myrtles, and two years later, the seedlings of phoebe sheareri (Hemsl.) gamle are transplanted from a seedling nursery garden tothe places where the dungarunga crape myrtles are planted, wherein one seedling of phoebe sheareri (Hemsl.) gamle is planted at the center of every four crape myrtles. The method can effectively prevent the situations that during the growth of the seedlings of phoebe sheareri (Hemsl.) gamle, since too many side branches grow up, the main trunks are not obvious in growth condition and low in height, or the main trunks do not exist; by means of mixed planting of phoebe sheareri (Hemsl.) gamle and the dungarunga crape myrtles, the vigorous growth of the side branches of phoebe sheareri (Hemsl.)gamle can be successfully prohibited, saplings of phoebe sheareri (Hemsl.) gamle with obvious, high and straight main trunks can be achieved, and technical support can be provided for cultivation promotion of precious timber forests of phoebe sheareri (Hemsl.) gamle.
Description
technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to a method for shaping the upright trunk of Zinan seedlings by using the mixed planting of Zinan and small arbor crape myrtle. Background technique [0002] Phoebe sheareri, also known as Zijinnan, Jinxinnan, and Jinsinnan, is an evergreen broad-leaved tree species of the genus Phoebe in the family Lauraceae. It is naturally distributed in mountainous broad-leaved forests below 1000m above sea level in the south of the Yangtze River Basin. Zinan tree is beautiful in shape and evergreen in all seasons, and can be used as a shade tree, greening, and landscape tree; its wood is hard and corrosion-resistant, and it is a world-renowned precious timber tree species, and it is also the main source of "golden nanmu". Zinan is a shade-tolerant species in the mid-subtropical zone. Although it can grow in places exposed to sunlight, it is not as good as in shade. Plantin...
