Embodiment 1

[0024] Initial observation after embodiment 1 hair tree saplings fixed dry treatment

[0025] In the autumn of 2010, the seeds were picked from the Sun Yat-sen Mausoleum Scenic Spot in Nanjing. In the winter of 2011, they were cultivated in the nursery of Jiangsu Academy of Forestry Sciences (Dongshan Bridge, Jiangning District, Nanjing) according to technical steps such as warm water soaking, peeling and meat extraction, sand storage for germination, and sowing and tending. There are 963 1-year-old saplings. In March 2012, 400 of these young trees were transplanted to the School of Horticulture of Jinling Institute of Science and Technology (Xiaozhuang Xingzhi Garden, Qixia District, Nanjing). In autumn, 100 well-grown plants were selected and carried out top removal and fixed stem treatment, and the top branches above 2.0 meters of young trees were cut off to control the trunk height of young trees. Due to the lack of appropriate thinning and retraction treatment in time, t...

Embodiment 2

[0026] The sapling observation after the follow-up shaping technology measure of the present invention is taken after embodiment 2 hair sapling sapling is fixed dry

[0027] The 100 plants after transplanting and planting in 2012 were selected to carry out the treatment of top removal and fixed trunk simultaneously, and the top branches of the young trees above 2.0 meters were cut off to control the trunk height of the young trees. After one year of cultivation, the following operations were carried out subsequently:

[0028] ⑴Retaining branches in layers: Use branch shears to trim the side branches on the trunk at a certain interval and keep them in layers. The interval of pruning is 40cm, and the number of layers retained is 4. From the top, it is divided into the top layer, the second top layer, the middle layer, and the bottom layer; Within 8cm.

[0029] ⑵Mechanical extension: draw a circle around the base of the young tree with a radius of 60cm, nail 6 wooden stakes eve...

Embodiment 3

[0033] The sapling observation after the shaping and tending measures of the present invention have been taken after the saplings of embodiment 3 are fixed and dry

[0034] The 100 plants after transplanting and planting in 2012 were selected and simultaneously carried out top removal and fixed stems, layered branch retention, mechanical branch extension, misdirected branch thinning, retraction and strong branch treatment, and the following tending technical measures were carried out successively:

[0035] ⑸Fertilizing and nourishing: Since 2013, during the vigorous growth period of saplings (May to September), topdress the soil twice. The material used is nitrogen-phosphorus compound fertilizer, and the dosage is 0.2 kg per plant. The method is to dig holes around the roots and bury the soil for fertilization, and then water appropriately after application; Fertilizer (Wolchun) mixture, the two are mixed at a ratio of 10:1, dissolved in water, and the spraying concentration i...

Abstract

The invention provides a cornus walteri layering type crown shaping and cultivation method and relates to the technical field of forestry production. The method comprises the following steps of (1) picking up tops and fixing trunks; (2) layering and retaining branches; (3) mechanically stretching the branches; (4) thinning the branches in a staggered way; (5) retracting strong branches; (6) performing topdressing and promoting strength; and (7) maintaining roots. According to the method, in order to meet the requirements that the yield of fruit and seed is increased and convenience for people to pick is achieved in forest stand cultivation for cornus walteri, the cornus walteri tree shape is properly dwarfed, and proper artificial cultivation measures are taken to enable the cornus walteri branches and leaves to be expanded, spread in a layered way, radiated in a staggered way and extended in a limited way, so that sunlight is received to a greatest degree, development of lateral branches is promoted and the fruit yield of a single plant is increased. By the method, the crown is completely dwarfed on the premise of ensuring that the yield is not reduced, fruit hand-picking is benefited, the labor cost is effectively reduced and the production efficiency of the industrial base is improved.

Description

technical field [0001] The invention relates to the technical field of forestry production, in particular to a method for shaping and cultivating a layered tree crown of trichomes. Background technique [0002] Cornus walteri is an important woody oil tree species that has developed rapidly in my country in recent years. Trichosanthes is favored by forest farmers for its fast seedling growth, high oil content and high economic value. It is widely cultivated in Northeast, Northwest, North China, and Jiangnan of China, and has become a new direction for the development of bioenergy tree species in recent years. The oil yield of the whole fruit of Maochun is more than 33%, and the oil content of the pulp is as high as 57.35%. Grease is not only edible, but also used as lubricating oil for machinery and watches, and is also a good raw material for paint. The residue after oil extraction is excellent feed and fertilizer, and the bark and leaves can be extracted to copy glue. Th...
