Problems solved by technology

However, due to a large number of unplanned harvesting and pruning of wild Yangtong in China in the past ten years, the quantity of this resource has become less and less, and the quality has become worse and worse. It is already facing the situation of depletion of wild resources.

Embodiment 1

[0013] Embodiment one (twig cutting):

[0014] A. Land preparation

[0015] ① Seedbed selection and site preparation: The land for seedling cultivation should be selected in slightly acidic sandy soil with good drainage and irrigation, which is high in the northwest and low in the southeast. One end east, one end west), the seedbed is 1.4 meters wide, the ditch is 0.4 meters, and the ditch is 0.3 meters deep. Remove all weeds, impurities, and clear stones. Use 12 grams of compound fertilizer per square meter of bed surface as base fertilizer, and use 5 grams of carbofuran. Prevention and control of underground pests; the seedbed is covered with fresh clay loess 1.1 meters wide and 5 centimeters thick, and the seedlings can be grown by cuttings. Water the night before the cutting, but it should not be watered too much, if the ground is wet, it should not be watered.

[0016] ②Set up a 2.5-meter-high sunshade shed, or a steel-frame shed cover, and cover it with a sunshade net ...

Embodiment 2

[0027] Embodiment two (hard branch mildew season cutting):

[0028] The difference from Example 1 is that in June, the young shoots with a branch age of 60 to 80 days were cut into 3 to 5 cm sections, and each section retained 2 axillary buds and 2 healthy mother leaves; When cutting seedlings into sections, it is better to cut at the axillary buds, which is conducive to rooting. Branches with green leaves cannot be used. The larger the leaf surface, the greater the photosynthesis and the faster the rooting. The rest of the operations are the same as those in the examples.

[0029] According to the above-mentioned operation method, the survival rate reaches more than 87%, and the height of the annual poplar cutting seedlings can reach 33-48 centimeters; it is suitable for transplanting afforestation seedlings.

Embodiment 3

[0030] Embodiment three (cutting of hard branches in early autumn):

[0031] The difference from Example 2 is that the young shoots of the current year with a branch age of 60 to 80 days are used to prepare the scion in the early autumn of September, and all the other operations are the same as in the example.

[0032] According to the above-mentioned operation method, the survival rate reaches more than 89%, and the height of the annual Yangtong cutting seedlings can reach 31-46 centimeters; it is suitable for transplanting afforestation seedlings.

Abstract

The poplar and phoenix cutting and seedling growing method includes collecting the same year twig as cutting shoot in the time from May to September, nourishing treatment of the cutting shoot, planting to wind sheltering and sunny seedling bed of slightly acid soil, covering with film to maintain humidity, and covering with shed for further growth of the seedling. The present invention obtains poplar and phoenix seedling with the excellent characteristic of the mother plant maintained for afforestation by means of asexual propagation.

Description

【Technical field】 [0001] The invention belongs to an artificial breeding method of plants, in particular to a method for growing seedlings by cuttings of poplar. 【Background technique】 [0002] Yangtong (Latin name: Cleyera laponica Thunb.), evergreen tree species, wild, distributed in Zhejiang, Jiangxi, Anwei and other Jiangnan provinces, can grow at an altitude of 50-1000 meters, mostly at 300-600 meters; The plant is glabrous except for the flowers, the branchlets are angular, and the terminal buds are prominent; the leaves are herbaceous, elliptic to obovate or long elliptic-ovate, 7-8 cm long, 2-5 cm wide, the entire surface is smooth, and the back is yellow; From May to June, pale yellow flowers bloom in leaf axils; solitary or clustered leaf axils, 6 mm in diameter; 2 bracts, tiny; 5 sepals, with eyelashes; 5 petals, about 8 mm long, entire, stamens about 25, flowers Core with transparent bristles, ovate-elliptic, less than 1.5mm long; ovary 2-3 rooms, style top 2-3-...
