Problems solved by technology

Cultivating strong seedlings is the basis for promoting the cultivation and growth of Zhennan. The Zhennan seedlings cultivated by traditional seedling raising methods have a long slow root period after planting, low survival rate, and extremely slow growth after survival. After a few years, they will become old. small tree

Embodiment 1

[0023] The cultivation method of Phoebe zhennan seedlings of the present invention:

[0024] (1) Seed treatment: select new seeds with plump and uniform seeds and no damage from diseases and insect pests, with a thousand-grain weight of 300-345 grams. Soak the seeds with 0.1% potassium permanganate aqueous solution for 30 minutes before sowing, wash them with clean water and then use 100 ㎎ / L gibberellin Soak the seeds for 8 hours, take out the seeds and dry the surface;

[0025] (2) Disinfection of nutrient soil: loose and fertile sandy loam soil and peat 2:1 ratio, add 100 grams of 70% mancozeb wettable powder for every 100 kg of nutrient soil, and mix well;

[0026] (3) Planting: put a zhennan seed in each seedling paper cup. When planting, first punch a small hole with a small wooden stick, the depth is half of the nutrient soil, leave a 2cm space in the nutrient soil cup, and put the seeds After entering, cover the soil well, arrange the seedbeds neatly in the greenhouse ...

Embodiment 2

[0034] Zhennan seedling quality survey:

[0035] Before the seedlings came out of the nursery, 100 cups of seedlings were randomly selected to investigate the quality of the seedlings. The results are shown in Table 1.

[0036] Table 1 Statistical table of the results of sampling investigation of 100 zhennan seedlings

[0037] Seedling grade Ground diameter (cm) Seedling height (cm) Number of plants Ⅰ ≥0.3 ≥25 85 Ⅱ 0.2-0.29 15-24 15

[0038] Remarks: Ground diameter ≥ 0.3cm, seedling height above 25cm is Grade I seedling; ground diameter 0.2cm-0.29cm, seedling height 15cm-24cm is Grade II seedling.

[0039] According to statistics, among the zhennan seedlings cultivated by the method of the present invention, the I-grade seedlings account for 85%.

Abstract

The invention discloses a method for cultivating Machilus seedlings. The method comprises the following steps: (1) seed handling: carefully selecting seeds which are full and even in particle size and do not have insect diseases, before sowing the seeds, using acid aqueous solution of potassium permanganate to soak the seeds, cleaning the seeds with clear water and soaking the seeds with gibberellins, and taking out the seeds and air-drying the surfaces; (2) nutrient soil disinfection: after mixing loose fertile sandy loam with peat, adding Mancozeb wettable powder, and mixing the mixture to produce nutrient soil; (3) seed placement: loading the nutrient soil into seedling growing paper cups, putting the Machilus seeds into the paper cups, and watering the seeds; and (4) seedling stage management including nutrient supplement, moisture management and disinfection and disease prevention. Machilus seedlings cultivated with the method have developed root systems, flourishing leaves, and deep green leaf colors. The Machilus seedlings grow evenly and tidily without insect diseases, and the transplanting survival rate is more than 98%.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to a method for cultivating zhennan seedlings. Background technique [0002] Zhennan is a large evergreen tree belonging to the genus Phoebe, which is endemic to China and South Asia. It is a well-known precious timber tree species at home and abroad. It is hard, durable, excellent in corrosion resistance, with a special fragrance, and can prevent insects. , is famous for its excellent material and wide range of uses. It is a kind of Phoebe with high economic value, and it is also a famous garden ornamental and urban greening tree species. Due to the logging and utilization in the past dynasties and the serious damage of diseases and insect pests, the population number has been successively reduced, and the species have been declining one after another. It has been listed as a second-class protected endangered species. Cultivating strong seedlings is the basis...
