specific example

[0021] The present embodiment is a concrete example of the method for cultivating strong seedlings of the seedlings of Sansanthoxylum bungeanum container seedlings of the present invention, comprising the steps of:

[0022] (1) Seed pre-treatment: On August 20, 2017, the mature sansanthoxylum fruit was collected in the suburbs of Nanning, Guangxi, soaked in water for 3 hours, mixed with fine sand, rubbed off the peel and pulp, and then rinsed with water. Dry the clean seeds in a cool place, select full and high-quality seeds as sowing materials, and store them in a fresh-keeping cabinet at 4°C until use.

[0023] (2) Buried seeds in sand to accelerate germination: Sansanthoxylum seeds were sterilized with 1000 times chlorothalonil solution for 5 minutes, washed with water, dried for later use, and accelerated germination was performed on a sand bed in a plastic greenhouse. Irrigate the sand bed with 0.1% potassium permanganate solution 3-5 times, and after disinfection for 1 d...

Embodiment 2

[0033] This example is another example of the method for cultivating strong seedlings of Sansanthoxylum chinensis container seedlings according to the present invention, mainly to investigate the promotion effect of salicylic acid solution treatment on seedling growth.

[0034] (1) After 7 months of sowing and raising seedlings, that is, in March of the second year, select the seedlings of Sansanthoxylum bungeanum container seedlings that are basically the same in growth, the size of the seedling bag is 12cm * 14cm, and the matrix composition and mass ratio in the described seedling bag are: coconut bran : peat soil: perlite = 7: 2: 1, the seedling cultivation greenhouse is a shading net with a covering height of 2m and a shading degree of 30%-40%.

[0035] (2) Adopt 4 concentrations of salicylic acid, respectively 50mg / L, 100mg / L, 150mg / L, 200mg / L, set no addition of salicylic acid as the control (CK), a total of 9 treatments, each treatment 3 Repeatedly, each replicated 5 se...

Abstract

A method for cultivating strong seedlings of sansanthoxylum container seedlings, comprising the following steps: after collecting sansanthoxylum seeds in July-August of that year, soaking the seeds with clear water, mixing and kneading them with river sand, rinsing them with clear water, drying them, and placing them on a sand bed The seeds are buried in sand to accelerate germination, and the thickness of the covering soil is 1-2cm; after 20 days of sowing, they are transplanted into 12cm×14cm black plastic seedling bags for cultivation, and the seedling substrate is coconut bran: peat soil: perlite = 7:2:1; The film and shading degree are 30% to 40% shading net. Beginning in March of the second year, a salicylic acid solution with a concentration of 150 mg / L was poured every 30 days, with an interval of 15 days from conventional fertilization; the salicylic acid was sprayed until the end of the seedling fast-growing period in October. The method of the present invention adopts the combination of sand burial for accelerating germination, light substrate seedling cultivation and salicylic acid spraying to cultivate Sansanthoxylum seedlings. The problem of slow growth can improve the emergence rate of strong seedlings, which can be applied to the production of Sansho pepper container seedlings.

Description

technical field [0001] The invention relates to a method for cultivating strong seedlings of Sansanthoxylurea seedlings, which is suitable for container seedling cultivation of the seedlings of the liana. Background technique [0002] Sanjiaozi is a climbing shrub belonging to the genus Ziyupan in the Annonaceae family. It has various potential values ​​in ornamental, edible, medicinal, soil consolidation and slope protection, etc. Sanjiaozi grows in dense forests or low-altitude shrubs in mountains and hills. At present, it is basically in a wild state, and large-scale artificial planting is rarely carried out. [0003] There are few studies on Sansanthoxylum at home and abroad, and there are some reports mainly focusing on geographical distribution, leaf morphology, chemical composition, fruit nutritional components, and photosynthetic characteristics; The seeds of Sansanthoxylum were cultured in vitro, and some rooted seedlings were obtained; Wang Xiuli et al. reported t...
