Embodiment Construction

[0006] 1. Selection and processing of propagation material

[0007] Choose robust, no pest and disease Prunus polyphylla as the propagation material, cut into small sections according to 1-3 stem nodes of the tubers of Prunus polyphylla, and then cut each small section into small pieces longitudinally to ensure that each cut piece has stem marks, The incision is smooth, the size is basically the same, and the weight of each cut is 0.2-0.5 grams. In order to shorten the germination time of latent buds, increase the germination rate, and make the germination time consistent, the cut pieces can be aired for 1 day.

[0008] 2. Seedling management

[0009] Spread the humus soil or sandy soil treated with insecticides in the seedling bed, place the cut pieces in the seedling bed at a density of 4000-5000 pieces per square meter, and cover the 3-5cm after the cut pieces are placed. Humus soil or sandy soil, keep the relative humidity of the soil at 50-60%. After the cut pieces grow...

Abstract

The invention provides a multiple propagation cutting seedling raising method for a stem tuber of paris polyphylla var. yunnanensis. The method is characterized by the following steps: cutting transversely a strong disease-free stem tuber of paris polyphylla var. yunnanensis into small segments according to stripe, cutting each segment into small blocks which have a stem scar, placing the cut blocks on a seedling bed spread with humus soil and sandy soil, covering the cut blocks with 3 to 5 centimeters of humus soil and sandy soil, keeping a 60 to 70 percent relative humidity of the soil, shading the cut blocks according to a 40 to 60 shading degree, temporary planting the cut blocks for one year and then transplanting seedlings of the paris polyphylla var. yunnanensis. With the method, the germination percentage of the stem tuber of the paris polyphylla var. yunnanensis reach 85 to 90 percent and the rooting rate of the stem tuber of the paris polyphylla var. yunnanensis is 40 to 50 percent. Propagation coefficient of the stem tuber of the paris polyphylla var. yunnanensis of the method is increased by more than 5 times than that of the prior rhizome segment seedling raising method of paris polyphylla var. yunnanensis.

Description

technical field [0001] The invention relates to a method for raising seedlings of Chonglou dianthus tubers. Background technique [0002] Dianzhonglou (Paris polyphylla var.yunnanensis (Fr.) Hand.-Muzz), also known as: Chonglou, Aescin, Striga, etc., is a perennial herbaceous plant belonging to the Liliaceae Polyphylla, and is an important It is also the main raw material of various medicines. Due to long-term excessive excavation, the wild paronychia is decreasing year by year, and even facing depletion. In recent years, a variety of artificial propagation experiments have been carried out for cutting seedlings of Prunus yunnanensis. Although the cutting propagation of rhizomes is simple and the seedling cycle is short, the reproduction coefficient is small, and the problem of reproduction coefficient cannot be effectively solved. Disclosed a kind of cut off seedling raising method of Rhizome of Rhizome of Rhizoma yunnanensis as Chinese Patent Application No. 200710066296...
