Problems solved by technology

[0014] The technical scheme adopted by the present invention to solve the technical problem is: take the normal growing P. pontica tuber as the female parent, artificially block the original growth point of the living P. growth point, so as to achieve the purpose of rapid and large-scale vegetative propagation of new plant bodies (provenance), and solve the problem of low seedling reproduction rate, slow emergence, and large consumption tuber problem

Embodiment 1

[0028] Rapid tillering and reproduction of living tubers of Parisia diangi, (1) Selection of the female parent of Parisia diangi: Choose a plant with good base conditions, more than 6 years of planting, a tuber weight of more than 100 grams, and vigorous plant growth as the female parent.

[0029] (2) Topdressing: On the basis of conventional management, starting from the vigorous growth period of the chrysanthemum in June, topdressing organic fertilizer rich in calcium, phosphorus, potassium, and nitrogen every 45 days, topdressing 3 times, at 150 per mu Fertilize 1 kg, keep the soil moisture at 65%, control the shading rate at 70%, store nutrients for the female parent, and accumulate nutrients for more germination and tillering reproduction in the coming year.

[0030] (3) Promoting growth point: Routine management at other times. In December, when the plants on the ground of the heavy building are poured and the new buds have not yet emerged, remove the covering soil to fin...

Embodiment 2

[0038] Rapid tillering and reproduction of living tubers of Huazhonglou, (1) Selection of female parent of Huazhonglou: Select Chonglou with good base conditions, more than 5 years of planting, tuber weight of more than 90 grams, and vigorous plant growth as the female parent.

[0039] (2) Topdressing: On the basis of conventional management, starting from the vigorous growth period of the chrysanthemum in June, topdressing organic fertilizers rich in calcium, phosphorus, potassium, and nitrogen every 45 days, topdressing 3 times, at 135 per mu Fertilize 1 kg, keep the soil moisture at 65%, control the shading rate at 75%, store nutrients for the female parent, and accumulate nutrients for multi-point germination, tillering and reproduction in the coming year.

[0040] (3) Growth-promoting growth point: In December, when the plants on the ground of the chrysalis are down, and the new buds have not yet emerged, remove the covering soil to find the terminal buds, cut off the orig...

Embodiment 3

[0047] Rapid tillering and reproduction of living tubers of Nanzhonglou, (1) Selection of female parent of Nanzhonglou: Choose Chonglou with good base conditions, planting for more than 4 years, tuber weight of more than 120 grams, and vigorous plant growth as the female parent.

[0048] (2) Topdressing: On the basis of conventional management, starting from the vigorous growth period of the chrysanthemum in June, topdressing organic fertilizer rich in calcium, phosphorus, potassium, and nitrogen every 45 days, topdressing 4 times, at 140 per mu Fertilize 1 kg, keep the soil moisture at 65%, control the shading rate at 70%, store nutrients for the female parent, and accumulate nutrients for more germination and tillering reproduction in the coming year.

[0049] (3) Promoting growth point: On the basis of conventional management, the seedlings of the plants on the ground of the heavy building will fall until December, and when the new buds have not yet emerged, remove the cover...

Abstract

The invention relates to a quick traditional Chinese medicinal material paris polyphylla propagation technology, in particular to quick living paris polyphylla tuber tillering and propagation technology. The technology solves the problems that in the prior art, the (seeds, slices and tissue culturing) seedling reproduction rate is low, the seedling emergence speed is low, and a great number of tubers are consumed. The quick living paris polyphylla tuber tillering and propagation technology mainly includes the following steps of (1) paris polyphylla female parent selection, (2) topdressing, (3) growing point priming, (4) terminal bud healing and transplant and (5) seedling emergence and transplant. According to the method, quick tillering and propagation are conducted on living paris polyphylla tubers, under the condition that the living tubers are not destroyed, and the living paris polyphylla tubers are promoted to generate multi-point germination by interdicting the original growing points of plants through a biological principle.

Description

technical field [0001] The invention relates to a method for rapid propagation of Chinese herbal medicine Pachyphytum chinensis, in particular to a method for rapid tillering propagation of living tubers of P. chinensis. Background technique [0002] Chonglou ( Paris polyphylla Smith var .yunnanensis (Franch.) Hand.-Mazz.) is a perennial herbaceous plant of the Trillium family Pachyphyllum genus, aliased with unipedal lotus, Pachyphytum chinensis, Caoheche, etc. One of the base plants of the traditional Chinese medicinal material Chonglou. Wild parsley is distributed in Yunnan, Sichuan, Guizhou and other provinces. The main production areas are central Yunnan, western Yunnan and northwestern Yunnan. It grows at an altitude of 1400-3100m, with an annual average temperature of 10-13 °C and an annual rainfall of 850 °C. ~1200mm cold and cool mountainous areas, mostly in evergreen broad-leaved forests, coniferous and broad-leaved mixed forests, damp places on hillsides and s...
