Problems solved by technology

The low-altitude simulated cultivation conditions shortened the annual growth period of Fritillaria by one month, and the plant height and 100-grain weight of Fritillaria decreased, which seriously affected the yield of Fritillaria
Afterwards, the total alkaloid content of Fritillaria was measured, and it was found that the total alkaloid content of Fritillaria under low-altitude simulated cultivation conditions was also significantly lower than that under high-altitude semi-wild tending conditions, and the medicinal effect of Fritillaria could not be achieved if it seriously affected Pharmacopoeia standard
This phenomenon is more serious under domesticated cultivation conditions

Embodiment 1

[0024] Embodiment 1. Application of an inducer for promoting quality improvement and yield increase of plants to promote quality improvement and yield increase of Fritillaria

[0025] 1. Soil preparation and sowing

[0026] In October 2018, in Maxia Town, Huating City, at an altitude of 2,000 meters, 50% of the sunshade nets were set up to plant Gansu Fritillaria. Apply 800 kg of organic fertilizer per mu, dig 3-year-old Fritillaria fritillaria, select fritillaria bulbs of the same size, wash the surface soil with tap water, soak in 1000 times liquid carbendazim for 20 minutes, dry the surface water and sow, and sow for each treatment 500 grains, repeated 3 times, covered with pine needles after sowing, daily management.

[0027] Seedlings emerged at the end of March 2019, and the emergence rate reached more than 90% in early April.

[0028] 2. Inducer spraying

[0029] In the first ten days of April, spray the inducer on the foliage after the seedlings are aligned, once ev...

Embodiment 2

[0047] Example 2. Determination of Physiological and Biochemical Indexes of Fritillaria fritillariae leaves after treatment with inducer

[0048] The malondialdehyde content detection kit used in the detection of this embodiment, the chlorophyll content detection kit, the hydrogen peroxide content detection kit, the superoxide dismutase activity detection kit, the peroxidase activity detection kit and the peroxide Hydrogenase activity detection kits were purchased from Suzhou Keming Biotechnology Co., Ltd.

[0049] As a signal molecule, hydrogen peroxide can promote the growth of adventitious roots and the growth and expansion of underground parts of rhizome crops; there is a certain positive correlation between chlorophyll content and biomass; malondialdehyde is an important indicator of cell membrane damage; superoxide dismutation Enzyme, peroxidase, catalase is the main ROS scavenging system. All of the above are related indicators for evaluating the physiology and biochem...

Abstract

The invention relates to the technical field of biology, and in particular, relates to an inducer for promoting plant quality improvement and yield increase. The inducer comprises nano-iron and hydroxypropyl methyl cellulose, the content of the nano-iron in the inducer is 5-10 mg / L, and the medicinal plant is fritillaria; a use method of the inducer comprises the steps of spraying the nano-iron toleaf surfaces once every two weeks and spraying the nano-iron for four times in total. The inducer provided by the invention is easy to operate and high in practicability, the hundred-grain weight can be increased, the yield can be increased, more importantly, it can be guaranteed that the total alkaloid content of fritillaria is increased, and the quality is guaranteed.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to an inducer for improving plant quality and yield and application thereof. Background technique [0002] Gansu Fritillaria (F.przewalshii Maxim) is one of the medicinal plants of the precious medicinal material Chuan Fritillaria, mainly distributed in the alpine shrubs and grasses above 2800 meters above sea level in Minxian, Wudu, Zhouqu, Yuzhong and other places in Gansu Province , Cool and shade is the main feature of the climate in its distribution area. Gansu Fritillaria grows slowly, has harsh environmental requirements, low reproduction coefficient, and serious root rot, which has severely restricted the development of the artificial planting industry. At present, there are mainly two suitable modes for artificial field planting of fritillary fritillaria in Gansu: semi-wild tending and simulated cultivation. Semi-wild tending is concentrated planting in a natural environment ...
