Problems solved by technology

[0003] The inflorescence of Cistanche is an infinite inflorescence, and the seed maturity at the top of the inflorescence is low, and the poor quality of the seeds is a practical problem encountered in the production of Cistanche seeds, and it is a problem that plagues the reproduction and expansion of Cistanche.
In recent years, although there is a new technology for the production of Cistanche seeds: the "foliar fertilizer method" invented by Liu Xin et al. (Patent Publication No. CN101336591), which solves the need for micro-fertilizers in the process of seed formation, the problem of nutrient shortage that limits seed formation has not yet been developed. Solved, the problem of uneven seed quality still exists

Embodiment 1

[0020] From May to July 2010, in Dengkou County, Bayannaoer City, Inner Mongolia, Inner Mongolia Wangyedi Cistanche Biological Co., Ltd. Jiazitan Haloxylon-Cistanche base through topping to improve the yield and quality of Cistanche seeds, the specific method is as follows:

[0021] (1) Selection of reserved inflorescences of Cistanche deserticola: select the reserved seeds of Cistanche deserticola with a length of inflorescence greater than 30 cm.

[0022] (2) Topping the inflorescence of Cistanche deserticola: Remove the top 3cm-5cm of the inflorescence of Cistanche deserticola at the initial flowering stage (30% of the flowers in the inflorescence are fully open).

[0023] (3) Sterilization and bagging of inflorescences: immediately after topping the inflorescences of Cistanche deserticola, 1000 times of liquid with a mass fraction of 0.05% carbendazim was used to spray the wound for sterilization, and then the inflorescences were covered with nylon mesh bags under natural c...

Abstract

The invention discloses a method for increasing broomrape seed yield and quality by top pruning, belonging to the technical field of agricultural plant culture. The method comprises the steps of: selecting broomrape inflorescences with length more than 30cm to reserve seeds for planting at the primary florescence of broomrape, removing 3-5cm at the tops of the broomrape inflorescences, spraying 1000 times of 0.05wt% carbendazol at the top pruning positions for sterilizing treatment, then covering the inflorescences with nylon net bags, growing in natural conditions, picking after 45-50d when broomrape capsules crack and seeds are ripe, screening and grading the broomrape seeds, and storing for seeding. By adopting the method, the difficulties of low top seed ripe degree and poor seed quality caused by growth habit of broomrape indeterminate inflorescences are overcome.

Description

technical field [0001] The invention belongs to the technical field of agricultural crop cultivation, and in particular relates to a method for improving the yield and quality of cistanche seeds by topping. Background technique [0002] Cistanche deserticola, a root parasitic plant of Liedanaceae, is a well-known tonic medicinal material, and its hosts are Haloxylon and Haloxylon albicans of Chenopodiaceae. In recent years, with the in-depth pharmacological research of Cistanche, the promotion of Cistanche products and the enhancement of people's awareness of health care, the demand for Cistanche has been increasing, resulting in the extreme shortage of wild resources of Cistanche, the contradiction between supply and demand in the market has become increasingly acute, and the market price has continued to rise. It has soared from 10-12 yuan / kg in 2000 to 220-240 yuan / kg in 2011. [0003] The inflorescences of Cistanche deserticola are infinite inflorescences, and the matur...
