Embodiment 1

[0073] Example 1, the influence of the composition composed of stachydrine and trigonelline on the inoculation effect of No. 1 alfalfa seed rhizobium seed coating agent

[0074] 1. Using a composition composed of stachydrine and trigonelline to prepare Zhongmi No. 1 alfalfa seed rhizobia seed coating agent and ball-coated alfalfa seed

[0075] No. 1 alfalfa seed rhizobia seed coating agent, composed of rhizobia agent, sodium carboxymethylcellulose as adhesive, bentonite and skim milk as substrate, rhizobia agent, adhesive, substrate and skim milk Each of the four components is individually packaged. In Zhongmi No. 1 alfalfa seed rhizobia seed coating agent, the mass ratio of rhizobia agent, adhesive, substrate and skim milk satisfies 100:1.6:300:0.02. The rhizobia agent is prepared by mixing the rhizobia culture (hereinafter referred to as the rhizobia culture) used to improve the yield and / or quality of alfalfa and the molybdenum-containing rhizobia adsorbent. Each 532.505g...

Abstract

The invention discloses a combination increasing the yield of alfalfa and improving the quality of alfalfa and application thereof. The combination used for preparing rhizobia culture media is composed of active components of components A and components B, the components A are prepared from stachydrine or hydrochloride of stachydrine, and the components B are prepared from trigonelline or hydrochloride of trigonelline. Alfalfa seed rhizobia seed coatings prepared from the combination used for preparing the rhizobia culture media increase the yield of medicago sativa L.cv.Zhongmu No.1 and improve the quality of the medicago sativa L.cv.Zhongmu No.1. Raw materials of the rhizobia seed coatings for the medicago sativa L.cv.Zhongmu No.1 are easy to obtain, the coating mode is easy to operate, coated seeds are suitable for storage, transportation and sowing, and the coating mode can provide favorable infection time and space for rhizobia infection root system inoculation.

Description

technical field [0001] The invention relates to a composition for improving the yield and quality of alfalfa and its application in the field of biotechnology. Background technique [0002] Alfalfa (Medicagosativa L.) is warm-loving, cold-resistant, widely adaptable, rich in nutrients, high in protein, and good in palatability. It is the most widely distributed cultivated pasture in the world today. Alfalfa seeds are small and carry less nutrients. The seeds in the normal germination state have relatively weak resistance to unfavorable sowing conditions such as drought and cold. Therefore, before planting, the alfalfa seeds are generally treated with technology such as pill coating. [0003] Rhizobia are a class of Gram-negative aerobic bacteria that can live in symbiosis with legumes, form root nodules and fix nitrogen in the air to provide nutrients for plants. Inoculation of Rhizobium meliloti can promote the growth and nodulation and nitrogen fixation of alfalfa, there...
