Embodiment 1

[0023] The pot experiment of embodiment 1, Leymus chinensis accelerator

[0024] This embodiment mainly includes four steps: (1) preparation of potted Leymus chinensis seedlings; (2) preparation of Leymus chinensis accelerator No. 1; (3) application of Leymus chinensis accelerator; (4) implementation of effect measurement.

[0025] (1) Preparation of potted Leymus chinensis seedlings: On April 1, 2015, at the Inner Mongolia Grassland Ecosystem Orientation Research Station of the Chinese Academy of Sciences (Xilinhot), the Leymus chinensis rhizome was excavated, and a tiller was selected with scissors. The rhizomes of the buds are 10cm (the rhizomes on both sides of the buds are 5cm), and they are planted in flowerpots (the diameter of the flowerpot is 28cm, and the height is 23cm). Each pot is pre-filled with 10 kg of soil. The soil is taken from the Leymus chinensis plot and passed through a 2mm sieve. The rhizomes are buried at a depth of 3 cm, and after the burial, water 50...

Embodiment 2

[0034] Embodiment 2, different Leymus chinensis accelerators promote natural grass land Leymus chinensis recovery experiment

[0035] (1) Preparation of Leymus chinensis accelerator and mixed fertilizer

[0036] Fully stir and mix 20kg urea, 3.0kg diammonium phosphate and 2.0g 0.01% 2,4-epibrassinolide soluble powder to prepare Leymus chinensis Accelerator No. 1.

[0037] Fully stir and mix 20kg urea, 4.0kg diammonium phosphate and 2.0g 0.01% 2,4-epibrassinolide soluble powder to prepare Leymus chinensis accelerator No. 2.

[0038] Fully stir and mix 20kg urea, 4.0kg diammonium phosphate and 4.0g 0.01% 2,4-epibrassinolide soluble powder to prepare Leymus chinensis accelerator No. 3.

[0039] Fully stir and mix 20kg urea and 4.0kg diammonium phosphate to make a mixed fertilizer.

[0040] (2) Effects of different Leymus chinensis accelerators on the restoration of Leymus chinensis in natural grassland

[0041] The experiment was carried out in 2016 at the natural grassland re...

Abstract

The invention discloses a leymus chinensis accelerant and an application thereof, and belongs to the technical field of biology. The leymus chinensis accelerant provided by the invention comprises nitrogen elements, phosphorus elements and brassinolide in the mass ratio of the nitrogen elements to the phosphorus elements to the brassinolide being 10000 to (1000-2500) to (0.0001-0.0003). The leymus chinensis accelerant is used for restoring degraded leymus chinensis grasslands. The leymus chinensis accelerant disclosed by the invention can quickly increase the proportion of leymus chinensis in community by promoting tiller differentiation of the leymus chinensis, so as to restore the degraded leymus chinensis grassland.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to an accelerator of Leymus chinensis and its application. Background technique [0002] Leymus chinensis (Leymus chinensis) is the highest quality gramineous forage grass in natural pastures in my country. Leymus chinensis used to be the highest quality grassland widely distributed in Inner Mongolia grassland and Northeast grassland in my country. In the 1950s and 1960s, my country's Leymus chinensis was once exported to Japan and South Korea in large quantities. In the past half a century, due to overgrazing or successive years of mowing, most Leymus chinensis grasslands have been seriously degraded, and the proportion of Leymus chinensis in the community has dropped from 50%-60% to less than 10%. How to restore the productivity of the degraded Leymus chinensis grassland, especially the proportion of high-quality pasture—Leymus chinensis in the community has become a major technical...
