Embodiment 1

[0022] Embodiment 1 prepares plant growth promoter

[0023] Collect the aerial parts of German chamomile, herb and tansy, dry them in the shade indoors, cut them into 2-3cm pieces, and crush them into powder for later use.

[0024] Mix the powders of German chamomile, vanilla and tansy in a ratio of 1:1:1 by weight, put them in water for extraction at a ratio of 1:20 by weight, leave to soak at 25°C for 24 hours, and filter with gauze for 2 Second, the filtrate is the plant growth promoter of the present invention.

Embodiment 2

[0025] Embodiment 2 prepares plant growth promoting agent

[0026] Collect the aerial parts of German chamomile, herb and tansy, dry them in the shade indoors, cut them into 2-3cm pieces, and crush them into powder for later use.

[0027] Mix the powders of German chamomile, vanilla and tansy in a ratio of 1:2:1 by weight, put them in water for extraction at a ratio of 1:10 by weight, leave to soak at 25°C for 24 hours, and filter with gauze for 2 Second, the filtrate is the plant growth promoter of the present invention.

Embodiment 3

[0028] Embodiment 3 prepares plant growth promoting agent

[0029] Collect the aerial parts of German chamomile, herb and tansy, dry them in the shade indoors, cut them into 2-3cm pieces, and crush them into powder for later use.

[0030] Mix the powders of German chamomile, vanilla and tansy at a ratio of 1:2:3 by weight, place them in water for extraction at a ratio of 1:30 by weight, leave to soak at 25°C for 24 hours, and filter with gauze for 2 Second, the filtrate is the plant growth promoter of the present invention.

Abstract

The invention provides a plant growth promoting agent. The plant growth promoting agent comprises water extracts of dry powder of overgroundparts of German chamomile, hyssopus officinalis and tanacetum vulgare L. After the plant growth promoting agent is applied to leaf vegetables of pakchoi, oilseed rape, lettuce and the like, during harvesting, compared with plants which are not applied with theplant growth promoting agent, the height of the leaf vegetables which are applied with the plant growth promoting agent increases by 41.5%, the number of leaves 24%, the dry weight of the overgroundparts 75.2%, and the overall weight 70.4%. Compared with plants which are applied with fertilizers normally, the leaf vegetables applied with the plant growth promoting agent have a similar growth effect, but the plant growth promoting agent has a larger ecological significance. In practical production, the plant growth promoting agent can replace normal fertilizers, accordingly the application ofnitrogen is reduced, and the problem is relieved that currently a nitrogenous fertilizer is applied in soil excessively thus the nitrogenous fertilizer is residual.

Description

technical field [0001] The invention belongs to the field of plant allelopathy, and in particular relates to a plant growth promoter. Background technique [0002] The term allelopathy was first proposed by Austrian scientist Molisch H in 1937. The 1st World Congress of the International Allelopathy Society (IAS) was held in Spain in 1996, and the 6th Congress was held in China in 2011. Plant allelopathy is the release of chemical substances from plants to the environment through leaching, volatilization, residue decomposition, and root secretion, thereby producing direct or indirect, harmful or beneficial effects on surrounding plants. Allelopathy is mainly manifested in affecting cell division, elongation and the fine structure of root tips, affecting the permeability of cell membranes, affecting the absorption of mineral ions, affecting photosynthesis, respiration, etc. Now the research on allelopathic effects at home and abroad has separated and identified some alleloch...
