Problems solved by technology

However, this method has the following disadvantages: the flowering period is changed through genetic improvement, and there is little difference in flowering time among different materials of the same species. It is necessary to select special materials with significantly longer flowering periods to breed varieties with long flowering periods. Screening for genetic improvement takes a long time, with large initial investment and high cost
However, this method has the following disadvantages: it has little influence on the flowering period of rapeseed, and is not suitable for prolonging the flowering period of rapeseed
However, this method has the following disadvantages: it only has a more obvious effect on the flowers grown in the greenhouse, and it is not suitable for rapeseed grown in large areas.
[0008] (4) Combining pruning to delay flowering
This method has the following disadvantages: it is not suitable for large-scale cultivation of rapeseed

Embodiment 1

[0049] This embodiment provides a medicament for prolonging the flowering period of ornamental rapeseed. The medicament includes ethanol, water and indole acetic acid, wherein the concentration of indole acetic acid is 200 mg / L, and the volume ratio of ethanol to indole acetic acid is 1:3.

[0050] The preparation method of this medicine is as follows:

[0051] First, add indole acetic acid into ethanol, and then stir and mix to fully dissolve the indole acetic acid to obtain an ethanol solution for later use. Secondly, the ethanol solution is added into water, and the ethanol solution is mixed with water by rapid stirring to obtain the medicament.

Embodiment 2

[0053] This embodiment provides a medicament for prolonging the flowering period of ornamental rapeseed. The medicament includes ethanol, water and indole acetic acid, wherein the concentration of indole acetic acid is 125 mg / L, and the volume ratio of ethanol to indole acetic acid is 1:3.

[0054] The preparation method of this medicine is as follows:

[0055] First, add indole acetic acid into ethanol, and then stir and mix to fully dissolve the indole acetic acid to obtain an ethanol solution for later use. Secondly, the ethanol solution is added into water, and the ethanol solution is mixed with water by rapid stirring to obtain the medicament.

Embodiment 3

[0057] This embodiment provides a medicament for prolonging the flowering period of ornamental rapeseed. The medicament includes ethanol, water and indole acetic acid, wherein the concentration of indole acetic acid is 438 mg / L, and the volume ratio of ethanol to indole acetic acid is 1:4.

[0058] The preparation method of this medicine is as follows:

[0059] First, add indole acetic acid into ethanol, and then stir and mix to fully dissolve the indole acetic acid to obtain an ethanol solution for later use. Secondly, the ethanol solution is added into water, and the ethanol solution is mixed with water by rapid stirring to obtain the medicament.

Abstract

The invention provides a method and an agent for prolonging the flowering stage of ornamental type rape flowers as well as an agent preparing method, and belongs to the field of crop cultivation. The agent is a solution prepared from indole-3-acetic acid and a solvent through mixing, wherein the concentration of indole-3-acetic acid is 100-600 mg / L. The aqueous agent has the advantages of safe use and non-toxic, and absorption of indole-3-acetic acid in the agent by rape is facilitated. Indole-3-acetic acid with the concentration of 100-600 mg / L has an inhibiting function on the growth speed of the rape flowers, so that the flowering stage of the rape flowers is prolonged, and the ornamental flowering stage is prolonged.

Description

technical field [0001] The invention relates to the field of crop cultivation, in particular to a method for prolonging the flowering period of ornamental rapeseed, a medicament and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, leisure and sightseeing has become one of the main ways for people to relax and relieve stress. Rapeseed has the advantages of simple planting management, easy scale formation, obvious shocking effect, and full bloom in early spring. Sightseeing agriculture featuring rapeseed flowers has developed rapidly in recent years. Wuyuan in Jiangxi, Luoping in Yunnan, and Xinghua in Yangzhou are all good places to watch rapeseed flowers. The ornamental rape flower industry has driven the rapid development of the local economy. Take Wuyuan, Jiangxi Province, which is known as the most beautiful village in China, as an example. The comprehensive economy of its sightseeing rapeseed is about 1 bill...
