Embodiment 1

[0051] A cultivation method for improving stress resistance of wheat, comprising the following steps:

[0052] S101, soak wheat seeds in 0.05 (mol / L) sodium ethane methanesulfonate solution for 1.5 hours, treat with 2.4 g / L solution for 10 hours, rinse and take out to dry.

[0053] S102, placing the above-mentioned seeds in a growth regulator, and continuing to soak at 24-30° C. for 20-30 hours.

[0054] S103, placing the seeds obtained in step S102 in the substrate, and cultivating them until they germinate.

[0055] S104, transplanting the germinated wheat seedlings into nutrient soil, continuing to cultivate them at -1-1°C for 5-10 days, and then cultivating them until they mature according to conventional methods.

[0056] A kind of cultivation method of improving wheat stress resistance of embodiment 2-18, referring to embodiment 1, difference sees table 1 below:

[0057] Table 1 Parameter Report of a Cultivation Method for Improving Stress Resistance of Wheat in Exampl...

experiment example 1

[0063] In combination with Examples 1, 9 and 18, the above-mentioned wheat stress resistance cultivation method and comparative examples 1 and 2: conventional wheat planting methods were tested for verification.

[0064] Test base: test field in Yaodu District, Linfen City, Shanxi Province

[0065] In early October 2018, the experimental field was divided into 5 plots, and each plot harvested 10m 2 , There is an interval between two adjacent blocks to avoid mutual influence. Water and fertilize regularly to ensure normal growth.

[0066] In December of that year, the wheat was sprayed with glyphosate, and the state of the plants after spraying was recorded. Test medicament is 41% glyphosate water agent (production of U.S. Monsanto Company Beijing agency), as shown in table 2, figure 2 It is a schematic diagram of the wheat drug resistance test results of a cultivation method for improving the stress resistance of wheat in the embodiment of the present invention, referring ...

experiment example 2

[0069] In combination with Experimental Example 1, the germination of wheat seeds induced by different concentrations of sodium ethanemethylsulfonate in Examples 7-12 was investigated.

[0070] Test base: test field in Yaodu District, Linfen City, Shanxi Province

[0071] In early October 2018, the experimental field was divided into 6 plots, and each plot harvested 10m 2 , There is an interval between two adjacent blocks to avoid mutual influence. Water and fertilize regularly to ensure normal growth.

[0072] In December of that year, the wheat was sprayed with glyphosate, and the state of the plants after spraying was recorded. Test medicament is 41% glyphosate water (produced by U.S. Monsanto company Beijing agency), as table 3, the survival situation contrast of wheat spraying different concentration glyphosate plants, as can be seen, wheat stress resistance of the present invention When the cultivation method of sodium ethanesulfonate is treated at a concentration of ...

Abstract

The invention discloses a cultivation method for improving the stress resistance of wheat, which comprises the following steps: S101, soaking wheat seeds in a sodium ethanemethanesulfonate solution with the concentration of 0.05-0.5 (mol / L), treating with a glyphosate solution with the concentration of 2.4-3.2 (g / L), washing, taking out, and airing; S102, placing the aired seeds in a growth regulator, and continuously soaking the seeds at 24-30 DEG C for 20-30 hours; S103, placing the seeds obtained in the step S102 in a matrix to be cultured until germination; and S104, transplanting the germinated wheat seedlings into nutrient soil, continuously culturing for 5-10 days at the temperature of -1-1 DEG C, and culturing according to a conventional method until the germinated wheat seedlingsare mature. According to the method disclosed by the invention, the seeds have certain cold resistance, so that a wheat plant with stress resistance is obtained.

Description

technical field [0001] The invention relates to agricultural planting, in particular to a cultivation method for improving stress resistance of wheat. Background technique [0002] At present, wheat is a crop of the genus Triticum in the Gramineae family. It is one of the earliest cultivated crops in the world. After long-term development, it has become the food crop with the widest distribution, the largest area, the highest total output, the largest trade volume, and the highest nutritional value in the world. one. According to the sowing period, it is divided into two types: winter wheat and spring wheat. my country is dominated by winter wheat. [0003] The breeding technology of improved varieties is an important link to ensure that the quality and yield of wheat seeds meet the requirements, but the wheat obtained by existing methods has poor resistance to pesticides and insect pests. Contents of the invention [0004] The present invention is aimed at above-mentio...
