Problems solved by technology

[0005] To sum up, although there are currently some technical solutions that can partially solve the problem of corn germination difficulties under drought conditions, there are problems such as complex operation procedures, high treatment costs, poor effects, high environmental requirements, and difficulties in subsequent seed treatment.
It can be seen that some current technical solutions only partially solve the germination problem of corn seeds under moderate drought conditions, and the problems of low germination rate of corn seeds, irregular emergence and slow growth of seedlings under relatively high drought conditions still need to be solved

Embodiment 1

[0027] The composition of the corn seed soaking solution in the test group was as follows: 0.23 mg melatonin, 0.5 mL ethanol, 0.13 mg L-aspartic acid, 10 mg potassium hydroxide and water to make up to 1 L. The corn seed soaking liquid of this test group is prepared according to the following steps: first dissolve 0.23mg melatonin with 0.5mL ethanol and mix, dissolve 0.13mg L-aspartic acid and 10mg potassium hydroxide with 100mL water and mix, Mix the above solutions and dilute to 1L with an appropriate amount of water, and stir well to obtain the soaking solution of the test group.

[0028] Select corn seeds with plump and uniform grains, soak the seeds in the above-mentioned seed soaking solution of the control group and the test group respectively, and soak for 16 hours in the dark at 25°C to allow the seeds to fully contact with the soaking solution.

[0029] With the seeds soaked in the seed soaking solution in the control group and the test group respectively in pre-prepa...

Embodiment 2

[0032] The same materials and procedures as in Example 1 were followed, only the composition of the test group was modified.

[0033] The composition of the seed soaking solution of the test group was as follows: 2.3 mg melatonin, 0.5 mL ethanol, 0.13 mg L-aspartic acid, 10 mg potassium hydroxide and water.

[0034] The germination potential and germination rate of the seeds in the test group were 26.7% and 63% respectively, and the germination potential and germination rate were 2.2 times and 1.4 times that of the control group, respectively.

Embodiment 3

[0036] The same materials and procedures as in Example 1 were followed, only the composition of the test group was modified.

[0037]The composition of the seed soaking solution of the test group was as follows: 23 mg melatonin, 0.5 mL ethanol, 0.13 mg L-aspartic acid, 10 mg potassium hydroxide and water.

[0038] The germination potential and germination rate of the seeds in the test group were 25.9% and 63%, respectively, which were 2.2 times and 1.4 times that of the control group.

Abstract

The present invention discloses a drought-resistant maize soaking liquid. The soaking liquid per liter comprises the following components: 0.23-23mg of melatonin, 0.13-13mg of L-aspartic acid, 9-11mg of potassium hydroxide, 0.4-0.6ml of ethanol and the balance of water. The maize seeds are soaked by using the drought-resistant maize soaking liquid disclosed by the invention before seeding, so that the problem that the maize seed germination rate is low under the drought condition in current maize production is effectively solved. The drought-resistant maize soaking liquid disclosed by the present invention has is reasonable in formula, simple in process, low in investment and good in effect.

Description

technical field [0001] The invention belongs to the field of crop seed soaking agents, and in particular relates to a corn drought-resistant seed soaking liquid and a preparation method thereof. Background technique [0002] Drought is the main factor limiting plant growth and crop yield, and it is also an important constraint factor for the development of agriculture and society in the world. Corn is one of the three major food crops in the world, and it is also an important feed and industrial raw material. It plays a pivotal role in global food security and economic development. The 2014 China Statistical Yearbook report pointed out that corn is the grain crop with the largest sown area and the highest total output in my country. At present, my country's corn planting area has reached 36 million hectares 2 , but more than half of them are planted in dry lands that mainly rely on natural precipitation, such as northwest, southwest, north and northeast regions. The annua...
