Embodiment 1

[0025] The maize variety used in the experiment was Nongda 108. There were two treatments in the experiment, the control group and the experimental group.

[0026] The composition of per liter of control group and experimental group soaking liquid is respectively:

[0027] Control group: 1g calcium chloride and 0.25g zinc sulfate, dissolve the two with an appropriate amount of water, and then dilute to 1L with water.

[0028] Experimental group: 1mg melatonin, 0.5mL ethanol, 10mg chitosan oligosaccharide, 10mg potassium chloride, and the rest is water.

[0029] Select corn seeds with plump and uniform grains, soak the seeds in the seed soaking solution of the above-mentioned control group and experimental group respectively, and soak for 16 hours at 25°C under dark conditions to allow the seeds to fully contact with the soaking solution. After soaking the seeds, the seeds were placed in pre-prepared petri dishes (petri dishes with a diameter of 12 cm equipped with double-lay...

Embodiment 2

[0032] The same materials and procedures as in Example 1 were followed, only the composition of the experimental groups was different. The composition of the seed soaking solution per liter of the experimental group was: 2mg melatonin, 0.5mL ethanol, 10mg chitosan oligosaccharide, 10mg potassium chloride, and the rest was water.

[0033] According to statistical analysis, the seed germination rate of the experimental group was 70.8%, which was 1.7 times that of the control group.

Embodiment 3

[0035] The same materials and procedures as in Example 1 were followed, only the composition of the experimental groups was different. The soaking solution of each liter of the experimental group consisted of: 5 mg melatonin, 0.5 mL ethanol, 10 mg chitosan oligosaccharide, 10 mg potassium chloride, and the rest was water.

[0036] According to statistical analysis, the seed germination rate of the experimental group was 66.7%, which was 1.6 times that of the control group.

Abstract

The invention discloses salt-resistive seed soaking liquid of corn. The seed soaking liquid per litre comprises the following ingredients: 1-10mg melatonin, 10-50mg chitosan oligosaccharide, 9-11mg potassium chloride, 0.4-0.6mL alcohol and the balance of water. Before seeding, corn seeds are soaked in the salt-resistive seed soaking liquid of the corn, the salt-resistive seed soaking liquid can effectively solve the key technical problem of a low corn seed germination rate under a salt stress condition during current corn production, and technical guarantee is provided for the corn production in a salty area.

Description

technical field [0001] The invention belongs to the field of crop seed soaking agents, and in particular relates to a salt-tolerant corn seed soaking liquid and a preparation method thereof. Background technique [0002] Soil salinization is one of the main limiting factors in modern agricultural production. Over 900 million hectares of soil worldwide are affected by salinization 2 , accounting for more than 6% of the global land area, and 200 million hm of arable land affected by salinization 2 , accounting for 13% of the global arable land area, while the global 240 million hm 2 About 50% of the irrigated land is salinized. Corn is one of the three major food crops in the world, and it is also an important feed and industrial raw material. However, the salt tolerance of corn is low, and its limit salinity is 1.7dsm -1 (l dsm -1 =10mM NaCl) per l dsm above the limit salinity -1 , the yield is reduced by 12%. High and stable corn yields are related to national food s...
