Embodiment 1

[0031] This embodiment provides an anti-low temperature inducer, which is based on a total weight of 1 kg and consists of the following components:

[0032] 0.4ml, that is, 0.42g earthworm active enzyme plant polypeptide liquid,

[0033] 95mg chitosan,

[0034] 6g urea,

[0035] 1.5g potassium dihydrogen phosphate,

[0036] 2 μg methyl jasmonate,

[0037] The balance is the weakly acidic solvent obtained after thinning with white vinegar.

[0038] The steps for preparing the anti-low temperature inducer are:

[0039] In the first step, add 0.4ml earthworm active enzyme plant polypeptide liquid, 8g urea, 4g potassium dihydrogen phosphate, and 2 μg methyl jasmonate to 800ml distilled water to fully dissolve it;

[0040] Second step, in the first mixed solution of gained in the first step, add the solution that has been dissolved by 20ml white vinegar and contain 100mg chitosan;

[0041] In the third step, water is added to the second mixed solution obtained in the second s...

Embodiment 2

[0049] This embodiment provides the second anti-low temperature inducer, which is based on a total weight of 1 kg and consists of the following components:

[0050] 0.5ml, that is, 0.52g earthworm active enzyme plant polypeptide liquid,

[0051] 105mg chitosan,

[0052] 7g urea,

[0053] 2.5g potassium dihydrogen phosphate,

[0054] 2.3 μg methyl jasmonate,

[0055] The remainder is the weakly acidic solvent obtained after white vinegar is thinned out, and nonionic surfactants such as Tween (Tween) can generally be added in the weakly acidic solvent, accounting for about 0.1% of the total weight percentage of the low temperature inducer. As a non-ionic surfactant, Tween has strong hydrophilicity and can be used as an oil-in-water (O / W) emulsifier to disperse other substances in the solution evenly. It can also be used as a solubilizer to increase the concentration of various drugs. The solubility in the solution enables the drug to play a better role, and at the same time,...

Embodiment 3

[0065] The present embodiment provides a kind of compound agent, and before it is sprayed to plant blade, the compound agent of the following components needs to be diluted to 1kg by water:

[0066] 0.4ml earthworm active enzyme plant polypeptide liquid,

[0067] 100mg chitosan dissolved in 20ml white vinegar,

[0068] 8g urea,

[0069] 2 g potassium dihydrogen phosphate,

[0070] 2.2 μg methyl jasmonate,

[0071] 1g of Tween.

[0072] Carry out following test for the protective effect of the anti-low temperature inducer obtained by dilution of above-mentioned compound agent to the low temperature stress environment of wheat:

Abstract

The invention provides a wheat low-temperature-resistant inducer product and a use method thereof. The efficient low-temperature-resistant inducer is prepared by compounding jasmonic acid methyl ester with earthworm active enzyme plant polypeptide liquid, urea, monopotassium phosphate and chitosan, and by spraying the low-temperature-resistant inducer on leaf surfaces, the chlorophyll synthesis of wheat leaves can be remarkably improved, and the damage of reactive oxygen free radicals and the like to plasma membranes is reduced; the activity of antioxidant enzymes and the accumulation of osmotic regulation substances are enhanced, so that the cold resistance of the plants is enhanced, and the damage of low-temperature stress to the wheat plants is relieved. The pH value of the low-temperature-resistant inducer provided by the invention is 5.5-6, and the low-temperature-resistant inducer can effectively reduce the pungent smell of a preparation and lower the requirements of the preparation on transportation and storage conditions.

Description

technical field [0001] The present application relates to the field of plant growth regulators, in particular to a wheat low temperature resistance inducer product and its use method. Background technique [0002] Although wheat is a cool-loving crop, when the temperature is lower than the low temperature it can withstand in different growth stages, it will cause low-temperature freezing injury. For example, cold waves often occur near the jointing stage of wheat, resulting in freezing of tissue cells during spikelet differentiation, hindering spikelet differentiation during the tetrad period, and the upper and lower spikelets of wheat ears are not firm, and wheat yield is reduced; freezing damage in late spring will cause wheat hollow, The white ears and spikelets were sterile; in addition, the frost damage caused damage to the new tillers at the base of the wheat stem, resulting in a double decrease in the number of spikes per unit area and the number of grains per spike, ...
