Embodiment 1
[0057] Embodiment 1: a kind of preparation method for the anti-low temperature preparation of cotton production:
[0058] Preparation steps of preparation I:
[0059] (1) Weigh 65g of potassium dihydrogen phosphate, 60g of urea, 0.3g of manganese sulfate, 0.1g of zinc sulfate, 20g of boric acid, 4g of sodium salicylate, 20g of chitosan, 100g of potassium fulvic acid and 2.0g of sodium selenite , dissolved in 300m1 water to make solution A;
[0060] (2) Take by weighing 30g of glucose, 10g of ethylene glycol and 20g of calcium chloride, dissolve in 300ml of water, and make solution B;
[0061] (3) Mix solution A and solution B to obtain a mixed solution, add 20 g of Tween 60 to the mixed solution, stir evenly, and dilute to 1000 ml with water to obtain preparation I.
[0062] How to use Preparation I:
[0063] In April at the seedling stage of cotton growth, before the low temperature comes or when the low temperature has come, the stock solution of the preparation I is dilu...
