Embodiment 1

[0016] 1. Take auxin 1.5g, ethylene 1.5g, gibberellin 1.5g, indole acetic acid 2.0g, 6-benzylaminoadenine 1.5g, glycolic acid 30g, polyacrylamide 30g, Tween 80 27g, sulfuric acid Manganese 5g, water;

[0017] 2. Weigh manganese sulfate and dissolve it in 80°C proportioning water, then add the remaining raw materials according to the proportioning ratio, stir evenly, and let stand for 1 hour;

[0018] 3. At room temperature, mix the above two groups of solutions and stir evenly to obtain a growth regulator in the critical period of crop water demand according to the present invention.

Embodiment 2

[0020] 1. Take auxin 1.3g, ethylene 1.7g, gibberellin 1.3g, indole acetic acid 2.2g, 6-benzylaminoadenine 1.5g, glycolic acid 30g, polyacrylamide 30g, Tween 80 27g, sulfuric acid Manganese 5g, water;

[0021] 2. Weigh manganese sulfate and dissolve it in 80°C proportioning water, then add the remaining raw materials according to the proportioning ratio, stir evenly, and let stand for 1 hour;

[0022] 3. At room temperature, mix the above two groups of solutions and stir evenly to obtain a growth regulator in the critical period of crop water demand according to the present invention.

Embodiment 3

[0024] 1. There are 3 treatments in the experiment:

[0025] A growth regulator for crops in the critical period of water demand according to the present invention: use the paper tube seedling cultivation method to raise seedlings, and spray the compound growth regulator for crops at the seedling stage when the first pair of true leaves of the seedlings are unfolded. Increase production and increase sugar Seedling stage compound growth regulator uniformly mixed solution mixed with 100 times of water and sprayed on the leaves of crops with a sprayer, spraying 1 paper tube seedbed per kilogram; spraying for the second time the day before transplanting seedlings , the second spraying amount is the same as the previous spraying.

[0026] Commercially available crop seedling strengthening agent: 6.5g per bag of medicine is dissolved in 0.5kg of warm water, then add water until the solution weighs 4kg, stir evenly and pour it into 4 volumes of paper tube seedbeds when the true l...

Abstract

The invention discloses a crop water-need critical-period growth regulating agent, relates to crop growth regulating agents, and belongs to the technical field of crop planting. The crop water-need critical-period growth regulating agent is characterized by being composed of, by weight, 1.3-1.7% of auxin, 1.5-2.5% of ethylene, 1.3-1.7% of gibberellin, 1.8-2.2% of 6-benzylaminopurine, 25-35% of glycolic acid, 20-50% of polyacrylamide, 10-30% of polysorbate 80, 5.0-8.0% of manganese sulfate and the balance water. The crop water-need critical-period growth regulating agent has the advantages that the composite regulating agent is composed of plant hormones and element material required by living things, is particularly suitable for being used for salt, alkali and drought environmental conditions, can induce expression of crop stress resistance genes, and facilitates coordination and unification between crop and the environment, between individuals and colonies, between roots and overground parts, and between plant external forms and internal physiological functions.

Description

technical field [0001] The invention relates to a crop growth regulator, which belongs to the technical field of crop planting, in particular to a crop growth regulator in the critical period of water demand. Background technique [0002] The water requirement of crops varies continuously with the growth process throughout their life, and also fluctuates with meteorological conditions. Different growth stages have different sensitivity to water. Sensitivity to water, that is, the period when lack or excess of water has the greatest impact on yield is called the critical water period of crops. The amount of water required and the degree of sensitivity are different concepts, so the critical period is not necessarily the period when crops need the most water, nor is it necessarily the critical period of water demand. In the critical period of crop moisture, if the precipitation is appropriate and the guarantee rate is high, it is not the period that has the greatest impact o...
