Embodiment 1

[0013] Embodiment 1: indoor synergy test

[0014] Sun Yunpei method to calculate co-toxicity coefficient (CTC), co-toxicity coefficient (CTC) ≥ 120 means synergistic effect; co-toxicity coefficient (CTC) ≤ 80 means antagonism; 80 < co-toxicity coefficient (CTC) < 120 means relative add effect.

[0015] Actual toxicity index (ATI) = (standard drug EC50 / test drug EC50) × 100.

[0016] Theoretical toxicity index (TTI) = (toxicity index of A × percentage of A in the mixture) + (toxicity index of B × percentage of B in the mixture).

[0017] Co-toxicity coefficient (CTC) = [mixture measured toxicity index (ATI) / mixture theoretical toxicity index (TTI)] × 100

[0018] Dilute 95.4% oxyenadenine and 95.5% gibberellic acid to make a 1.6 μg / mL mother liquor with acetone and Tween-80 respectively, and use the mother liquor to prepare benzylaminopurine and gibberellic acid The mass ratio of acid is 1:10—10:1, and the specific data of the test results are shown in Table 1

Embodiment 2

[0022] Example 2: 4% benzylaminopurine gibberellic acid soluble formulation

[0023]

[0024]

Embodiment 3

[0025] Embodiment 3: Cucumber Yield Increase Efficacy Test

[0026] The test agent is 4% benzylaminopurine · gibberellic acid soluble solution, the test site is Nanning City, Guangxi, and the test time is June 2014. The cucumber field with better water and fertilizer is selected, and the method of mechanical spraying is used to spray 3% gibberellic acid. Mycolic acid emulsifiable concentrate (Shaanxi Meibang Pesticide Co., Ltd.) 750 times liquid was used as a control agent, and the above-mentioned 4% benzylaminopurine gibberellic acid soluble solution 200 g / mu was used for test treatment. The growth of cucumber was investigated 60 days after spraying, and the control effect of 60 days after spraying was calculated strictly according to the calculation method stipulated in the national standard of the People's Republic of China "Pesticide Efficacy Field Test Guidelines". The above 3% gibberellic acid EC and 4% benzylaminopurine · gibberellic acid soluble solution after 60d were...

Abstract

The invention relates to a plant growth regulator containing a leaf fertilizer. The plant growth regulator containing the leaf fertilizer comprises benayl aminopurine, gibberellic acid, leaf fertilizer, and an accessory ingredient, wherein the weight ratio between benayl aminopurine and gibberellic acid is 1:10 to 10:1; the weight percentage of the total weight of benayl aminopurine and gibberellic acid in the composition is 0.01% to 15%. The plant growth regulator containing the leaf fertilizer can be made into a solution in the actual use. It is tested by massive filed experiments that the plant growth regulator containing the leaf fertilizer has a good effect in accelerating the growth and increasing the output of crops such as the cucumber, the citrus and the red jujube.

Description

technical field [0001] The invention relates to a plant growth regulator containing foliar fertilizer, which comprises benzylaminopurine, gibberellic acid, foliar fertilizer and additives, and is suitable for promoting growth and increasing production of crops such as cucumbers, citrus and jujube. Background technique [0002] Benzylaminopurine belongs to the class of cytokinins, and plant endogenous hormones exist in plant seeds, roots, stems, leaves, young meristems and developing fruits. It is mainly secreted from the root tip and transmitted to other parts to stimulate cell division, promote the formation of chlorophyll, and prevent premature aging and fruit shedding. Promote photosynthesis and protein synthesis, promote flower bud differentiation and formation, and have a good preventive effect on tomato, cucumber, and tobacco virus diseases. [0003] The most significant physiological effect of gibberellic acid is to promote the growth of plants, which is mainly becau...
