test crop: pepper
period of medication: before flowering
test reagent: 4% gibberellic acid emulsifiable concentrate
test time: may 25, 2017
test site: yanzhuangdian, zhongmou county
tester: wang haiting, li lingtao
i. test purpose
the effect of 4% gibberellic acid emulsifiable oil on the growth of pepper at the beginning of flowering period was studied in this experiment, which provided practical basis for the popularization of nongda gibberellin series products.
ii. test materials
test reagent: 4% gibberellic acid ec provided by zhengzhou nongda biochemical products co., ltd.
applicating tools: 1.5kg spraying pot.
iii. test design
3.1 gradient of drug solution dosage
4% gibberellic acid ec: 20 ppm, 40 ppm;
contrast: spraying clean water
usage: spray evenly onto leaves and drip.
3.2 test design
two tested agents were sprayed 2 m2 at each concentration, repeated three times, and sprayed with clear water as control.
3.3 contents and methods of investigation
investigation content: plant height, transverse diameter
survey method: measure the height and transverse diameter of hot pepper, select 10 measured data for each treatment, and calculate the average value.

v. discussion and analysis
according to the experimental results, spraying 20-40 ppm of gibberellin solution before the beginning of flowering period of pepper is helpful to promote the growth of plant height and transverse diameter of pepper. with the rapid growth of transverse diameter, the number of flowers and fruits is increased. in addition, spraying gibberellin at the same time, because the growth of pepper is accelerated, it is recommended to use 30 ppm, and supplement nutritional elements in a timely and appropriate amount. test crop: pepper
