Peanut application of growth regulators has the effect of promoting early growth of seedlings, increasing fruit weight, early maturity and high yield. Currently, there are two main types of growth regulators: one is a growth promoter containing micro-fertilizers, hormones, and the like; the other is a growth inhibitor that controls growth and prevents lodging.
 First, growth promoter  1.ABT4 or ABT8 rooting powder with 0.05 grams of ABT  4 or ABT  8 root powder to dissolve alcohol (or high alcohol) 25 ml, add 1 kg of water with peanuts, It can also be combined with 20% carbendazim wettable powder 50g and 40% dimethoate emulsifiable concentrate 10ml for seed treatment. The average yield of pods is about 25 kg, an increase of about 10%.
 2. Huimanfeng Mu with 50 ml of Huimanfeng 50 kg of water, foliar spraying on the 6-leaf stage of peanut seedlings, spraying a second time after one week, can promote the rapid expansion of the population and increase the leaf area. In the 12-leaf period, the leaf area index reached 3.66, 0.76 higher than the control. In the maturity period, the number of effects per plant increased by 1 to 1.2 compared with the control, and the yield of pods increased by 25.0 to 29.3 kg, an increase of 11.1% to 12.1%.
 3. China Spray Shibao uses 5 ml per mu, and the usage is the same as Huifeng. In the 12-leaf stage examination, the leaf area index increased by 0.45 compared with the control, and the number of branches and the number of underground fruit needles increased by 0.4 and 0.9 respectively. During the maturity period, the number of effects per plant increased by 0.5 compared with the control, and the yield of pods increased by 19.4 to 23.1. Kilograms, an increase of 8.1% to 10.9%.
 4. Plant health supplements use 30 grams of plant phytobiotics for 40 to 50 kilograms of water per acre, and foliar application at the initial flowering stage, the lower needle stage and the pod-forming stage. During the maturity period, the weight of one hundred fruits increased by 8 to 10 grams, and the yield of pods increased by 15.7 to 22.5 kilograms, an increase of 6.5% to 11.6%.
 Second, the growth inhibitor  1. Paclobutrazol with 15% paclobutrazol wettable powder 50 grams of water 50 kg, evenly sprayed on the peanut plant height 33 ~ 35 cm, leaf age 13 ~ 14 leaves, if 6 hours after application In case of heavy rain, it must be re-sprayed once. After 3 days, the leaf color was deepened, the leaves were thickened, and the stems were no longer elongated within 20 days, and the plants were strong and pierced. In the later examination, the lodging area was reduced by 70% compared with the control, and the maturity period was 3 to 5 days earlier. The number of effects per plant increased by 0.8, the weight of the fruit increased by 10 grams, and the yield of the pod increased by 34.0 kg, an increase of 14.8%.
 2. Uniconazole with 5% Uniconazole wettable powder 30g, the same as the use of paclobutrazol, after use can increase the yield of 33.3 kg of pods, an increase of 14.5%.
 First, growth promoter  1.ABT4 or ABT8 rooting powder with 0.05 grams of ABT  4 or ABT  8 root powder to dissolve alcohol (or high alcohol) 25 ml, add 1 kg of water with peanuts, It can also be combined with 20% carbendazim wettable powder 50g and 40% dimethoate emulsifiable concentrate 10ml for seed treatment.
