For the long peanuts, sprinkle paclobutrazol 150ppm, can control its growth, is conducive to flowering, and promote fruit fullness. For general growth peanuts, spraying 0.5% borax and 50 g/mu molybdenum ammonium mixture can increase production by more than 15%. For peanuts with poor growth, spray potassium dihydrogen phosphate plus 1% urea mixture for 1--2 times, and the results are good.
