High yields from foliar topdressing in green beans: mastering the method is key

Green beans (snap beans) are a legume crop that flowers and sets pods continuously, with a high demand for nutrients. If nutrient supply is insufficient, flowering and pod setting will occur at intervals and pods will be deformed, while the harvest period is shortened, yields are low, and quality is poor. As for the nutrients green beans need for flowering and pod setting, besides being taken up and supplied by the root system, foliar absorption is faster and more effective.

If, during the flowering and pod-setting period of green beans, you spray the foliage once every 7 to 10 days with a mixture of 0.1% magnesium sulfate, 0.2% urea, 0.3% monopotassium phosphate, 600-fold nucleotide active liquid fertilizer, 1000-fold natural brassin, and 1500-fold Qinongsu chelated fertilizer, evenly wetting all stems and leaves, flower buds, and pods, until water droplets just begin to drip down, then supplementing nutrients through the leaves can enable green beans to flower and set pods continuously, with good pollination, many pods, plump pods that are neither curved nor deformed, plants that do not age prematurely, and dark green leaves, clearly extending the harvest period, giving high yields and good quality.
