It is very important to fertilize potassium in melon beans.
Melon and bean crops such as cucumber, loofah, pepper, green beans, etc. are all typical potassium-potassic crops. Increasing potassium fertilizer plays an important role in improving yield and improving quality. In addition, the proportion of calcium absorbed by melons is relatively large, so the application of calcium fertilizer on the foliar surface has a certain yield increase effect. Through the visit to the southern melon bean main production area, Jin Zhengda senior agronomist combined with the company's fertilizer to give a set of melon bean crop scientific fertilization program for the farmers to learn from:
Base fertilizer: The organic fertilizer is mainly used together with Jinzhengda quality compound fertilizer such as 15-15-15S and 17-17-17S. It is also possible to use Jinzhengda sulfur-based controlled release fertilizer such as 18-9-1818-8-16.
Melon topdressing: 7-10 times of topdressing in the whole growth period. In the result period, every 7-10 days, chase 1 fat dressing to Jinzhengda Nitro Fertilizer 21-6-13, 15-5-20 and sulfur base fertilizer 18-5-28 , 16-6-24 and so on.
Bean top dressing: chasing 1 time in the seedling stage, flowering and pod-forming period, 2 times per application of nitro-fertilizer, about 20 kg of nitro-fertilizer, or application or application. The topdressing is mainly based on Jinzhengda Nitro Fertilizer 21-6-13, 15-5-20 and sulfur base fertilizer 18-5-25, 16-6-24.
