Base fertilizer: mainly based on organic fertilizer, combined with Jinzhengda quality compound fertilizer such as 15-15-15S, 17-17-17S. It is also possible to use Jinzhengda sulfur-based controlled release fertilizer such as 18-9-18, 18-8-16 and the like.
Melon topdressing: topdressing 7-10 times in the whole growth period, chasing fertilizer once every 7-10 days in the result period, topdressing with Jinzhengda nitro fertilizer 21-6-13, 15-5-20 and sulfur base fertilizer 18-5 -28, 16-6-24 and so on.
Bean topdressing: chasing 1 fat in the seedling stage, 2 times in the flowering and pod-forming period, each application of 20 kg of nitro-fertilizer, can be applied, applied or applied. 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.
The importance of fertilizing potassium in melon
Melon beans such as cucumber, loofah, pepper, green beans, etc., are typical potassium-producing 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 foliar application of calcium fertilizer has a certain yield increase effect. Through a survey of the main melon bean production areas in the south, Jin Zhengda's 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:
