2. Apply enough base fertilizer. Generally, organic fertilizer and inorganic fertilizer should be used in combination with base fertilizer to increase sufficient nutrients before the cantaloupe blooms and accelerate its growth. The root system of cantaloupe is relatively shallow. Generally, 3000~4000 kg of decomposed farm manure per acre is used for base fertilizer. With 15 kg of potassium sulfate, 25 kg of compound fertilizer, and 0.5 to 1 kg of borax. Combined with applying to the bottom of the ridge during soil preparation, cover a layer of shallow soil after application to avoid direct contact with the roots of the seedlings, resulting in seedling burning and root burning. 3. After the reapplication of flower and fruit fertilizer enters the flowering and fruit period of the cantaloupe, the nutrients it absorbs show a gradual increase. At this time, it is necessary to apply fertilizer 2~3 times in time. The first stage is mainly nitrogen fertilizer, with an appropriate amount of phosphorus and potassium fertilizer to promote The seedlings are early and fast. After the fruit is set, when the fruit reaches the swelling stage, the demand for fertilizer reaches its peak. Therefore, it is necessary to reapply fertilizer, mainly potassium fertilizer, and control the amount of nitrogen fertilizer to prevent the branches and leaves from growing. Generally, 10-15 kg of potassium sulfate compound fertilizer is applied per mu, and then applied again after 7-10 days, and 5-10 kg of potassium sulfate compound fertilizer is applied per mu. 4. Clever application of foliar fertilizers Hami melons still need a variety of trace elements during growth, and the root system is relatively shallow, and can not be absorbed and utilized in time after fertilization. At this time, foliar sprays should be used. Foliar spraying has the characteristics of less fertilizer and quick effect. Generally, when plants lack nutrients, you can spray a low-concentration fertilizer solution to quickly replenish the corresponding nutrients.

1. Characteristics of fertilizer requirements For cantaloupe, the three conventional fertilizers of nitrogen, phosphorus and potassium have the most potassium, followed by nitrogen, and the least phosphorus. According to research, every 100 kg of fresh cantaloupe needs to absorb 2.5 to 3.5 kg of nitrogen and phosphorus from the soil. 1.3~1.7 kg, potassium 4.4~4.6 kg. The period of the highest fertilizer requirement is the fruiting period. During production, the principles of applying sufficient base fertilizer, reapplying expanded melon fertilizer, and skillfully applying foliar fertilizer should be mastered. The fertilizer is mainly organic fertilizer, and chemical fertilizer is supplemented.
