The latest course on fertilization techniques of cantaloupe

Hami melon is a unique fruit in Xinjiang, China, with sweet taste, high nutritional value, large market demand and wide planting area. If you want to plant cantaloupe well, you must first do a good job of fertilization, so how to fertilize cantaloupe? Let's take a look at the detailed introduction.

1. Characteristics of fertilizer requirement

For the three conventional fertilizers of nitrogen, phosphorus and potassium, potassium is the most, followed by nitrogen and phosphorus. According to research, for every 100 kilograms of fresh Hami melon, it is necessary to absorb 2.5-3.5 kg of nitrogen, 1.3-1.7 kg of phosphorus and 4.4-4.6 kg of potassium from the soil. During the fruiting period when the fertilizer demand is the highest, we should grasp the principles of applying sufficient base fertilizer, re-applying melon fertilizer and skillfully applying foliar fertilizer, with organic fertilizer as the main fertilizer and chemical fertilizer as the auxiliary.

2. Apply sufficient base fertilizer

Base fertilizer should be combined with organic fertilizer and inorganic fertilizer to increase sufficient nutrients before flowering and speed up the growth of Hami melon. The root system of Hami melon is shallow, and base fertilizer is generally applied with 3000-4000 kg of mature farm manure per mu. With 15 kg of potassium sulfate, 25 kg of compound fertilizer and 0.5-1 kg of borax. When combined with soil preparation, it is applied to the bottom of the ridge, and after application, it is necessary to cover a layer of shallow soil to avoid direct contact with the root system of the seedlings, resulting in the phenomenon of burning seedlings and roots.

3. Heavy application of flower and fruit fertilizer

After entering the flower and fruit stage of Hami melon, the nutrients absorbed by Hami melon show a gradual increasing trend, so it is necessary to topdressing 2-3 times in time, mainly nitrogen fertilizer in the early stage, combined with appropriate amount of phosphorus and potassium fertilizer to promote the early growth and rapid development of melon seedlings. When the fruit is set and the fruit is in the expansion period, the demand for fertilizer reaches its peak, so it is necessary to re-apply fertilizer, mainly potash fertilizer, and control the amount of nitrogen fertilizer to avoid excessive growth of branches and leaves. Generally, 10-15 kg potassium sulfate compound fertilizer is applied per mu, and again after 7-10 days, and 5-10 kg potassium sulfate compound fertilizer is applied per mu.

4. Skillfully applying foliar fertilizer

Hami melon also needs a variety of trace elements when growing, and the root system is relatively shallow, which can not be absorbed and utilized in time after fertilization, so foliar fertilizer spraying should be adopted. Foliar fertilizer spraying has the characteristics of less fertilizer and quick effect. generally, when the plant is lack of nutrients, it can spray low concentration fertilizer solution, which can replenish the corresponding nutrients very quickly.
