Fertilization Technology of Hami Melon

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

1. Characteristics of fertilizer requirement

Hami melon for nitrogen, phosphorus and potassium three conventional fertilizers to potassium the most, followed by nitrogen, phosphorus the least, according to research shows that every production of 100 kg fresh Hami melon, it needs to absorb from the soil total nitrogen 2.5-3.5 kg, phosphorus 1.3-1.7 kg, potassium 4.4-4.6 kg. The principle of applying enough base fertilizer, heavy fertilizer and foliar fertilizer should be mastered during production. Organic fertilizer is the main fertilizer and chemical fertilizer is the auxiliary fertilizer.

2. Apply enough basal fertilizer

Base fertilizer is generally suitable for organic fertilizer and inorganic fertilizer to be applied together, so as to improve sufficient nutrients before flowering and accelerate the growth of Hami melon. The root system of Hami melon is shallow. The base fertilizer is generally applied with 3000-4000 kg of decomposed 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 should be applied to the bottom of the ridge, and a layer of shallow soil should be covered after application, so as to avoid direct contact with the roots of seedlings, resulting in burning seedlings and roots.

3. Heavy application of flower and fruit fertilizer

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

4, clever foliar fertilizer

Hami melon also needs a variety of trace elements when growing, and the root system is shallow, so it cannot be absorbed and utilized in time after fertilization, which is to use foliar spray fertilizer. Foliar fertilizer has the characteristics of less fertilizer and quick effect. Generally, when the plant lacks nutrients, it can spray low concentration fertilizer solution, which can quickly supplement the corresponding nutrients.
