Detailed Explanation of Key Points for Scientific Fertilization Techniques for Hami Melon
Hami melon is a fruit unique to China, with a sweet taste and high nutritional value. It is in relatively high demand on the market and is grown over a fairly wide area. To grow Hami melon well, the first thing to do is proper fertilization. So how should Hami melon be fertilized? Let's take a look at the detailed introduction below.
1. Fertilizer Requirements
Among the three conventional fertilizers nitrogen, phosphorus and potassium, Hami melon takes up the most potassium, followed by nitrogen, and the least phosphorus. According to research, for every 100 kg of fresh Hami melon produced, 2.5-3.5 kg of nitrogen, 1.3-1.7 kg of phosphorus and 4.4-4.6 kg of potassium need to be absorbed from the soil in total. The period of highest fertilizer demand is the fruiting stage. During production, the principles of applying sufficient base fertilizer, heavily applying fruit-swelling fertilizer and skillfully applying foliar fertilizer should be mastered, with organic fertilizer as the main type and chemical fertilizer as a supplement.
2. Apply Sufficient Base Fertilizer
Base fertilizer should generally be applied as a combination of organic and inorganic fertilizers, to provide sufficient nutrients for Hami melon before flowering and speed up its growth. Hami melon has a relatively shallow root system, so the base fertilizer is generally applied at 3000-4000 kg of decomposed farmyard manure per mu, together with 15 kg of potassium sulfate, 25 kg of compound fertilizer and 0.5-1 kg of borax. Apply it into the bottom of the ridge when preparing the land. After application, cover it with a layer of shallow soil to avoid direct contact with the seedling roots, which could cause seedling burn and root burn.
3. Heavily Apply Flower and Fruit Fertilizer
After Hami melon enters the flowering and fruiting stage, its nutrient uptake shows a gradually increasing trend, so at this time it should be topdressed 2-3 times in time. In the early stage, nitrogen fertilizer is the main type, combined with an appropriate amount of phosphorus and potassium fertilizer, to promote early growth and rapid development of the melon seedlings. After fruit set, when the fruit reaches the swelling stage, the demand for fertilizer peaks at this time, so fertilizer should be applied heavily, mainly potassium fertilizer, while controlling the amount of nitrogen fertilizer to avoid excessive vegetative growth of branches and leaves. Generally, 10-15 kg of potassium sulfate compound fertilizer is applied per mu, and after 7-10 days another application is made, with 5-10 kg of potassium sulfate compound fertilizer per mu.
4. Skillfully Apply Foliar Fertilizer
During growth, Hami melon also needs various trace elements, and because its root system is relatively shallow, it cannot absorb and utilize nutrients in time after fertilization, so the foliar spraying method should be used. Foliar spraying has the characteristics of a small fertilizer amount and quick results. Generally, when the plant lacks nutrients, a low-concentration fertilizer solution can be sprayed to replenish the corresponding nutrients very quickly.
