How to fertilize melon vegetables

How to fertilize melons is the key to increasing the yield of melons. The practical experience of vegetable farmers is to look at the land and see how to fertilize vegetables.
"Look at the days of fertilization," that is, do not apply fertilizer on rainy days to avoid the loss of fertilizer. Days of nausea are not applied, the fog is not applied, the temperature is not applied, so as not to cause the disease of rotten plants, fertilization should be selected sunny. "see fertilization", that is, soil less good, poor soil quality and more. Excessively hardened, hard-to-prepare organic fertilizers, etc., should be properly applied, and should be applied sparingly, thinly, repeatedly, and in small quantities. In the seedling stage of the melons, the cleansing water with a concentration of 10% to 15% is generally applied, and as the plants grow, they can be gradually thickened. By the late growth period, it can generally be increased to 30% -40%.
To fertilize vegetables, you need to know how to identify which fertilizer is lacking in vegetables. Also learn to "six look":
A look at the type of fertilization: legume rhizobia nitrogen fixation, the need for less nitrogen, the need for more phosphate; root vegetables, dioscorea needs more potassium; leafy vegetables only need more nitrogen fertilizer; fruit and vegetable in the application of nitrogen fertilizer Based on the above, it is necessary to use phosphorus and potash fertilizers.
Second, see soil fertilization: different soil quality, fertilization methods are not the same. The light loam soil pellet structure has good fertilizer and fertilizer performance, and can be applied and reused. The sandy loam was used less frequently to prevent fertilizer waste. At present, many vegetable farmers neglect farmyard manure and phosphorus and potash fertilizers, leading to imbalances in the nutritional ratio of vegetables and should be improved in time.
Third, the climate and fertilization: high temperatures in summer, fast decomposition of fertilizers, rain, fertilizer is easy to lose. When fertilizing, a small quantity and multiple methods should be adopted, and the decomposed farmyard fertilizers should be applied timely and dispersedly. Apply more on sunny days and less on rainy days. On the contrary, in winter, the temperature is low and there is little rain. The decomposed farmyard fertilizer should be applied early and the chemical fertilizer should be developed.
Fourth, look at the seedling fertilization: see seedlings fertilization generally grasp the "fewer seedling period, stable flowering period, fruit weight" principle, the early stage of nitrogen-based, in the middle and late nitrogen, phosphorus and potassium. However, varieties have different ripeness and fertilization. Early maturing cultivars have a short vegetative growth period, and they should focus on the promotion in the early stage and lay the foundation for high yields. Late maturing cultivars have a long period of vegetative growth, and early-stage cultivars focus on the control and promotion of binding to enable the seedlings to grow steadily.
Five fertilizers fertilization: farm fertilizer effect long, full of nutrients, not easy to cause leggy, generally used as base fertilizer, long-term breeding varieties can be buried fertilizer method. Fertilizer fertilizer effect is fast, nutrients are incomplete, fertilizer thick easily lead to leggy, only suitable for top dressing and a small amount of base fertilizer. Ammonium bicarbonate is volatile and can be used as a base fertilizer. If it is used for topdressing, it should be applied 10 centimeters away from the roots of the crop, and it should be covered in a timely manner to avoid smudging crops. Urea is generally used as top dressing and should be applied 4 to 6 days in advance in order to exert its fertilizer effect. Phosphate mobility is small, generally for fertilizer, top dressing. For topdressing, it is necessary to open the ditch and apply it to the root layer.
Six fertilization: Ammonium bisulfate, human fecal urine and other nitrogen fertilizers are acidic and cannot be mixed with alkali ash such as grass ash to avoid reducing fertilizer efficiency. Superphosphate cannot be mixed with acidic fertilizers. Ammonium bisulfate and urea are in contact with species, stems and leaves, which can cause burns. Urea is used as top-dressing fertilizer, and its concentration must not exceed 1%. Ammonium chloride and potassium chloride cannot be used on bogey crops such as potatoes.
