Watermelon is suitable for growing on fertile sandy loam or clay loam, and it is a mature farmyard manure. We have different growth of nutrient uptake of a significant difference in germination of 0.01%, accounting for 0.54% of the seedlings vining of 14.6%, a result of the absorption of nutrients watermelon most productive period, 84.88% of the total amount of nutrients Thus, the importance of nutrition in the late stage of watermelon can be seen.
1. Base fertilizer: There are many forms of application methods such as application, ditch application and acupoint application. Generally, 1 to 1.5 tons of farmyard manure per acre is applied , and 20-25 kg of superphosphate (including more than 12% of available phosphorus ) and 2.5-3 kg of potassium sulfate are mixed, mixed with soil, and then covered with soil, ready for planting or live broadcast.
 2, dressing: watermelon dressing are very different depending on the number of different planting patterns and different regions, the number of small dressing area dry melon, melon irrigated large number of top dressing (Dole dilutions). Usually when the seedlings grow true leaves 2 (live vaccine) or Huanmiao (transplanting seedlings) that is the first dressing, in an arcuate opening distance of 15cm at a shallow seedlings, as 15-20 g urea per plant Lift the seedlings. When the melon seedlings are vine, the cake fertilizer is applied to the plant between the plants or the back side of the plant (in the opposite direction to the alfalfa), each plant is 100-150 g or 50-100 g ternary compound fertilizer. When the young fruit has a diameter of about 5cm , it will apply 10-15 kg of urea and 7-10 kg of potassium sulfate . Young fruit diameter of 10-15cm, urea Mushi 10-15 kg, potassium 10-15 kg. From young fruit before enlargement to fruit ripening, foliar spray 3-4 times more music, calcium ** dilution 2-3 times, to increase the yield and improve the quality of watermelon, a significant effect.
As the second crop ready to harvest melons, melon crop should be harvested before the first 5 days, 90-120 kg per hectare topdressing urea, potassium sulfate 150-225 kilograms, spraying Dole, stems and leaves to prevent premature aging To promote the development of the second melon.
