Watermelon Fertilizing Time
A comprehensive introduction to the life knowledge of watermelon fertilizing time, including the best fertilizing time for watermelons. Corrections are welcome if there are any mistakes!
1. Do not apply a large amount of nitrogen fertilizer alone. Before the watermelon sets fruit, fertilizing focuses on nitrogen nutrition; after the fruit sets, the absorption of potassium increases dramatically; during the hair removal stage of watermelon, the amounts of nitrogen and potassium are roughly equal, reaching a peak during the expansion stage; during the maturation stage, the absorption of nitrogen and potassium decreases significantly, while the absorption of phosphorus relatively increases. The ratio of nitrogen, phosphorus, and potassium during the seedling stage is 3.8:1:2.8; during the vine stretching stage, it is 3.6:1:1.7; and during the fruit growth peak stage, it is 3.5:1:4.6.
2. Do not apply chlorine-containing fertilizers. Watermelon is a chlorine-sensitive crop, and applying chlorine-containing fertilizers during the planting process can affect the accumulation of sugars, making the fruit taste bland, such as chlorinated ammonium, chlorinated potassium, or chlorinated potassium compound fertilizers.
3. Do not over-apply human waste. Overuse of human waste during watermelon cultivation can easily cause the plant to grow too much, making it difficult to set fruit, and can also make the watermelon skin thick and the taste sour.
4. Pay attention to deep application when top-dressing watermelon. After applying fertilizer to watermelon, cover the soil in time, especially after applying nitrogen fertilizer. If nitrogen fertilizer is applied to the surface soil, nitrogen can easily volatilize and form ammonia gas, which can harm the leaves and also reduce the efficacy of the fertilizer.
5. Avoid fertilizing during cloudy and rainy weather. In cloudy and rainy conditions, the air humidity is high, and the soil moisture content is high. If fertilizing at this time, not only will it cause fertilizer loss, but it can also easily cause the watermelon to grow too much.
The above is a comprehensive explanation of the method for the watermelon fertilizing time and the best fertilizing time for watermelons. I hope it can act as a stepping stone to solve your problems in life.
