Watermelon cultivation requires careful management of fertilization to ensure healthy growth and high-quality fruit. One common mistake is applying a large amount of nitrogen fertilizer in a single dose. This can lead to excessive vegetative growth, making the plants leggy and less likely to produce flowers or fruits effectively. Before the watermelon starts setting fruit, potassium uptake increases significantly after the fruit has set. During the early fruit development stage, the absorption of nitrogen and potassium is roughly equal, but during the full fruiting stage, potassium uptake peaks while nitrogen absorption decreases. At the same time, phosphorus uptake increases slightly. The ideal N:P:K ratio varies depending on the growth stage: 3.8:1:2.8 during the seedling phase, 3.6:1:1.7 during the vine extension period, and 3.5:1:4.6 during the fruiting stage.
Second, avoid using chlorine-containing fertilizers such as ammonium chloride or potassium chloride. Although watermelons are somewhat tolerant to chlorine, excessive use can reduce sugar accumulation and negatively affect the flavor of the fruit, making it less sweet.
Third, do not overuse human manure. Excessive application can cause the plants to grow too vigorously, leading to poor fruit setting, thick rinds, and an increased risk of disease.
Fourth, avoid applying fertilizer directly on the surface soil. Watermelon fertilizers should be applied at a deeper level and covered promptly. Nitrogen, in particular, is prone to volatilization if left exposed, which can result in ammonia gas emissions that damage leaves and reduce fertilizer efficiency.
Fifth, avoid fertilizing during rainy weather. High humidity and wet soil conditions can lead to nutrient runoff and leaching, reducing the effectiveness of the fertilizer. Additionally, excessive moisture can promote rapid, uncontrolled plant growth.
Sixth, never place fertilizer too close to the main roots. It's recommended to apply fertilizer about 10 centimeters away from the root zone to prevent root burn and ensure proper nutrient absorption without damaging the plant.
Lastly, avoid applying fertilizer during dry periods. When the soil is dry and moisture levels are low, applying chemical fertilizers can cause the root cells to lose water, leading to physiological drought and even plant death. Always ensure the soil is adequately moist before applying any fertilizer to maintain plant health and optimize nutrient uptake.
Drug Intermediates
Drug intermediates are compounds that are formed during the synthesis of a pharmaceutical drug include API intermediates,chemical intermediates,medicine intermediates . They are the intermediate products that are used to create the final drug product. These intermediates are usually organic compounds that have specific chemical properties and structures that are necessary for the synthesis of the drug. The synthesis of drug intermediates involves a series of chemical reactions and purification steps that are carefully controlled to ensure the purity and quality of the final product. The drug intermediates are then further processed to create the final drug product that is used for medical treatment.Our main intermediates are 3,3′-Diindolylmethane,2,3,4,5-Tetrafluorobenzoic acid,
2, 6-Difluorobenzamide,2, 6-Difluorobenzoic Acid.China Drug intermediates,API intermediates manufacturers, welcome chemical intermediates,medicine intermediates purchasers from worldwide to visit our site to learn more.
