In the process of planting watermelon, how to make watermelon seedlings grow fast and strong is a problem that every melon farmer is concerned about. Proper fertilizer selection plays a key role in the rapid growth of watermelon seedlings. So, what fertilizer can be used to make watermelon seedlings grow faster?
First of all, we need to understand the main nutrients needed for the growth of watermelon seedlings. Nitrogen, phosphorus, and potassium are the three key elements for watermelon growth, and they are all essential for plant growth, flower bud differentiation, and fruit development. In addition, watermelon seedlings also need a moderate amount of trace elements to maintain healthy growth.
1.Organic fertilizer: Organic fertilizer is the first choice to make watermelon seedlings grow fast. It is not only rich in major nutrients such as nitrogen, phosphorus, and potassium, but also rich in organic matter and trace elements. Organic fertilizers can improve soil structure, increase soil fertility, and provide long-term nutrient support for watermelon seedlings. Common organic fertilizers include well-rotted farmhouse manure, manure, compost, etc.
2.Compound fertilizer: Compound fertilizer is a fertilizer specially formulated for crops, which contains the main nutrients needed for the growth of watermelon seedlings. Choosing the right compound fertilizer can meet the nutrient needs of watermelon seedlings at different growth stages. When using compound fertilizers, it is necessary to apply fertilizer reasonably according to the product instructions and the growth condition of the plants.
3.Water-soluble fertilizer: Water-soluble fertilizer has the characteristics of rapid dissolution and absorption, which can quickly provide nutrients for watermelon seedlings. At the seedling stage, water-soluble fertilizers can be used appropriately to promote the growth of plants, but attention should be paid to controlling the concentration and avoiding burning seedlings.
4.Foliar fertilizer: Foliar fertilizer is a fertilizer that provides nutrients to the plant by spraying it on the leaves. It can supplement the nutrient deficiency that may occur in the growth process of the plant, improve the efficiency of photosynthesis, and promote the growth of watermelon seedlings. Foliar fertilizer should be used with attention to concentration and spraying time.
In addition to choosing the right type of fertilizer, the right fertilization method is also crucial. When fertilizing, pay attention to the following:
1.Moderate fertilization: Excessive fertilization may cause damage to watermelon seedlings and even lead to seedling burning. According to the soil fertility and plant growth status, the amount of fertilizer should be reasonably controlled.
2.Phased fertilization: According to the growth stage of watermelon seedlings, fertilization is carried out in stages. The nutrients required for the seedling stage, growth period and fruiting period are different, and fertilizers should be selected in a targeted manner.
3.Deep application of soil covering: Applying fertilizer deep into the soil and covering it with a layer of soil can reduce the volatilization and loss of nutrients and improve the utilization rate of fertilizer.
4.Combined watering: Watering in time after fertilization helps the dissolution and penetration of fertilizer, so that the plant can better absorb nutrients.
In addition, attention should also be paid to the pH and air permeability of the soil, maintain the appropriate humidity and temperature of the soil, and create a good growth environment for watermelon seedlings.
To sum up, choose the right type of fertilizer and use positive.
The exact fertilization method can effectively promote the rapid growth of watermelon seedlings. However, soil and climatic conditions vary from region to region, so it is best to make appropriate adjustments according to the actual situation during the fertilization process. At the same time, regularly observe the growth of watermelon seedlings, and carry out reasonable pruning and pest control as needed to ensure that watermelon seedlings thrive and lay a solid foundation for a bumper harvest.
