How to Fertilize Celtuce? Detailed Explanation of Key Fertilization Techniques
Celtuce is a stem vegetable that many people enjoy eating very much, and it has a rather strong aroma. Today, celtuce is grown on a very large area in China. When growing celtuce, management work must be done well. Among this, fertilization is a very important task in management. So how should celtuce be fertilized when growing it? Below, the editor brings you the fertilization techniques for celtuce. Let's take a look together!
1. Fertilizer Requirements and Characteristics
Celtuce likes to grow in a warm environment, has very poor cold resistance, and has relatively large demands for water and nutrients. The main edible part of celtuce is the underground stem, so its requirements for soil are relatively high. When planting, make sure the soil has strong permeability and is deep and loose. During the growth process of celtuce, its nutrient demands change with different growth stages. During the vigorous growth period, its fertilizer requirement is very large, so attention should be paid to timely fertilization. Then, at the final maturity stage, the amount of fertilizer applied should be appropriately reduced to prevent a decline in storage capacity. Finally, celtuce has the greatest demand for potassium, followed by nitrogen, and finally phosphorus.
2. Apply Sufficient Base Fertilizer
The root distribution of celtuce is relatively shallow, with a depth of about 25 cm. Therefore, the application of base fertilizer is very important. Applying sufficient base fertilizer is the key to ensuring the robust growth of celtuce. It is also an indispensable task for cultivating high-quality strong seedlings. We should control the amount of fertilizer according to the planting area. Generally, about 4500 kg of base fertilizer is applied per mu. The base fertilizer is mainly decomposed farmyard manure, combined with an appropriate amount of superphosphate, plant ash, and other materials. This promotes the growth of celtuce and meets its nutrient needs during growth.
3. Reasonable Topdressing
When growing celtuce, we should carry out reasonable topdressing work according to the season. Spring celtuce is generally planted around September of the previous year, and then enters a dormant period in winter and stops growing. When topdressing spring celtuce, the principle of applying more frequently and in small amounts should be followed. After transplanting, the first topdressing can be carried out to improve the survival rate after transplanting. Then, about half a month after transplanting, topdress again. The topdressing fertilizer can also be mainly farmyard manure. However, if the soil fertility is high and the base fertilizer is sufficient, the amount of topdressing can be reduced or even no topdressing may be needed. On the contrary, if fertility is insufficient, more topdressing should be applied.
4. Topdressing During the Rosette Stage
The topdressing work during the rosette stage and fleshy formation stage of celtuce is very important. Nutrients at this time directly affect the yield. When celtuce is around 4 months into the head-forming stage, the demand for nitrogen rises sharply. Therefore, attention should be paid to appropriately increasing nitrogen, and then also to supplementing appropriate amounts of calcium, iron, and other nutrient elements. This promotes leaf growth, enhances photosynthetic capacity, and increases the accumulation of photosynthetic substances in celtuce. Then, according to the actual conditions such as the growth stage of celtuce, reasonably supplement nutrients and carry out topdressing to meet the nutrients needed for the rosette and expansion of celtuce.
The above is a brief introduction to celtuce fertilization techniques. The fertilization work for celtuce is very important and directly affects our planting benefits, so everyone must pay close attention! That is all for today's introduction.
