How to Fertilize Celtuce: Latest Technical Method Tutorial
Celtuce is a stem vegetable that many people enjoy eating very much, with a fairly strong aroma. At present, the planting area of celtuce in our country is very large. When planting celtuce, the 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 Requirement 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, the soil must have strong permeability and be deep, loose and soft. During the growth process of celtuce, its nutrient demands will differ as the growth stages change. During the vigorous growth period, its fertilizer requirement is very large, so attention must be paid to timely fertilization; then in 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 lastly phosphorus.
2. Apply Sufficient Base Fertilizer
The roots of celtuce are distributed relatively shallowly, at a depth of about 25 cm. Therefore, applying base fertilizer is very important; applying sufficient base fertilizer is the key to ensuring 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 nutritional needs during growth.
3. Reasonable Topdressing
When planting 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 dormancy in winter and stops growing. When topdressing spring celtuce, the principle of applying more frequently but in small amounts should be followed. After planting, the first topdressing can be carried out to improve the survival rate after planting. Then about half a month after planting, 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 omitted; on the contrary, if fertility is insufficient, more topdressing should be applied.
4. Topdressing at the Rosette Stage
The topdressing work at the rosette stage and the fleshy stem formation stage of celtuce is very important. At this time, nutrition directly affects the yield. When celtuce is about 4 months into the head formation stage, the demand for nitrogen rises sharply. Therefore, attention should be paid to appropriately increasing nitrogen, and then also to supplementing an appropriate amount of calcium, iron and other nutrient elements. This promotes leaf growth, enhances photosynthetic capacity, and improves the accumulation of photosynthetic substances in celtuce. Then, according to the growth stage of celtuce and other actual conditions, reasonably supplement nutrients and carry out topdressing to meet the nutrients needed for the rosette stage 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.
