The Latest Technical Method Tutorial for Pollution-Free Cultivation of Celtuce
Celtuce is a very common vegetable in our daily lives. Both its leaves and stems can be eaten, and it is well liked by many people. Therefore, the planting area of celtuce is now relatively large, but when growing celtuce, it is often troubled by pests and diseases, which leads to reduced yields. Therefore, the pollution-free cultivation technique for celtuce is very important. So below, the editor has brought you the pollution-free cultivation technique for celtuce. Let's take a look together!
1. Soil preparation
If celtuce is to achieve the goal of pollution-free cultivation, then the first thing to do well is the selection of soil. Soil that is soft, has normal drainage and irrigation, is rich in humus, and has good water and fertilizer retention should be the main choice. After selecting the soil, do a good job of land preparation, and deeply plow and sun the soil. Also apply sufficient base fertilizer, mainly farmyard manure, at about 2000kg per mu. After sunning the soil clods for about a week, finely prepare the land, then open furrows at a specification of about 185 cm. If planting in the current season, then flat furrows should be mainly used; otherwise, high furrows should be mainly used.
2. Sowing and planting
After completing the soil preparation work, we also need to disinfect the soil once, using agents such as Lorsban for drenching application, to avoid celtuce being affected by pests. After disinfection, sow appropriately, mainly by broadcasting, and control the sowing rate well. Usually the sowing rate per mu is about 30 grams, and it should not be too much, otherwise it is easy to cause overly dense growth. After sowing, cover with a layer of fine soil, just enough to cover the seeds, and then cover the soil with a layer of rice straw. Then, when the seedlings grow to about 8 cm, transplant them. Seedlings that have already swollen should not be transplanted, to avoid early bolting.
3. Field management
After the celtuce seedlings are transplanted, pay attention to watering immediately to avoid the seedlings dying from lack of water. Then, after the seedlings survive, appropriately apply ammonium hydrogen carbonate, calcium superphosphate, etc. by watering, to promote seedling growth. After that, control the amount of fertilizer and water well, and do a good job of intertillage. After entering the rosette stage, water and fertilize more again. The fertilizer should be mainly urea, about 12kg per mu, supplemented by potassium sulfate, about 5kg per mu, and then the soil should be kept alternately dry and wet. Finally, when the leaf surface closes the rows and the stem begins to swell, carry out the last topdressing, mainly with compound fertilizer.
4. Pest and disease control
Finally, we must do a good job in preventing and controlling celtuce pests and diseases. Celtuce is most vulnerable to downy mildew. It is most likely to occur especially in high-temperature and high-humidity environments. Therefore, we must do a good job of prevention, and about 3 weeks after planting, appropriately spray agents such as metalaxyl mancozeb for control. Also pay attention to controlling sclerotinia rot, leaf spot disease, and thrips, etc. All should focus on prevention, strengthen management, do a good job of intertillage, and control the temperature and humidity in the field. Avoid unsuitable temperature and humidity creating conditions for pathogens to cause disease.
The above is a brief introduction to the pollution-free cultivation technique for celtuce. Pollution-free cultivation can effectively improve the quality and yield of celtuce, and can also expand planting benefits, so everyone can try it more. That is all for today's introduction.
