Asparagus is also called asparagus. The extracted tender stems are edible vegetables with rich nutrition. The health care effect is very good, and it has the reputation of the king of vegetables. So the market is very popular with consumers, and now farmers have more friends. So how do you grow asparagus? Let's get to know it together!
1, seedling raising
Seed treatment: pay attention to drying the seeds before sowing, then soak them in warm water, rub them, soak them in carbendazim for disinfection, and then rinse them with clear water to accelerate germination.
Seedling raising method: plant asparagus on the seedbed, pour enough decomposed farmyard manure, and cooperate with a small amount of compound fertilizer to improve nutrients for asparagus seedling raising.
2. Seedling management
Pay attention to the water supply of asparagus at seedling stage, which is the key to maintain the rapid growth of asparagus. In the process of planting, nitrogen fertilizer should be applied reasonably and biostimulants should be sprayed 500 times. And do weeding work in time.
Step 3 plant
Asparagus seedlings can be transplanted and planted when they grow to a certain height, and they should be watered enough. After digging the planting hole, the planting operation should be completed and a small amount of base fertilizer should be sprinkled to cultivate the soil.
4, intertillage and cultivate soil
Young asparagus is easy to grow weeds, so it should be pulled out in time. Generally, intertillage and weeding are carried out together, and the soil is covered by planting ditches in stages.
5. Water and fertilizer management
The growth of asparagus at seedling stage should ensure sufficient nutrient supply and reasonable topdressing every month. Fertilizers are mainly nitrogen fertilizer and compound fertilizer, which should be well fertilized in autumn to lay the foundation for high yield. At the mature stage, strong bamboo shoot fertilizer should be applied, with high nitrogen and quick-acting fertilizer as the main fertilizer, combined with sea elf biological stimulator.
Step 6 harvest
Asparagus is harvested for a long time, usually from April to August. Relay fertilization should be supplemented when harvesting, and harvesting should be stopped when only 5~7 buds germinate in the bud tray, so as not to affect the bamboo shoot harvest next year.
