What are the cultivation methods for the wild vegetable variety Wei cai (Osmunda japonica, royal fern)?
If you have friends who love wild vegetables, you should be quite familiar with the variety that the editor is about to introduce. Wei cai is also a wild vegetable, but its market share is not large, and it is not as widely popular as other wild vegetables. In fact, Wei cai is very similar to fiddlehead fern, and in recent years it has also become very popular among some groups, so more and more growers are cultivating it. So are you clear about how to grow Wei cai? Let's take a look together!
How to grow Wei cai?
1. Soil improvement
Wei cai does not have high requirements for soil, but it is still recommended that you choose soil with good drainage, which is more suitable. If the ambient temperature is too low, do not plant just for yield; wait until the ambient temperature gradually rises before starting, otherwise temperatures that are too low or too high are both unfavorable for Wei cai. Moreover, Wei cai also has relatively high requirements for moisture control. Although it likes a humid environment, you should not water too much, as affecting the roots can cause rot problems. Also, the soil at the planting site is best if it is acidic soil, with relatively sufficient humus in the soil, and the soil texture should preferably be loose on top and firm below, and it is best to have a half-shade and half-sun area, or some shade-providing objects. After choosing the planting site, we need to apply fertilizer to improve the soil. Generally, the amount used per mu is about six hundred jin, mainly farmyard manure such as chicken manure, pig manure, and cow manure, applied together with deep plowing.
2. Planting and setting out
Wei cai is generally planted and established by hole sowing or drill sowing. For hole sowing, the main thing is to master the distance between each hole, because this is very helpful for subsequent growth. The row spacing for drill sowing is also key. When planting, note that each hole should have at least two to three seedlings, and the planting density of Wei cai per mu is about four thousand to five thousand plants. We should reasonably control the planting density, because being too dense or too sparse will affect the later economic returns of Wei cai.
3. Later management
Wei cai likes a humid environment, so after planting, we should water frequently to keep the soil moist, but we must also control the amount of water. The moisture should not be too great, otherwise it will cause the roots of Wei cai to rot. Next is to clear the weeds in the field. About half a month after Wei cai emerges, we should carry out one intertillage and weeding. This can not only reduce nutrient loss, but also improve soil permeability, promote nutrient absorption, and increase the growth rate of Wei cai.
That is all that Tuliu Network will introduce to everyone today about the planting of Wei cai. Although Wei cai cultivation is now common, there are still not many people growing it, so there is still a very good market in this area. Everyone should pay attention to the finishing work after harvesting, and cover with shade cloth in time to prevent the plants from aging.
