Key points of cultivation of bracken

Bracken is a kind of wild vegetable preferred by northerners, which is called Shanzhen, and it is also expensive, so it is called the king of wild vegetables.

Reproduction

There are two ways of reproduction of bracken, namely sexual reproduction (spore reproduction) and asexual reproduction (rhizome ramet propagation). There are many methods of asexual reproduction in production. Asexual reproduction, dig out the underground rhizome, select the strong plant, row spacing 70~80cm, plant spacing 50~60cm, seedling height 10~15cm.

Make a bed by preparing the ground

It is appropriate to select the soil rich in humus and apply deciduous compost and stable manure to make a flat or high bed with a width of 1m, which can be planted after the soil is thawed.

Field management

During the growth period, it should be ploughed, weeded and irrigated frequently, and drainage should be strengthened in the rainy season so as not to cause root rot; if thin fertilizer is applied many times, one fertilizer can be harvested once, and fertilization should be carried out 2-3 days after harvest; it should be covered with withered grass in winter to protect against cold; timely watering and topdressing should be used before germination in early spring to promote stem and leaf germination.

Harvest

Bracken can be harvested once for more than 10 years, and can be harvested every spring and early summer when the young stem grows to 20~25cm, the petiole is young, and the leaflet is fist-hook-shaped before it is unfolded. After the party will affect the edible value, and will have a negative impact on the harvest in the coming year, too early will reduce the yield. When harvesting, you can cut it with a knife or pinch it with your hands, and keep it close to the ground as close as possible. After one harvest, it can be harvested for the second time in 10-15 days and 2-3 times a year.
