Is bracken poisonous?

1. Bracken is slightly toxic because bracken contains a substance called proferrin, which can cause cancer and increase the incidence of gastric and esophageal cancer, so it is not suitable for consumption, but it will be fine if eaten in small amounts.

2. Bracken is slightly toxic, and eating too much will cause diarrhea, indigestion and other uncomfortable symptoms, so it is best to soak in water for 2 hours or soak in plant ash for a period of time to reduce the toxicity. Under normal circumstances, it is recommended to eat about 30g each time, do not eat too much, so as not to cause discomfort.

Second, what are the planting techniques of bracken?

1. Land selection and preparation: which land is suitable for planting?

Bracken is suitable to grow in the acid environment where the soil is loose and fertile and the terrain is relatively flat, so when selecting land, try to choose acidic loam or sandy loam for planting. After selecting the site, it is necessary to dig the soil deeply, and then make ridges and ditches for later management.

2. Breeding seedlings: how to reproduce?

The main results are as follows: (1) Propagation methods: bracken can use sexual reproduction and asexual reproduction, in which sexual reproduction is to sow and raise seedlings with seeds, and then transplant them. Asexual reproduction is to transplant new seedlings to the soil according to the spacing of 60cm and 70cm, while asexual reproduction is mostly used in daily life.

(2) planting time: it can be planted all the year round, but it is best to plant it from March to April and September.

3. Field management technology: how to manage it?

(1) Water requirement: bracken likes to grow in a humid environment, so it should be watered more in summer and less in winter. In general, it can be watered every two or three days in dry weather.

(2) Fertilizer requirements: during the growth of bracken, some base fertilizer should be added timely, and in the early stage of harvest, more base fertilizer should be added to promote plant growth.

(3) weeding in the middle ploughing: during the growth period of bracken, the weeds in the garden should be removed in time, and the soil should be loosened to improve the soil permeability.

(4) do a good job of heat preservation measures in winter: before winter, cover bracken with a layer of straw to keep warm and let the seedlings grow healthily.

4. Timely harvest: when will the harvest be ready?

Bracken is harvested in batches, generally the first harvest is when the bracken seedlings grow to 20~40cm, and only a fresh and tender part is harvested, and it can be harvested again ten days later, usually three or four times a year.

The above is a detailed introduction of whether bracken is poisonous and planting technology. I hope it will be helpful to you.
