Key points of field management of bracken

Bracken is a very popular wild vegetable in China, and it has a very high status in our country. Due to the increase in market demand, people have no restrictions on excessive mining, and the number of wild people has dropped sharply. So now bracken also has a certain artificial planting area, but because it is a wild vegetable, so many people do not know how to manage it. So the editor below brings you the field management technology of bracken, let's have a look!

1. First year management

In the first year of bracken cultivation, we should do a good job in grasping seedlings, ensure strong seedlings, weed in time, and strengthen the management of water and fertilizer. Before planting, we should first irrigate enough water to improve the survival rate of bracken, and in order to prevent soil water shortage, but also often watering to increase soil water content. But the water should not be too much, if too much watering or encounter the rainy season, then it is necessary to timely drainage, to prevent too much water to return. Then properly cover the soil with straw leaves or plastic film to avoid light and heat preservation, but also can inhibit the growth of weeds. When bracken grows new seedlings, it should be fertilized once a month.

2. Management in the second year

The main direction of management in the second year is to cultivate high-quality roots and promote the formation of multiple buds in the roots of bracken. Then according to the nutritional needs of bracken and soil fertility and other reasonable topdressing, weeding. Pay attention to the amount of fertilizer when topdressing, not too much at a time, mainly in a small amount. Urea is the main fertilizer, which can effectively promote the reproduction of underground rhizomes. Pick a small amount in the second year, if possible, it is best not to pick. Then apply farm manure in autumn, do a good job of loosening the soil, and fully mix it with the soil, which can not only improve soil fertility, enhance soil quality, but also improve the cold protection and heat preservation of soil.

3. The third year of management

The growth ability of bracken is gradually strengthened in the third year, and a mid-ploughing and weeding work will be carried out at the beginning of the year. Prevent excessive weeds from grabbing the nutrients needed for the growth of bracken, and ploughing and weeding regularly for the next year. It can only improve the permeability of the soil, promote the absorption of nutrients in the roots, and concentrate the nutrients on bracken. Then we should do a good job in water and fertilizer work, properly apply farm manure, reduce or stop the use of pesticides and chemical fertilizers, improve the quality of bracken, and promote the formation of pollution-free green food.

4. Fourth year management

In fact, the management in the fourth year is similar to that in the third year, because by this time bracken is almost ready to be picked. It should be noted that, in order to prevent the occurrence of grass famine, we have to weed about 4 times, reduce the number of weeds in the field, it is best to be weed-free. During its growing period, the main weeding object is to pull out those tall weeds, so as to avoid having a great impact on the growth of bracken. Then when it withered in autumn, the plant was broken and spread as a weed on the soil to keep warm. Finally, we should pay attention to pulling out the plant of diseases and insect pests, and then take it out of the countryside and do burning treatment.

The above is a brief introduction to the main points of field management of bracken. The growth cycle of bracken is very long, and it can be harvested for almost 10 years at a time. It is generally harvested in spring and summer every year, and it must not be harvested too late, which will not only reduce the value of commodities, but also affect the output in the coming year. This is the end of today's introduction, this article is for reference only, I hope it can be helpful to everyone!
