How to prevent freezing when planting baiji in winter, and the planting conditions of baiji

Mulching is usually used to keep the plant safe for the winter.

Baiji prefers warm, humid environments. In early December, the stems and leaves of Baiji senesce, gradually wither, and the roots enter the hibernation period, at this time, the weeds and diseased plants inside and outside the garden should be removed and discarded outside the garden. If you find exposed roots or tubers on the furrow, they should be covered with fine soil.

Baiji is not cold-tolerant, and should be done to prevent cold and ice in winter, cover the grass to prevent cold, and remove the cover grass when the seedlings emerge in spring (if the seedlings can grow normally, they can also not be removed).

Measures that can be taken for wintering protection are:

1. Cover the pine leaves:

In winter, when all the above-ground plants die, remove weeds and diseased plants inside and outside the garden, cover a layer of dry pine leaves on top, keep warm in winter and moisturize in summer. There are pine trees in most areas of Yunnan, and it is okay to mix with the fallen leaves of other trees in the general mixed forest zone.

2. Cover hay:

General weeds are collected and dried and then chopped and covered.

3. Cover the rotted manure:

After the garden is cleaned, a layer of rotted manure is applied, and about 1,000 kg per mu is applied, which not only keeps warm and frost but also provides nutrients. If there are dry pine leaves or hay, cover them with another layer to ensure that the buds are safe to overwinter. (Manure:

Livestock manure, gasket material, feed residue mixed and accumulated and microbial action to form fertilizer. ）

4. Cover straw:

Wheat, rice, corn and other crops are dried and chopped after harvesting. Straw mulching reduces the ground evaporation of soil water during the drought period and maintains the water storage of the cultivated layer. The rainy season buffers the erosion of soil by heavy rains, reduces surface runoff, and increases the water storage of cultivated layers. The mulching straw isolates the direct sunlight on the soil, and plays a role in regulating the exchange of soil and surface warmth.

In addition, mulching straw also has a good effect on inhibiting the growth of weeds.

The planting conditions of Baiji include: the soil should be highly permeable; The light should not be too strong, the maximum temperature should not exceed 30 degrees, and the minimum should not be lower than 10 degrees; Do not apply fertilizer indiscriminately, etc.

nbsp;Baiqi is a kind of Chinese medicinal material, ** reported the news of planting Baiqi in a certain place to get rich, which attracted the attention of many people. Many people want to know what are the planting conditions of Baiji? Let's find out.

Details:

Soil requirements. The planting land should choose a sandy loam soil with loose soil, sufficient fertility, rich in organic matter and humus, and the clay soil is not suitable for planting Baiji.

Lighting requirements. It likes shade, has strong resistance to negativity, and is afraid of strong light, so light conditions are an important factor in the planting of Baiji, if the light in the planting area is too strong, it is necessary to build a shade shed for shade.

Temperature requirements. It is more suitable for growing in a warm environment, and the temperature of the planting area should not exceed 30 degrees, and the minimum should not be lower than 10 degrees.

Water and fertilizer requirements. Baiji has a large demand for water and fertilizer, but the requirements for fertilizer and water are stricter, and nitrogen fertilizer, potassium fertilizer, phosphate fertilizer, etc. can not be applied in the process of planting.

In the planting of Baiji, it is necessary to pay attention to grasp the planting environment and planting technology. If both meet the requirements of Baiji cultivation, then there is no difficulty in planting Baiji.

When planting baiji, you need to choose loose and fertile humus or sandy soil. 3. Planting: Sprinkle the seeds of Baiji on the soil and cover 1-2 cm of sandy soil.

4. Prevention and control of pests and diseases: timely uproot the infected Baiji seedlings and spray fungicides.

1. Suitable environment

The environment for planting Baiji should be relatively humid, but warm enough, Baiji has a negative tolerance, but is afraid of strong light. Therefore, you can choose a darker environment for planting to ensure the humidity of the environment, avoid direct sunlight in summer, and prevent the leaves from drying out.

2. Suitable for soil

When planting Rhizome, you should choose the soil that is rich in nutrients and has good drainage, and you can choose humus soil with more humus or loose and nutrient-rich sandy loam soil for planting.

3. Reproduction

It is usually propagated by dividing plants. When harvesting Baiji, choose the germination of the top bud of Baiji as a branch, planting in the coming year, generally an old plant can germinate three to four branches, pay attention to the supply of nutrients when planting, try to fertilize as many times, and weeding regularly.

4. Pests and diseases

In the process of growth, we should pay attention to the prevention and control of pests and diseases, generally when planting, it is easy to get root rot, so in the season of too much rain, we should pay attention to dredging water to Baiji, so as not to cause water to cause rot roots, and pest control only needs to be sprayed with insecticides regularly.
