What material is the American ginseng curtain made of? How to weave curtains?

Ginseng curtain can be made of reed, Artemisia stalk, corn stalk, sorghum stalk, rice straw, bamboo bark and wood strips. Ginseng curtains made of bamboo and wood strips have more regular and uniform light transmittance, but the cost is higher. Artemisia stalk, corn stalk, sorghum stalk and rice stalk are easy to get and have low cost, but they are not durable. From the national perspective, reed is the most widely used. Because of its wide distribution, it is distributed on both sides of beaches, lakes and streams. Convenient materials, low price and easy curtain weaving. Curtains are usually made of thin iron wire or nylon rope at certain intervals. The size and specification of curtains should depend on the type of shed used and the appropriate local light transmittance. The roofs of small sheds and low sheds are generally 2.0 meters wide and 2.5 ~ 3.0 meters long, while the roofs of high sheds are generally 2.0 meters wide and 5.0 meters long. Single-transparent shed is a plastic film sandwiched between two curtains, which only transmits light and is not rainproof, so the curtains have a large gap. For example, for a reed curtain, the diameter of reed bundles is 3 cm, and the gap between bundles is 5 cm. As a lower curtain, it is covered with a layer of PVC plastic film, and the light transmittance is about 20%. If it is sunny in July and the temperature rises, it is necessary to reduce the light transmittance and add a layer of 65438+ gap on it. If you use a double-shed, generally only one curtain is used, and the curtain should be made denser, so that American ginseng will not be hurt under the condition of high temperature and strong light in summer, but it should not be too dense, which will seriously affect the yield of American ginseng in spring and autumn. Therefore, when making curtains, the thinness and density of curtains should be determined according to the best light intensity of local American ginseng.

Weaving method of reed curtain: If the curtain is about 2m wide, the four paths of the curtain should be made of thin iron wire or nylon rope. When making curtains, two people should hold a frame, with two lines in each frame. At the same time, curtain (reed bundle) should be made well, with the roots facing outwards and tip to tip, and a handful of reed grass should be beaten for 3-5 times (according to the gap size of reed bundle) until it is finished. Using bamboo strips, bamboo chips, wormwood stalks and wooden strips as curtains, the operation method is the same, but the bamboo strips and wormwood stalks are thinner, and the gap is correspondingly smaller when weaving.
