Planting techniques of Ramie

Ramie is one of the important fiber crops in ancient times. It has been cultivated for more than 4,000 years in China. It was mainly used to make linen and fine hemp rope in ancient times. With the progress of society, these items are constantly eliminated, but later found that the protein content of ramie leaves is relatively high, so it is often used to make feed. In addition, its roots contain ramie acid medicinal ingredients, which have the effects of nourishing yin and preventing abortion. It is also widely used in medicine, papermaking raw materials and chemical raw materials. It has a wide range of uses and good planting prospects, so how should it be planted? Let's take a look at the pro-farming network together.

1. Choosing land to build gardens

Ramie is a warm-loving short-day plant, which is more suitable for planting in temperate and subtropical climate, so it is best to choose leeward sunny and well-drained areas for planting, but the intensity of light should not be too strong, and the low water level should not be planted below 1 meter. It can adapt to sandy to clay soils, but grows best in loose soils.

2. Sowing seedlings

Ramie propagation methods are numerous, common root propagation, but at that time there are perennial old plants as the premise, just planted or choose sowing propagation method. The sowing time is from early March to early April. Select market conditions as seedbed, apply sufficient base fertilizer, rake fine and level, and then sow. Generally, the germination rate of sowing is 30%, and the sowing amount per mu is about 1 jin. When sowing, seed dressing and sowing are carried out with fine mud or plant ash. Water is poured once before sowing. After sowing, a layer of fine soil and plant ash is covered, and then a layer of straw and crop straw is covered on it to keep warm and moist. After sowing, keep the soil moist. After emergence, gradually remove the mulch as the seedlings grow. When the seedlings grow 6 true leaves, they can be completely removed.

3. Thinning and weeding

Thinning seedlings in time at seedling stage can make seedlings grow quickly and improve yield. Generally, thinning seedlings once during 4 leaves and thinning seedlings for the second time during 6 leaves can be carried out. The plant spacing is 4-5cm. 400-500 plants can be planted per square meter. At the same time of thinning seedlings, diseased plants and weak seedlings can be removed, weeds can be removed, pesticides can be sprayed to prevent diseases and pests, during this period, there are 1-2 times of intertillage, timely loosening, once in the germination period, shallow tillage to assist budding, so that the buds are neat, and there is a layer in the sealing period, intertillage 4-5cm.

4. Fertilizer and water management

After the mulch is removed, it should be watered frequently to keep the soil moist. At the 3-4 leaf stage, it can be combined with watering and appropriate fertilization. At this time, some urine fertilizer can be applied in an appropriate amount, once a week, 2-3 times. When the seedlings grow to about 20cm, it is necessary to apply seedling fertilizer to promote rapid growth of seedlings. When about 60cm, pay attention to one-time stalk fertilizer. The fertilizer is generally based on human and animal manure, cake fertilizer or urea. Generally, 1000kg of farm manure, 100kg of cake fertilizer and 20kg of urea are applied per mu. In the peak season, a small amount of boron fertilizer can be applied to increase yield.

5. Harvest

Ramie is a crop that has been harvested many times. The first harvest is in late May or early June, and the first harvest is early, which promotes the early development of the second hemp. After harvest, repeat the above work. The same thinning weeding, fertilizer and water management, two hemp is generally in late July, after harvest intertillage, weeding and fertilization, but also pay attention to the prevention and control of diseases and insect pests, promote the healthy growth of three hemp. Three hemp growth season in late summer and early autumn, disease is more serious, climate change is greater, in addition to pests, but also summer drought and autumn drought and flood control measures, three hemp generally in late October or early November can be harvested.

The above is the planting technology of ramie brought by the pro-agricultural network. I hope it can help you. If you want to know more, please pay attention to the pro-agricultural network.
