Problems solved by technology

But the problem is that the traditional ramie harvesting mode is three seasons a year, and the harvesting time is basically in June, August and early to mid-October, and there is no raw material supply to the factory at other times, which will undoubtedly increase the operating cost of the factory and make the original ramie harvest. It is hoped that the idea of ​​stripping fibers in a factory will become empty talk

Embodiment 1

[0016] A method for uninterrupted harvesting of ramie fibers, the steps are:

[0017] A. The selected ramie variety is Huazhu No. 4, and the experimental site is the experimental base of Huazhong Agricultural University. The ramie garden was divided into 5 blocks, and the traditional harvesting mode was used as a control, with 3 repetitions. In April 2008, the seedlings were propagated through shoot tip cloning, and the seedlings with consistent growth were selected and transplanted to the field in September. In 2008-2009, the conventional management measures were used in the field, and in 2010, the experiment was carried out with Trillium hemp. The base fertilizer application standard is N 225kg / hm 2 , P 150kg / hm 2 , K 300kg / hm 2 .

[0018] B. Harvest early. Plot 1 was harvested on May 28th, July 9th, August 14th and September 17th, and the harvested fresh stem weight was 59438.04kg / hm 2 , 37.25% more than the control, fresh skin yield 22202.76kg / hm 2 , 34.05% more th...

Abstract

The invention discloses a method for continuously harvesting ramie fibers, which comprises the following steps of: A. ramie plantation segmentation: the planted ramie is harvested in different areas in different time periods, the area of a ramie plantation is divided into blocks according to the standard of harvesting 1-10 days / block, and by utilizing the natural condition with sufficient rainfall and sunlight in June-September, the continuous harvest in May-October in each year can be realized; B. early harvesting: the time is five-twenty days earlier than the normal harvesting time; C. additionally fertilizing: after the ramie fibers are harvested, a nitrogenous fertilizer is applied according to a N60-80kg / hm2 standard; and D. culturing and managing in winter: the culture and the management are strengthened in winter, and a cake fertilizer (1,000-1,500kg / hm2) and NPK compound-fertilizers (600-80kg / hm2) are applied again.

Description

technical field [0001] The invention belongs to the technical field of high-yield and high-efficiency cultivation of ramie, and more specifically relates to a method for uninterrupted harvesting of ramie fibers. Background technique [0002] Ramie is a perennial bast fiber crop of Urticaceae (Urticaceae) genus Bochmeria, which originated in China and is called "Chinese grass" by Westerners. As one of the important raw material crops of textile industry in China, ramie has excellent fiber quality and plays an important role in textile industry, and has attracted more and more attention from the government and scientific and technological workers. At present, China's ramie planting area is about 100,000 hectares, and its output accounts for about 90% of the world's total output. [0003] With the development of China's market economy, a large number of rural laborers have transferred to cities, resulting in higher and higher labor costs for traditional crop cultivation models...
