Problems solved by technology

At present, it is found that jute has a new application of absorbing heavy metal ions in wastewater. However, this new application needs to use jute whole stems (including stems and leaves) as raw materials, and the yield of jute whole stems is relatively high, and the dry matter output can reach 21t / hm 2 , the output of fresh stems and leaves reaches 190t / hm 2 , causing great problems for drying
First of all, the drying time is long, the water content of fresh jute stalks reaches 85-90%, the outer layer wraps the phloem, which is not conducive to water evaporation, and the drying time needs 35-45 days; secondly, the later stage of drying is sensitive to moisture, and it is easy to turn black when exposed to dew , mildew

Embodiment 1

[0018] In a place in Hunan, three drying methods were used to test, and each method was tested with 10 tons of jute fresh stems and leaves. The result is as follows:

[0019] The first one is to dry according to the steps in the method of the present invention. After the jute is harvested, the leaves are cut off slightly, and taken to dry on the concrete floor. At that time, the average daytime temperature is 26°C, and the drying period reaches the standard of 14% water content after 16 days. It rained for 2 days during the period, and some parts were able to be sun-dried freely. The leaves did not encounter rain, and no mildew or loss occurred.

[0020] In terms of drying the lower part of the stems, cut off the stems and lay them flat, evenly spread them on the planting ground to dry for 7 days, tie the top of the stems when the water content reaches 60%, and stand in the field to continue drying for 14 days, until the water content drops to 16%. , transfer it to the stack...

Embodiment 2

[0028] In another place in Hunan, according to the steps in the method of the present invention, carry out 3 years of production and application. In the first year, after the jute is harvested, the leaves are slightly cut off, and the water content reaches 13% after drying on the cement floor for 18 days. After cutting off the stems, place them flat and spread them evenly on the planting ground to dry for 12 days. When the water content reaches 75%, tie up the top of the stems and stand in the field for 23 days. When the water content drops to 16%, transfer them to Stacks under the eaves. In the second year, after the jute was harvested, the leaves were slightly cut off, and the water content reached 13% after drying on the cement floor for 16 days. After cutting off the stems, place them flat and spread them evenly on the planting ground to dry for 11 days. When the water content reaches 55%, tie up the top of the stems and stand in the field for 21 days. When the water cont...

Abstract

A treatment method for preventing jute from mildew includes the steps: S1, harvesting the jute, and separating tops with leaves from stems; S2, placing the tops with the leaves on a cement floor to dry for 16-18 days; S3, uniformly spreading the stems on a planting site to dry for 7-12 days, binding the tops of the stems when the surfaces of the stems are yellow green, and erecting the bound stems on a field to continue to dry for 14-23 days; S4, transferring the stems to an eave to stack when the water content of the stems is reduced to 16-17%, and paying attention to prevent rain and humidity, ventilate and breathe. The tops with leaves and the stems are separated to dry, the dried jute is excellent in quality, indexes such as a drying period, a drying effect and rotting rate can stably reach quality standards under the conditions of different years and different climates, and the dried jute has the advantages that the water content can reach a standard, and the dried jute is fine in color and low in rotting rate.

Description

【Technical field】 [0001] The invention belongs to the field of agricultural production, and in particular relates to a treatment method for preventing jute from going moldy. 【Background technique】 [0002] The fibers of jute are mainly used in textiles, packaging and other fields. In terms of production and planting, the technology is relatively mature, and the fiber output is generally 2800-3600kg / hm 2 , There is no technical difficulty in the drying process of the fiber. At present, it is found that jute has a new application of absorbing heavy metal ions in wastewater. However, this new application needs to use jute whole stems (including stems and leaves) as raw materials, and the yield of jute whole stems is relatively high, and the dry matter output can reach 21t / hm 2 , the output of fresh stems and leaves reaches 190t / hm 2 , which brings great problems to drying. First of all, the drying time is long, the water content of fresh jute stalks reaches 85-90%, the oute...
