Weaving method: plain weave, plain dutch weave, twill weave, dutch twilled weave
1. Plain Weave: also called tabby weave, linen weav or taffeta weave, is the most basic type of weaves. In plain weave, the warp and weft are aligned so they form a simple criss-cross pattern. Each weft thread crosses the warp threads by going over one, then under the next, and so on. The next weft thread goes under the warp threads that its neighbor went over, and vice versa.
2. Twill Weave: In a twill weave, each weft or filling yarn floats across the warp yarns in a progression of interlaces to the right or left, forming a distinct diagonal line. This diagonal line is also known as a wale. A float is the portion of a yarn that crosses over two or more yarns from the opposite direction.
3. Plain Dutch Weave: similar with plain weave, just the weft and warp wire have different wire diameter and different mesh size.
4. Twill Dutch Weave: similar with twill weave, just the weft and warp wire have different wire diameter and different mesh size.
5. Reversed Dutch Weave: difference from standard Dutch weave lies in the thicker warp wires and less weft wires.

[China Agricultural Machinery Industry News] By the end of 2015, China has developed an effective irrigated area of ​​988 million mu of farmland. The grain produced on this part of the land accounts for about 75% of the country's total output, and economic crops account for more than 90%. Although China's farmland water conservancy development has achieved great results, compared with the requirements of developing modern agriculture and ensuring national food security and supporting farmers' income increase, there are still many gaps, inadequate irrigation and drainage facilities, unsupported, aging, and low standards. The problem still exists, the project construction is out of line, the management methods are backward, and the lag of farmland water conservancy construction is still a major constraint on the stable development of agriculture and national food security.
Constructing farmland water conservancy support system to fill the shortcomings of modern agricultural development
The primary task of modern agriculture is to ensure national food security, and irrigation and drainage projects are important infrastructure. Good irrigation and drainage infrastructure conditions are necessary to resist natural disasters, significantly reduce agricultural costs, and improve agricultural production efficiency. Irrigation and drainage can meet the requirements of crop diversification, especially for high value-added crops, in order to meet the requirements of increasing crop multiple cropping index, and there is a greater room for manoeuvre in agricultural restructuring. To implement the "National Agricultural Modernization Plan (2016-2020)", we must promote the construction of farmland water conservancy and accelerate the irrigation of farmland water conservancy in accordance with the water conservancy work guidelines of "priority-saving, space-balance, system governance, and two-handed efforts" in the new period of the central government. The reform of infrastructure modernization and management system and mechanism, focusing on building a farmland water conservancy support system with good engineering, water use, sound system and flexible mechanism to fill the shortcomings of modern agricultural development.
Accelerate the construction of a complete and complete irrigation and drainage engineering system. By 2020, it is necessary to basically complete the tasks of large-scale irrigation districts, key medium-sized irrigation districts for continuous construction and water-saving renovation, and implement modernization of large and medium-sized irrigation districts. In combination with the national plan to increase the production capacity of 100 billion kilograms of grain, a new batch of irrigation districts will be built in areas where water and soil resources are available, and the effective irrigation area of ​​farmland will be increased by about 30 million mu. Complete the renovation and renovation of large and medium-sized irrigation and drainage pumping stations, strengthen the management of serious areas with waterlogging disasters, and improve the irrigation and drainage system. Strengthen the field project support for large and medium-sized irrigation districts, and promote the construction of high-standard farmland for drought and flood control. Accelerate the construction of small and medium-sized farmland water conservancy projects, combine poverty alleviation, and give priority to supporting the construction of “small small water conservancy projects†such as the old revolutionary areas, ethnic areas, border areas, poverty-stricken areas, small water pools, small pools, Xiaotangba, small pumping stations, small water channels, etc. Combined with the adjustment of agricultural planting structure, strengthen the construction of water source projects and improve irrigation and drainage conditions.
Vigorously develop water-saving irrigation. In the past 20 years, under the condition that the total amount of irrigation water has not increased, the effective irrigated area has increased by 230 million mu, and the irrigation guarantee rate has increased remarkably, mainly relying on water-saving reform in irrigation districts and large-scale development of water-saving irrigation. In the next few years, the need to increase the effective irrigated area and increase the irrigation guarantee rate, thereby improving the comprehensive agricultural production capacity and meeting the crop planting structure adjustment and increasing the multiple cropping index, requires the addition of irrigation water. While accelerating the pace of water-saving renovation of irrigation and drainage engineering facilities in large and medium-sized irrigation areas, appropriate water-saving irrigation techniques and measures should be adopted according to local conditions, and concentrated and large-scale promotion festivals should be carried out in water shortage areas, ecologically fragile areas and major grain producing areas. Water irrigation technology. The northwestern region and the hilly area should combine poverty alleviation and develop small and small water-saving irrigation systems according to local conditions. During the “Thirteenth Five-Year Plan†period, 140 million mu of water-saving irrigation projects will be added, including water-saving irrigation area of ​​100 million mu; the effective utilization rate of farmland irrigation water will be increased to 0.55 or more, and the total irrigation water for farmland will be controlled at 372 billion cubic meters. Within. Through vigorously developing water-saving irrigation technologies such as sprinkler irrigation and micro-irrigation, it will significantly improve labor productivity, promote the management of “water and fertilizer integrationâ€, and provide strong support for promoting moderate scale operation of agriculture and promoting reform of agricultural supply side.
Deepen the reform of farmland water conservancy management system. Actively expand the channels for inputting farmland water conservancy and establish a multi-investment mechanism for farmland water conservancy. Vigorously promote the reform of the property rights system of small-scale farmland water conservancy facilities, and effectively implement the management main body and management and protection measures. We will deepen the comprehensive reform of agricultural water prices, combine engineering reform, management system reform and water price reform, first build mechanisms and post-construction projects, and fully mobilize the enthusiasm of village collectives and farmers' water cooperation organizations. Strengthen the capacity building of farmers' water cooperation organizations, and encourage farmers' water cooperation organizations to cooperate or integrate with farmers' professional cooperatives. Strengthen the construction of professional management team, strive to improve the management level, and adapt to the requirements of agricultural modernization development for water conservancy project management as soon as possible. Establish a working mechanism for the positive interaction between water conservancy and agriculture, an incentive mechanism for water use, and cultivate planters and farmers' water cooperative organizations to become the leaders in the promotion of water-saving irrigation technology. Strengthen the scientific management of irrigation water, strictly control the total amount of irrigation water resources, and manage the quotas, gradually improve the irrigation water measurement system, strengthen the irrigation water consumption and irrigation water quality monitoring capacity, promote the sustainable use of water resources, and ensure the modernization of agriculture.
