"You see, a screw valve, entire grape drink base 'water'." 27, after the street in the Yongsan Lee Yeung Village, 30 acres of grapes relaxed base, the reporterBall Valves
saw the venue management to total valve counterclockwise a rotation, fertilizer and water along the UPVC pipe to flow instantly PE dropper, spray irrigation of grape. "In the Longshan streets, a total of 800 acres of grapes to achieve this model of field management." Then the manager told reporters.
According to reports, mechanized irrigation measures grape planting base is mainly planted in the main branch to the Tiankuai UPVC pipe,
The Tiankuai layout layout dropper according to the grape growing, connecting the main branch pipe, and then use the pool pump pumping to the fertilizer, to fertilizer ratio, then high-pressure pump through the main branch pipeline to the dropper around the block, for Rotation differentAutomatic Control Valves
varieties, land control by the valve itself.
"In the past, Longshan street planting grapes spite of the cultivation, but basically the main extensive management, flood irrigation, pesticide application over phenomena occur. In recent years as people's living standards, quality requirements for agricultural products increasing, the traditional production management have been behind the quality requirements, and the high cost of extensive management, makes the product quality and price in losing our edge. In view of Ci, the streets ofCheck Valves
grapes from Quniankaishi pilot Ying Yong Gao Xiao water Guangai technology, this large spread. "Longshan street party members Duo Xie told reporters.
It is understood that after the technology is mainly used in foreign and Example grape base, involving three of the 36 grower cooperatives, total invested 100 million yuan.
It is understood that the application of irrigation, promotion of the grape growth, improve grape quality and increase farmers income and social benefits are obvious. Disease significantly reduced efficiency of the section marked. "The original artificial irrigation, artificial fertilization and other sectors to reduce, the majority of fertilizer is also implemented by dropper, fertilizerSafety Valves
also reduces waste and weeds have been controlled, labor, fertilizers, and can save 300 yuan per mu; In addition, after the use of drip irrigation , grape disease reduction, grapes grow well and fruit quality has been significantly improved, the top grade fruit rate increase of 10%, 202 yuan per mu yield efficiency. "Xie Duo introduces Road. At the same time, also reduce the agricultural non-point source pollution, fertilizer and water management as fertilizer by fertilizer, fertilizer using the grapes to ensure the growth of nutrient requirement, not to cause unnecessary loss of fertilizer to Instrumentation Ball Valves
minimize the agricultural nonpoint source pollution. Water clear. According to the growth of grapes in different cycles, to be drip irrigation, saving water resources, compared to the original use of the flood irrigation method could save water seven cubic meters per mu.

译文：管理人员对总阀门逆时针一旋，肥水顷刻沿着UPVC管流到PE滴管
“你看，阀门一拧，整片葡萄基地喝上了‘自来水’。”27日，在闸阀
龙山街道后洋村李轻松的30亩葡萄基地，记者看到场地管理人员对总阀门逆时针一旋，肥水顷刻沿着UPVC管流到PE滴管，对葡萄进行喷雾滴灌。“在整个龙山街道，共有800亩葡萄实现了这种模式的田间管理。”该管理人员接着对记者说。
据介绍，机械化灌溉葡萄的措施主要是在种植基地埋设主支UPVC管到各田块，
各田块根据葡萄种植布局布置滴管，连接主支管道，然后利用泵站抽水到肥水池，进行肥水配比，再由高压泵站经主支管道输送到各地块的滴管，进行轮灌，不同的品种、地块由各阀门自行进行控制。
“以前，龙山街道种植葡萄尽管采取了设施栽培，但截止阀
基本上以粗放式管理为主，大水漫灌、施药过度现象时有发生。近年来随着人们生活水平的提高，对农产品的品质要求越来越高，传统的生产管理已经跟不上品质的要求，而且粗放型管理的成本高，使得产品在品质与价格方面失去优势。鉴于此，该街道从去年开始试点应用葡萄高效节水灌溉技术，今年大面积铺开。”龙山街道党委委员谢铎对记者说道。
据了解，该技术主要应用于后洋和渚山葡萄基地，涉及三个合作社的36户种植大户，总投入100多万元。
据了解，该灌溉应用，促进了葡萄生长，改善了葡萄品质，增加止回阀
种植户收入，并且社会效益明显。病害明显减少，节本增效明显。“原本人工灌水，人工施肥等环节减少，大部分施肥也通过滴管实施，肥料也减少了浪费，杂草也得到了控制，人工费、肥料等每亩可节省 300元；另外，采用滴灌后，葡萄的病害减少，葡萄生长良好，果实的品质有了明显提高，上品果率可增加10%，每亩增产增效202元。”谢铎蝶阀
介绍道。与此同时，还减少农业面源污染，由于施肥通过肥水管理进行施肥，用肥量保证了葡萄生长的需肥量，不造成多余肥料流失，从而最大程度减少了农业面源污染。节水明显。根据葡萄柱塞阀
的生长不同周期，进行定滴灌，节约了水资源，相比安全阀
原来采用大水漫灌的方式，每亩可节水7立方米。
