Keywords: pollution-free vegetables cultivation technique standard requirements

无公害蔬菜是严格按照无公害蔬菜生产安全标准和栽培技术生产的无污染、安全、优质、营养型蔬菜，并且，蔬菜中农药残留、重金属、硝酸盐、亚硝酸盐及其它对人体有毒、有害物质的含量控制在法定允许限量之内，要符合有关标准规定。

Pollution-free vegetables are in strict accordance with the pollution-free vegetable production safety standards and the production of pollution-free cultivation techniques, safety, high quality, nutritional vegetable, and vegetable pesticide residues,

heavy metals, nitrate, nitrite and other poisonous and harmful substances to human body content of control within the legal allowed limits, to comply with relevant standards.

一、无公害蔬菜栽培技术

A, pollution-free vegetables cultivation techniques

发展无公害蔬菜，重点是把好生产基地选择与改善、种植过程无害化、蔬菜残留毒物检测“三关”，抓好产地环境、品种选用、培育壮苗、健身栽培、病虫防治、质量检测“六大环节”。总的来说就是采取无公害蔬菜生产技术措施，使基地环境、生产过程和产品质量达到无公害标准要求。

Development of pollution-free vegetables, the key is to put the good selection and improve production base, planting process innocuity, vegetable residue toxicology testing "three close", pays special attention to the environmental, variety selection, cultivation of seedling, health cultivation, pest management, quality inspection "six big link". In general is pollution-free vegetable production technology measures, the base environment, production process and product quality reached the standard requirements.

二、大田种植与管理

Second, planting and management field

1、根据土壤类型不同，种植不同种类的蔬菜。

2、精细整地。

3、定

植。根据不同品种要求，合理密植。4、中耕、除草、培土。5、搭架、整枝、疏果。6、小拱棚、大棚温湿度管理。

1, according to different soil type, plant different kinds of vegetables. 2, fine soil preparation. 3, engraftment. In accordance with the requirements of different varieties, reasonable density. 4, cultivating, weeding, soil. 5, a big, pruning, fruit thinning. 6, small GongPeng, greenhouse temperature and humidity management.

三、灌溉基本原则与方法

Three, the basic principle and method of irrigation

1、基本原则

1, the basic principles

（1）沙土壤经常灌，粘壤土要深沟排水。低洼地“小水勤浇”，“排水防涝”。（2）看天看苗灌溉。晴天、热天多灌，阴天、冷天少灌或不灌，叶片中午不萎蔫的不灌，轻度萎蔫的少灌，反之要多灌。暑夏浇水必须在早晨九点前或傍晚五点之后进行，避免中午浇水。若暑夏中午下小雷阵雨，要立即进行（版权声明：本文转载自论文网在线()，版权归原作者所有。）灌水。（3）根据不同蔬菜及生长期需水量不同进行灌溉。

(1) often fill sand soil, clay loam to ditch drainage. Low-lying land "num frequently pouring", "drains". (2) days look at seedling irrigation. Sunny, hot weather more, cloudy, cold day less or no irrigation, blade not wilting at noon. It's filling and mild wilting less
