背景技术 Background technique
众所周知，我国是一个干旱缺水严重的国家。淡水资源总量为28000亿立方米，占全球水资源总量的6%，仅次于巴西、俄罗斯和加拿大，居世界第四位，但人均只有2200立方米，仅为世界平均水平的1／4、美国的1／5，在世界上名列121位，是全球13个人均水资源最贫乏的国家之一。我国又是一个农业大国，农业的用水量占了我国总用水量的90%，但目前全国灌溉用水效率普遍较低，70%的农田处于严重缺水状态。 As we all know, my country is a country with severe drought and water shortage. The total amount of fresh water resources is 2,800 billion cubic meters, accounting for 6% of the total global water resources, ranking fourth in the world after Brazil, Russia and Canada, but the per capita is only 2,200 cubic meters, only 1/2 of the world's average level 4. One-fifth of the United States ranks 121st in the world, and it is one of the 13 countries with the poorest per capita water resources in the world. my country is also a large agricultural country, and agricultural water consumption accounts for 90% of my country's total water consumption. However, the current national irrigation water efficiency is generally low, and 70% of farmland is in a state of severe water shortage.
水肥一体化技术是将灌溉与施肥融为一体的农业新技术。水肥一体化是借助压力系统（或地形自然落差），将可溶性固体或液体肥料，按土壤养分含量和作物种类的需肥规律和特点，配兑成的肥液与灌溉水一起，通过可控管道系统供水、供肥，使水肥相融后，通过管道和滴头形成滴灌、均匀、定时、定量，浸润作物根系发育生长区域，使主要根系土壤始终保持疏松和适宜的含水量，同时根据不同的蔬菜的需肥特点，土壤环境和养分含量状况；蔬菜不同生长期需水，需肥规律情况进行不同生育期的需求设计，把水分、养分定时定量，按比例直接提供给作物。现在常用的水肥一体化采用灌溉方式，有喷灌和微观等形式，目前常用形式是微灌与施肥的结合，且以滴灌、微喷与施肥结合的居多，但是这些方式都存在水压低，水量大，肥料和水源浪费巨大的问题，因此，其改进和创新势在必行。 Water and fertilizer integration technology is a new agricultural technology that integrates irrigation and fertilization. The integration of water and fertilizer is to use the pressure system (or the natural drop of the terrain) to mix the soluble solid or liquid fertilizer according to the soil nutrient content and the law and characteristics of the fertilizer demand of the crop species, and the fertilizer solution is mixed with the irrigation water through the controllable pipeline. The system supplies water and fertilizer. After the water and fertilizer are mixed together, drip irrigation is formed through pipes and drippers, evenly, regularly, and quantitatively, infiltrating the growth area of the root system of the crops, so that the main root system soil is always kept loose and suitable for water content. At the same time, according to different Vegetables need fertilizer characteristics, soil environment and nutrient content; vegetables need water in different growth periods, and the law of fertilizer needs is designed according to the needs of different growth periods, and the water and nutrients are regularly and quantitatively provided to crops directly in proportion. Now the commonly used water and fertilizer integration adopts irrigation methods, including sprinkler irrigation and microscopic forms. At present, the commonly used form is the combination of micro-irrigation and fertilization, and the combination of drip irrigation, micro-spray and fertilization is the majority, but these methods have low water pressure and large water volume. , huge waste of fertilizer and water, therefore, its improvement and innovation is imperative.
