喷灌系统规划设计的内容一般包括:勘测调查,喷灌系统选型和田间规划以及水力计算和结构设计三个步骤: 一、喷灌地区的勘测调查为了要设计一个喷灌系统首先要在灌区范围内进行调查,收集地形、气象、土壤、水文、农作、动力机械、行政区划、经济规划等有关资料。并进行实地踏勘取得第一性的材料。如果地形,土壤等必要的资料不足,还要予先进行测量,实地观测等工作。为要进行喷灌系统设计所必须的基本资料有以下几类。 (一)地形资料:最好能获得全灌区1/500～1/2000的地形图,地形图上应有灌
Sprinkler irrigation system planning and design content generally includes: survey and survey, sprinkler system selection and field planning and hydraulic calculation and structural design of the three steps: First, the sprinkler survey survey area In order to design a sprinkler system must first be investigated within the irrigation area , Collecting topographic, meteorological, soil, hydrology, farming, power machinery, administrative divisions, economic planning and other relevant information. And conduct field visits to obtain first-class materials. If the terrain, soil and other necessary information is not enough, but also to carry out measurements, field observations and other work. The basic information necessary for sprinkler system design is as follows. (I) Topographical data: It is best to obtain topographic maps of 1/500 ~ 1/2000 of the whole irrigation area, topographical maps should have irrigation
