| 滴灌带使用 Use of drip irrigation belt 一.滴灌的管道和滴头容易堵塞，对水质要求较高，所以必须安装过滤器; First, drip irrigation pipelines and drippers are easy to clog and require high water quality, so filters must be installed. 二.滴灌不能调节田间小气候，不适宜结冻期灌溉，在蔬菜灌溉中不能利用滴灌系统追施粪肥。 2. Drip irrigation can not regulate the microclimate in the field, and it is not suitable for irrigation during freezing period. In vegetable irrigation, drip irrigation system can not be used to topdress manure. 三.滴灌投资较高，要考虑作物的经济效益; 3. The investment of drip irrigation is relatively high, and the economic benefits of crops should be considered. 四.滴灌带的灼伤 注意在铺设滴灌带时压紧压实地膜，使地膜尽量贴近滴灌带，地膜和滴灌带之间不要产生空间。避免阳光通过水滴形成的聚焦。播种前要平整土地，减少土地多坑多洼现象。防止土块杂石杂草托起地膜，造成水汽在地膜下积水形成透镜效应，灼伤滴灌带。铺设时可将滴灌带进行潜埋，避免叫焦点灼伤。 Fourth, pay attention to the burns of drip irrigation belts, when laying drip irrigation belts, compact film should be compacted to make the film as close as possible to the drip irrigation belts, and there should be no space between the film and the drip irrigation belts. Avoid focusing sunlight through water droplets. Before sowing, the land should be leveled to reduce the phenomenon of multiple pits and depressions. Prevent soil weeds from lifting plastic film, causing water vapor to accumulate under the film to form lens effect and burn drip irrigation belt. When laying, drip irrigation belt can be buried to avoid calling focus burns. |
