| 2. | Research on low - head drip irrigation system 低压滴灌系统研究 |
| 3. | Guidelines for plugging hazards of drip irrigation systems are presented ( table11 ) 表11给出了滴灌系统形成阻塞的一些水质指标。 |
| 4. | In india , a small company makes and sells low - cost drip irrigation systems to poor farmers 在印度,有一家小公司制造并销售低成本的滴灌系统给家境贫困的农民。 |
| 5. | This can conserve lots of labor . irrigation uniformity is used as weighing the quality of drip system 滴灌系统的灌水均匀度是衡量滴灌系统灌水质量的一个重要指标。 |
| 6. | Low pressure trickle irrigation is based on the little effect of pressure on the quality of drip irrigation system 压力水头对滴灌系统的灌水质量影响很小,这为低水头滴灌提供了理论依据。 |
| 7. | The increase has been especially dramatic during the past two decades in the u . s , particularly for sprinkler and drip irrigated systems 近20年中,美国的灌溉施肥,尤其是通过喷灌和滴灌系统的灌溉施肥,增加极其迅速。 |
| 8. | In a short , answer to the optimizing length of porous pipe is very important in optimum design of trickle system 毛管和支管的直径以及设计压力水头一定的情况下,大于或小于毛管的经济长度,都会使滴灌系统的费用增加。 |
| 9. | It is especially critical for drip systems that must be kept free of suspended solids and microorganisms that plug small orifices in emitters 对于滴灌系统,水质更加重要,水中必须不含悬浮的固体颗粒和微生物,以防止阻塞滴头出水孔。 |
| 10. | This article is focused on the effect of field measures on the price and quality of drip irrigation system and exactly determining the quantity of irrigation water 本文着重研究的滴灌系统的田间工程对滴灌系统的造价和灌水均匀度的影响,以及精确测定灌水量的简便途径。 |
