节水栽植摘要翻译校正

本人道路工程，偶然机缘撰写了这方面文章，并申请了专利。 本文通过室内实验与现场试验研究了塑胶瓶的节水栽培性能。室内模拟不同的水分散失条件，连续多日定时测试塑胶瓶内砂土的含水量，回归分析剩余含水量随时间的变化函数。结果表明：温度越高，水分散失速度越大；由饱和含水量至萎蔫含水量，在室温下可以间隔9天浇水一次；漏斗状比直筒状有利于延迟水分渗透；砂粒与有机肥比粘粒有利于锁住水分，可用以调节水分散失速度。现场栽植试验（有瓶与无瓶）比较亦证实该方法的有效性。由于漏斗状塑胶瓶具有留存水流与延迟渗透的节水功效，有利于缺水或高渗透地区草灌植物的栽培。 .The water saving cultivation performance of funnel-shaped plastic bottle was studied in this research though laboratory and field tests. Different conditions of water loss were simulated in the laboratory, and regular tests of the water content for sandy soil in the plastic bottle were conducted for continuous several days. Then, functions of the remaining water content of sandy soil with time were achieved by regressive analysis method. Results showed that the higher the environment temperature, the greater the rate of water loss. From the saturated water content to the wilting water content, an extended interval of watering could be as long as 9 days at room temperature. The funnel-shaped bottles could delay water loss more than the straight cylinder-shaped bottles. Both sand particles and organic fertilizers were more facilitated to lock water than clay soil particles, and they could be used to adjust the rate of water loss. Comparisons of field planting tests (with bottles and without bottles) confirmed the effectiveness of this method. Due to better efficacy of water saving and accumulation，funnel-shaped bottles can be used as subsurface drip irrigation, and will benefit plant culturing in water-starved or hyper-osmotic area. |
