In this paper, a method of the numerical simulation for predicting soil water movement under subsurface irrigation with permeable tubes is presented.The physical process within the flow region is analyzed first, and then the numerical models are presented. Combining the Darcy's law and the law of conservation of matter, we obtained the governing equation which may be written in rectangular coordinates, as well as in polar coordinates. Each of the above equations contains two auxiliary functions, K(θ) and D(θ),...

In this paper, a method of the numerical simulation for predicting soil water movement under subsurface irrigation with permeable tubes is presented.The physical process within the flow region is analyzed first, and then the numerical models are presented. Combining the Darcy's law and the law of conservation of matter, we obtained the governing equation which may be written in rectangular coordinates, as well as in polar coordinates. Each of the above equations contains two auxiliary functions, K(θ) and D(θ), thus they are nonlinear partial differential equation. It is considered that the ring of quasi-saturated soil around the permeable tubes may increase as time goes on. So moving boundary condition is applied.In this paper, a numerical analysis based on a finite difference scheme involving the use of iterative alternating direction implicit and prediction-correction techniques is feasible to carry out numerical simulation model. With the aid of digital computer TQ-16, the results of numerical solution at each node are obtained.The laboratory tests to determine the characteristics of infiltration during subsurface irrigation were run in a large soil chamber with inside dimensions of 150× 150 × 20cm3. The experimental data are compared with the predictions of the numerical simulation.Based on these comparisons, it was concluded that the numerical simulation presented herein can be used to predict soil water movement under subsurface irrigation for some practical purposes.

本文首先对渗灌时土壤水流的物理过程进行了描述,并且确定了所研究的土壤水流区域:然后在此基础上,以边值问题的形式写出了两种数学模型.模型中采用Richards方程作为控制方程,它可以写成直角坐标或极坐标方程的形式.在透水管附近的土壤中,可能会出现含水量接近或达到最大饱和度的高含水带,其范围大小将随渗灌历时增长而逐渐扩大.考虑到这一情况,本文采用了可动的边界条件. 由于控制方程是非线性的,所以本文不是直接用解析法求解,而是采用以有限差分为基础的数值方法,并借助TQ-16型电子计算机实现这种计算. 为检验文中的数学模型是否可靠,作者在试验室内做了实体模型试验.试验土槽尺度为150×150×120厘米~3,内填砂壤土.通过对试验结果与数学模拟的分析比较,可以看出它们之间基本上是一致的,因此认为文中的数学模拟方法是可行的.

The mulberry beetle Abirusfortunei(Baly) , a major leaf insect pest of mulberry in spring leaf period, has one generation every two years in Xiushui County, Jiangxi Province. It overwinters with adult and a few middle size larvae in soil chamber 15-60 cm underground in mulberry fields. The adults come out of hibernation since late April to early June and feed on the tender leaves of branch tips, their serious damage occurs in the end of April to middle June. The initial capulation is taken place 5 days after the adults go out from the soil, and the peak times of copulation and ovipo-sition are in early-middle May and late May-middle/late June, respectively. The larvae hatch successively since middle May to middle August and feed on the underground part of mulberry tree, within the range of 10-65 cm, mainly in 30 - 50 cm, under the soil surface. All the larvae in the first year of development overwinter in the soil chamber individually since middle/late November and no pupation occurs in this year. They feed again since middle/late March next year, and pupate in early September to middle October, the adults emerge in late September to late November in soil chamber and get into hibernation without movement. Naturally, the durations of egg, larva, pupa and the lifespan of adult are 9-10 days, 15 - 16 months, 15 - 19 days and 8 - 9 months (including 6 - 7 months in dormancy underground), respectively. To control this insect pest, the ento-mopathogenic nematodes can be used on the soil surface to suppress the larval density underground, and use appropriate amount of selective insecticides in the peak occurrence time of adult combined with artificial catching.

桑皱鞘叶甲是桑树春叶期的重要害虫,在江西修水县2年发生1代,以成虫和中等大小的幼虫在桑园土下15~60cm深处的土室内越冬,越冬成虫于次年4月下旬至5月上旬大量出土并繁殖为害,为害高峰期为4月底到6月中旬。幼虫分布范围为土下10~65cm,其中以30~50cm最多。当年孵化的幼虫至11月中下旬开始越冬,次年3月中下旬继续取食和生长,9月上旬至10月中旬化蛹,9月下旬至11月底羽化并静伏于土室内过冬。在自然条件下各虫态发育历期为:卵期9~10d,幼虫期15~16个月,蛹期16~19d。成虫寿命8~9个月,其中土下蛰伏6~7个月,出土生活2~3个月。可用昆虫病原线虫压低土中幼虫密度及成虫高峰期施用杀虫剂,并辅以人工防治的方法防治该虫。
