Show model combines growth model, math model and VR technologies to design the proper object structure of each organ of virtual plant. First of all,research background, research content of virtual plant area and Virtual Reality technology are introduced. The concept of VR and research content of virtual plant are defined. Secondly, we analyze math model of virtual plant, including Bezier curve, NURBS curved surface, fractal system, L-system and Catenary curve. Thirdly, we give show model of virtual plant in detail. Finally, the design of the platform and growth model on XML script is introduced , and how to show the virtual plant in the platfrom is discussed too.

It seeds area and total yield are big in our country.This study combined Hubei province item of the project of country important food foisori science and technology. It considered the difference of climate character、 cultivate system and plant habit in the southeast of Hubei、 in the middle of Hubei、 in the northwest of Hubei and in the Jianghan plain four rice plant areas. It had formed " double season rice three ripe high yield in the southeast of Hubei mode "、" sparse、 manipulative、 weight middle season rice high yield in the middle of Hubei mode"、" zero till light-duty high yield plant in the Jinghan plain mode" and " cover with ground film wet in all process in the northwest of Hubei plant mode" four adaptive plant modes base on present plant modes.

降低经营费用连锁经营企业以顾客自我选购、自我服务的经营方式为主，减少厂售货劳动，因而雇员相对较少，节省厂}一资成本，节约厂场地费用在连锁超市中，商品明码标价，顾客可以自由挑选，顾客节省厂购物时间，也节省厂企业的经营成本同时，加快厂顾客的流通速度，增加厂客流量总之，连锁经营与非连锁经营在总成本费用上的差距很明显我们对同样数量的两种企业进行抽样调查显示，连锁经营企业的费用较之其他零售商场约低10个白一分点

A field trial for plant density has been used for practical remediation in 2004 and 2005, it has four treatments, 10 cm×10 cm、20 cm×20 cm、10 cm×40 cm and 40 cm×40 cm, respectively. The results were follows: the optimization plant density was 20 cm×20 cm; Peteris vittata L. was a herbaceous plant fit to adequacy increased density for enhancing the biomass and removalling of arsenic; with increased the plant density, the plant were accumulated more proportion arsenic in their fronds, and then made promote the efficiency of arsenic removal from contaminated soils.(2) It was a complicated pyrolysis course for plant incineration.

1在10cm×10cm、20cm×20cm、10cm×40cm与40cm×40cm 4个种植密度下，利用蜈蚣草对砷污染土壤进行了2年的田间实际修复，得出如下结论：蜈蚣草是一种适宜于密植的草本植物，具有通过提高栽培密度来提高其地上部生物产量的潜力；同时蜈蚣草密植有利于促使其吸收的砷向地上部富集，从而有利于进一步提高其对砷污染土壤的修复能力；综合考虑修复过程中的收获方式、经济成本与可操作性，在4个密度处理中密度20cm×20cm为蜈蚣草的最佳栽培密度。
