The Study On The Effects Of Reciprocal Resource Patch Scales And Orders On The Clonal Growth Of The Zoysia Japonica

One of the main advantages of clonal growth in plants is physiological integration through the physical connection of "individual", which could share water, nutrients and photosynthetic product.And this could scatter the risk of single ramet, increasing survival rate of offspring ramets. It is generally believed that there is a certain complementarity or substitution effect among different resource types in economic system, which may produce different benefits under different scale or combination conditions. Human naturally formed effective phenomenon of division of labor through the effective use of these factors in the economic system, and the division of labor has become more and more meticulous and specialization along with the development of social economy. The environment of plant survival is generally heterogeneous. The clonal plants in this kind of environment also cause the phenomenon of labor division, and thus form a unique ecological strategy. The study on this strategy has become one of the hot issues in the research of clonal plant ecology. Although there have been many previous studies carried out, the key details of the issue is still far from being revealed. Based on this, we takes the typical stoloniferous clonal plant as the research object, carry out the interactive resource patch scale to study the impact of clonal growthThe key point of this paper is how to influence the clonal growth of the clones in the different resource levels and different patches scales and orders? When two kind of resources are interactive distributed, what are the effects of the the clonal growth in different resource levels and different the patch sizes and the orders of the repeated changes clones. These problems are often encountered in clonal plants under natural habitat conditions, but the previous research has never been involved, and the relevant theoretical research is difficult to get a clear prediction results. Obviously, this study is to deepen and refine the research on the labor division of clonal plants.In order to explore scientific problems proposed in this paper,experiment I was designed for the same resources in different levels and patches of different scales and orders which repeat the continuous variation, Experiment II was designed for two kinds of resources distribution, and patch sizes and orders were repeated continuously varying,Experimental results show that:1when single resource (water, nutrients, irradiance) repeated continuously changes in different levels and in different patch scale, total biomass of Zoysia japonica clonal plant was significantly increased in some treatment (such as B2+), and in the other experimental treatment(such as A1), total biomass did not change obviously. Total biomass has significant effects in different orders of one kind of resource of different levels of Zoysia japonica clones (such as the A3 treatment).2 There is no significant difference in the total biomass in one ramet patch scale, and the effect of the orders of resource patches on the total biomass of the plant was not significant too.3 In the heterogeneous habitat conditions of two kinds of resources distributed interactive and repeat the continuous variation,total biomass have no significant difference in experimental group of different resource patch scale of Zoysia japonica clones, but under the three ramets patches scale conditions, water and light, water and soil based on the N/P in resources distributed interactive and repeated changes in heterogeneous habitats of Zoysia japonica clons, total biomass has significant influence. Under the conditions of this kind of heterogeneity patches, the integration and the effect of labor division are obvious.4 Surprisingly, compared with that of water deficiency, the biomass of individual plant of Zoysia japonica slightly increased under the condition of water sufficiency, when grew in heterogeneity habitat with repeated continuous change of water and light, water and patchily distributed resources based on N:P ratio.5 Under the heterogeneous patches condition,1 ramet patch and 12 ramets patches is not significant, although 3 ramets patches have significant influence.
