2, interpretation of result
2.1 Herba Cyperi Glomerati stems, leaf changing features
Test shows, under the different water depth gradient of 0-80cm, the rising that the long and Ye Kuanjun of the plant height of Herba Cyperi Glomerati, base stem, leaf shows as along with water level first increases rear downward trend (Fig. 1), wherein along with the further increase of the depth of water, plant height recruitment obviously reduces, the plant height recruitment of 0-20 cm is 14.97cm, 20-40cm plant height recruitment is 13.02cm; 40-60cm plant height recruitment is 5.92cm; 60-80cm plant height recruitment is-20.9cm.Base stem increasing degree under the different water depth gradient of 0-20cm is maximum, and under the depth of water of 20-60 cm, increasing degree is less, and under the 80cm depth of water, base stem have dropped 0.08cm than the 60cm depth of water.Leaf length increases 17.15cm at 0-20cm, only increases 2.29cm between 20-40cm, decreases 7.3cm between 40-60cm, and 60-80cm increases 1.49.Leaf is wide is increase trend between 0-60cm, but 0-20 increasing degree is comparatively large, and 80cm have dropped 0.06 than 60cm.One-way analysis of variance (One-way ANOVA) result shows, under each depth of water gradient, Herba Cyperi Glomerati plant height, base stem, leaf difference that is long, wide of leaf do not reach significance level (p > 0.05).Visible, along with the rising of water level, in the scope that it can tolerate, Herba Cyperi Glomerati is that the biomass by increasing the ground such as plant height, leaf length, Ye Kuan increases and the contact surface in the external world, to obtain the necessary energy of growth, this is the self-adaptation of plant to environmental change instinct, but this tolerance is within the specific limits, when the depth of water is more than 60cm, there is downward trend in this regulating power, plant height, leaf length, Ye Kuan etc. no longer increase, and illustrate that the depth of water now has exceeded the tolerance range of plant.
2.2 chlorophyll content changes
Under different water depth gradient, as shown in Figure 2, within the scope of 0-60cm hydraulic gradiant, along with the rising of water level, chlorophyll content is totally in increase trend for the difference between Herba Cyperi Glomerati chlorophyll content in leaf blades.One-way analysis of variance show this species diversity do not reach significance level (
p>0.05), be the highest during 40cm water level, reach (1.912 ± 0.146) mg.g
-1, and be minimum during 80cm water level, for the content of 64.4%. chlorophyll a during 40cm water level is totally higher than chlorophyll b (exceeding about 278.7%), and both and chlorophyll content have identical variation tendency, and minimum is respectively 63.3% and 64.4% of peak.2 results and analysis figure figure
2.3 underground biomass changes
As can be seen from the change (Fig. 3) of different water level biomass, 0-60cm hydraulic gradiant test time, the underground biomass of Herba Cyperi Glomerati all increases along with the rising of water level, and the difference between different water level reach significance level (
p<0.05), during its middle water level 20cm, stem tuber mean fresh in underground is 12.31g, is the maximum of all test depth of water, exceeds 27.04% than 0 water level, exceed 82.11% than the 80cm depth of water, but the underground stem tuber weight differential of 40cm and the 60cm depth of water is less.As can be seen from plant height, leaf is long, leaf is wide analysis, along with the rising of water level, ground biomass then has larger difference, visible, Herba Cyperi Glomerati is by regulating the allocation proportion of ground biomass and underground biomass to adapt to the water level constantly raised, when water level is more than 20cm, in order to increase the contact area with air, improve the acquisition speed of oxygen, reduce the consumption of breathing by reducing underground biomass, this is that plant is to the self-control of adverse circumstance and adaptation.Water level can be worked as when being increased to 80cm, underground biomass presents and significantly declines, be only 54.31% during 20cm water level, and there is putrefactive phenomenon in most stem tuber, visible, depth of water 60cm is a threshold value of Herba Cyperi Glomerati growing environment, more than 60cm, its plant height, leaf are long, leaf is wide no longer in the trend increased, but have the decline of a large scale.Herba Cyperi Glomerati is applicable to shallow water area growth in a word, is advisable, does not the highlyest exceed 60cm with the 20-40cm depth of water.
3 conclusions and discussion
1) in the depth of water graded of 0-60cm, Herba Cyperi Glomerati plant height, leaf length, Ye Kuan, base stem and subterranean stem fresh weight increase all to some extent, and as water level 20cm, this increase is the most remarkable, and during more than 40cm, increasing degree slowly reduces.When the depth of water is more than 60cm, Herba Cyperi Glomerati growth is subject to serious impact, and every analysis indexes all shows reduction in various degree, is exactly the most significantly wherein that underground stem tuber rots and weight reduction.Visible, Herba Cyperi Glomerati loses the ability of self-adaptation under high water level environment, and it is more suitable for the depth of water environment of below 60cm.
2) in the depth of water graded of 0-60cm, chlorophyll content is totally in increase trend, embody it, within the scope of the water depth ratio of 0-60cm, there is certain tolerance, when the depth of water is more than 60cm, chlorophyll content presents downward trend, and it grows the impact received to a certain degree, finally causes yellow leaf, plant is short and small, and underground tuber biomass reduces and rots.
3) found by above result of the test, Herba Cyperi Glomerati is suitable at shallow water area growth and breeding, and 20-40cm is its optimum growth water level, and Herba Cyperi Glomerati population quantity within the scope of this depth of water is comparatively large, grows more prosperous.But when water level rises again, it also has certain tolerance, the threshold value of this tolerance is 60cm.
4) should select at upstream bank band the zone design plantation pool that water-level fluctuation is less, be suitable for Herba Cyperi Glomerati growth for Herba Cyperi Glomerati child care, Artificial Control water level (20cm≤H≤40cm), to reach the object of child care.
Owing to have employed technique scheme, compared with prior art, the present invention sets up the little pond of water-level fluctuation, in pond, plant Herba Cyperi Glomerati, control the water level in pond, make Herba Cyperi Glomerati obtain its optimal depth condition that grows, thus maintain its normal growth, obtain maximum underground tuber biomass, realize the artificial child care of Herba Cyperi Glomerati, for the extra large Wintering area of grass provides more food.The present invention is simple, with low cost, and result of use is good.
