Spatial Variations Of Moso Bamboo Plantation For Shoot Production In Soil Nutrition And Corresponding Recommendations To Regional Fertilize Application

Phyllostachys pubescens is one kind of bamboos, which with the widest distribution, largest covering area, and highest utility values, gather with the economic, ecologic, and social benefits on its growing area and the income of the farmers. As the rising of intensification management, the technology of bamboo forest fertilizing becomes more and more important. Balanced fertilizing plays an significant role in increase the bamboo productivity and efficiency as its sustainable development. This paper employs the method of participating and studying, probes the need of bamboo fertilizing technology, and establishes a regionalized fertilizing method through soil testing and field experiments. Main conclusions are as follows:1. By studying, it is discovered that there is a high demand of technology in improving the productivity and efficiency of bamboo forest in our country, and the fertilizing management is experience-decided. There is a lack of variety of fertilizers and the amount used is also not proper.2. By testing the soil, it is discovered that there is obvious spatial variability in soil nutrition. In deeper studying the management of fertilizing, it indicates that such variability is a result of the different fertilizing management. If there are bigger differences of the fertilizing technology between people, the variability will become more obvious in different fields and spaces. While if the fertilizing technology is similar, the difference will decrease after a long time.3. Regionalized fertilizing in Phyllostachys pubescens forest could accord to"two level"method, that is to use"one level"management in large areas where there are differences in soil, and to use"two level"management in areas where soil is the same and according to the different fertilizing technology. Then, give the suggestions after the soil experiments.4. As a result of the experiment in Suichang, it is shown that regionalized fertilizing, which compared with traditional method, is much easier in operation, and can objectively reflect the distribution of nutrition in the soil since it take nutrition into consideration. Therefore, it is very helpful in improving the productivity of bamboo forest and balance nutrition distribution in the soil.
