The climate in our country is East Asia Monsoon Climate with unstable climate system. The characteristics of this climate are seasonal rainfall and large regional variation. Since the reform and opening up, China economy is developing very fast, and the level of people’s life is increasing as well. With these, offering long-term population growth and environmental degradation have intensified the contradiction between human and nature, even makes our country suffers more and more frequent flooding, especially in east and central regions of our country. In marshland, wet land and lake area, disaster always come after flood and rainstorm which will harm for agriculture and forestry industry. Flood disaster always obstructs growth of plants and its concrete manifestation is oxygen deficit of root system by water flooded and excessive soil moisture. At present solvable measure includes research of water logging resistance genes, involving agricultural cultivation measures planning, for trees and cloning of genes conferring, water conservancy, timely drainage method and so on.Also it seems to have no effective solution can solve plant oxygen deficit which cause the water flooded and other nature conditions. With the development of science and technology, a new fertilizer that can solve the problem of plant oxygen deficit has been invented. It can control and release oxygen slowly. But this fertilizer is a new developing fertilizer and technology, so that there are many difficulties for us to conquer.This article is used for solve the problem of plants oxygen deficit. Basing on fertilizer which is necessary for growth of plant, to research production and preparation, application technology of new fertilizer which can control and release oxygen slowly.To get the new fertilizer which can control and release oxygen slowly must produce as following steps. At first, the production and preparation of new type oxygen fertilizer used red clay as a filler. Red clay is common in the south of China. Then, using calcium peroxide powder as the core material, superphosphate as buffer agent, adding the adhesive and hybrid tablet. At last, using the paraffin to parcel the suppress tablet.The result which through experiment in the researching of production and preparation of new type oxygen fertilizer shows that pH of new type oxygen fertilizer cam always stay in neutral range by hydroponic. Also, when release the oxygen, fertilizer still stay in a low and stable status. It means it will not pollute the soil environment for plant growth. For example, common fertilizer will cause soil microorganisms and microcosmic decreasing, microbial species changing and other microcosmic changing. In addition, the new type oxygen fertilizer sustained release about30days, and can be used in releasing oxygen slowly, providing oxygen for plants, and relieving flood disaster to plants. Experiment shows that this new type oxygen fertilizer has some characteristics which include environmental friendly, abilities of controlling and releasing oxygen slowly.Experiment with the method of artificial simulation flooding stress. In the different period of flooding stress, physiological and biochemical indicators of Taxodium ascendens have been changed and weakened obviously. By contrast, activity of antioxidant enzyme system SOD, POD have changed and returned to normal level by different ways of fertilizer applying new type oxygen fertilizer. It proves that the new type oxygen fertilizer can provide oxygen for plants, can alleviate energy demand in plants, reduce the process of anaerobic respiration metabolism, transform of oxygen plants to aerobic respiration, and maintain the normal growth of plants.Under the flooding stress, the key of new oxygen fertilizer application technology are fertilization methods and appropriate fertilizer. It means in this article selects soil surface and the soil beneath the surface5cm, annual size Taxodium ascendens and applying oxygen fertilizer35g,45g,55g, which invented by this article. Using weighing method to control soil moisture content, observation Taxodium ascendens growth status every day and testing SOD, POD activity of antioxidant enzyme system. It can get conclusion of the technical specification of new oxygen fertilizer when fertilizer is used, in order to maintain Taxodium ascendens growth.
