Study On Manufacturing Technology And Application Of Biodegradable Pot

There are plenty of all kinds of crop straws in our country (about 0.7 billion per year output). With the development of the economy and the society, the crop straws in the main area of grain-producted were overstocked day after day. Furthermore, the farmers usually discarded the straws at will or set them on fire without control, and it brought serious waste resources and polluted environment. Therefore, it was an important item to exploit new environmental product and to find new technology in the stratagem of our country continuable development.A small experiment in the lab was conducted with rice straw to study the pretreated technics affecting the straw mold pressed pot, the dosage and category of opsonin. And the complexed substrates suitable with the pot were choosed, and the pot was also put in the small experiment and an application experiment. What's more, the technics of the small experiment were taken to a middle-magnified experiment. The main results were presented as follows:The straw pretreated technics of basification and stack decompose were both reduce the intension of the straw pull resist effectively and elevated the fluidity and plasticity of the material. There were many factors which affected the intension of the straw pull resist and its plasticity, such as the kind, dosage and its treated time of the alkali, the C:N:P of the compost material, whether using inoculable matter or not and the compost time. Within the scale of 16%NaOH and 20%CaO, using alkali to treat the crop straw, the effect of the treat -ment boosted up with the increasing alkali.In the way of stack decompose, using inocul -able matter and appending N and P fertilizer helped to decompose the crop straw. Similar results were obtained, that the in a piece of rice straw dropped to 100-116N, the treatment had been finished.Due to the high salinity of the pot, which were made with the treatment of alkali, the seedlings were restrained seriously in anaphase. The straw pot made by the means of stack decompose can accelerate the growth of the plant comparing with the control. The pot may decompose within a short time, and can be passed by the crop root in about 20 days. The straw pretreated technics of basification was not a feasible method and the technics of stack decompose is a better straw pretreated method. All kinds of pot with different filled matters showed better glabrous appearance. In the application experiment, the pot filled with 20%...
