Covering the surface can increase ground temperature, reduce evapotranspiration, inhibit weeds, and reduce pests. It has been widely used in many crops, especially in vegetable cultivation. In 1948, Japan took the lead in using groundnut to cover cultivation. Taiwan introduced this technology in 1983. The comprehensive cultivation results of various researchers showed that the number of pods per plant and 100-grain weight per plant increased when the plants covered with traditional plastic sheets were better than those without mulching, indicating that the plastic covering with peanuts had the effect of increasing production. Due to the use of traditional plastic film for covering the surface of the mulch; after the crop is harvested, it takes time to pick up the plastic film. It has been reported that in the case of groundnuts, if the remaining film in the soil does not pick up, in the first year and the second year will result in 11.1 - 16.1% reduction in groundnut production. In addition, plastic film recycling is time-consuming and adds extra manpower. According to the Taiwan Bay Annual Report 2001, Taiwan's annual cultivation of groundnuts under cultivation was 25,183 hectares. Under the pressure of the shortage of rural labor force after the introduction of WTO, the trials were conducted to evaluate the effects of degradable plastic film on the surface coverage of peanuts. In addition to achieving the purpose of labor cultivation, it is also possible to increase the harvest. Improve quality and adjust the date of production as a reference for future promotion. In August 2001, Taiwan began to evaluate the biodegradable membranes on the ground cover planting of peanuts. The four bio-degradable membranes, Tianjin Dan, degra-novn, mater-bi, and Dori, were used for the evaluation of the fall cultivation of groundnuts in autumn. The preliminary results show that: each test film can improve the germination and outburst rate of the peanut seed, and the sprouting explanted rate of the open field cultivation on the 7th day after sowing increased by an average of 51.4%, resulting in rapid plant growth and early flowering. For each test film, the flowering rate on the 24th day after sowing was increased by 16.8 and 19.3%, respectively, compared with the conventional pe film and open field cultivation. On the 27th day after sowing, the cultivation in open field was slower and the flowering was slower. The flowering rate was only 44.4. %. After plant flowering and pollination, elongation of the ovary stalk was different for the penetration of the test membrane, and most of them were between 13 and 16%. Only mater-bi biodegradable membrane was up to 30.8%. It is worth further exploring the reason. The other peanut covered the Decomposition Membrane, which is only 21% due to the low open-ratio, and the total number of pods in the plot is large, and the fresh pods and kernels are heavier, so the yield per unit area is also better. Based on preliminary observations made in this experiment, it was found that it is feasible to use biodegradable membranes to cover groundnuts. Only the thickness of the decomposed membranes, the most suitable materials for sowing or transplanting and covering, and the cultivation modes and economic benefits are still needed.
