영어 초록
Recent growing about global warming has led to increase the need for low-carbon, green growth policy at the agricultural sectors and interest in the environmental-friendly and organic products. Therefore, Korea government has decided to reduce the use of chemical fertilizer at the farm field up to 40% and in order to attain this goal, promoting to grow green manure crops has been taken into positive consideration in terms of maintaining soil fertility and preventing soil loss. To this result, the acreage to cultivate green manure crops has been sharply increased from 4,000ha in 1998 to 225,000ha in 2012. Regarding environment-friendly agriculture, bulk of rice straw should be incorporated into the paddy just after harvest as soil cover materials and also green manure crops, such as chinese milk vetch, rye, Hairy vetch and so on have been recommended to be grown annually as soil cover crops. General sowing process of a certain seed crop at the farm field consists of plowing, harrowing, seeding, covering up seeds with soil in order. This process at the field has been known to take relatively long time and even not to be equal at the seeding depth. For this reasons, new seeding technology has been continuously required by farmers. Partial-tillage seeder consisting of dressing furrow and seeding parts enable to overcome germination barriers. Two soybean cultivars, ‘Taekwang’ and ‘Shingi’ were used to test the performance of newly-developed seeder and its establishment rate showed around 70 ~ 90% with given interval of embedded soybeans. Furthermore, the partial tillage technology applicable to the soybean field could reduce labor cost by 69% as well as 22% of the fuel consumption and also promote soybean productivity per unit area.참고 자료
