辽宁是我国北方严重缺水的省份之一,在长期与干旱的斗争中,发展了节水型稻作,插秧稻的浅湿间歇灌溉,直播稻的旱种、旱作,地膜覆盖种稻,以及用水上躲开辽河枯水期,充分利用降雨的大秧迟栽技术和水稻与小麦、大麦、油菜、绿肥等的轮作复种技术,构成了辽宁节水型稻作的基本内容。这套具有特色的水稻节水高产栽培技术的推广应用,使辽宁省近年来水稻生产发展较快,种植面积已达700万亩,平均亩产1984年达510.5公斤。

Based on four year'sfield plot experimental results,this paper confirmed preliminarily that by dry cultivation (namely,the type of drysowing and dry-mangement,and with no water layer in all its lite),the hybrid of rice (O.sativa L.Subsp Keng Ting)could raise the efficiency of irrigated water (paddy yield/m~2).Upon this the basic theory basis has been discussed.

The field experiments conducted over the past three years indicate that the methane emission fluxes from the rice paddies vary drasticaly with various agricultural measures. During the three late rice growing seasons from 1990 to 1992, CH4 emission fluxes from the experimental fields were 10. 83, 25.18 and 19. 85 mg/m2. h, respectively. Semi-dry cultivation reduced the CHt emission fluxes by about one third, sunning field, applying ammonium sulfate and intermittently flooded irrigation might also make...

The field experiments conducted over the past three years indicate that the methane emission fluxes from the rice paddies vary drasticaly with various agricultural measures. During the three late rice growing seasons from 1990 to 1992, CH4 emission fluxes from the experimental fields were 10. 83, 25.18 and 19. 85 mg/m2. h, respectively. Semi-dry cultivation reduced the CHt emission fluxes by about one third, sunning field, applying ammonium sulfate and intermittently flooded irrigation might also make the CH4 emission fluxes decreased significantly. The principal reasons for high CH4 emission fluxes are heavy application of organic fertilizer and long-term flooding. The key of controlling CH4 emission lies in regulating irrigation water. As long as a proper irrigation scheme is adopted, an increase of organic fertilizer may not be followed by an increase of CH4 emissions.

经过三年的田间试验发现,稻田甲烷排放通量随着农业措施的不同而大幅度地变化。在1990年至1992年的三个晚稻生长季节里,试验地块的甲烷排放通量分别为10.83、25.18及19.85mg/m~2·h。半旱式栽培使甲烷排放量减少了约1/3;施用硫酸铵、烤田、间歇灌溉亦可显著地降低甲烷排放通量。高有机肥与长期淹水是造成稻田甲烷排放量大的主要原因。控制稻田甲烷排放的关键在于调节灌溉水。只要采用合适的灌溉制度。有机肥用量的增加不一定引起甲烷排放量的增大。
