摘要

在 2022 年的旱季进行了一项田间研究,旨在调查不同水稻种植方法对水稻能量和水分预算的影响。实验采用随机区组设计,三次重复。研究了七种处理,包括三种插秧方法,即自力更生育秧法、机械插秧法和传统插秧法,以及四种直播水稻(DSR)方法,即湿直播水稻(滚筒播种)、湿直播水稻(播种)、干改湿水稻(播种)和干改湿水稻(行播)。结果表明,化肥、灌溉水、整地、播种或插秧作业占所有水稻种植方法投入能源的 80%左右。在水稻种植方法中,传统插秧的输入能耗最高,为 21723.9 兆焦耳/公顷,而干湿转换水稻(行播)的输入能耗较低,为 18394.3 兆焦耳/公顷。在输出能方面,湿法 DSR(滚筒播种)的输出能最高,为 141781.1 兆焦耳/公顷,而干转换湿法水稻(直播)的输出能最低,为 77223.2 兆焦耳/公顷。湿法 DSR(滚筒播种)的输出能量与 SRI 和干法转化湿稻(条播)相当。同样,旱改湿水稻(行播)的灌溉水生产率(0.73 千克/立方米)和总水生产率(0.30 千克/立方米)较高,需水量减少了 630 毫米。与传统插秧相比,干湿转换水稻(行播)的投入能耗和灌溉水需求分别降低了 18.1%和 51.9%,干湿转换水稻(直播)分别降低了 17.4%和 51.9%,SRI 分别降低了 16.9%和 36.7%,湿法 DSR(滚筒播种)分别降低了 9.13%和 27.6%。因此,建议在特兰甘纳邦采用湿法 DSR(滚筒播种)、SRI 和干转湿水稻(行播)进行节能节水水稻生产。

Energy and water budget of rice under different establishment methods
A field study aimed to investigate the influence of different rice establishment methods on energy and water budget of rice was conducted during kharif season of 2022. The experiment was carried out using a randomized block design with three replications. Seven treatments were examined, including three transplanting methods viz., SRI, mechanical transplanting and conventional transplanting, and four direct seeded rice (DSR) methods viz., wet DSR (drum seeding), wet DSR (broadcasting), dry converted wet rice (broadcasting) and dry converted wet rice (line sowing). Results revealed that chemical fertilizers, irrigation water, land preparation and seeding or transplanting operations constituted ~80% of the input energy in all rice establishment methods. Among the rice establishment methods, conventional transplanting exhibited the highest input energy of 21723.9 MJ ha-1, while dry converted wet rice (line sowing) recorded the lower input energy of 18394.3 MJ ha-1. In terms of output energy, wet DSR (drum seeding) recorded the highest value of 141781.1 MJ ha-1, whereas dry converted wet rice (broadcasting) registered the lowest value of 77223.2 MJ ha-1. The output energy of wet DSR (drum seeding) was comparable to that of SRI and dry converted wet rice (line sowing). Similarly, dry converted wet rice (line sowing) exhibited higher irrigation water productivity (0.73 kg m-3) and total water productivity (0.30 kg m-3) with a reduced water requirement of 630 mm. Compared to conventional transplanting, input energy consumption and irrigation water requirement was lower by 18.1% and 51.9% in dry converted wet rice (line sowing), 17.4% and 51.9% in dry converted wet rice (broadcasting), 16.9%, 36.7% in SRI and 9.13%, 27.6% in wet DSR (drum seeding) respectively. Thus, the adoption of wet DSR (drum seeding), SRI and dry converted wet rice (line sowing) is recommended for energy and water efficient rice production in Telangana.
