摘要
为研究无人机精量播种对水稻产量影响,探究该项技术在上杭县水稻应用的可行性,结合上杭县地理气候条件与栽培习惯,选用水稻品种韶优766,设置2种无人机精量直播用种量和常规人工插秧(CK)处理。结果显示:水稻品种韶优766在相同用种量(0.75 kg)情况下,无人机精量直播每667m^(2)产量达529.2 kg,比常规人工插秧减产0.95%,但差异不显著;在不同用种量情况下,以无人机精量直播每667m^(2)用种量0.60 kg处理的产量最高,达570.9 kg;同时研究发现2个无人机精量直播处理在水稻成熟期均出现倒伏,说明直播稻比较不抗倒伏。综合对比3种处理,韶优766在上杭县采用无人机精量播种每667m^(2)适宜用种量为0.6 kg,每667m^(2)可实现节本增效211.1元,达到作业高效、节本增效目标,但还需从品种、田间管理、抗倒伏等方面进一步完善该技术模式。
In order to study the impact of UAV precision seeding on rice yield and explore the feasibility of the application of this technology in Shanghang County,combined with the geographical and climatic conditions and cultivation habits of Shanghang County,rice variety Shaoyou 766 was selected,and two kinds of UAV precision direct seeding and conventional artificial transplanting(CK)were set.The results showed that under the same seed consumption(0.75 kg)of rice variety Shaoyou 766,the yield of UAV precision direct seeding per 667m^(2) was 529.2 kg,which was 0.95%lower than that of conventional artificial transplanting,but the difference was not significant.In the case of different seed consumption,the yield of 0.60 kg per 667m^(2) of UAV precision direct seeding is the highest,reaching 570.9 kg.At the same time,the study found that the two UAV precision direct seeding treatments lodging in the mature stage of rice,indicating that direct seeding rice is less resistant to lodging.By comprehensively comparing the three treatments,and the appropriate seed amount of Shaoyou 766 was 0.6 kg per 667m^(2) adopting UAV precision seeding in Shanghang County.The cost saving and efficiency increasing of 211.1 yuan per 667m^(2) can be achieved,so as to achieve the goal of high efficiency and cost saving and efficiency increasing.However,the technical mode needs to be further improved from the aspects of variety,field management,lodging resistance,etc.
