吉林省梨树县不同作物产能及产能水分利用效率研究
|
摘要
东北地区旱地作物水分来源是降水,基于产能及产能水分利用效率比较分析吉林梨树可替代玉米种植的主要作物对该地区未来种植结构调整具有重要意义。该文基于吉林省梨树县4种作物(大豆、小麦、谷子和马铃薯)2 a田间试验,结合各作物在不同降水年型条件下全生长季和各生育阶段的耗水规律及水分亏缺程度,以作物产能和产能水分利用效率为研究指标,对各作物在雨养及灌溉处理条件下的产能水分利用效率和水分经济效益差异性进行了比较。结果表明,在平水及丰水年,马铃薯产能显著高于其他作物,其他作物无显著差异,雨养条件下马铃薯及谷子均超过100 000 GJ/hm~2,不同降水年型条件下灌溉对马铃薯产能提升效果显著但提升幅度存在差异。比较各作物不同年型条件下的产能降水利用效率、产能灌溉水利用效率和产能农业水分利用效率,马铃薯均达到20 GJ/mm以上,显著高于其他作物,且不同作物的产能水分利用效率受降水年型及水分处理影响的程度不同。对比作物需水量与降水量的耦合程度,马铃薯水分亏缺最严重,其次为大豆和小麦;谷子产能降水利用效率及丰水年产能农业水利用效率仅低于马铃薯,且在全生育期各生育阶段发生水分亏缺现象较少,具有极好的抗旱能力。比较而言,基于作物产能、产能水分利用效率及经济效益的作物结构调整,马铃薯和谷子相对于小麦和大豆有更大优势;基于作物抗旱能力,谷子具有绝对优势。
Northeast China is an important grain production area of China. The maize planting is increasing recently. In this study, we explored the production capacity of the other crops in order to provide valuable information for laying out more reasonable and effective planting structure in the Northeast China. 2-year experiments were conducted in Lishu county of Jilin Province in 2016 and 2017. Crop treatments by water treatments were designed. Crops included soybean, wheat, millet and potato and 2 water treatments included irrigation and rain-fed method. The crops were planted in traditional way. The crop yield and soil water content were measured. The water consumption was calculated based on water balance equation. The water deficit rate was defined as the percentage of difference of precipitation and water requirement and water consumption. Water requirement was calculated based on potential evapotranspiration of FAO formula and crop coefficient. The water use efficiency was calculated based precipitation, irrigation and their sum. Then the yield and water use efficiency were converted into energy in order to compare different crops. Economic benefit of these 4 crops under different water treatments were compared. The results showed that compared to historical average, the year of 2016 was wet year and the year of 2017 was normal year. In the wet year, the precipitation was rich during the early and middle stages of crops while it was scarce during the early and late stages of the crops. The crop water requirements were higher than or equaled to in the wet year than in normal year. The wheat-buckwheat had the highest crop water consumption in 2016 while the potato had the lowest water consumption. During the initial stage, most of the crops had surplus precipitation. By the middle stage, most of them started to show shortage of precipitation. For the whole growth period, the water deficit of potato was the highest and that of the millet was the lowest. The potato had higher production capacity(over 100 000 GJ/hm~2 under rain-fed treatment) than the other crops. The production capacity of the other crops was not significantly different(P>0.05). Irrigation could only improve production capacity of potato. However, the impact of irrigation on potato production capacity was different in different precipitation patterns. In normal year, the increase of production capacity of potato was much higher than the wet year. In addition, the water use efficiency of production capacity of potato was higher than the others. The irrigation water use efficiency of potato could be more than 20 GJ/mm, far higher than the other crops. Thus, the economic benefit of water use based on production capacity of potato was also the highest. Compared to the soybean and wheat-buckwheat, the millet was higher in the economic benefit of water use based on production capacity in wet year. Therefore, potato and millet had greater advantages than soybean and spring wheat in planting structure adjustment based on crop production capacity, the precipitation use efficiency in production capacity, irrigation water use efficiency in production capacity, agricultural water use efficiency in production capacity and economic coefficient in Lishu county of Jilin province.
