| 1 | Effects of continuous and pulse irrigation with different nitrogen applications on soil moisture,nitrogen transport and accumulation in root systems显示文摘Pulse and continuous irrigation can affect water distribution in the soil,thereby affecting the growth and distribution of root systems.Different base and topdressing fertilizers can affect nitrogen transport in the soil and root distribution,thus affecting root water and nitrogen uptake.This study used pot experiments to set up four different nitrogen levels,including two different irrigation methods,to research the effects of soil moisture,nitrogen transport,nitrogen accumulation and root systems under the conditions of continuous and pulse irrigation,as well as different nitrogen applications.Result showed that continuous irrigation can increase the moisture content around the drip emitter position and reduce the soil moisture content in the horizontal spreading compared with pulse irrigation,especially reducing the horizontal spreading in the deep soil layers.One treatment in this study did not apply base fertilizer,and then supply topdressing fertilizer at a ratio of 2:4:4 in the seedling stage,jointing stage and tasseling stage,respectively.This treatment is beneficial for improving nitrogen utilization efficiency.Furthermore,this treatment can increase the root length density and root surface area in the deep soil layers,especially in the 20-35 cm soil depth,and to some extent increase the deep growth of the root system. | Lingmiao Huang Peiling Yang Shumei Ren Haobo Cui | 2018 | International Journal of Agricultural and Biological Engineering2018，11，5： | 2 |

| 13 | Effects of topdressing ratio and frequency on the dry matter, yield, and quality of tomato and celery under a small amount of continuous subsurface drip irrigation显示文摘Compared with conventional full irrigation,the existing water-saving irrigation method achieves the purpose of water saving by actively controlling soil moisture.High-frequency irrigation can make the ideal conditions for soil water movement and root absorption of water and nutrients.This research used a plot experiment in a greenhouse and set up different fertilization amounts and frequencies during the growth stage to study the effects of small-amount and continuous subsurface drip irrigation on the dry matter,yield,and quality of tomato and celery.The results showed that the frequency of topdressing had a great influence on the dry matter accumulation of tomatoes,and the amount of topdressing had little effect on the fresh weight of the upper part of a tomato plant.The application of high-frequency fertilizer increased the dry matter accumulation in the underground part of the tomato.Under the premise given amount of total fertilization,the growth rate and yield of tomatoes were positively correlated with the amount of topdressing.The optimum fertilization frequency was 1 time during the first fruit stage,3 times for the second fruit stage,and 5 times for the third fruit stage,the yield during the fourth stage was increased with higher frequency,and the topdressing was started ahead of the fourth fruit stage when the diameter of fruit was 40 mm.The lower fertilization frequency during the early stage and higher fertilization frequency during the later stage can increase the yield of celery.The higher ratio of topdressing,the higher frequency during the early growth stage,and the lower frequency during the later stage can achieve the best quality of celery. | Lingmiao Huang Peiling Yang Haobo Cui Zhanghao Sun Shumei Ren Zhaocheng Wang | 2023 | International Journal of Agricultural and Biological Engineering2023，16，3： | 0 |
