| 【目的】针对蔬菜生产中水肥供应过量造成水肥利用率过低且污染环境这一普遍存在的问题，以菠菜为材料，研究使用太阳辐射量灌溉控制仪进行水肥管理时，不同水肥供应量对菠菜产量及品质的影响，以期为高效生产优质叶菜类蔬菜的水肥供应方式及供应量提供理论依据与技术支撑。【方法】试验使用太阳辐射量灌溉控制仪进行水肥管理，当太阳辐射量累积值达到设定阈值时会进行定量灌溉，通过该仪器设置4个灌溉区（W1处理低水肥、W2处理中水肥、W3处理高水肥、W4处理中水无肥）和对照W5处理（传统栽培）共5个处理，研究不同水肥量及水肥施用方式对菠菜产量和品质的影响。【结果】W5处理的株高和产量都低于W2处理和W3处理，硝酸盐量、栽培后土壤中NO3--N量和土壤EC值在所有处理中最高。W1处理和W4处理的株高及产量在所有处理中最低，其中W4处理的硝酸盐量、栽培后土壤中NO3--N量和土壤EC值在所有处理中最低。W2处理和W3处理的株高和产量都是所有处理中最高的，W2处理和W3处理之间的株高和产量差异不显著，而W3处理的水肥供应量是W2处理的1.4倍，且W3处理叶片内硝酸盐量是W2处理的1.4倍且差异显著。【结论】综上，使用太阳辐射量灌溉控制仪进行菠菜栽培时，水肥供应方案以W2处理为宜。 |

| Abstract: |
| 【Objective】There have been widespread problems in vegetable production,which were low utilisation of water and fertilizer and environmental pollutionm caused by excessive water and fertilizer supply.In response to such problem, the effects of different water and fertilizer supply levels on the yield and quality of spinach were investigated using spinach as the material and using a solar-radiance-irrigation controller. In order to provide a theoretical basis and technical support for the efficient production of high quality leafy vegetables. 【Method】,The experiment was carried out using a solar radiation irrigation controller for water and fertilizer management. The irrigation was dosed when the accumulated solar radiation reached a set threshold. To study on the effect of different water and fertilizer application methods on the yield and quality of spinach, setting up four zones irrigated by solar-radiance-irrigation controller: fertilizer containing a little water (W1 treatment), fertilizer containing medium plenty of water (W2 treatment), fertilizer containing plenty of water (W3 treatment), medium plenty of water and no fertilizer (W4 treatment), and using conventional cultivation (W5 treatment) as control.【Result】The plant height and yield of W5 treatment were lower than those of W2 treatment and W3 treatment.Meanwhile,W5 treatment had the highest content of nitrate and NO3--N and the highest EC of soil in post-cultivation soil among all treatments. The plant height and yield of W1 treatment and W4 treatment were the lowest among all treatments, with W4 treatment having the lowest nitrate content, post-cultivation soil NO3--N content and EC of soil. W2 treatment and W3 treatment had the highest plant height and yield among all treatments. There were not significant differences in plant height and yield between W2 treatment and W3 treatment , while W3 treatment had 1.4 times more water and fertilizer supply than W2 treatment and the nitrate content in the leaves of W3 treatment was 1.4 times higher than that of W2 treatment.【Conclusion】In summary, it is preferable to the W2 treatment when using the solar-radiance-irrigation controller to cultivate spinach. |
