环境因子远程监测技术对枸杞园土壤水分动态变化规律的影响

以宁杞7号为研究对象,设置精准滴灌区(PI)和常规滴灌区(CI)2个水肥处理,研究降雨、土壤温度、滴灌对枸杞园土壤水分动态变化规律的影响,以及不同水肥处理对枸杞产量的影响。结果表明,该地区降雨对枸杞园表层土壤水分影响较大,对50 cm土层土壤水分影响不大;土壤温度与土壤水分成负相关的关系,滴灌水量在短时间内可以调节土壤温度;2种水肥处理土壤水分动态变化规律具有一致性,土壤水分含量主要受滴灌量的影响较大,CI处理土壤水分变化范围为15%～35%,PI处理土壤水分变化范围为5%～20%,CI处理各土层土壤水分明显高于PI处理;PI处理较CI处理增产13.3%,节本增效3.12万元/hm~2。

The Influence of Remote Monitoring Technology of Environmental Factors on Dynamic Change of Soil Moisture in Wolfberry garden

Taking L.barbarum No.7 as the research object, two water and fertilizer treatments, namely precise drip irrigation area and conventional drip irrigation area, were set up to study the influence of rainfall, soil temperature and drip irrigation on the dynamic change rule of soil moisture in Chinese wolfberry garden, and the influence of different water and fertilizer treatments on the yield of Chinese wolfberry. The results showed that rainfall in this area had a great influence on the surface soil moisture of the wolfberry garden, while the soil moisture in the 50cm soil layer had little influence. There was a negative correlation between soil temperature and soil moisture. Drip irrigation could regulate soil temperature in a short time. The dynamic change rules of soil moisture in the two water and fertilizer treatments are consistent, and the soil moisture content is mainly influenced by drip irrigation. The variation range of soil moisture in CI treatment is 15%~35%, while that in PI treatment is 5%~20%. The soil moisture in CI treatment is significantly higher than that in PI treatment. The yield of PI treatment was higher than that of CI treatment, with a yield increase rate of 11.8%, saving 7,800 yuan /hm2.
