灌溉方式对梨园土壤水分及产量品质的影响
Effects of irrigation methods on soil moisture and fruit production of the pear orchard
摘要
Abstract
Furrow irrigation, ridge irrigation, drip irrigation, micro-sprinkler irrigation and non-irrigation(CK) were performed to investigate the influences of different irrigation methods on soil moisture, photosynthesis, yield and fruit quality in pear orchard, to selecte the appropriate water-saving irrigation technology. The results showed that: (1) Micro-sprinkler irrigation led the highest soil moisture content in 0 ~ 60 cm soil layers, followed by drip irrigation, ridge irriga-tion, furrow irrigation and CK, micro-sprinkler irrigation's water storage capacity was significantly higher than other irri-gation methods; (2) The order of net photosynthetic rate performance was micro-sprinkler irrigation≥ drip irrigation≥ ridge irrigation > furrow irrigation > CK, which showed that micro-sprinkler irrigation treatment of pear leaf photosynthetic capacity was the strongest, followed by drip irrigation; (3) The yield of micro-irrigation was the best, followed by drip irrigation, compared with controls, yield per plant rised by 54.98% and 44.18%; (4) Besides, micro-sprinkler irriga-tion and drip irrigation could also raise the fruit quality, such as bigger fruit size, higher content of soluble solids and to-tal soluble sugars, lower fruit firmness, lower content of acid and stone cell. It is concluded that, micro-sprinkler irriga-tion can improve the soil moisture condition and increase the ability of photosynthesis and result in higher yield and fruit quality more significantly than others, which is an ideal water-saving irrigation technology.关键词
