大田滴灌条件下,通过设置常规滴灌对照(CK)、250 mT磁化处理水滴灌(T250)和300 mT磁化处理水滴灌(T300)3个处理,研究了不同磁强磁化水滴灌对加工番茄生长发育、养分吸收及产量的影响。磁化水滴灌能够促进加工番茄的生长发育、生物量以及干物质累积。坐果中期和收获期磁化处理的干物质量比对照分别增加6.9%~16.9%和8.7%~21.2%;加工番茄小果数(φ<10 mm)和大果数(φ≥10 mm)也比对照分别增加23.7%~25.0%和7.3%~12.5%。磁化水灌溉可明显改善加工番茄的N、K营养,收获期加工番茄植株单株N、K吸收量分别为1.7~1.9 g株和3.9~4.0 g株,与CK相比分别提高了23.5%~42.2%和30.9%~33.1%。磁场强度为300 mT磁化水处理的番茄产量为142 065 kghm2,显著高于对照的129 885 kghm2,增产9.4%。磁场强度为300 mT磁化水滴灌对促进加工番茄的生长发育、改善养分吸收和提高加工番茄产量有明显作用。
Under the conditions of field drip irrigation, three treatments, conventional drip irrigation (CK), 250 mT magnetized water drip irrigation (T250) and 300 mT magnetized water drip irrigation (T300), were conducted to study the effects of drip irrigation with magnetized water of different intensities on the growth and development of processed tomato , Nutrient uptake and yield impact. Magnetized water drip irrigation can promote processing tomato growth and development, biomass and dry matter accumulation. Compared with the control, the dry matter mass of the magnetization in the mid-stage and harvesting phases increased by 6.9% -16.9% and 8.7% -21.2%, respectively. The small fruit number (φ <10 mm) and fruit number (φ≥10 mm) Respectively, an increase of 23.7% ~ 25.0% and 7.3% ~ 12.5%. Magnetized water irrigation can significantly improve N and K nutrition of processed tomato, and the N and K uptake per plant of the processed tomato plants at the harvest stage were 1.7 ~ 1.9 g and 3.9 ~ 4.0 g respectively, which were increased by 23.5 % ~ 42.2% and 30.9% ~ 33.1%. The yield of tomato with magnetic field intensity of 300 mT magnetized water was 142 065 kghm2, which was significantly higher than that of the control 129 885 kghm2 with a yield increase of 9.4%. Magnetic field strength of 300 mT magnetized water drip irrigation to promote the growth and development of processed tomato, improve nutrient absorption and improve the processing of tomato yield has a significant role.
