经３年连续试验表明：盆栽试验６～４８ｋｇ／６６７ｍ~２的地膜残留量对茄子株高、茎粗和叶面积基本无影响。对根系增长量的影响大于地上部，随着残留量的增加＂根冠比＂值有上升趋势但未达显著水平。对氮、磷、钾吸收的影响仅在Ｐ_２Ｏ_５上有差别。田间试验表明：残留量在３～９６ｋｇ／６６７ｍ~２范围内不论早期产量、总产量还是采收果数仅差０．９％～１．５％。
After three years of continuous trials showed that: pot experiment 6 ~ 48kg / 667m ~ 2 residual film on the eggplant height, stem diameter and leaf area basically no effect. The effect of root growth was greater than that of aerial part. With the increase of residual amount, the ratio of root / shoot increased but did not reach significant level. The effects on N, P and K uptake were only different on P_2O_5. Field experiments showed that no matter the early yield, the total yield or the harvested fruit number was only 0.9% ~ 1.5% in the range of 3 ~ 96kg / 667m ~ 2.
