日光温室番茄滴灌营养液土培试验研究

Study on the Fertigation of Tomato Soil Culture by Drip Irrigation in Greenhouse

通过日光温室番茄滴灌营养液土壤栽培试验，研究了滴灌营养液土壤栽培条件下对番茄生长发育、产量和品质的影响。试验营养液采用日本园试均衡营养液配方，以滴灌条件下，农民习惯采用的施肥量为对照，试验共8个处理。结果表明，各滴灌营养液土壤栽培处理与传统的滴灌施肥处理相比番茄的生长势较强，生育期提前一周左右，全生育期内施肥量减少了23．2％～73％，总产量提高了8．2％～22．8％，同时品质得到改善，果实内硝酸盐含量都显著低于对照处理。

The paper was intended to study the effect on the growth, yield and quality of tomato with fertigation by drip irrigation in greenhouse. The nutrition formula of horticulture experiments plant of Japan was used as treatments＇ and the farmer＇s conventional drip fertilization was used as control. There were 8 treatments in this experiment. The result showed that the nutrition treatments grew stronger, saved more 23.2%-73% fertilizers, produces more 8.2%-22.8% yield than the control. The quality of fruit in the treatments was improved; the contents of NOs in fruit were significantly reduced than CK.
