以“佳粉18号”番茄为试材,研究了不同基肥施入水平与施入深度对大棚番茄产量、干物质积累量以及不同生育时期番茄果实品质的影响。结果表明:番茄产量随着基肥施入总量的增加而增加,但基肥施入总量较高时果实品质较差,其中表层与底层土壤均施入N 1 200kg/hm2、K 600kg/hm2、P 600kg/hm2的基肥水平下番茄产量最高,但果实品质最差;在基肥总量相同的情况下,表层与底层均施肥处理的番茄产量、品质与根系活力要高于仅表层的基肥处理,其中产量与生物量积累分别提高了14.13%与13.53%。试验结果表明,分别在表层与底层土壤施入N600kg/hm2、K 300kg/hm2、P 300kg/hm2的基肥水平更有利于在维持较高的番茄产量水平下提高番茄果实的品质。
The effects of different basal application levels and applied depth on tomato yield, dry matter accumulation and tomato fruit quality at different growth stages were studied using “Jiafen 18 ” tomato as test material. The results showed that the yield of tomato increased with the increase of the total amount of basal fertilizer, but the quality of the basal fertilizer was poor when the total amount of basal fertilizer applied was higher. The contents of N 1 200kg / hm2, K 600kg / hm2, P 600kg / hm2 had the highest yield of tomato under the basal fertilizer level, but the fruit quality was the worst. Under the same total amount of base fertilizer, the yield, quality and root vigor of tomato treated with surface and bottom fertilizers were higher than that of the basal fertilizer alone, The yield and biomass accumulation increased by 14.13% and 13.53% respectively. The results showed that basal fertilizer levels of N600kg / hm2, K300kg / hm2, and P300kg / hm2 applied to the top and bottom soils were more favorable for improving the quality of tomato fruits while maintaining high tomato yield.
