两种含腐植酸液体肥对番茄农艺性状及产量的影响

Eff ects of Two Kinds of Liquid Fertilizers Containing Humic Acid on Agronomic Characters and Yield of Tomato

为探明分别以矿源黄腐酸钾和生化黄腐酸钾为原料的两种含腐植酸液体肥对番茄农艺性状及产量的影响,采用大棚试验,设置含腐植酸液体肥1(T1)、含腐植酸液体肥2(T2)2个试验处理,测定番茄不同生育期植株叶绿素含量、株高、茎粗、产量等指标。结果表明:与T2处理相比,T1处理可显著增加结果期番茄叶绿素含量,显著提高苗期和结果期番茄株高,提高开花坐果期番茄单株花数、单株果数,显著提高结果期番茄茎粗和单株果数;在可溶性固形物含量方面,T1处理和T2处理差异不显著;在果径方面,T1处理较T2处理可显著提高番茄果径;从产量和经济效益来看,T1处理较T2处理显著增产7.3%,节本增效1.33万元/hm^(2)。

In order to investigate the ef fects of two kinds of liquid fertilizers containing humic acid on the agronomic characters and yield of tomatoes, greenhouse tests with two test treatments of liquid fertilizer containing humic acid 1(T1) and liquid fertilizer containing humic acid 2(T2) were conducted using mineral source potassium fulvate and biochemistry potassium fulvate as raw materials to determine the chlorophyll content, plant height, stem thickness and yield of tomatoes at dif ferent growth stages.The results showed that: compared with T2 treatment, T1 treatment could significantly increase the chlorophyll content of tomato at the fruiting stage, plant height of tomato at seedling stage and fruiting stage, the fl owers number and fruits number of tomato plants at the fl owering and fruiting stage, and the stem thickness and fruit number of tomato plants at the fruiting stage. There was no signifi cant dif ference between T1 treatment and T2 treatment in terms of soluble solids content of tomato. In terms of fruit diameter, T1 treatment could signifi cantly improve tomato fruit diameter compared with T2 treatment.From the perspective of yield and economic benefi ts, the yield of T1 treatment was 7.3% higher than T2treatment that inceased of 13300 yuan/hm^(2).
