摘要
为了探明保水剂(SAP)、黄腐酸(FA)两种化学制剂联合调控对设施番茄生长和水分利用效率的影响,根据施用SAP、FA的不同组合及灌溉定额的不同设置了:S、F、SF、SFL、CK 5个处理,进行了对比试验。结果表明:SAP和FA能显著促进番茄生长、提高土壤含水率、产量和水分利用效率。在灌水相同的情况下整个生育期内SF处理的土壤含水率最高,较S、F、CK处理平均增加5.0%、10.6%、17.0%;S、F处理较对照处理CK分别提高13.0%、4.0%。SF处理的产量最高为111.8 t/hm~2,较S、F、CK处理增加8.6%、6.8%、14.1%。SFL处理较其他处理少灌一次水,产量为110.6 t/hm~2,增产12.9%,水分利用效率最高,为50.3 kg/m~3,较CK处理提高23.1%。SAP和FA联合调控的蓄水保墒和增产效果显著。
In order to explore the effects of the combined regulation of two chemical agents, SAP and fulvic acid, on the growth and water use efficiency of greenhouse tomato plants, 5 treatments were set according to the different combinations of SAP and FA and irrigation quota, including S, F, SF, SFL and CK. The results showed that: SAP and FA could significantly promote tomato growth, increase soil moisture content, yield and water use efficiency; under the same irrigation condition, the soil moisture content of SF treatment in the whole growth period was the highest, with an average increase of 5.0%, 10.6% and 17.0% compared with that of S, F and CK treatment; the soil moisture content of S and F treatment were 13.0% and 4.0% higher than that of CK treatment, respectively; the maximum yield of SF treatment was 111.8 t/hm~2, which increased by 8.6%, 6.8% and 14.1% compared with S, F and CK treatment; compared with other treatments, SFL treatment used less irrigation water, resulting in a yield of 110.6 t/hm~2 and an increase of 12.9%, with the highest water use efficiency(50.3 kg/m~3) and a 23.1% increase compared with CK treatment. The combined regulation of SAP and FA can control water conservation and increase yield effectively.
