采用单因素随机区组试验设计，在河西灌区试验观察了喷施腐殖酸水溶肥对番茄生长的效果。结果表明，喷施腐殖酸水溶肥能有效改善番茄植株农艺性状和商品性能，可显著促进番茄增产，最佳施用量为每次喷施 1 000倍水溶液750 kg/hm2，从番茄开花期开始喷施，每隔10 d喷1次，连喷4次。

Using a single factor randomized block experimental design， the effect of the amount of water-soluble fertilizer spraying of humic acid on tomato growth was observed in Hexi irrigated area . The results showed that humic acid soluble fertilizer spraying tomato plants can effectively improve the agronomic traits and commodities of tomato plants， can significantly promote tomato yield， the optimum application rate was each 1 000 times spraying an aqueous solution of 750 kg/hm2 from the beginning of flowering tomato， every 10 days spray a second， and even spray four times at intervals .
