高浓度腐植酸水溶肥在大蒜上的冲施效果研究

Application Effects of High Concentration Humic Acid Water-soluble Fertilizer on Garlic

以大蒜为供试作物,采用大田种植方式,研究了高浓度腐植酸水溶肥对大蒜产量及农艺性状的影响。结果表明,全程使用高浓度腐植酸水溶肥4次,不同生长期植株各农艺性状均与对照组存在明显差异;使用组大蒜平均产量比对照组增加575.49 kg/亩,以当时市场收购价平均净收益增加2573.23元/亩;同时,使用组大蒜平均直径在60~70 mm的占比达到59.67%,对照组仅为30.99%;使用组大蒜平均单颗重在0.15~0.25 g的占比高达74.33%,大于0.25 g以上占比为16.34%,而对照组大蒜平均单颗重主要在0.15 g以下,占比达到63.00%。因此,全程使用高浓度腐植酸水溶肥的大蒜产量和农艺性状均显著提升,经济效益可观。

Using garlic as the experimental crop and field cultivation,the effects of high concentration humic acid water-soluble fertilizer on garlic yield and agronomic characters were studied.The results showed that the whole process of using high concentration humic acid water-soluble fertilizer 4 times,there were significant diff erences in agronomic traits between plants of diff erent growth stages and the control group.The average yield of wet garlic in the use group increased by 575.49 kg/667 m^(2) compared to the control group,and the average net profit increased by 2573.23 yuan/667 m^(2) at the market purchase price at that time.At the same time,the proportion of garlic with an average diameter of 60~70 mm in the use group reached 59.67%,while that in the control group was only 30.99%.The proportion of average single particle weight of 0.15~0.25 g in the use group was as high as 74.33%,and the proportion of average single particle weight greater than 0.25 g was 16.34%,while the average single particle weight in the control group was mainly below 0.15 g,accounting for 63%.Therefore,the use of high concentration humic acid water-soluble fertilizer throughout the process significantly improved garlic yield and agronomic traits,leading to a significant increase in economic benefits.
