| [目的]明确自行研制的专用叶面肥对提高黄瓜产量和改善黄瓜经济性状的作用效果.[方法]在设施大棚条件下,设置喷清水(CK)、喷施稀释叶面肥500倍(处理Ⅰ)和1 000(处理Ⅱ)倍液3个处理,于开花期喷施2次,每次喷施清水和叶面肥稀释液750 kg/hm2,通过田间试验测定和比较各处理的黄瓜产量和有关经济性状指标.[结果]与对照相比,开花期喷施该专用叶面肥500倍和1 000倍液,可使瓜长、瓜直径、单瓜质量分别增加9.4%和0.4%,27.3%和17.6,10.33%和5.4%;喷施叶肥可以减少瓜条的变曲及弯曲程度,端直瓜比例分别提高13%和73%;瓜数分别增加57.1%和28.6%,产量(两个试验的平均值)分别提高61.0%和24.9%.喷施叶面肥处理具有显著的增产效果,同时也有效改善了黄瓜的经济性状,从而提高了黄瓜的商品品质.[结论]对不同处理的产量和成本等因素进行综合考虑,以喷施稀释500倍专用叶面肥的增产增收效果最为显著. |

| Abstract: |
| 【Objective】 This study was to make sure of the effect of the foliar fertilizer on the yield and economic characteristics of cucumber.【Method】 Field plot experiments were carried out to study the effects of different treatments which were spraying water（CK），the foliar fertilizer dilution 500 times（TreatmentⅠ） and 1 000 times （Treatment Ⅱ）on the yield and some economic characteristics by spraying 750 kg/hm2 of water and foliar fertilizer dilution every of two times at flowering stage in green house.【Result】 Compared with the control,spaying the foliar fertilizer with dilution 500 times and 1000 times at flowering stage increased the length,width,single weight of cucumber by 9.4% and 0.4%,27.3% and 17.6, 10.33% and 5.4% respectively,and reduced bending and the degree of bending,the straight cucumber rates increased by 13% and 73% respectively;the cucumber number increased by 57.1% and 28.6% respectively;yield (average of two tests) increased by 61.0% and 24.9%.Spraying foliar fertilizer significantly increased yield,and also improved the economic traits of cucumber, resulting in improved quality of cucumber.【Conclusion】 Taking into account the yield,cost and other factors,among the different treatments, spraying the foliar fertilizer dilution 500 times has more obvious effects on yield and income increase than the others. |
