大量元素水溶肥(微量元素型)在黄瓜上的应用效果

以“津绿”黄瓜为试材,以青海金地盘现代农业科技有限公司生产的金盘福肥大量元素水溶肥(微量元素型)为肥料,采取田间大区对比的方法,连续2年研究了金盘福肥大量元素水溶肥(18-12-20+TE,18-12-20+TE,25-14-16+TE,15-12-26+TE,20-13-22+TE)对温室黄瓜生物学性状、产量、品质、氮肥偏生产力、土壤硝态氮含量和经济效益的影响,以期为其肥料登记和推广提供依据。结果表明:与常规施肥处理相比,施用金盘福肥处理黄瓜平均株高提高了11cm,平均瓜长提高了0.5cm,平均单瓜质量提高了17g,增产率为8.80%,氮肥用量减少了14.91%,磷肥用量减少了7.43%,钾肥用量减少了18.95%,总糖含量提高了0.14个百分点,维生素C含量提高了13.22mg·kg^-1,氮肥偏生产力提高了27.86%,0~20cm土层硝态氮含量较常规施肥处理提高了17.9mg·kg^-1,20cm以下土层硝态氮含量均低于习惯施肥处理,1hm^2纯收益增收34 650元,投入产出比为1∶7.14。

Application Effects of Macronutrient Water Soluble Fertilizer(Microelement Type)on Cucumber

Taking ‘Jinlyu’ cucumber and Jinpanfufei water soluble fertilizer(microelement type) by Qinghai Jindipan Modern Agricultural Science and Technology Co.Ltd.as materials,a method of field comparison was adopted,the effects of Jinpanfufei water soluble fertilizer (18-12-20+TE,18-12-20+TE,25-14-16+TE,15-12-26+TE,20-13-22+TE) on biological characteristics,yield,quality,PFPN,soil NO-3-N and economic benefits of greenhouse cucumbers for two consecutive years were studied,in order to provide a basis for fertilizer registration and promotion.The results showed that compared with the conventional fertilization treatment,the average plant height of cucumber treated with Jinpanfufei increased by 11 cm,the average melon length increased by 0.5 cm,the average single melon height increased by 17 g,the yield increased by 8.80%,the nitrogen fertilizer usage decreased by 14.91%,the phosphorus fertilizer usage decreased by 7.43%,the potassium fertilizer usage decreased by 18.95%,the total sugar content increased by 0.14 percentage points,the vitamin C content increased by 13.22 mg·kg^-1,PFPN increased by 27.86%,NO3^--N content in 0-20 cm soil layer increased by 17.9 mg·kg^-1 compared with the conventional fertilization treatment,NO-3-N content in soil layer below 20 cm was lower than that in the conventional fertilization treatment,net income increase to 34 650 RMB·hm^-2,input to output ratio was 1∶7.14.
