黄山贡菊叶面肥种类筛选试验OA

This study employed virus free white Gongju from Huangshan as the experimental subject,utilising a randomised block design with 5 foliar fertiliser treatments:treatment A:clear water spray(CK,control);treatment B:spray of trace element water-soluble fertiliser;treatment C:spray of trace element foliar fertiliser;treatment D:spray of multifunctional disease-resistant nutrient solution(photosynthetic bacteria agent);treatment E:spray of amino acid-containing water-soluble fertiliser.Through field plot trials,the effects of different foliar fertilisers on the growth characteristics,yield,and output value of Gongju were investigated.Results indicated that,compared to treatment A,all 4 tested foliar fertilisers improved Gongju agronomic traits to varying degrees while enhancing yield and output value.treatment B achieved the highest output value at 157 690 yuan per hectare.Further analysis revealed treatment B produced the tallest plants at 78.4 cm,the highest number of flowers per plant at 239.1;and a corresponding yield of 1 213.0 kg/hm2,representing an increase of 170.0 kg/hm2(16.3%)over treatment A.The application of trace element water-soluble fertilisers via foliar spraying is recommended for production.This study provides reference for the rational selection and application of foliar fertilisers in Huangshan Gongju cultivation.
