中期施肥对栝楼果实产量与品质的影响

通过6种化肥的大田试验,探讨了中期施肥对栝楼果实产量、质量、浸出物、可溶性糖、粗多糖和灰分含量的影响.结果表明:磷酸二铵和硫酸钾复合肥对栝楼果实产量增长作用显著,较对照分别增加了104.7％和79.86％；磷酸二铵、硫酸钾复合肥、硫酸钾和磷酸二氢钾对栝楼果实水溶性浸出物含量增加具有一定作用；6种化肥均对醇浸出物含量有不...

Effect of mid-term applying fertilizer on yield and quality of Trichosanthes kirilowii Maxim

To evaluate mid-term fertilization on Trichosanthes fruit yield and quality,six different kinds of special fertilizer were tested in field.The fruit yield,weight,extract,sugar and ash content were determined.Application with diammonium phosphate and potassium sulfate compound fertilizer caused a marked rise in the yield of Trichosanthes kirilowii and increased by 104.7% and 79.86% respectively,compared with the control.Diammonium phosphate,potassium sulfate compound fertilizer,potassium sulfate and potassium dihydrogen phosphate had a certain effects on the contents of water extracts.Application of the six kinds of fertilizer was benefit to alcohol extract content growth,but was not good for the accumulation of fat-soluble components and sugar.Fertilization could increase the content of physical ash,but had little effect on acid insoluble ash.The field experiment results showed that organic fertilizer combined application of N,P,K fertilizer were the good special fertilizer for Trichosanthes kirilowii to meet the nutritional needs of each growth stages.
