Effects of Microbial Fertilizer and Humic Acid Compound Fertilizer on Growth and Photosynthetic Characteristics of Lilium
摘要
Abstract
In order to explore the effects of microbial fertilizer and humic acid compound fertilizer on the growth,photosynthetic characteristics,and bulb quality of Lilium,and to determine suitable fertilization amounts,a field micro-plot experiment was conducted using Lilium tissue-cultured seedlings.8 treatments were set up,including humic acid compound fertilizer at 10(F-1),30(F-2),50 g·m-2(F-3),microbial fertilizer at 30(J-1),60(J-2),90 g·m-2(J-3),humic acid compound fertilizer 30 g·m-2+microbial fertilizer 30 g·m-2(H),and a water control(CK).The effects of different treatments on the growth and photosynthetic characteristics of Lilium plants were compared and analyzed.The results showed that,compared with CK,the application of microbial fertilizer and humic acid compound fertilizer promoted the growth and development of both the aboveground and underground parts of Lilium to varying degrees.Among them,the H treatment significantly increased the circumference,fresh weight,root length,number of lateral roots and stem thickness of Lilium bulbs,which were 1.76,3.78,1.61,1.85 and 1.58 times that of CK,respectively.The application of microbial fertilizer and humic acid compound fertilizer significantly increased the chlorophyll content and net photosynthetic rate(Pn)of Lilium,with the H treatment having the highest chlorophyll a and chlorophyll b contents,which were 2.31 and 2.64 times that of CK,respectively,and the Pn of J-2 and J-3 treatments being the highest,148.72%and 172.96%higher than that of CK.The stomatal conductance(Gs),transpiration rate(Tr)and water use efficiency(WUE)of the microbial fertilizer-treated plants were significantly increased compared to CK,while the intercellular CO2 concentration(Ci)was significantly reduced,with the Gs and Tr of J-2 treatment being the highest,50.00%and 65.47%higher than that of CK.The application of microbial fertilizer and humic acid compound fertilizer effectively increased the sucrose,starch,and soluble protein contents of Lilium bulbs,with the sucrose and protein contents of F-3 treatment being the highest,and the starch content of J-3 treatment being the highest,increasing by 17.97%,15.41%and 9.20%compared to CK,respectively.Through principal component analysis and membership function analysis,it was concluded that the comprehensive evaluation of Lilium indicators was best under H treatment.In summary,microbial fertilizer and humic acid compound fertilizer could effectively promote the growth and photosynthetic rate of Lilium,and improve the yield and quality of bulbs.When both were combined,the growth effect on Lilium ws the best.Above results provided a theoretical basis and technical support for the fertilization of Lilium bulbs.关键词
