不同复配基质对盆栽荆芥生长及品质的影响

Effects of Different Compound Substrates on the Growth and Quality of Herba schizonepetae in Pots

【目的】研究不同复配基质对盆栽荆芥生长及品质的影响,筛选出适宜盆栽荆芥的复配基质。【方法】以大叶荆芥为材料,通过在草炭、椰糠中添加一定比例的珍珠岩、蛭石复配成栽培基质,研究不同复配基质的理化性质以及对盆栽荆芥生长与品质的影响,运用模糊隶属函数法综合分析不同复配基质的盆栽荆芥。【结果】T 2处理(草炭∶椰糠=2∶1)荆芥的株高、全株鲜质量最大,分别为29.35 cm、10.42 g,可溶性糖含量、VC含量最大,分别为2.19%、0.25 mg/g,隶属函数平均值最大,为0.67,综合评价最高。【结论】盆栽荆芥在基质中添加一定比例的椰糠可以达到部分替代草炭的目的,促进荆芥的生长,改善荆芥的品质。采用T 2处理进行荆芥的复配基质盆栽。

【Objective】To explore the effects of different compound substrates on the growth and quality of Herba schizonepetae in pot cultivation and select the suitable compound substrates for the plant in pot cultivation.【Methods】The experiment used Big leaf Herba schizonepetae as the testing materials by adding a proportion of perlite,vermiculite to the charcoal and coconut bran,studied the physical and chemical properties on the growth and quality of different compound matrix,analyzed the physical and chemical properties of different mixed substrates and its effects on the potted Herba schizonepetae growth and quality by using the method of fuzzy membership function of different distribution matrix of Herba schizonepetae plants for comprehensive analysis.【Results】T 2 treatment(peat∶coconut bran=2∶1)had the highest plant height and fresh weight(29.35 cm and 10.42 g,respectively),the highest soluble sugar content and vitamin C content were 2.19%and 0.25 mg/g,respectively.The average value of the member function was the highest,which was 0.67,and the comprehensive evaluation result was also the highest.【Conclusion】Adding a certain proportion of coconut bran in the matrix of potted Herba schizonepetae can partially replace peat,promote its growth and improve the quality.According to the comprehensive comparison and analysis of yield,quality and other indexes of potted Herba schizonepetae,T 2 treatment is recommended for the potted Herba schizonepetae.
