【摘要】 植物源营养素是以中医农业理论为指导思想,以传统中草药为原料,经现代萃取技术精制而成的一种新型、高效、环保、天然有机植物营养产品。为了解植物源营养素对植物生长的影响,以黄瓜为试材,采用不同浓度的植物源营养素处理,研究其对黄瓜发芽、生长、产量、品质的影响。结果表明:不同浓度的植物源营养素对黄瓜种子发芽和生长影响不同,低浓度(0.2…mg/L)植物源营养素使黄瓜种子发芽率提高12.94%,茎粗、叶面积、叶片鲜重、叶片干重等也分别提高11.43%、145.71%、26.59%和25.79%;高浓度(10…mg/L)植物源营养素抑制黄瓜种子发芽和生长,而且随着浓度的增加抑制作用越明显;植物源营养素根部喷施和叶面喷施都能促进黄瓜生长和提高黄瓜品质,其中根部喷施更有利于黄瓜初期的营养生长和后期的生殖生长,而叶面喷施则有利于黄瓜后期的营养生长。更多还原

【Abstract】 Phytonutrient is a new kind of efficient,environmental and natural organic plant nutrition products based on the theory of traditional Chinese medicine on agriculture. Phytonutrients are extracted from traditional Chinese herbs and refined by modern extraction techniques. In order to study effects of phytonutrients on the seed germination and plant growth,cucumbers were selected as materials for treatments of different phytonutrients concentrations and applications. The results showed that :different concentrations of phytonutrients have different effects on seed germination and growth of cucumber. Low concentration of phytonutrients at 0.2 mg/L,the germination rate of cucumber seeds increased by 12.94%,the growth indexes of cucumber,such as stem diameter,leaf area,fresh weight and dry weight of leaf increased by 11.43%,145.71%,26.59% and 25.79% respectively.High concentration of phytonutrients at 10 mg/L,inhibited the seed germination and growth of cucumber,and the inhibitory effect becomes more obvious as the concentration increased. Phytonutrients promoted the growth ofcucumber plants and improve the fruit quality by using both root spraying and leaf spraying. The root spraying is more beneficial to the early vegetative growth and late reproductive growth of cucumber. The leaf spraying is helpful for the late vegetative growth of cucumber.更多还原
