防御低温育苗技术对烤烟一些酶活性及烟叶经济性状的影响
Effects of defense technique for low-temperature seedling production on enzymatic activity and economic characters of flue-cured tobacco
摘要
Abstract
Effects of low-temperature defense seedling production technique on physiological characters, yield and quality of flue-cured tobacco were studied by using a new tobacco line Huayan06 as experimental material. The objective to find solution to avoid low temperature damage in tobacco seedling production in northern and eastern Guangdong tobacco-planting area Results showed that compared with normal seedlings, low-temperature defense seedling technique could obviously improve activities of nitrate reductase, invertase, and amylase of leaf after transplant. Content of total sugar, reductive sugar, K, total nitrogen, nicotine, and protein content of flue-cured tobacco leaf increased, while content of starch decreased. Yield, output value, average price and percentage of high quality tobacco cultivated this way were all better than those by normal practice. At the same time, adding fermentation agent to substrate had a favorable effect on temperature increase. The best effect was obtained by laying 2 kg rice straw and 24 kg peanut press pulp under seedbed combined with adding fermentation agent, which could be rapidly popularized in large tobacco-planting areas.关键词
