| In order to improve the quality and yield of Chenzhou tobacco in magnesium, manganese, molybdenum, boron, low level of soil in the experiment, the use of tobacco in Chenzhou add magnesium fertilizer on, boron, manganese, molybdenum fertilizer and manure application four with 10 different combinations of tobacco agronomic traits, quality, production, production and chemical composition of tobacco effects. Research results show that:1. Chenzhou Tobacco most of soil nutrients in the appropriate range, but the general lack of Mg, B; 20% of the soil lacking Mn; 32.18% of the soil lacking Mo; fertilization process in tobacco control should pay attention to N complement K, Mg, B fertilizer, some tobacco area complement Mn, Mo fertilizer.2.Only trace elements fertilizer experiment results show that the test conditions, the appropriate magnesium, manganese, boron, molybdenum fertilizer could improve tobacco plant, looks for the tobacco is, among agronomic traits such as plant height, stem, leaf number, leaf size effectively is improved to varying degrees, stronger.the yield, output, leaves, and the average weight ratio on secondary smoke increased to stronger.the yield, classy smoke ratio, average price index has obviously improved, Tobacco leaf corresponding nutrient content in different degree, total sugar, protein, nicotine, total nitrogen content and main chemical compositions, etc ShiMuKe value, sugar, alkali, nitrogen than alkali etc intrinsic quality status of tobacco leaf quality requirements, tends to be obviously improve the inner quality. With the dilution of RMB 1000 times "good di boron 90L" PengFei effect, tobacco production for 153.92 kg, value for 2361.15 yuan, the ratio of secondary smoke than low boron,92.9 yield increases of 6.55 kg, respectively 172.77 yuan, the output value; the proportion of secondary smoke 6.3 percent ShiMei, boron, manganese, molybdenum fertilizer moderation, shortage or excessive will yield, quality and value.3.Fertilizer trace elements fertilizer experiment results show that the test conditions and different amount of trace elements fertilizer could improve tobacco plants grow, and looks than only the corresponding Mg, Mn, Mo fertilizer B, the effect is better, and the collocation of different kinds of trace elements to improve the effect of tobacco plants grow looks better, for tobacco agronomic traits such as plant height, stem, leaf number, leaf size effectively is improved to varying degrees, stronger.the yield, output, leaves, and the average weight ratio on secondary smoke increased to stronger.the yield, classy smoke ratio, average price index has obviously improved, Tobacco leaf corresponding nutrient content in different degree, total sugar, protein, nicotine, total nitrogen content and main chemical compositions, etc ShiMuKe value, sugar, alkali, nitrogen than alkali etc intrinsic quality status of tobacco leaf quality requirements, tends to be obviously improve the inner quality. Which of the RMB and magnesium sulfate, dilute 10kg,100 times of "hao di B", dilute sulphuric acid manganese and 100 times of 50 times diluted ammonium molybdate production for the best effect, tobacco 172.88 kg, value for 2686.58 yuan, the ratio of secondary smoke envelop, compared with the increased production 26.17 kg, respectively 494.8 yuan, the output medium smoke 8.1% proportion. |
