Different Effects of seeding and fertilizing of the new strain LY-1 tobacco yield and quality

667m Shi N10kg. 2 Results and analysis 2.1 A treatment growth period after transplanting the temperature is too low, despite the use of plastic film mulching cultivation, Received date :2007-06 ~ 26 Author: Qi Yan Ke, male, born in 1971, agronomist. Table 1LY-1 fertilization in each treatment (unit: kg/667m2),[link widoczny dla zalogowanych], but seedling growth is slow, March 3 after the frost leaves the top of the plastic film, part of the cold; and B deal with the top of the film less of Tobacco , cold and light; C treatment after transplanting climatic conditions can meet the needs of growth of tobacco plant. The same sowing date on growth of different fertilizer treatments not significantly different, analysis of the reasons may be the high rainfall (April-June 2006, the county field rainfall 877.6mm, rainfall over the same period in 2004, 1.95 times), in particular, is late May to early June several heavy rainfall, resulting in more serious loss of fertilizer leaching. A, B Comparison of two treatments with the K326, K326 5d squaring around of early and effective leaves only 15 or so, is obviously insufficient,[link widoczny dla zalogowanych], after topping discretion reserves the right to shoot four or so of normal mining baked lower leaves. LY-1 in different seeding time spent dealing with the phenomenon did not occur earlier, indicating that non-performing LY-1 has strong resistance to the environment. C treatment compared with the control line K326 budding stage. C parietal maturity for the July deal 8El, were made after rice in the local tobacco rhythm on July 10 adopted the end of baking to ensure the bypass was made after the cold heading of rice. 2.2 The main diseases seen from Table 2, the processing mosaic disease (CMV, TMV) incidence rate was 0. Brown spot disease incidence was 7.8% a 15.6% disease index was 1.77-4.42; its incidence, disease index with the same seeding period, no significant difference between different fertilization treatment. Black stem disease incidence rate of 2% to 12%, disease refers to 0.5-30, the incidence to a lesser extent, on leaf 3, 2008 1 Du Tour Aunt 61 t yield and quality of oblique small. Table 1 2LY a comparative test of the occurrence of major diseases Note: mosaic disease,[link widoczny dla zalogowanych], brown spot and black stem disease survey dates were May 10, June 26, June 30. 2.3 The main agronomic traits seen from Table 3, I-1 in different seeding time, different fertilizer treatment compared with the same period of K326, its leaf area was significantly larger than the waist K326. Late sowing has increased plant height, leaf number of trends. Table 1 3LY a comparative test of tobacco products 2.4 agronomic traits, quality seen from Table 4, three deal with different sowing dates increased with N applied, yield, value and proportion of superior tobacco was increasing. Among them, the sowing date was November 30, each 667m (below) the amount of applied N treatment of tobacco for the highest yield of 10kg, up to 154.93kg, compared with the same amount of 8-sowing treatment facilities increase N 14.20, an increase of rates 10.09%; than November 10 sowing, nitrogen yield the same treatment 12.73kg, increase rate was 8.95%. The proportion of secondary smoke in the previous sowing on November 20, the amount of applied N treatment 10kg highest percentage of 97.15%. Table 1 compares the test 4LY a major economic traits Note: The table space of 667rn. 3 Summary and discussion 3.1 in 3 different sowing treatments, sowing date of 10 November the deal, in February 10 after transplanting at 13.0 ~ 14.4cc long low-temperature weather for up to 40d phenomenon does not appear early flowering, indicating that LY 1 on the adverse external environment of a strong resistance to. In 2006, climatic conditions, early sowing yield, quality is not ideal, late sowing late to consider the root disease, brown spot of the high mountain made after smoke should also be considered the safety of heading date in rice, from the results of seeding that Fujian tobacco planting to November 20 is appropriate. 3.2 in different planting period, the yield of different nitrogen treatment, the quality difference is not obvious, because the growing season may encounter heavy rain several times, resulting in the loss of fertilizer leaching. In the local ecological conditions, the medium fertility field suggested that each 667m. The amount of applied N 8 ~ 9kg, late transplanting tobacco fields as appropriate, should control the amount of nitrogen in order to ensure timely and yellowing of upper leaves mature. 3.3LY an area of more than 1 leaf K326, recommended the full implementation of the planting rows wide and narrow lines of cultivation methods, the implementation of spacing 1.25 ~ 1.30m, spacing 0.5m, to facilitate farm operations,[link widoczny dla zalogowanych], to improve the middle and lower leaf air and light conditions, reduce disease, improve the quality of tobacco. 3.4 By 2003 to 2006 seriously ill in Sanming District mosaic disease field demonstration plant, LY-1 were highly resistant to mosaic disease, it is proposed to further improve its cultivation, baking supporting technology,[link widoczny dla zalogowanych], and in the tobacco industry recognized the strain of chemical Comments on quality ingredients and based on the extended model.
