Slightly higher content of 1.68%. The tobacco smell, taste,timberland shoes, irritation and physical strength of the Department performed well,Moncler pas cher, reaching the standards of high quality tobacco. 2,1:2, the relationship between per-mu yield and density can be seen from Table 3, the two-year pilot ● _ results show: a single leaf weight decreased with increasing density, yield per mu increased with density.

If the number of leaves will stay down to the appropriate number of pieces, with per mu will be The decrease, according to the 1994 meeting San tests (Table 3) suggested, C4 per mu yield of close to or deal with high quality tobacco compliance standards. 3 Conclusion baked Guo understand the internal main chemical composition, yield and plant density, different fertilization treatments relations in guiding tobacco production, improve the quality of flue-cured tobacco and cigarette industry on the domestic demand for high quality tobacco is very important. Test results show that: the best cut tobacco planting density is 1212 acres, line spacing, spacing Im 0.55m. in the nitrogen phosphorus and potassium ratio of 1:2:3, based on the best type of fertilizer for the C4 Mushi 1000kg manure (with pure nitrogen 3kg), 25% soybean fat (continued on page 20) More articles related to topics： tory burch sale Yuxi City, the causes of agricultu christian louboutin pas cher Focused on promoting ugg schuhe Common Diseases of Yunnan Province and |
