Low-grade Cigarette Specialty Materials For Cultivating Techniques

Tobacco is an important economic crop in China, and the main production mode of tobacco are high-quality tobacco production, quality tobacco production and high-quality filler production in our country. Because the demand for cigarette brand development, They need a certain amount of the discarded tobacco supply, so it is necessary to carry out the discarded tobacco cultivation techniques. The results show that:1. Presently, Current cultivars have K326, yun 85 and yun 87, thereinto K326 with the strong fertilizer response ability and higher yield,accord with the needs of the discarded tobacco leaf production.In the multi-leaf type varieties, HY-CT, YZ-20-6 and HF61 accord with the demands of the discarded tobacco leaf yields and quality. YH06, YH15 and Longjiang 917 can be used for options.2. K326 variety of raw materials as a discarded tobacco cultivation, the fertilizer dosage in 8.0-8.5kg/666.7m2, the appearance quality of flue-cured tobacco leaf are good.3. The results show that:HF61 N fertilizer usage is broad, the N usage during 7.6-9.05kg/666.7m2 can get better economic benefit.4. The results show that:when HF61, K326 variety were be used in the discarded tobacco leaf cultivation, the planting density was about 1100 per plant suitable 666.7m2.5. The results show that:when HY-CT, K326 variety were be used in the discarded tobacco leaf cultivation, and retention of a second topping and keeping one pitchfork can achieve better quality and meet the quality requirements of the discarded tobacco leaf.
