Problems solved by technology

Compared with regular oriental tobacco, regenerated oriental tobacco has more side branches and smaller leaves, but due to the delayed growth period, good water conditions in the middle and late stages of growth, high temperature, and high photosynthetic rate of leaves, if its growth and development are not controlled, its yield will be lower. will be higher, and the quality of tobacco leaves is difficult to meet the raw material quality requirements of industrial enterprises

Abstract

The invention discloses a cultivation method of a regenerative oriental tobacco. The cultivation method comprises the following steps: 1) truncating, reserving stems, 2) replenishing fertilizers, 3) picking bud, reserving branches, 4) reasonably irrigating, 5) promoting ripening, 6) harvesting in batches. The cultivation method is scientific and reasonable, and not only effectively realizes the cultivation of the regenerative oriental tobacco, but also promotes the yield level of the regenerative oriental tobacco to 95-110 kg / mu, reaching 70%-80% of the yield of the oriental tobacco in season.The production level of the regenerative oriental tobacco reaches 65%-75% of the production of the oriental tobacco in season. According to the cultivation method of the regenerative oriental tobacco, reasonable replenishment of fertilizers according to the fertility condition of the oriental tobacco planting soil not only effectively promotes the growth of the regenerative tobacco, but also effectively utilizes the residual fertility of the original oriental tobacco, reduces the cost and enhances the economic benefits.

Description

technical field [0001] The invention belongs to the technical field of tobacco cultivation, and in particular relates to a cultivation method for regenerated oriental tobacco. Background technique [0002] Oriented tobacco is a kind of sun-cured tobacco with small leaves and unique flavor. Botanically, it is a variant of Nicotiana safflower. Because it is mainly grown and planted in the Middle East, it is called oriental tobacco (oriental tobacco) by Westerners. Oriented tobacco leaves have a special aroma, mellow taste, easy to burn, and strong filling power. It is an important raw material for mixed cigarettes and some tobacco products. Therefore, although oriental tobacco accounts for the smallest proportion among the three types of tobacco (flue-cured tobacco, burley tobacco and oriental tobacco), it is also highly valued by the world tobacco industry. [0003] However, due to the large fluctuations in the price of oriental tobacco in the world, a large number of toba...
