Embodiment Construction

[0023] The present invention will be further described below.

[0024] A kind of grafting and cultivating method of tobacco of the present invention is carried out in the smoking area of ​​Xingwen County, Yibin City, Sichuan Province, and the method comprises the following steps:

[0025] (1) The air-dried tobacco variety Shiyan No. 1 with strong resistance to diseases and insect pests was selected as the rootstock, and the flue-cured tobacco variety KRK26, which was susceptible to diseases and had good quality, was selected as the scion.

[0026] (2) The rootstock is sown 7-10 days earlier than the scion, the seedling age of the rootstock and the scion is 45-60 days, the stem height is 6-10cm, and the stem circumference is 1.3-1.8cm.

[0027] (3) The temperature of the grafting workplace is 15-30 ° C, the humidity is above 50%, and spray with 2-3% bleaching powder aqueous solution, ventilated and dried; the grafting tool blade is soaked in 2-3% chlorine dioxide aqueous soluti...

Abstract

The invention belongs to the technical field of tobacco cultivation and particularly relates to a grafting cultivation method of tobacco. The method includes the following steps that s1, a stock and a scion are selected; s2, a grafting place and tools are selected; s3, tobacco seedling grafting is carried out, wherein redundant leaves of the stock are removed, only core leaves are left, the scion is inserted into a stock splitting opening, and a self-made adhesive is smeared to a grafting wound; s4, grafted seedling management is carried out, wherein leaf fertilizer is sprayed three times every day till the wound of a grafted seedling heals, a stock growth point is removed after the wound heals 3-5 days later, ventilation is carried out and illumination is increased gradually 6-8 days later, and then normal wetting seedling nursing management is carried out. The grafting cultivation method of the tobacco has the advantages of being low in grafting cost, short in management and protection period of the grafted seedling, excellent in agronomic trait of the improved tobacco, high in yield of high-quality tobacco, high in disease resistance of the improved tobacco and the like.

Description

technical field [0001] The invention belongs to the technical field of tobacco cultivation, and in particular relates to a method for grafting and cultivating tobacco. Background technique [0002] Large-scale planting of a single variety in Yunnan, Guizhou, and Sichuan, the main tobacco producing areas in China, has resulted in weakened tobacco stress resistance, black shank, bacterial wilt, root black rot and other rhizome diseases, underground insect pests, environmental stress damage, etc. The harm is serious, resulting in a reduction in the yield and quality of tobacco leaves, or even a failure to harvest, causing huge economic losses to tobacco farmers, seriously affecting the enthusiasm of tobacco farmers to grow tobacco, hindering the healthy and sustainable development of modern tobacco agriculture, and also bringing adverse effects on tobacco seed breeding . [0003] At present, the methods to reduce the occurrence of diseases and insect pests and enhance tobacco ...
