Problems solved by technology

In actual work, it was found that 30%-50% of Yunyan 87 tobacco plants have stamen filaments shorter than pistil stigma, and it is extremely difficult for pollen to fall on the pistil stigma after the anthers mature and split, resulting in more flowers blooming and low fruit setting rate , low seed yield
Therefore, aiming at the problem of low self-fertilization rate in some conventional species of tobacco, it is necessary to invent a method for artificially assisted pollination and reproduction of tobacco seeds, which is very necessary for increasing seed yield and reducing production costs

example 1

[0033] Example 1, taking the artificial assisted pollination production demonstration of the flue-cured tobacco variety Yunyan 87 carried out at the China Tobacco Enshi Fine Breed Breeding Base in 2011 as an example, the present invention is further described, wherein number A is artificial assisted pollination of Yunyan 87, with an area of ​​3 mu, and number B is Yunyan 87 is conventionally propagated and naturally pollinated (control), with an area of ​​12.7 mu. The specific methods and effects are as follows:

[0034] 1. Numbering A Yunyan 87 adopts the method for artificially assisted pollination and reproduction of tobacco seeds of the present invention, and the specific steps are as follows:

[0035] (1) Seedling cultivation: The floating seedling cultivation method is adopted, and the time is in late February. The seedling cultivation technology and seedling management are the same as those of conventional tobacco leaf field production, and are implemented in accordance ...

Abstract

The invention provides a propagation method for tobacco seeds by artificial supplementary pollination. The method specifically comprises the following steps of: seedling; ditching and applying base fertilizers according to a specification that every three rows serve as a tobacco strain belt; covering by a mulching film; transplanting according to a specification that every three rows serve as a tobacco strain belt; uncovering the film and topdressing; intertilling and earthing up; removing impurities and roguing; topping to control height of the tobacco strains in the middle row topped within 100-120cm and height of the tobacco strains in rows on both sides within 90-110cm; picking buds and leaving forks; and applying a fruit bearing fertilizer to promote flower-formation and preserve blossoms; preserving fruits and thinning flowers by artificial supplementary pollination, and collecting matured capsules. The method provided by the invention is simple in operation, low in input production cost and high in seed output. Compared with a conventional method, the propagation method provided by the invention has the advantages that the yield is improved from 5-8kg / mu to 18-27kg / mu, with the increase amplitude which is 3-4 times that of the conventional method.

Description

technical field [0001] The patent of the present invention relates to a method for propagating crop seeds, in particular to a method for artificially assisted pollination and propagation of tobacco seeds. Background technique [0002] Tobacco seeds are the premise and guarantee for the sustainable and stable development of tobacco leaves. At the same time as the production technology of tobacco leaves, the technology of tobacco seed propagation was born. Hubei Province is the main production area of ​​flue-cured tobacco, the largest Burley tobacco production area and the only Maryland tobacco production area. Among them, the annual planting area of ​​flue-cured tobacco is 700,000-900,000 mu, Burley tobacco and Maryland tobacco are 170,000-200,000 mu, and Yunyan 87 is Flue-cured tobacco is the main cultivated variety, and the planting area accounts for more than 70% of the total area of ​​flue-cured tobacco. The varieties used in flue-cured tobacco, Maryland tobacco, and ori...
