Benefits of technology

This patented technology allows for efficient harvesting of crops such as cereals without damaging their roots. By placing these crops into specific areas along certain lines, they will grow faster because there're fewer root systems needed instead of having them grown throughout. Additionally, this technique helps prevent diseases caused by harmful microorganisms from affecting other parts of the croplants like stems and developing sprouts through natural processes. Overall, this innovator improves efficiency and productivity in agricultural operations.

Problems solved by technology

This technical problem addressed by this patents relates to improving the efficiency with brewing or growing tobaccos like cigarettes without decreasing their quality due to poor germination rates during traditional methods such as burning off harvested crops.

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 ...

example 2

[0057] Example 2, taking 2012, the production demonstration of flue-cured tobacco variety Yunyan 87 artificially assisted pollination carried out at China Tobacco Enshi Fine Breed Breeding Base as an example, the present invention is further described, wherein number A is Yunyan 87 using artificial assisted pollination of tobacco seeds described in the present invention Propagation method, area 17.8 mus, numbering B is Yunyan 87 conventional breeding natural pollination (contrast), area 10.2 mus, its concrete method is with example one, and effect is as follows:

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.
