Increasing generation technique of tobacco

Abstract

The present invention discloses a tobacco Hainan reproduction generation-adding technique capable of implementing two-crop a year system. Said technique includes the following several procedures: (1), selecting soil in Hainan Island, the pH value of said selected soil is about 5.5; (2), promptly sowing the tobacco seeds harvested from inland into the Hainan land; (3), seedling cultivation, gapping and setting plant; (4), making transplantation and applying fertilizer; and (5), making field management. Besides, said invention also provides the concrete steps and requirement of above-mentioned every procedure.

Description

Technical field [0001] The present invention relates to planting technology, in particular, to tobacco planting technology. technical background [0002] my country’s Hainan Province is located in the tropics, with no winter in summer and evergreen in all seasons. It takes full advantage of the tropical resources of Hainan’s “natural greenhouse” to carry out “local breeding and Hainan’s renewal”. This is a way to shorten the breeding period and speed up the pace of breed selection. The effective method has been confirmed by the successful breeding of many crop varieties. The most convincing example is: Yuan Longping, a hybrid rice breeding expert who was one of the winners of my country's Grand Invention Award, found a wild aborted sterile plant (common wild) in the ditch of Nan Fanshi’s farm in November 1970. Rice), wild abortion indica sterile lines (Ejiunan, Erjiu'ai) were bred through cross-breeding, which laid the foundation for hybrid rice research in my country. However, t...
