Abstract

The invention discloses an aeration treating method of tobacco floating seedling. The aeration treating method comprises the following steps of: before seeding and panning, mixing calcium peroxide with matrix according to the using amount of 150.0 to 450.0g / m<3> evenly, adding the calcium peroxide with the concentration of 0.09 to 0.27g / L into pond culture solution when the second true leaf and the sixth true leaf respectively grow out of the tobacco seedling, and other operations are respectively conventional technique. The aeration treating method can solve the hypoxic stress of floating seedling to tobacco seedling, improve the environment for the sprouting of tobacco seeds and growing of the root system of the tobacco seedling, improve the uniformity of seedling emergence, strengthen the activity of the root system of the tobacco seedling, enhance the growth of the tobacco seedling, improve the quality of the tobacco seedling, and is beneficial to culturing disease-free strong tobacco seedlings. The tobacco seedling cultured by adopting the method has the advantages of short seedling emergence time, high transplanting survival rate, strong field growth potential and the like. The invention has simple and convenient operation, low cost and good application prospect.

Description

technical field

[0001] The invention belongs to the technical field of tobacco seedling cultivation, and in particular relates to an aeration treatment method for floating tobacco seedling cultivation. Background technique

[0002] Tobacco floating seedling cultivation is an advanced method of raising seedlings. It has high production efficiency, neat growth of tobacco seedlings, and can effectively avoid the occurrence of soil-borne diseases, insects, and weeds. It has laid a good foundation for cultivating disease-free and strong seedlings, and promoted It has improved the scale, intensification and standardization of tobacco seedling cultivation. The United States, Brazil and other countries are vigorously promoting this new technology. Since our country began to promote the technology of floating seedlings on tobacco in 1996, the technology has developed rapidly. In 2006, the popularization rate of floating seedlings in the country has reached more than 70%. At present...
