Problems solved by technology

In addition, the nursery period is the critical period for the nutrient absorption of tobacco seedlings. Too much fertilizer may reduce the stress resistance of transplanted tobacco plants, and too little fertilizer will affect the growth of tobacco seedlings and fail to obtain strong seedlings.
However, in the current water and fertilizer management methods carried out in accordance with relevant standards, the amount of water and fertilizer is relatively large, which can meet the requirements of strong tobacco seedlings and field transplanting. Risk of polluting the land environment

Abstract

The invention relates to a conventional water-saving and fertilizer-saving tobacco seedling raising method. The method comprises the steps of substrate dishing, sowing, management from sowing to seedling emergence stage, management from seedling emergence to seedling formation stage and the like. Compared with a flue-cured tobacco seedling raising technical procedure, the water-saving and fertilizer-saving seedling raising method has the advantages that the water and fertilizer input amount is obviously reduced; the water consumption in the whole seedling culture period is reduced; after seedling culture is completed, the residual quantity of nutrients such as nitrogen, phosphorus and potassium is obviously reduced; and meanwhile, the nitrogen-phosphorus-potassium nutrient absorption amounts of tobacco seedlings in the whole growth period are increased to different degrees.

Description

【Technical field】 [0001] The invention belongs to the technical field of tobacco production. More specifically, the present invention relates to a water-saving and fat-saving seedling raising method for conventional tobacco seedlings. 【Background technique】 [0002] Seedling raising is an important part of tobacco production. Seedling raising and transplanting have the advantages of shortening the growth period of the field, increasing the multiple cropping index, and artificially providing suitable light, temperature, water and fertilizer conditions. The Speeding Company of the United States developed the floating seedling raising technology in 1986, and then it was rapidly promoted in the United States, Canada, Brazil and other tobacco developed countries. my country introduced floating seedling raising technology in 1994 and began to promote and apply it to the whole country. Up to now, 97.02% of the total area of ​​tobacco seedlings in my country is raised by floating ...
