Abstract

The invention relates to a method for drought resisting transplanting of flue-cured tobacco through an agriculture and forestry water-retaining agent and belongs to the technical field of cultivation of the flue-cured tobacco. The method for drought resisting transplanting of the flue-cured tobacco through the agriculture and forestry water-retaining agent comprises the four steps of determining the dosage of the agriculture and forestry water-retaining agent for flue-cured tobacco cultivation, selecting soil and the agriculture and forestry water-retaining agent, preparing gel of the agriculture and forestry water-retaining agent, and transplanting flue-cured tobacco seedlings. The method is simple and reliable, and by adopting the method to carry out drought resisting cultivation of the flue-cured tobacco, it can be ensured that the drought resisting time after the flue-cured tobacco is transplanted reaches 20 days or over, the yield per mu can be increased by 9.8-13.3 kg, and the output value per mu can be increased by 327.6-448.2 CNY. Meanwhile, the method relieves white pollution, protects the ecological environment of tobacco fields and is easy to apply and popularize.

Description

technical field [0001] The invention belongs to the technical field of flue-cured tobacco cultivation, and in particular relates to a method for transplanting flue-cured tobacco using an agricultural and forestry water-retaining agent for drought resistance. Background technique [0002] Agricultural and forestry water-retaining agents mostly refer to agricultural superabsorbent resins. Superabsorbent resin is a general term for functional polymer materials with high water absorption characteristics, which can absorb water hundreds of times its own weight. At present, there are generally two categories in the world, namely, starch grafted acrylate copolymer cross-linked product and acrylamide-acrylate copolymer cross-linked product. The water-retaining agent has three characteristics: water absorption, water retention and long-lasting effect. The water absorption of the water-retaining agent includes water absorption capacity, water absorption speed and moisture absorption ...
