Pea and tobacco intercropping method

Abstract

The invention discloses a pea and tobacco intercropping method. According to the method, based on the technical background of tobacco monoculture in the southwestern tobacco-growing area, pea seeds are sown on two sides of a tobacco ridge after laminas on the lower middle portion of tobacco are harvested or after harvest is completed, and a plastic net is hung on a tobacco stem as the climbing support of a pea, and then pea and tobacco intercropping is achieved. The pea and tobacco intercropping method has the advantages that the multiple crop index of land is improved; fertilization is not needed for pea planting, a large quantity of nitrogenous fertilizer and potash fertilizer left in tobacco land can be utilized, and the economical benefit of tobacco farmers is increased by 1000-1200 yuan / mu; the tobacco stem is used as the climbing carrier of the pea, and cost of 200-400 yuan / mu for building a support for the pea is saved; and due to the fact that the height of the tobacco stem can not meet climbing requirements of the pea, the plastic net is laid on the top of the tobacco stem by the applier to enable the pea to continue to climb after reaching to the top of the tobacco stem, and technical prejudice of technicians in the field is overcome.

Description

technical field [0001] The invention relates to an intercropping method of peas and flue-cured tobacco, in particular to a cultivation technique for interplanting peas during the growth period of flue-cured tobacco. Background technique [0002] Most of the tobacco areas in Southwest China adopt flue-cured tobacco monoculture, the crop multiple cropping index is low, and light resources are wasted seriously; and flue-cured tobacco requires sufficient soil fertility when planting flue-cured tobacco, so there is still a large amount of nitrogen and potassium fertilizers in the soil that have not been absorbed after flue-cured tobacco is harvested There is a lot of rain in the southwest region in autumn, and the fertilizer in the soil is easy to lose, and the waste of fertilizer efficiency is serious. Simultaneously flue-cured tobacco is harvested completely, and the cleaning of tobacco rod is time-consuming and labor-intensive, pollutes the environment after burning. However,...

Problems solved by technology

[0002] Most of the tobacco areas in Southwest China adopt flue-cured tobacco monoculture, the crop multiple cropping index is low, and light resources are wasted seriously; and flue-cured tobacco requires sufficient soil fertility when planting flue-cured tobacco, so there is still a large amount of nitrogen and potassium fertilizers in the soil that have not been absorbed after flue-cured tobacco is harvested There is a lot of rain in the southwestern region in autumn, and the fertilizer in the soil is easy to lose, and the waste of fertilizer efficiency is serious

At the same time, after the flue-cured tobacco is harvested, the cleaning of the tobacco rods is time-consuming and labor-intensive, and it pollutes the environment after burning

However, the height of the climbing bracket as a climbing plant is generally required to be 1.5-2m, and the height of the tobacco rod cannot meet the requirements and cannot be used effectively.
