Tobacco-corn no-tillage intercropping compound planting method for increasing maturity degree of tobacco leaves on upper part

Abstract

The invention discloses a tobacco-corn no-tillage intercropping compound planting method for increasing a maturity degree of tobacco leaves on an upper part. The method comprises the following steps: 1) while planting the tobaccos, ridging for planting, wherein the row spacing of the tobaccos is about 50cm, the line spacing is about 120cm, the ridging height is at least 25cm and the ridging width is at least 60cm; 2) selecting the improved seeds of mid-early maturing hybrid corns or fresh corns suitable for the local weather conditions; and 3) before and after collecting the middle leaves of the tobaccos, respectively digging two small holes by using a small shovel in the middle position of two tobaccos on the two sides of a ridging body on a midline of the tobacco ridge, and respectively dibbling two core seeds, wherein the big line spacing of the corns is about 100cm, the small line spacing is about 20cm, the row spacing of the core seeds is as same as the row spacing of the tobaccos, and the strains of the planted corns are 2-4 times of the strains of the tobaccos. According to the method provided by the invention, the problem that the tobacco leaves on the upper part cannot mature in a south tobacco-late rice compound planting area is solved, and meanwhile, the problems of inharmonious labor resources and increased labor cost are also solved.

Description

Technical field: [0001] The invention relates to a tobacco-corn no-tillage intercropping compound planting method for improving the maturity of upper tobacco leaves. Background technique: [0002] In Hunan, Anhui, Hubei, Guangxi and other southern tobacco areas in China, due to sufficient heat and high effective accumulated temperature, the multiple cropping index in agricultural production is relatively high, and tobacco-late rice multiple cropping systems generally exist in tobacco areas for more than one year. In addition to this planting mode of planting another crop after one crop is harvested, intercropping can also be used. As a traditional agricultural planting method in my country, intercropping was described in the "Book of Si Sheng" more than 2,000 years ago. ", and it continues to play a huge role in modern agricultural production. On the one hand, intercropping helps to prolong the growth period of crops and improve their yield and quality. It can also intensive...

Problems solved by technology

[0004] In order to overcome the defects of the prior art, the object of the present invention is to provide a tobacco-corn no-tillage intercropping compound planting method that improves the maturity of the upper tobacco leaves. Its purpose is to overcome the southern tobacco-late rice multiple cropping area. The leaves are not yet mature normally, which causes the problem of decline in the yield and quality of tobacco and subsequent crops. At the same time, it can solve the problem of uncoordinated labor resources and increased labor costs.
