Abstract

The invention belongs to the technical field of forage grass cultivation, and provides a wide-narrow-row one-hole double-plant on-film soil covering cultivation method for sorghum sudanense. The method comprises the following steps: performing film covering after sorghum sudanense seeds are sown, and covering a film with soil after film covering is completed: taking the sorghum sudanense seeds asthe center, and covering the covering film with a 2-3cm soil layer within 10 cm radius. By means of the technical scheme, the yield and benefits are guaranteed, and meanwhile the problems that in theprior art, after sorghum sudanense is sown for one month, due to drought weather, little rain and much wind and large earth surface evaporation, soil moisture of a plough layer is seriously lost, seedlings are difficult to protect after sowing, and the emergence rate is low are solved.

Description

technical field [0001] The invention belongs to the technical field of forage grass cultivation, and relates to a method for cultivating sorghum grass with wide and narrow rows and one hole with two plants covered with soil on film. Background technique [0002] Sorghum bicolor×Sorghum sudanense is a distant hybrid of sorghum (Sorghum bicolor (L.) Moench) and Sudan grass (Sorghum sudanense (Piper) Stapf.), an annual warm-season forage grass belonging to Poaceae. High-efficiency C4 crops have the characteristics of strong hybridization, strong stress resistance, high biological yield, excellent feed quality, and multi-crop utilization. They can make full use of light, temperature, rain, and heat resources for growth. Farmers' favor. However, in the Haihe Plain area, as a typical growing area of ​​Sorbus dansana, the sowing time is generally in mid-April every year, waiting for rain or creating moisture, and the planting method is row planting with equal row spacing in the op...
