Abstract

The invention belongs to the field of propagation methods of perennial forage maize, and specifically discloses a method for propagating perennial forage maize by autumn sowing and spring planting ofstem nodes. According to the method, the stalks of the perennial forage maize are cut into stem segments according to every 3-5 stem nodes in autumn as seedlings, then the stem segments are soaked inwater, and the soaked stem segments are soaked in a disinfection solution for disinfection, and then the seedlings are raised in a propagation nursery, an arch shed is constructed for overwintering, seedling lifting is performed when the temperature rises to 5 DEG C or above in spring, and transplanting is performed. The propagation coefficient of the method can reach 90, which is 5 times higher than that of the traditional division propagation method (18); secondly, the establishment survival rate of the method of the invention is 95%, which is obviously higher than that of the division propagation method (77%); moreover, the annual biological yield of the perennial forage maize planted by the method of the invention is as high as 95 t/hm<2>, which is obviously higher than that of the division propagation method (80 t/hm<2>). The method has the advantages of low cost and provides a guarantee for large-scale planting of the perennial forage maize.

Description

technical field [0001] The invention belongs to the field of multiplication methods of perennial forage corn, and in particular relates to a method for multiplication of perennial forage corn by utilizing stem nodes sown in autumn and planted in spring. Background technique [0002] my country feeds 22% of the world's population with 7% of the world's arable land. With the continuous increase of population and the decrease of arable land, food issues have increasingly become the focus of attention. Especially in the southern provinces and regions of our country, there are many people and little land, and the mountainous area accounts for about 70%, so the food problem is more prominent. The food problem is actually a problem of feed grain to a large extent. With the improvement of people's living standards in our country, the demand for meat and milk food has increased significantly, and the demand for feed grain has further increased accordingly, and the shortage of feed gr...
