Embodiment 1

[0036] Example 1 Contrast experiment of perennial forage corn stem section of the present invention sown in autumn and planted in spring

[0037] Proceed as follows:

[0038] (1) On September 15, 2016, the ground preparation and opening of the multiplication garden: In the Chongzhou Modern Agriculture Research and Development Base of Sichuan Agricultural University, a plot with loose, fertile and sunny soil was selected as the multiplication garden, and the multiplication garden was plowed and harrowed until the soil loosened , flat; and 1.5m wide as the compartment, the distance between the two compartments is 50cm.

[0039] (2) Stalk harvesting and seed production on September 20, 2016: At the Chongzhou Modern Agriculture Research and Development Base of Sichuan Agricultural University, the Yucao No. After being approved by the Sichuan Provincial Grass Variety Approval Committee, 10 individual plants can be randomly marked in the Sichuan Agricultural University) to investig...

Abstract

The invention belongs to the field of breeding methods of perennial forage corn, and specifically discloses a method for multiplying perennial forage corn by using stem nodes to sow in autumn and plant in spring; the method uses 3 to 5 stem nodes to grow perennial forage corn in autumn The stalks were cut into stems as seedlings, and then soaked in water and disinfected with disinfectant; they were then placed in a multiplication nursery for seedling cultivation, and arch sheds were built for overwintering. Seedlings were raised when the temperature rose above 5°C in spring, and transplanted planted. The reproduction coefficient of the method of the present invention can reach 90, which is 5 times higher than the reproduction coefficient of the traditional ramet propagation method of 18; secondly, the survival rate of planting in the method of the present invention is 95%, which is obviously higher than the 77% survival rate of the ramet propagation method ; In addition, the annual biological yield of the perennial forage corn planted by the inventive method is up to 95t / hm 22 , significantly higher than the 80t / hm of ramet propagation method 2 The cost of the method of the invention is low, which provides a guarantee for the large-scale planting of perennial forage corn.

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 using 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 grain ...
