Embodiment 1

[0034] Embodiment 1 A kind of method test of improving the success rate of perennial forage corn establishment

[0035] Proceed as follows:

[0036] (1) Sufficient base fertilizer application, ground preparation and compartment: September 20, 2016 at the Chongzhou Modern Agriculture R&D Base of Sichuan Agricultural University, according to 45t / hm 2 Apply the decomposed and nutrient manure evenly on the surface of the planting site, and then plow the soil 20-30cm deep; then make a compartment with a width of 3m, and set up drainage ditches. Set up 6 plots in the planting site, the distance between each plot is 2m, and the plot area is 5m×6m. Set drainage ditches at the boundary of the long axis of the plot, with a depth of 30cm and a width of 35cm. During the planting, the autumn planting and spring planting were randomly designed, and 3 plots were planted each.

[0037] (2) Harvesting of seed stems: On October 1, 2016, at the Chongzhou Modern Agriculture Research and Develo...

Abstract

The invention belongs to the field of breeding methods for perennial forage corn, and specifically discloses a method for improving the success rate of planting perennial forage corn, which mainly involves reducing the number of tillers to 30 to 50 after harvesting in autumn and before turning green in the next year. Plants are dug up, then cut from the base into individual stems, and established. The planting survival rate of the perennial forage corn in the method of the present invention can reach 94%, which is significantly higher than the 80% survival rate of the current spring green plant planting; secondly, the present method is beneficial to seedlings because of the early planting time growth and tillering, and a long growth time, therefore, the annual biological output can reach 94.45t / hm 2 , which is significantly higher than the biological yield of 81.34t / hm by the method of replanting green plants during the Spring Festival 2 In addition, the inventive method has a high survival rate, reduces heavy matters such as transplanting in spring, slowing down seedlings, checking seedlings and replanting, and significantly reduces production costs.

Description

technical field [0001] The invention belongs to the field of asexual propagation methods of perennial forage corn, and in particular relates to a method for improving the success rate of perennial forage corn establishment. 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 has become more serious. ...
