Example Embodiment

[0040] Example 1:

[0041] A method for interplanting sugarcane and alfalfa includes the following steps:

[0042] Steps for selecting sugarcane seedlings: sugarcane seedlings are selected as new planted sugarcane;

[0043] Steps for planting sugarcane seedlings: plant sugarcane seedlings on the sugarcane in September;

[0044] Steps of interplanting alfalfa: In November, the seeds of alfalfa are sowed on the sugarcane, and the base of the new sugarcane is covered with soil. The sowing rate of alfalfa seeds is 2 seeds per square centimeter.

[0045] Steps for harvesting alfalfa tender stems: After the alfalfa seeds have grown alfalfa tender stems, harvest the alfalfa tender stems when the alfalfa is 15 cm high, and the remaining alfalfa stubble on the ground after harvesting is 2 cm.

Abstract

The invention discloses a sugarcane and alfalfa interplanting method. The sugarcane and alfalfa interplanting method is characterized by comprising the following steps: selecting sugarcane seedlings;selecting to-be-planted sugarcane seedlings; planting the sugarcane seedlings; planting the sugarcane seedlings onto sugarcane ridges; interplanting alfalfa, namely planting the sugarcane seedlings onto the sugarcane ridge, and seeding alfalfa seeds on the sugarcane ridge; harvesting immature stems of the alfalfa, namely harvesting the immature stems of the alfalfa after immature stems of the alfalfa grow out of the alfalfa seeds. According to the sugarcane and alfalfa interplanting method disclosed by the invention, weed growth can be avoided, natural biological fertilizers are provided for growth of the sugarcanes, the soil structure is improved, and the cost is reduced; the land space can be further fully utilized, and good economic benefits are provided for planters.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a method for interplanting sugarcane and alfalfa. Background technique [0002] Sugarcane is an important economic crop in tropical and subtropical regions, and it is also the main raw material for sugar. Generally, the sugarcane that grows from the stem cane buds is called new planting cane, and the sugarcane buds that are left in the ground after harvesting the sugarcane are used to germinate and unearth in a suitable environment, and grow into cane plants, which are called Perennial cane. According to the planting time, the newly planted cane can be divided into: winter planted cane, spring planted cane, summer planted cane and autumn planted cane. Spring planting sugarcane is sugarcane planted from February to April, and harvested in November of that year; autumn planting cane is planted from August to October, and harvested after October of the following year...
