Embodiment 1

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

[0042] The step of selecting sugarcane seedlings: sugarcane seedlings are selected as new planting cane;

[0043] The steps of planting sugarcane seedlings: planting sugarcane seedlings on the cane ridge in September;

[0044] Steps for interplanting alfalfa: Sow the seeds of alfalfa on the cane ridge in November, and cover the base of the newly planted cane. The sowing rate of alfalfa seeds is 2 seeds per square centimeter.

[0045] The steps of harvesting the young stems of alfalfa: after the young stems of the alfalfa grow from the alfalfa seeds, harvest the young stems of the alfalfa when the height of the alfalfa is 15 cm. After harvesting, the remaining stubble of the alfalfa on the ground is 2 cm.

Embodiment 2

[0047] A method for interplanting sugarcane and alfalfa, comprising the following steps:

[0048] The step of selecting sugarcane seedlings: sugarcane seedlings are selected as new planting cane;

[0049] The steps of planting sugarcane seedlings: planting sugarcane seedlings on the cane ridge in September;

[0050] The step of interplanting alfalfa: after the step of planting sugarcane seedlings is completed, immediately sow the seeds of alfalfa on the cane ridge, and cover the base of the newly planted cane. The sowing rate of alfalfa seeds is 5 seeds per square centimeter.

[0051] The steps of harvesting the young stems of alfalfa: after the young stems of the alfalfa grow from the alfalfa seeds, harvest the young stems of the alfalfa when the height of the alfalfa is 18 cm. After harvesting, the remaining stubble of the alfalfa on the ground is 2.5 cm.

Embodiment 3

[0053] A method for interplanting sugarcane and alfalfa, comprising the following steps:

[0054] The step of selecting sugarcane seedlings: sugarcane seedlings are selected as new planting cane;

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...
