Embodiment 1

[0045] Example 1: Multi-season light and simple cultivation method of sugarcane perennial root in dry land

[0046] Sugarcane variety: Yuetang No. 60

[0047] The newly planted sugarcane cultivation method adopts the conventional method. The planting time of the newly planted sugarcane is selected from February to March, the soil is deeply loosened, the cane ditch is 30cm to 35cm, the bottom width of the ditch is 19cm to 21cm, and the row spacing is 0.9m to 1.2m; the buds per mu are 7000 Buds ~ 8000 buds, apply long-acting compound fertilizer for sugarcane after budding, 130 kg / mu per mu; special compound fertilizer is self-mixed, N:P in compound fertilizer 2 o 5 :K 2 O nutrient distribution ratio is: 23:8:15; application rate is 130kg / mu; low-toxicity and high-efficiency granule pesticide chlorpyrifos content is 5%, and application rate is 10kg / mu. Until the sugarcane is harvested, the newly planted sugarcane will be harvested and cut in December of that year. After the ...

Embodiment 2

[0083] Example 2: Multi-season light and simple cultivation method of sugarcane perennial root in dry land

[0084] The difference between this embodiment and embodiment 1 is:

[0085] When the perennial sugarcane is cultivated in the first season, the second step: after shoveling and drying the top soil until the surface soil is blanched, then fertilize, apply long-acting compound fertilizers and insecticides for sugarcane, and use N:P in the special long-acting compound fertilizers 2 o 5 :K 2 O nutrient distribution ratio is 25:12:18, and consumption is 120kg / mu; Insecticide selects low toxicity and high-efficiency granular pesticide monochlorpyrifos for use, content is 5%, and insecticide consumption is 8kg / mu, prevents and controls underground pest; After mixing the effective fertilizer and pesticide, apply it in the sugarcane ditch with a shallow cover of 5cm to 7cm. After that, the sugarcane field will be ridged with pine ridges, and the height of the ridge will be 2...

Embodiment 3

[0094] Example 3: Multi-season light and simple cultivation method of sugarcane perennial root in dry land

[0095] The difference between this embodiment and embodiment 1 is:

[0096] When the perennial sugarcane is cultivated in the first season, the second step: after shoveling and drying the top soil until the surface soil is blanched, then fertilize, apply long-acting compound fertilizers and insecticides for sugarcane, and use N:P in the special long-acting compound fertilizers 2 o 5 :K 2 The O nutrient distribution ratio is 22:10:16, and the dosage is 150kg / mu; the insecticide is selected from low-toxicity and high-efficiency granular pesticide killing monochlorpyrifos, the content is 5%, and the dosage of insecticide is 10kg / mu to prevent and control underground pests; After mixing the effective fertilizer and pesticide, apply it in the sugarcane ditch with a shallow cover of 5cm to 7cm. After that, the sugarcane field will be ridged with pine ridges, and the heigh...

Abstract

The invention belongs to the technical field of agricultural cultivation, and particularly relates to a dryland sugarcane perennial root multi-season simple cultivation method. The method comprises the following steps of (1) first season cultivation of the sugarcane perennial root, wherein newly-planted sugarcane is harvested and cut, the sugarcane field is cleaned, stumps are eradicated in time, long-acting compound fertilizer and pesticides are applied, the stumps are loosened and ridges are raised, and the whole field with suitable moisture in soil is covered with weeding biodegradable mulching film; (2) second season to N season cultivation of the sugarcane perennial root, wherein the sugarcane of last season is cut and harvested, then the whole field is covered with sugarcane leaves, modified molasses alcohol residual liquid is sprayed, and pests are controlled timely in the growth process of the sugarcane until the harvest. The cultivation method of 'whole field weeding biodegradable mulching film covering and the long-acting fertilizer' in the first season perennial root, and of 'whole field sugarcane leaf covering and the modified molasses alcohol residual liquid' in the second season to N season perennial root has the advantages of being fertilizer-saving, labor-saving and obvious in yield increasing effect, and solving the problems that the number of times of fertilizer application is many, the pests and weeds control is difficult, management labor-consuming is much and the like.

Description

technical field [0001] The invention belongs to the technical field of agricultural cultivation, and in particular relates to a multi-season light and simple cultivation method for sugarcane perennial roots in dry land. Background technique [0002] Sugarcane is an important sugar crop in my country, and sugarcane sugar accounts for more than 90% of the country's total sucrose production. At present, from the perspective of sugar production costs in my country, the cost of raw sugar cane accounts for 70% of the entire sugar production cost. Therefore, the key to improving the competitiveness of my country's sugar cane and its sugar processing industry is to reduce the cost of raw sugar cane. [0003] Sugarcane is a perennial root crop. With proper management, a new plant can last for 3 to 7 years. Due to poor soil conditions and backward management techniques in sugarcane areas in my country, the lifespan of sugarcane perennials is generally only 2 to 3 years. Planting suga...
