Sugarcane drip irrigation cultivation method based on shallow buried one-time thin-wall drip irrigation tapes

Abstract

The invention relates to a sugarcane drip irrigation cultivation method based on shallow buried one-time thin-wall drip irrigation tapes. The method comprises five parts of mechanized processes including land levelling, fertilizing pipe spreading planting and film covering, field management, sugarcane harvesting and recovery of the drip irrigation tapes; the first part of land levelling includes the following steps: sugarcane field clearing, deep loosening and deep ploughing, smashed-soil levelling, and pre-furrowing of rows; the second part of fertilizing pipe spreading planting and film covering includes the following steps: base fertilizer applying, drip irrigation tape spreading, sugarcane planting, earthing compaction and mulch film covering; the third part of field management includes the following steps: intertillage fertilizing and soil cultivating, mechanical spraying of a post-emergence herbicide, mechanical weeding and mechanical spraying for preventing and controlling pestsand diseases according to different harvesting areas; the fourth part of sugarcane harvesting is divided into cut-off joint harvesting work, whole-pole-type combined harvesting work and segmented step-by-step harvesting work; and the fifth part is recovery of the drip irrigation tapes. The method provided by the invention combines a one-time surface shallow-buried drip irrigation technology witha whole mechanization technology of sugarcane planting to establish the modernization planting means and management measures of sugarcanes.

Description

technical field [0001] The invention relates to a cultivation technique for sugarcane, in particular to a drip irrigation cultivation method for sugarcane based on shallow burial of disposable thin-walled drip irrigation belts. Background technique [0002] As one of the main raw materials of my country's sugar industry, sugarcane not only has a significant impact on the national economy, but is also closely related to the national sugar supply security. my country's sucrose production areas are mainly distributed in southern regions such as Guangdong, Taiwan, Guangxi, Fujian, Yunnan, Sichuan, Guizhou and Hainan. In the early 1980s, Guangdong was the largest sugar cane producing area in my country, and its area and output accounted for 37% and 42% of the national sugar cane area and output respectively. and only account for 34% and 25% of the national sugar cane area and output. Since the 1990s, with the rising cost of labor and land in the eastern coastal areas, sugar cane...

Problems solved by technology

[0005] At present, many experts and scholars have proposed sugarcane planting and cultivation methods, such as: Dayu Water Saving (Tianjin) Co., Ltd. (Patent No.: CN201510880894.2) proposed a Guangxi sugarcane underground drip irrigation water and fertilizer integrated planting method, including seed selection and seeds Treatment, site selection and preparation, seeding, drip irrigation belt laying, field management and integration of water and fertilizer require the sowing depth to be 30cm below the surface, and the drip irrigation belt laying depth to be 0.15-0.30m, but it does not solve the annual cost of drip irrigation belts buried underground. The problem of manual management and maintenance, the laying method of the drip irrigation belt and the mechanized supporting measures in the planting process are not introduced
