Efficient sugar cane cultivation method based on long-acting underground drip irrigation system

Abstract

The invention relates to an efficient sugar cane cultivation method based on a long-acting underground drip irrigation system. A sugar cane underground drip irrigation system arrangement form and a sugar cane wide-narrow row planting mode are provided, the service life of an the underground drip irrigation system is prolonged, labor intensity is remarkably relieved, and labor productivity is improved. A field management water-fertilizer-air-pesticide integrated technique used with the sugar cane underground drip irrigation system is further provided to make full use of the underground drip irrigation full-pipeline system for irrigation, fertilizer and pesticide application and aeration, and accordingly sugar cane yield is effectively increased, early growth and quick tillering of sugar canes are promoted, yield increase and quality improvement are realized, and increasing of yield and incomes of peasant households is promoted. By providing of a capillary pipe arrangement matched underground drip irrigation system filter type selection and combination mode, an irrigation device blockage control method and an underground insect and mouse gnaw damage prevention method, normal and stable operation of the underground drip irrigation system in a sugarcane ratoon crop period is guaranteed, irrigation uniformity of the underground drip irrigation system is improved, and the service life of the underground drip irrigation system is prolonged.

Description

technical field [0001] The invention relates to a sugarcane cultivation method, in particular to a sugarcane high-efficiency cultivation method based on a long-acting underground drip irrigation system. Background technique [0002] Sugarcane is native to tropical and subtropical regions and is widely planted in these regions. The country with the largest sugarcane planting area in the world is Brazil, followed by India, and my country ranks third. Sugarcane is a temperature-loving and light-loving crop, and has a wide range of adaptability to soil, especially clay loam, red loam, and sandy loam. Sugarcane can grow when the soil pH is between 4.5 and 8.0, but the optimum soil pH is between 6.5 and 7.5. Sugarcane is the main sugar crop in my country and occupies an important position in China's agricultural economy. Its output and output value are second only to grain, oilseeds and cotton, ranking fourth. The planting area accounts for more than 85% of the annual sugar crop...

AI Technical Summary

Problems solved by technology

The above patents only propose the water and fertilizer management system during the sugarcane growth period or the soil leveling measures before sowing, but they do not combine the layout of the sugarcane underground drip irrigation system and the management and maintenance of the system in the later stage. The huge potential of the drip irrigation technology has limited effect on promoting the application of drip irrigation technology on sugarcane
