Problems solved by technology

[0002] my country is a big sugarcane planting and sugar producing country, and its annual output ranks third in the world. At present, the area of ​​sugarcane in dry land exceeds 80% of the total planting area, but my country's sugarcane cultivation management and irrigation technology are too backward; impact, sugarcane yield per unit area is far below the world average

Embodiment 1

[0014] (1) Plot selection: On March 4, 2013, the research and development team implemented the method of the present invention in a dry land in Wuming County, Nanning, Guangxi. The area of ​​the plot is about 17 mu, and it is dry all the year round. It is located in a remote place and has no irrigation conditions. Over sugar cane, but the income is very little, and it has been abandoned since then.

[0015] (2) Fenlong: The fertilizer required for the whole growth period of sugarcane before Fenlong is the "Cane Dejin" product fertilizer produced by Guangxi Tianyuan Biochemical Co., Ltd., using 100kg per mu, which will reduce about 70~80% Sprinkle the fertilizer on the ground, and then carry out the powder ridge operation, the depth of the powder ridge is 35~40cm, so that the fertilizer is evenly buried in the cultivation layer, and the sugarcane stems do not use other special treatments, so that the vertical distribution of the sugarcane root system is deep.

Embodiment 2

[0020] (1) Land plot selection: On March 9, 2014, the R&D team continued to implement the technology of the present invention in a dry land in a county in Chongzuo, Guangxi. The land area is about 8.7 mu, which is dry all year round, located in a remote place, and has no irrigation conditions.

[0021] (2) Fenlong: The fertilizer required for the whole growth period of sugarcane before Fenlong is the "Cane Dejin" product fertilizer produced by Guangxi Tianyuan Biochemical Co., Ltd., 70kg per mu, which will reduce about 70~80% Sprinkle the fertilizer on the ground, and then carry out the powder ridge operation, the depth of the powder ridge is 35~40cm, so that the fertilizer is evenly buried in the cultivation layer, and the sugarcane stems do not use other special treatments, so that the vertical distribution of the sugarcane root system is deep.

[0022] (3) Planting and management: Set up small dams every 8 to 12 meters between planting rows (drainage ditches) on flat and dry...

Embodiment 3

[0027] (1) Land plot selection: On March 9, 2014, the research and development team continued to implement the technology of the present invention in the perennial root cane field of Laibin City, Guangxi. Sugarcane was planted after opening up wasteland in 2010. Due to the lack of rainfall, the average sugarcane yield was only 5.6 tons.

[0028] After the sugarcane is harvested in the first year and before new shoots germinate, the researchers make appropriate powder ridges in the furrows and ridges (it is advisable not to damage the roots of the sugarcane), and then set up small dams on the fields or high slopes to store water, collect rainwater, and irrigate. The average yield per mu in the next two years (2015 and 2016) was 7.6 tons.

Abstract

The invention discloses a dry-land smash-riding rain-fed high-efficiency planting method for sugarcanes. The method utilizes smash-riding machinery and a smash-riding tillage technology to perform smash-riding ultra-deep rotary tillage cultivation on sugarcane planting dry land without irrigation conditions; before smash ridging is performed, 70-80% of a fertilizer required in a whole growth period is applied to the ground, then smash-ridging operation is performed, so that the fertilizer is uniformly and deeply buried in a tillage layer, and root systems of the sugarcanes are vertically distributed and deeply buried; and ditching planting is performed in sugarcane planting rows with slopes according to a contour line, one small dam is arranged every about 10 meters among flat ground and dry land planting rows (water discharging ditches) for storing water, when the water is stored to maximization, the water is used to coordinate nutrients, fertilized-fertilizer ingredients and the likein soil while natural rainfall is infiltrated and accumulated to a ''soil reservoir'', in the whole growth period, the nutrients are supplied to the root systems of the sugarcanes in a balanced manner, and the purposes of a high yield and synergy are achieved.

Description

technical field [0001] The invention relates to a method for cultivating crops, in particular to a method for planting sugarcane with high-efficiency rain-fed ridges on dry land. Background technique [0002] my country is a big sugarcane planting and sugar producing country, and its annual output ranks third in the world. At present, the dryland sugarcane area exceeds 80% of the total planting area, but my country's sugarcane cultivation management and irrigation technology are too backward; for the environment that has been arid in recent years As a result, the yield per unit area of ​​sugarcane is far below the world average. For sugarcane without irrigation conditions, how to improve this situation is particularly important. Sugarcane is a crop that needs a lot of water. Water has an important impact on the yield of sugarcane. During the growth period, a certain amount of water is required in the germination, tillering and growth stages. [0003] The inventor, Wei Benhu...
