Method for mechanically planting and harvesting cassava

Abstract

The invention discloses a method for mechanically planting and harvesting cassava. The method is characterized by comprising the following steps: A, performing ditching and performing ridging: performing rotary tillage soil crushing and levelling on cultivated land by utilizing a rotary tillage ridging machine, performing ditching and ridging by utilizing a rotary tillage ridging machine, and after a ridge is formed, forming furrows used for walking of tractor wheels on two sides of the ridge; B, performing planting: planting two rows of cassava plants in the ridge surface along a longitudinaldirection by utilizing a real-time cutting-type double-row cassava planting machine pulled by a tractor; C, performing field management; D, smashing stalks; and E, performing harvesting: after the cassava stalks are treated, performing harvesting by utilizing a cassava excavation harvester pulled by a tractor. The method provided by the invention completes cassava planting through the manners oflarge-ridge forming, double-row planting on the ridge, different widths of line spacing of the cassava on the ridges and among the ridges, management in the whole process can realize mechanized operation, the production efficiency of the cassava is greatly improved, input of manpower is greatly reduced, a loss rate and a cassava damage rate can be reduced, and high-efficiency low-cost harvesting is realized.

Description

technical field [0001] The invention relates to the field of cassava planting, in particular to a method for planting and harvesting cassava. Background technique [0002] Cassava is one of the three largest potato crops in the world. It is the food that more than 600 million people in the world depend on for survival. It is also an important starch raw material crop and biomass energy crop. Cassava is mainly used as a starch raw material crop in my country. According to FAO data, in 2016, the harvested area of ​​cassava in my country was 291,100 hectares, and the output was 4.7943 million tons. In 2017, my country's cassava harvested area was about 247,400 hectares, and the output was about 4.0752 million tons. [0003] Traditional cassava planting is mainly manual, with low efficiency, poor standardization and regulation of planting, and cannot meet the requirements of large-scale and mechanized production. With the sharp increase of agricultural labor costs and the red...

AI Technical Summary

Problems solved by technology

Cassava mechanized planting and harvesting operations have begun in southern my country, Southeast Asia, Africa and other regions, but at present, due to the diversity of cassava planting agronomy, the agronomic model cannot meet the requirements of implementing mechanized operations

[0004] The artificial planting of cassava is mainly planted with equal row spacing. The deviation of row spacing is large, the row straightness is poor, and the ridge shape is low. The following problems exist in the implementation of mechanized operations: 1. Planting row spacing and tractor wheelbase and planting machinery, management machinery, and harvesting machinery The tires of tractors and agricultural implements are not pressed in the furrows but on the cassava ridges during mechanized operations, which may damage cassava plants or crush cassava roots; The planting row spacing does not match, it is impossible to excavate the rows, and it is difficult to control the direction and depth of the excavation, resulting in cassava roots being easily shoveled by the harvester, and the harvest loss rate is high; Large, high energy consumption, accelerated tool wear
