Sugarcane lodging-resistant strength testing device and using method thereof

Abstract

The invention belongs to the technical field of crop measurement. The invention particularly relates to a sugarcane lodging-resistant strength testing device and a using method thereof. The device comprises a base, a transmission device, a sliding assembly, a pull and push dynamometer and a clamping assembly. The base comprises fixing plates and a connecting plate. Arc-shaped sliding grooves are formed in the fixing plates. Five clamping grooves are formed in the arc-shaped sliding grooves at intervals; 15-degree scale marks, 30-degree scale marks, 45-degree scale marks, 60-degree scale marksand 75-degree scale marks are sequentially arranged below the five clamping grooves in a clockwise direction; the transmission device is fixedly connected between the two fixing plates, one end of thetransmission device is fixedly connected with the bottom of the sliding assembly, the sliding assembly is inserted into the arc-shaped sliding groove and is in sliding connection with the arc-shapedsliding groove, the top of the sliding assembly is fixedly connected with the push-pull force dynamometer through a bolt, and one end of a measuring head of the push-pull force dynamometer is fixedlyconnected with the clamping assembly used for clamping sugarcanes. The device is simple to operate and use and high in test precision, and can test the lodging-resistant strength of the sugarcane by selecting different lodging angles.

Description

technical field [0001] The invention belongs to the technical field of crop measurement, and in particular relates to a sugarcane lodging resistance testing device and a using method thereof. Background technique [0002] Crop lodging refers to the phenomenon that the upright crops are skewed in pieces, and even the whole plant falls to the ground. Lodging can reduce the yield and quality of crops, make it difficult to harvest, and even reduce the yield by more than half in severe cases. Crop lodging mostly occurs in the middle and late stages of crop growth. [0003] In years with severe typhoons and monsoons in our country, lodging sugarcane accounts for about 30%-40%, and in years with light typhoons and monsoons, lodging sugarcane also accounts for 10%-20%, and the yield of sugarcane after lodging is reduced by about 5% %-20%, the sugar content is reduced by about 10%. At the same time, the quality of mechanical harvesting decreased after sugarcane lodging, and the ra...
