Description

A corn seedling lodging resistance test device

Technical Field

The invention relates to the field of lodging resistance test, in particular to a corn seedling lodging resistance test device.

Background technique

Corn is an annual monoecious cross-pollinating plant with tall plants and strong stems. It is an important food crop and feed crop, and is also the crop with the highest total output in the world. Its planting area and total output are second only to rice and wheat. Corn has always been praised as a longevity food. It is rich in protein, fat, vitamins, trace elements, cellulose, etc., and has great potential for the development of high-nutrition and high-biological functional foods.

Among them, the lodging resistance of corn seedlings has always been a major indicator of corn quality. Lodging can reduce the yield and quality of corn and make harvesting difficult. Therefore, the lodging resistance test of corn seedlings is particularly important. However, the existing publication number is CN214310419U, and the name is a corn seedling lodging resistance test device, which includes a test box, a spray pipe and a fan.

2. During the test, the threaded column can be loosened to allow the inserted column that is tightly fixed by the threaded column to move, and then the inserted column is knocked into the soil layer to reinforce the carrier to ensure that the carrier will not be displaced by the reaction force of the wind during the test, thereby ensuring the stability during the test.

3. When the carrier is stopped in an uneven test field outdoors for testing, the threaded sleeve can be rotated so that the threaded sleeve can move with the threaded rod to adjust the distance between the two limit seats, and then the distance between the upper seat and the lower seat can be adjusted through the adjustment frame.
