Description

An in-line double-drive ratooning rice harvester capable of avoiding stubble and its application method

technical field

The invention relates to an in-line double-drive regenerated rice harvester capable of avoiding rice stubble and a using method thereof.

Background technique

Raising rice is a type of rice that has a long history of cultivation in China, dating back to 1,700 years ago. Its characteristic is that after the first season of rice matures, only about 2/3 of the upper part of the rice plant is cut off, and the ears of rice are harvested, leaving the lower 1/3 of the plant and root system, fertilized and cultivated, so that it can grow another season of rice.

When the rice in the first season matures, there will be some axillary buds. After harvesting in the first season, they will be kept. On the basis of the original root system, these axillary buds will grow again and head. After about 2 months, they will mature again and can be harvested. Usually the grains of the rice in the second season are smaller than those in the first season, but the number of rice spikes is more than that in the first season (more than two spikes will usually grow where the original spike of rice is cut), so the yield is low. few. The total of the two seasons is usually 50% higher than the rice yield of the one season, which is of great significance to increasing grain production.

When harvesting rice with a rice harvester, the wheels of the harvester often crush the rice stubble, which affects the production of ratooned rice.
