Technical Field

The invention relates to the technical field of agricultural machinery, in particular to an intelligent compound seeder suitable for rice stubble high-humidity land operation.

Background

In recent years, the rainfall capacity is too large in multiple seasons in the middle and lower reaches of the Yangtze river, and the duration of rainfall in certain areas is too long in seasons. According to research, the total rainfall in the middle and lower reaches of Yangtze river is increasing year by year. Objectively result in an increase in the number of wet and rotten plots in the sowing season. However, the existing machine can not sow seeds in wet and rotten plots, and land operation can be performed only when the soil is dried to a certain degree, so that late sowing and late sowing are caused. A large amount of late sowing and late planting means planting and robbing, and the mode of robbing seeds mainly increases the operation speed of machines at present, and the sowing acceleration inevitably leads to the reduction of the sowing quality. Meanwhile, the time of sowing later than the proper sowing period has a great influence on the germination and emergence of seeds, and further the yield is influenced. Therefore, the competition for sowing time is of great significance to farmers. In order to ensure that farmers can normally sow in wet and rotten plots to fight for sowing time, the harm of late sowing is reduced, and the benefits of the farmers are ensured. By combining the currently popularized clean area sowing technology to improve the yield, a sowing machine capable of sowing in the clean area in wet and rotten plots is urgently needed to be researched.
