Ratoon rice variety identification and selection method suitable for mechanical seed harvesting

Abstract

A ratooning rice variety identification and selection method suitable for mechanical seed harvesting comprises the steps that S10, mechanical seed harvesting is conducted on a plurality of ratooning rice varieties, and detection is conducted to obtain yield indexes and quality indexes of first season rice and ratooning season rice of all the ratooning rice varieties; s20, calculating regeneration production potential of each ratooning rice variety; s30, calculating membership function values of the yield, the brown rice rate, the polished rice rate, the head polished rice rate and the chalkiness of the first season rice and the ratooning season rice of each ratooning rice variety, and calculating membership function values of the regeneration production potential of each ratooning rice variety; s40, calculating a mechanical seed harvesting optimization index of each ratooning rice variety in the target planting field; and S50, sorting the mechanical seed harvesting preferable indexes of the ratooning rice varieties in the target planting land from large to small, and selecting the ratooning rice varieties with the mechanical seed harvesting preferable indexes in the front preset percentage as the ratooning rice varieties of the target planting land. Therefore, the ratooning rice variety suitable for being mechanically planted and harvested in the target planting field is identified and selected.
