The Effects of A Novel Rice Establishment Method Combined with Wheat Straw Mulch

Abstract

This experiment compared the effects of a novel rice establishment method with traditional machine-transplanting carpet seedling (MTCS). The new method (RSSR) is a modified direct seeding method, which manually or drone aerial sowed the seeds into the field before wheat harvesting, then cover the seeds with wheat straw after harvesting. Samples were measured to compare the difference of plant height, stem width, and panicle length, straw biomass, effective panicle, spikelets per panicle, panicle weight, 100 grain weight, and grain yield. The results showed that compared with MTCS, RSSR can increase rice growth indicators and yield indicators, but had no significant difference. Only the panicle weight of RSSR was significantly higher than that of MTCS. Furthermore, the management of RSSR was more convenient, which can save water, herbicide and human labor. Thus, this new rice establishment method can be introduced to the wheat-rice and rapeseed-rice rotation area.
