Abstract:

The effects of wide-narrow row cultivation technique on ratooning rice were studied, using Fengliangyouxiang 1 as material. The results showed that the wide-narrow row cultivation technique increased the ventilation and light transmittance among the rice and reduced the occurrence of sheath blight and rice blast; it was convenient to apply medicine and fertilizer mechanically in the field, and could reduce the mechanical damage to rice; it could reduce the mechanical rolling of rice when harvesting; the wide-narrow row cultivation technique could be fully exerted the marginal effect of rice, and achieved higher yield.

Key words: rice, ratooning rice, wide-narrow row cultivation technique, mechanical rolling
