High yield of water in rice during waxy maturity

Rice is reasonably used for water during the filling and filling period, which can raise roots and keep leaves, ensure smooth filling and increase the 1000-grain weight of the seeds. If the rice is insufficient in the late growth stage, the leaves will be yellowed early, resulting in reduced yield. Scientific research has confirmed that after the rice grows to the wax ripening stage, about 30% of the material needs to be synthesized and transferred into the seed. Therefore, in the late stage of rice filling, it is still necessary to ensure sufficient water supply, and the soil water content can be 90% of the maximum water holding capacity of the field soil.

In order to root and protect the leaves, intermittent irrigation can be used in the late growth stage of rice, that is, once water is poured, re-irrigated after re-drying, and the time of water accumulation in rice fields is gradually reduced as the rice matures. The last water cut before harvesting should be based on the specific conditions. Flexible to master. When the rice matures, the temperature is higher, the water transpiration is faster, or the terrain is higher, the irrigation and drainage is convenient, and the water cut can be appropriate later. Generally, the water can be cut off 3 to 5 days before harvesting; if the rice is mature, the temperature is low, and the soil is sticky. Heavy, water cut can be appropriate earlier, generally 10 to 15 days before harvesting water is appropriate.
