Cultivation method of late japonica rice Nongjing No.8

Abstract

The invention discloses a cultivation method of late japonica rice Nongjing No.8. The method comprises the following steps of reserving rice seeds of the late japonica rice Nongjing No.8 with large grains through screen crystals for later use, taking a larger vessel, adding 2 / 3 of water into the vessel, adding a proper amount of sodium chloride into the vessel, adding the reserved rice seeds intothe vessel for soaking for 30 minutes, using a stirring rod for slow stirring, and conducting standing and soaking for 10 minutes; taking out the wizened seeds and impurities floating on the water surface, adding a Guangkuling solution with the mass percent of 6% into the vessel for soaking for 2 hours, and filtering out the water in the vessel; then, adding a guangkuling solution with the mass percent of 4% into the vessel for soaking for 14 hours, wherein only the rice seeds and the guangkuling solution remain in the vessel; taking out the soaked seeds for later use. The cultivation method of the late japonica rice Nongjing No.8 achieves the purposes of avoiding a pest damage phenomenon happening to products in the last generation and increasing the germination rate of the seeds and theharvest yield.

Description

technical field [0001] The invention relates to the technical field of rice, in particular to a method for cultivating rice Late Jing Nong Jing 8. Background technique [0002] Rice is a kind of herbaceous Oryza genus, which belongs to cereals, and it is also the most important and oldest kind of food in Oryza genus, which is different from upland rice.
