| Abstract: | The growth period of Nei2You 6 is 146 days, used as single-rice in Zhejiang. It is characterized by moderate tillering capacity, large panicle of 200 grains per panicle, large grain weight of 30.5g per 1000 grain, strong lodging resistance, and wider and large leaf. Main practice of cultivation technology for high yield is to raise healthy seeding with more tillers, sparsely transplant with the wider space , controll application amount of nitrogen fertilizer at the middle and late stage and increase application amount of potassium, practice the alternative irrigation of wetting and dry to promote the root growth and vigor, and spikelet fertility. |
