Dannuo No. 2 rice

Dannuo No. 2 rice is a new glutinous rice line bred systematically for many years by using Fan 4 as female parent and Liaoyan Nuo 4 as male parent in 1998, which was systematically selected by Dandong Academy of Agricultural Sciences. It was approved and named by Liaoning Variety approval Committee in 2001. Characteristics: the seedling has developed root system, strong tillering ability, plant height of 100 cm, 16 leaves of the main stem, elegant leaves, lifting up. The plant belongs to the compact type, the stem is stout, lodging-resistant, the living stem is mature, the ear length is 15 cm-16 cm, the ear is erect, 100-110 grains per ear, the seed setting rate is 85%, the 1000-grain weight is 25 grams, and there is no awn. The growth period is 162 days, which is a late-maturing variety. Key points of cultivation: sow seeds at the right time and cultivate strong seedlings. It is appropriate to sow seeds in Dandong and Dalian in mid-April, with about 200 grams per square meter of ordinary seedlings and 60 grams-70 grams per plate of plastic diskette seedlings and manual transplanting seedlings. In order to cultivate tillers and strong seedlings, milk fertilizer was applied in one leaf and one heart. Transplanting in time, reasonable and sparse planting. The seedling can be transplanted when the seedling age is 35-40 days, and the row spacing is 33 cm × 14 cm or 30 cm × 18 cm. Manage water scientifically and fertilize reasonably. The pipe water method with the combination of shallow, wet and dry is adopted, mainly shallow, which can be drained to dry or roast the field at the early jointing stage. generally, ammonium sulfate and diammonium phosphate are applied 45 kg per mu and 7.5 kg per mu in fertile plots, phosphate fertilizer is applied once and for 5 times in three stages, so as not to cause greedy green late maturity and the occurrence of diseases and insect pests. Control diseases and insect pests and ensure a bumper harvest. This variety is resistant to rice sheath blight, bacterial blight, rice blast and medium resistance to rice false smut. The mixture of tricyclazole and Jinggangmycin was sprayed once at tillering stage and breaking stage respectively in the area with recurrent rice blast. Ye Qingshuang should be used to strengthen the control of bacterial blight in the land with severe bacterial blight. Rice Fengling can be used to control rice false smut. In addition, the control of Chilo suppressalis, rice water weevil and rice leaf roller should be strengthened. Suitable areas: suitable for planting in southern Liaoning, central Hebei, northern Shanxi, western Shaanxi and central Shaanxi, as well as Zhongdan 2, Jingyue 1 and Danjing 4.
