A New glutinous Rice Variety Dannuo 2
Characteristics: plant height 105 cm, leaf short impulse, compact plant type, stout stem, upright lodging resistance. Ear length 16 cm, tight panicle type. 90 grains per panicle, 1000-grain weight 26.5 grams, awnless. Relatively resistant to rice blast, medium resistance to sheath blight, bacterial blight and rice false smut. The general yield of Dannuo 2 is between 50000kg and 550kg. Under the same cultivation mode, the yield is the same or slightly increased as that of other non-sticky rice varieties, and has a good yield stability. Dannuo No. 2 is a sticky rice variety with a purity of 99.6% and high viscosity.
Main points of cultivation: sowing from April 20 to 25, transplanting seedlings at the end of May and the beginning of June, the transplanting density is 30 × 14 cm, and 5 seedlings per hole. This variety is suitable for throwing seedlings, and the seedling throwing density is 25 holes per square meter. It needs 45 kg of ammonium sulfate, 10 kg of diammonium and 7 kg of potash fertilizer per mu. Excessive post-fattening is easy to induce false smut of rice. Soaking seed Ling (6 kg dry seed / branch) for 4-5 days can effectively prevent dry tip nematode and evil seedling disease, and 0.25 kg 18% insecticidal double water agent per mu can be used to prevent pests such as Chilo suppressalis.
