Last Updated: 2024/11/22, The average yield per hectare in the regional trial from 1998 to 1999 was 7415.3 kg, which was 18.0% higher than that of the control variety Heijing 5, and the average hectare yield in the production trial in 2000 was 6869.0 kg, which was 14.2% higher than that of the control variety Heijing 5. Characteristic japonica rice, the number of growth days is about 126 days, and the active accumulated temperature is 2393 ℃. The plant height is 86.5 cm, the ear length is 16.1 cm, the number of grains per ear is about 95, and the 1000-grain weight is 28.1 g.

Characteristic japonica rice, the number of growth days is about 126 days, and the active accumulated temperature is 2393 ℃. The plant height is 86.5 cm, the ear length is 16.1 cm, the number of grains per panicle is about 95, and the 1000-grain weight is 28.1 g. From 1999 to 2000, the seedlings were artificially inoculated with 5mure 6, leaf blast 5, ear neck blast 9, naturally susceptible seedling blast 3-6, leaf blast 3-5, ear neck blast 7. Brown rice rate 82.9%, milled rice rate 74.6%, head rice rate 71.7%, ratio of length to width 1.7, chalkiness size 10.8%, chalky rice rate 8%, chalkiness 0.8%, alkali elimination value 7, gel consistency 59.3 mm, amylose content 18.31%, crude protein content 7.93%.

The key points of cultivation are dry cultivation and sparse planting cultivation, with transplanting specifications of 30 × 10-12 cm and 3-4 plants per hole. It is best to plant in a pot to promote tillers and protect the number of ears. It has strong fertility tolerance and is suitable for cultivation under medium fertility conditions. In the years of leaf sheath rot and brown spot, attention should be paid to disease prevention, using 5 kg carbendazim, 1.5 kg rice vinegar, 1.0 kg potassium dihydrogen phosphate and 150 kg water spray per hectare to prevent browning.

It is suitable for transplanting seedlings in the fourth accumulated temperate zone in Heilongjiang Province.
