Jinyou 71 (Rice)

Jinyou 71 (Rice)

Variety source: it is a hybrid early rice combination selected by 23A/R71 hybridization used in Chinese rice.

Characteristics: the whole growth period is about 111.0 days, which is about 4.0 days earlier than that of Jinyou 402. The plant height is 88.0 cm, the plant type is compact, the tillering ability is strong, the effective panicle is more, the panicle type is smaller, and the color is good in the later stage. The effective panicle is 259000 per mu. The ear length is 18.9 cm, the total grain number per ear is 94.0 grains, the seed setting rate is 80.4%, and the 1000-grain weight is 25.3 grams. Brown rice rate 81.4%, milled rice rate 72.4%, head rice rate 28.9%, grain length 6.8mm, aspect ratio 3.4, chalky grain rate 83.5%, chalkiness 20.5%, transparency level 3. Gelatinization temperature 4.7, gel consistency 50.0mm, amylose content 18.2%, leaf blast 7, ear blast 9.

Yield performance: the average field yield per mu is 400-450 kg.

Key points of cultivation techniques: sowing seeds at the right time, cultivating strong seedlings; transplanting basic seedlings, planting about 25000 mu of basic seedlings, 100000 mu of basic seedlings; applying sufficient base fertilizer, early heavy application of topdressing to promote early development, applying 25 kg ammonium carbonate per mu and 25 kg calcium superphosphate as base fertilizer. 60% topdressing is required within 7 days after transplanting to make up for the contradiction that Jinyou 71 has a short growth period and insufficient effective panicles, and less nitrogen fertilizer is applied in the later stage. Pay attention to the control of rice blast.
