Growth period 108.6 days, compared ck Shanyou 64 short 3.0 days. Identification of naturally induced blast resistance: Tony plague 0, 4 leaf blast, neck blast 0. The combination of brown rice rate of 82.8%, 69.9%, milled rice rate, milled rice rate of 57.6%, chalky grain rate of 18.0%, 2.7%, chalkiness, gel consistency 50.0mm, amylose 21.97%, grain length 7.2mm, aspect ratio 3.4.
h 913 excellent cultivation techniques:
The combination of Hunan, Jiangxi night made for precocious cultivation, sowing in late June, moist water seedlings, seedling sowing 15 kg / mu, Honda seed quantity 2 kg / mu 4-4.5 leaf transplanting, seedling age 20-25 day, planting 20,000 acre stump, stump _insert_ed every two Valley. The combination of tillering ability, shorter maturity, should be re Fertilizers, early dressing, Mushi total nitrogen, 10 kg of nitrogen, phosphorus and potassium ratio of 10:6:9, the use of pre-attack, the stability, the control cultivation and management principles to increase the spike head, the focus was to improve the firm. Field timely pest control, scientific management of water |
