Introduction to the Fengliangyouxiang No.1 Rice Variety

Fengliangyouxiang No.1 is a new two-line hybrid rice combination with high quality, high yield and aromatic type, bred by Hefei Fengle Seed Co., Ltd. It was approved in Jiangxi Province and Hunan Province in 2006, and approved in Anhui Province in 2007.

Characteristics: This variety has a moderate plant type, uniform plants, upright culms, relatively wide leaves, upright top three leaves, strong tillering ability, good luxuriance, good color retention at the late stage, large panicles with many grains, and a relatively high seed-setting rate. At the temperature identification point of the Hejiashan Original Seed Farm in the Hunan provincial regional trial, this variety showed very good high-temperature resistance and good cold resistance. The yield in the regional trial was relatively high, with good high and stable yield performance.

Yield performance: In the 2005 Anhui provincial regional trial, the whole growth period was 137.7 days, 1.6 days later than Shanyou 63 (CK). The yield per mu was 582.04 kg, an increase of 8.96% over Shanyou 63 (CK). In the 2006 regional trial, the whole growth period was 135.7 days, 1.6 days later than Shanyou 63 (CK). The yield per mu was 591.28 kg, an increase of 12.80% over Shanyou 63 (CK), ranking first among the tested combinations. In field planting, the general yield per mu is above 650 kg, and high-yield fields can reach 750 kg per mu.

Cultivation points: Sow at the appropriate time and transplant at the appropriate time. In the middle and lower reaches of the Yangtze River, sow from late April to mid-May, sow sparsely and evenly, and cultivate strong seedlings with multiple tillers; transplant when the seedling age is about 30 days, with a planting spacing of 5 cun x 8 cun, and 15,000 hills per mu.

Rational fertilization to build a high-yield plant framework: Mainly apply base fertilizer, and topdress at the appropriate time and in appropriate amounts. Generally, apply a total of 14-18 kg of nitrogen fertilizer, 40-50 kg of phosphate fertilizer, and 15 kg of potassium fertilizer per mu; 60% of the total fertilizer application is used as base and surface fertilizer. After transplanting and re-establishing growth, apply 5-8 kg of urea per mu as a topdressing to promote tillering.

Moderate water management to enhance root activity at the late stage: Transplant in shallow water, establish growth with 1 cun of water, tiller with thin water, head with deep water, and keep alternately dry and wet at the late stage.

Pest and disease control: 10 days before heading and at the full heading stage, spray 15 ml of 30% Aimiao emulsifiable concentrate per mu once each time, which gives relatively ideal control of rice false smut. Control rice blast throughout the whole period, and other control measures are the same as those for other varieties.
