Fengliangyouxiang No.1 Rice

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

The plant type of this variety is moderate, the plant is neat, the stem is straight, the leaf is wide, the inverted clover is erect, the tillering ability is strong, the fertility is good, the color is good in the later stage, the ear is big and there are many grains, and the seed setting rate is high. The temperature identification point of Hejiashan original seed farm in Hunan province showed that the variety had good resistance to high temperature and cold. The yield of regional test is higher, and the yield stability of high yield is better.

The yield showed in the regional trial in Anhui Province in 2005, the whole growth period was 137.7 days, which was 1.6 days later than that of Shanyou 63 (CK). The yield per mu is 582.04 kg, 8.96% higher than that of Shanyou 63 (CK). In the regional trial in 2006, the whole growth period was 135.7 days, which was 1.6 days later than that of Shanyou 63 (CK). The yield per mu was 591.28 kg, 12.80% higher than that of Shanyou 63 (CK), ranking first in the combination tested. Generally, the yield of field planting is more than 650 kg per mu, and the yield of high-yield field can reach 750 kg per mu.

The key points of cultivation are sowing at the right time, sowing from late April to mid-May in the middle and lower reaches of the Yangtze River, sparsely sowing and evenly sowing, cultivating strong tillers and strong seedlings; the seedling age is about 30 days, and the transplanting specification is 5 inch × 8 inch, with 15000 holes per mu.

Reasonable fertilization, the construction of high-yield seedling frame is based on base fertilizer, timely and appropriate amount of topdressing. Generally, the total amount of nitrogen fertilizer, phosphate fertilizer and potash fertilizer per mu is 14,18kg, 40kg, 50kg and 15kg, respectively. 60% of the total fertilizer amount is used as base fertilizer. After transplanting living trees, 5kg urea per mu was applied to promote tillering.

Moderate water slurry management, enhance the root activity of planting seedlings in shallow water, living trees in an inch of water, tillering in thin water, heading in deep water, dry and wet in the later stage.

The effect of controlling false smut of rice is ideal by spraying 15 ml of 30% Aimiao EC per mu 10 days before heading and at full heading stage. The control measures of rice blast were the same as those of other varieties in the whole period.
