Examination and approval of Sichuan rice 2004001

This variety is the new combination with the highest yield of middle rice approved in Sichuan in 2004. the growth period is 155days, which is about 3 days longer than Shanyou 63, effective panicle 179300 / mu, plant height 115.3 cm, panicle length 24.2cm, 157.6 grains per panicle, seed setting rate 85.8%. 1000-grain weight 26.6g. The combination has good leaf type, hard stem, large panicle and many grains, high yield, strong stress resistance, good comprehensive disease resistance and wide adaptability, and no rice blast and bacterial blight occurred in the field. After the determination of rice quality, its taste and comprehensive quality reached the upper-middle level.

The yield showed that the average yield per mu in the provincial regional trial in 2003 was 571.2 kg, which was 8.78% higher than that of the control Shanyou 63, and the difference was extremely significant, ranking first in the experiment. The yield was increased at all 14 points (2 points significant, 10:00 very significant). In 2002, he participated in the regional trial of medium-late high-yield group of rice in Sichuan Province, ranking first, with an average yield of 565.76 kg per mu, which was 7.96% higher than that of Shanyou 63. The average yield per mu in two years was 568.93 kg, an increase of 8.22% over the control, ranking first. The average daily output in two years is 3.67 kg, which is 0.19 kg higher than that of the control. In the production test in 2003, the average yield per mu at five points was 645.4 kg, which was 17.84% higher than that of Shanyou 63. In 2003, we participated in the regional trial of Guangxi early rice group, with an average yield of 528.3 kg per mu, ranking second among the tested varieties. The production experiment was carried out in Zhouqiao Village Nine Society, East Township, Xuanhan County, Sichuan Province in 2003. the yield per mu reached 629kg, which was 15.2% higher than that of Shanyou 63, and the yield per mu was 811.43 kg in Lijia Town, Shunqing District, Nanchong. It is suitable for the introduction, trial and extension of one-cropping middle rice and double-cropping rice of Shanyou 63.

Cultivation points timely early sowing, reasonable close planting, seed amount 1.25kg per mu, planting 1.5-2.2 million holes per mu, applying sufficient base fertilizer, paying attention to the proper application of panicle fertilizer at jointing stage, higher yield can be obtained.
