A upland rice variety with stable yield of 1000 jin-Taixuan No. 1

Upland rice Taixuan No. 1 is a new upland rice strain carefully selected from Thailand Desert No. 3 upland rice by Huang Huaihai Upland Rice Research Center of Ministry of Agriculture and Shandong Jinan Huinong seed Industry Co., Ltd. Through the test and demonstration in the demonstration bases of Jiangsu, Shandong, Henan and Anhui provinces, it is proved that the yield per mu is up to 500 kg ~ 600 kg, and the highest yield per mu can reach more than 700 kg.

Characteristic characteristic

The whole growth period of Taixuan No. 1 is 100 ~ 120 days, with sturdy stem, strong tillering ability, developed root system, fast filling speed, disease resistance and barren resistance, drought and waterlogging resistance, large ear and grain, high and stable yield. After three years of comparative test and demonstration, the yield can be increased by about 30% and 50% compared with the general upland rice varieties currently popularized in China (such as Beijing 277, Beijing 297 and Brazilian upland rice). Under the condition of dry weather in 1999, 30 mu of Taixuan No. 1 upland rice planted by Huang-Huai-Hai Upland Rice Research Center had an average yield of 597 kg per mu under the condition of only one watering, while that of the other five varieties was only about 300 kg ~ 350 kg per mu. In 2000, 200 mu were planted in Jiyang, Shandong Province. the average yield per mu was 531.8 kg and the highest yield per mu was 704.5 kg.

The rice grain is oval, which belongs to waxy japonica rice, and its quality is comparable to that of high-quality japonica rice.

Sowing time and method

For planting wheat stubble in the Yellow River basin and parts of North China, it is better to sow before June 15, and spring sowing can be arranged in mid-late April. Early seedling transplanting or direct seeding can be used for sowing. The seed amount per mu is 7.5 kg.
