How to Achieve High Yield and Efficiency in Rice-Fish Rotation? A Detailed Explanation of the Field-Pond Technique
The field-pond rice-fish rotation is a high-yield, high-efficiency technical model formed in western Fujian over the past two years through continuous improvement based on the extension of "pit-pond" and "ditch-trench" rice-field fish farming. In 2000, Longyan City extended rice-field fish farming over 20,000 mu, of which the field-pond rice-fish rotation area was nearly 5,000 mu. On March 21 this year, the Longyan City Animal Husbandry and Fisheries Bureau and the Liancheng County Science and Technology Bureau organized relevant experts to conduct an on-site sampling inspection of the rice-field fish farming on Li Jincai's household's 1.8 mu of paddy field in Songyang Village, Gechuan Township, where this model was implemented. The total output of fresh fish was 1,112.5 kg

Detailed Introduction to the Rice Variety Fengliangyou No. 2
The female parent M8064S carries a recessive marker gene for bentazon-sensitive lethality. The hybrid combination has a whole growth period of 141 days, strong tillering ability, a plant height of 130.2 cm, 263.6 total grains per panicle, a seed-setting rate of 76.6%, and a 1000-grain weight of 25.6 g. Main advantages: moderate maturity and purity safety. By using a male sterile line combination with a bentazon-sensitive lethal gene marker, when abnormal self-pollination contamination occurs, paddy field herbicides can be applied at the hybrid seed seedling stage to selectively kill self-pollinated seedlings of the male sterile line, ensuring the field production purity of the hybrid rice
