High-yield cultivation techniques for no-till direct seeding in rapeseed-rice double cropping
Zhejiang Province is relatively economically developed, with high labor costs. At the same time, as diesel prices rise, the cost of mechanical plowing of farmland increases, and the production cost of grain and oil crops increases year by year. For this reason, Zhejiang Province carried out trials, demonstrations and extension of high-yield cultivation techniques for no-till direct seeding in rapeseed-rice double cropping, which reduced the production cost of grain and oil crops and improved planting efficiency. According to surveys, each mu of no-till direct-seeded rapeseed saves 62.5 yuan in costs and increases efficiency compared with transplanted rapeseed, and each mu of no-till direct-seeded late rice saves 70.24 yuan in costs and increases efficiency compared with plowed and transplanted late rice. The annual cumulative cost saving and efficiency increase of no-till direct seeding cultivation in rapeseed-rice double cropping is 132.74 yuan.

Key Points of High-Yield Cultivation Techniques for the Japonica Hybrid Rice Liuyou No. 1
Through analysis of the field growth and yield structure of Liuyou No. 1, its main technical measures are considered to be: (1) Fully adopt the two-stage seedling method of dry raising and water transplanting. Apply fertilizer scientifically, strictly manage water and slurry, master shallow-water frequent irrigation, and use soft-board transplanting in the seedling-nursing field. (2) Appropriately widen the plant and row spacing at transplanting, use single-plant transplanting throughout, and increase the proportion of productive tillers from low nodes in the main field. (3) On the basis of applying sufficient basal fertilizer, heavily apply panicle fertilizer to promote large panicles, skillfully apply grain fertilizer to increase the seed-setting rate and thousand-grain weight. Apply paclobutrazol in a timely manner to prevent lodging. (
