Scope

Scope: This document specifies the terms and definitions, environmental requirements for the production site, target yield, pre-sowing preparation, selection of tillage and sowing machinery, sowing, field management, harvesting, and production records for the dry direct sowing of rice in wide and narrow rows in wheat-rice double cropping areas in Nantong City and similar ecological regions. This document is applicable to the production of dry direct sowing of rice in wheat-rice double cropping areas in Nantong City and similar ecological regions. Main technical content: The varieties selected should be approved by provincial-level or higher authorities, have relatively short growth periods, strong stress resistance, and be suitable for planting in this region, such as Nanjing 9108 and Huai Dao No. 5. The seed quality standards comply with the provisions of GB 4401.1-2008. Before straw treatment, the straw should be shredded and scattered evenly when harvesting the previous wheat crop, with a stubble height of ≤30 cm and a straw length of 10 cm~15 cm. For sowing and tillage operations, the 2BFGK-12(6)260 full straw stubble tillage intelligent fertilization sowing machine can simultaneously complete five operations: straw displacement, strip fertilization, tillage, trenching, and wide and narrow row sowing. The general sowing amount per mu is 4 kg~5 kg. The latest sowing date should not be later than June 15, and early sowing within the appropriate period is recommended. The 2BFGK-12(6)260 full straw stubble tillage intelligent fertilization sowing machine is selected for sowing and tillage operations. Before operation, ensure that the whole machine is in good technical condition, and ensure the quality of operation during operation. The working width of the machine is 2.6 m, with 12 rows of wide and narrow row sowing of rice, and a sowing depth of 1 cm~2 cm. When the 2BFGK-12(6)260 full straw stubble tillage intelligent fertilization sowing machine is used with
