Cultivation Techniques of High-yield Cultivation in Late Season Single Cropping

Most of the late-season rice cultivation techniques in our province follow the technique of late or late-single-day, so that the potential for increasing rice yield has not been fully explored. Taking the northern Zhejiang region as an example, the differences in the cultivation techniques of single-season late-vegetation and continuous-planting late-seeping (single-vehicle late-seeping) are described below: 1. Early sowing and timely cultivation of strong and vigorous breeding: sowing on May 15th-20th, in northern Zhejiang Province. In Zhejiang and southern Zhejiang, sowing can be delayed. Acres of 30 kilograms will be planted on a per mu basis. 2, reasonable and sparse. Transplanting 74 inches, inserting 2-3 bundles, inserting 20,000 bundles of acres, and inserting 6-8 million seedlings per mu. 3, fertilizer and water management. Add organic fertilizer, apply potash fertilizer, add zinc fertilizer to rotten paddy fields, and adopt the principle of “pre-promoting, middle-control, and post-stabilizing” nitrogen application, that is, Miaofei: returning green manure: dial section fertilizer: panicle fertilizer = 3:3: 2:2, a total of 55-60 tons of nitrogen fertilizer standard fertilizer, 10% more than late, potassium 7.5-10 kg, with phosphate fertilizer. For sandy loam or poorly-fielded plots, the amount of fertilization should also be increased. Timely field baking, generally around July 20th, the number of seedlings will reach about 300,000, and the roasted field will be sorted in batches. Before and after the booting and heading, the shallow water layer shall be maintained in the fields, and the dry and wet periods shall be alternated. Prevent water cut off prematurely, affecting yield and quality. 4. Pest control: In the week before the break to the full heading stage, secondary use of Jinggangmycin to control rice smut disease, and at the same time, the prevention and treatment of rice blast, sheath blight, aphid, and panicle blast were completed.
