Scope

Scope: This standard specifies the production operation requirements for high-quality and high-yield cultivation of salt-resistant Jingzhi 939 rice by machine transplanting, including site selection, land preparation, seedling cultivation, transplanting, fertilization, irrigation, integrated prevention and control of diseases, pests, and weeds, and harvesting. This standard applies to the high-quality and high-yield cultivation of salt-resistant Jingzhi 939 rice in Panjin coastal areas and similar ecological regions. Main technical content: 1. Factory-style seedling cultivation technology: Select seeds with a purity and cleanliness of 99%, a germination rate of more than 95%, and a germination vigor of more than 85%. The seeds should have a moisture content of 14.5% to 15.0%. After sun-drying and removing husks, the seeds are disinfected and soaked in a large germination box. By controlling the temperature and oxygen supply through warm water cycling, the mechanical process of soaking, disinfecting, breaking the chest, and germinating the rice seeds is achieved. Select loess with light salinity, fertile soil, no weed seeds, no stubble, and no herbicide residues. Mix the loess with high-quality composted farmyard manure after crushing and sieving in a 7:3 mass ratio, and add appropriate growth-promoting agents to mix evenly. Each tray requires about 3.5 kg of substrate. Sow the seeds from April 10 to April 15, with 90 g of dry seeds per tray. Pay attention to controlling temperature and moisture in the nursery, strengthening the prevention and control of rice green leaf blight and weed removal. 2. Machine transplanting technology: Transplant from May 15 to May 20, with a row spacing of 30 cm and a hole spacing of (16-18) cm, with (4-5) seedlings per hole, and a basic seedling density of (7.5-10.5) × 105/hm2. The requirements for machine transplanting are dense, shallow, accurate, and full. 3. Fertilization technology: Apply fully composted high-quality fertilizer
