1. Preparation of corn seedbed. 2 to 3 days before seeding , the soil is fertile and loose, and the dry land near Honda is used as a seedbed. The ground is first dug and leveled to make a seedbed of 1.3 to 1.7 meters wide. 2 grams of phoxim per square meter to control underground pests.
　　 2. Nutritional soil preparation. Use 30% to 40% of decomposed organic slag, 60% to 70% of fertile fine soil as the substrate, transplant not less than 150 kg of soil per acre of field , and add 1.5 kg of superphosphate , 0.15 kg of urea. After mixing evenly, it is advisable to add the manure water to the "hands to form a mass, touch the ground and disperse".
　　 3. Ways of raising seedlings. Soil organic matter content, loose alluvial soil, Zhaxi Temple and purple soil developed in Penglai Town, etc., can choose floppy seedling transplanting technology ( 100 holes each ); soily sticky yellow soil, red soil and Suining group developed purple soil Etc., using a nutrition cup (bag, tube) seedling technology. The prepared nutrient soil after loading into the nutrient cup or diskette 80% compaction seedbed, were seeded per each cup or 1 to 2 seeds, sprinkle fine soil to cover the seed thickness of not less than 1 cm.
　　 4. Seedbed management. Use the prepared 2 m long bamboo piece to hang the arch on the seedbed, and then cover the 2 m wide agricultural film, and compact it with earth pressure to reduce water loss. The temperature inside the film before the needle is controlled is below 35 °C; after the needle is taken, the temperature inside the film is controlled below 25 °C to prevent burning. If it is not possible to transplant properly in a timely manner (drought or heavy rain, etc.), move the floppy disk or cup in time to cut off the seedlings.
　　 5. Transplanting technology. The best transplanting period of corn seedlings is "one leaf and one heart". When more than "three leaves and one heart" transplanting, 0.1 kg / square meter of urea can be used to increase the application of "send marry water". According to the planned plant spacing, the grading, orientation, and wrong nest transplanting should be carried out after the planting to cover the soil and the nest should be no less than 3 cm to prevent the drought from spreading the fat ball and affecting the root growth.
The technology is suitable for the southwest mountain corn area of ​​Yunnan, Guizhou, Sichuan, Chongqing, etc. When the suitable sowing date arrives, it can not be planted in time due to seasonal drought. The seedling transplanting technology can be used to concentrate the germination, emergence and seedling stage of corn. Management in the seedbed, avoiding the hazards of disasters, and transplanting in time after the rain. If combined with Daejeon mulching technology, the effect of drought resistance and yield increase is more significant.
