Objectives: To study the effects of different sowing methods on seedling yield increasing and explore effective techniques for salt-tolerant seedling cultivation. Tests and treatments: (1) 1500 kg of cropping fertilizer per hectare before plowing; (2) 1500 kg of fertilizer for ditching after tilling; (3) 12 cm of deep ditch after plowing and 1500 kg of concentrated fertilization. Test Methods: Randomized block, repeated three times. Community 30 feet long, 15 feet wide, 10 line area, spacing of 1.5 city ruler, residential area of 0.075 acres. Inter-regional road width 2 feet, the trial area of 0.675 acres. Cultivation and management: Pre-harvest sorghum, harvest after Sept. 12, deal with (1) the district by 1500 pounds per acre shop lap fertilizer. All tests
