NOVELTY - Method for improving sloping field and planting selenium-rich vegetables and fruits involves (a) preparing land for plantation by digging soil, (b) planting selenium-rich vegetables and fruits in prepared land at regular interval, and applying fertilizer comprising green manure, livestock manure, and composted soil, (c) applying diluted fertilizer comprising ammonium sulfate on planted seedling, and (d) performing irrigation, and fruiting management, and performing fermentation for 70 days.    USE - The method is useful for improving sloping field and planting selenium-rich vegetables and fruits (claimed).    ADVANTAGE - The method enables to improve sloping field and planting selenium-rich vegetables and fruits with high yield and quality.    DETAILED DESCRIPTION - Method for improving sloping field and planting selenium-rich vegetables and fruits involves (a) preparing land for plantation by digging soil, where the soil is dry soil, peat, and loam soil in a ratio of 1:0.4:0.2, and adding 4 kg selenium-enriched green manure, 0.8 kg lime, 4 kg livestock manure, 0.5 kg cake fertilizer, and 5-10 g sodium selenite, where the soil is digged longitudinal direction along planting land with regular interval, the land is provided with flowing water gap, groove wall, water channel, spray pipe, pipe portion, shower nozzle, (b) planting selenium-rich vegetables and fruits in prepared land at regular interval, where the planting is performed at row spacing of 1.5-2 cm, seedling height of 20-22 cm, and applying fertilizer comprising 150-155 pts. wt. green manure, 30-35 pts. wt. livestock manure, and 5-9 pts. wt. composted soil, (c) applying diluted fertilizer comprising 5% ammonium sulfate on planted seedling at a rate of 90-100 kg, and soaking in solution comprising 1 kg Bacillus subtilis, 1.5 g ammonium molybdate for 4-4.5 hours, and applying fertilizer comprising green manure, lime, livestock manure, and sodium selenite, (d) performing irrigation, and fruiting management, and performing fermentation for 70 days.
