Seedling to plant enough fat, increased phosphate fertilizer, with special attention to the effect of quick-raking fertilizer. Per acre applied manure excrement 30-40 Tam, superphosphate 40 pounds or so, zinc-deficient fields per acre increase of zinc sulfate 2 Hall to do rake fat. Seedling at the end of the fertilizer to master the low temperature, field thin and more facilities, high temperature, less application of Tianfei, seedling age to quick-based fertilizer is short, late seedling age, quick-fat with. Seedling top-dressing to master the livestock manure, with appropriate amount of fertilizer, eat less meals, before the light weight principle. The first rooted in fat, the second day after planting with supporting seedlings, make up seedlings, with 200 per acre
