| 摘 要： | 试验表明，长效塑肥具有缓慢释放的特点。对棉花施用长效塑肥，养分供应平稳，防止徒长，生长发育加快，提早成熟，对棉花以的２５％长效塑肥和的速效性肥配合施用，能供给棉花在整个生长期对养分的需要，促进棉花生长发育，明显地提高产量，棉花的籽棉产量比不施肥增产１３７．８６％，比施用等量速效性肥增产５７．３４％．

| Abstract: | The experimental results indicated that long-lasting plastic fertilizer has afesture of releasing nutrition slowly.The application of long-lasting plastic fertilizer to cotton maintained a favorable nutrient balance,protected from excessive growth,speeded updevelopment and subsequently promote early ripe. Twenty -five long-lasting plastic fertilizer in mixture application with readily available fertilizer(ratio 2 to 1)could meet the needs ofcotton nutrient in the whole growth period,improve cotton growth and development,enhanceyield remarkably.The output of ungrind cotton applied long-lasting plastic fertilizer is1 37.86%higher than that of cotton not applied fertilizer,57.34%higher than that of cottonapplied readily available fertilizer. |
