摘要
沼泽土有机质含量高,保水保肥力强,含氮高,含磷、钾低,而且低湿冷凉,导热性差,前期升温慢,后劲大。因此,沼泽土种稻前期生长缓慢,后期徒长、贪青、产量低。新型水稻BB肥C型是沼泽土稻田专用型,含沼泽土专用改良剂。底肥、分蘖肥、穗肥四部分,具有提升地温、加速养分释放,平衡提供水稻全生育期营养的作用。试验表明:沼泽土稻田使用新型水稻BB肥C型,返青快,分蘖早,适时成熟,产量显著提高。
Cativated marshland contains much organic matter, and it has high capability to preserve moisture and nutrient. Itcontains much Nitrogen but less Phosphorus and Potassium. Cultivated marshland is low-lying and cold, and its temperature goes up slowly in earlier stage of rice growth, so rice grows slowly in earlier stage and ripen late, and the output is low in it. Type C of the New Type Rice BB Fertilizer is special used in cultivated marshland,it contains marshland ameliorayor,basis fertilizer,tillering fertilizer and spike fertilizer, so it can raise ground temperature, accelerate nutrient release and Supply balance nutrient for rice growth. This experiment has proved that the rice turns green quickly,tiller early and ripen in good time in cultivated marshland with the New Type Rice BB Fertilizer and the rice output is increased notably.
