Cultivated factor has the influence on the yield and quality of north japonica rice[Ⅶ]--Phosphate fertilizer and magnesium fertilizer which used in seedling stage has the influence on the yield and quality

水稻育苗期施用磷、镁肥对产量和米质的影响试验结果表明,增加磷肥量或施用镁肥可以增加单位面积的粒数,但千粒重下降,对于产量没有影响。而对于提高加工品质,改善外观品质和食味品质有一定的作用。这种影响镁肥的效果好于磷肥。

Make test to research the phosphate fertilizer and magnesium fertilizer which used in seedling stage has the influence on the yield and quality, the result indicated that increase the dosage of phosphate fertilizer and magnesium fertilizer can increase the grains of elemental area, but thousand kerner weight decline, it has no influence on yield. However to increase processing quality, improve exterior quality and gustatorius quality it has definite action. This influence comes through in the effect of magnesium fertilizer is better than phosphate fertilizer.
