一、麦的养分吸收将麦的不同生育时期的养分吸收经过,以暖地为例按种类加以观察,则如表1所示。氮素的吸收,在分蘖盛期前,以大麦较为迅速,以后小麦的吸收加快,至孕穗期达到最高吸收量的90%以上。此时,大麦的吸收量只不过最高时的70%左右。但到齐穗期,二者大致均达到92%左右。黄熟期以后,几乎就不吸收了。磷的吸收,大、小麦在生育初期均较氮为少,而到了齐穗期达到90—100%。小麦方 First, the nutrient absorption of wheat The wheat at different growth stages after the absorption of nutrients to warm as an example by type to be observed, as shown in Table 1. Nitrogen uptake, before tillering stage, to barley more quickly, after the accelerated absorption of wheat, booting stage reached the maximum absorption of more than 90%. At this point, the absorption of barley is only about 70% of the maximum. However, to the full heading, both roughly reached 92%. After the ripe yellow, almost not absorbed. Phosphorus absorption, large, wheat in the early growth stage are less than nitrogen, and to full heading 90-100%. Wheat party
