为了摸清谷子需肥规律,实行科学施肥,以争取粮草双丰收,我们建立了由贫下中农、知识青年与科技人员共同参加的高指标的丰产田,获得了亩产1,063斤的成绩,在此基础上我们对谷子在不同生育期内干物质的积累以及对氮磷的吸收和运转情况进行了测定分析,现将结果总结如下: 一、谷子生长期内干物质的变化谷子播种后,经过5天种子就开始萌动,籽粒重量开始下降,幼芽幼根开始伸长;经过19天后谷粒内的养料全部耗尽,只剩下空壳。这时地上部已长出一心一叶(一般把此期称为“离
In order to find out the regularity of fertilizing for millet seeds and implementing scientific fertilization in order to win the double harvest of forage grass, we established a high-yielding high-yield field with poor middle peasants, young intellectuals and scientific and technological personnel participating in the project. The result was 1,063 kg per mu Based on our analysis of the accumulation of dry matter in different growth stages of millet and the absorption and operation of nitrogen and phosphorus were measured and analyzed, the results are summarized as follows: First, the millet growth period of dry matter changes After millet sowing, after 5 The seeds began to germinate, the grain weight began to decline, and the young shoots began to elongate. After 19 days, all the nutrients in the grains were exhausted, leaving only the shell. At this time, the ground has grown one heart and one leaf (generally referred to as "leave
