玉米是一种高产作物,需肥量较大,而夏玉米由于麦田套种和抢茬直播,基肥一般不施用,因此科学合理追肥就成为夏玉米获得高产稳产的关键措施之一。一、玉米的需肥量与产量构成生长过程中需要从土壤吸收大量的营养元素,其中以氮、钾元素需要量最多。据实验
Corn is a high-yielding crop, requiring a large amount of fertilizer, and summer maize as a result of wheat interplanting and stubble direct seeding, basal fertilizer is generally not applied, so scientific and rational fertilizer to become high yield corn yield one of the key measures. First, the amount of corn required for fertilizer and production constitute the growth process needs to absorb a large number of nutrients from the soil, of which nitrogen and potassium needs the most. According to the experiment
