黍稷在粮食作物中是生育期最短的作物之一。由于生育期短,施肥宜早不宜迟。因此,推广种肥,增施底肥,适当追肥是黍稷施用肥料的技术要领。一、种肥硫酸铵拌种是常用的种肥。据试验,硫酸铵为种子重量的4倍时出苗正常,为种子的8倍时,出苗迟一天。除了墒情特坏时,每亩以5—8斤的硫酸铵作种肥是不会有副作用的。据试验,用作种肥每斤硫酸铵增产5.3—8.5斤,大大超过了作追肥的增产效果。用碳酸氢铵和尿素作种肥会降低出苗率,因此,不能做种肥用。种肥是速效肥料,只可以满足黍稷幼苗对养分的需求,从长计议,还是远远不够的,
Bream is one of the shortest growing crops in food crops. Due to the short growth period, fertilization should not be late as soon as possible. Therefore, the promotion of kinds of fertilizer, increasing base fertilizer, appropriate top dressing is the technical guidelines for the application of fertilizer millet. First, the kind of fertilizer Ammonium sulfate seed dressing is commonly used species. According to the test, when the ammonium sulfate is 4 times the weight of the seed, the seedling is normal, and when the seed is 8 times, the emergence is delayed one day. In addition to the special moisture conditions, 5-8 kg of ammonium sulfate per acre as a kind of fertilizer will not have side effects. According to the test, for the kind of fertilizer per kilogram of ammonium sulfate increased 5.3-8.5 kg, much higher than for topdressing effect. Using ammonium bicarbonate and urea as a seed fertilizer will reduce the emergence rate, therefore, can not be used as fertilizer. Fertilizer is a quick-acting fertilizer, can only meet the needs of young millet seedlings nutrients, from the long discussion, or not enough,
