为了给作物幼苗生长创造良好的营养条件,人们在播种时往往随种施肥,这就是所谓的种肥。各地经验表明,种肥有用量少、省工、施用方便、增产作用大等优点。种肥的施用方法有三种:一是肥料和种子分开施,先施肥再盖上一层土然后播种;也可以先播种再于种子上施肥;还可以把肥料和种子间隔3～6厘米并行施在另一垄沟里。二是肥料和种子混合施,要求肥料干燥,不易结块,最好用颗粒肥料。二是种子包肥施法,即在播种前先把肥料滚包在种子表面,然后播种,多用于微量元素和菌肥拌种。
In order to create good nutritional conditions for the growth of crop seedlings, people often fertilize with the seed when they are sown, which is what is called seed fertilizer. Experience from all over the country shows that it is advantageous to use less fertilizer, save labor, facilitate application and increase production. There are three kinds of fertilizer application methods: First, fertilizer and seeds separately Shi, first fertilize and then covered with a layer of soil and then sown; also sowing and then fertilize the seeds; fertilizer and seeds can also be separated by 3 to 6 cm In another ditch Second, fertilizer and seed mixed facilities, requiring fertilizer dry, not easy to agglomerate, it is best to use granular fertilizer. The second is the seed package fertilization, that is, prior to sowing the seeds of fertilizer rolling package surface, and then sown, and more for trace elements and fertilizer dressing.
