小麦是“胎里富”的作物,早种早收,生育期短,生长发育快,这就构成它需肥早,需肥快的特点。由于播种早,地温低,土壤微生物活动弱,土壤中有效养分分解缓慢,满足不了小麦苗期所需养分。因此,小麦施肥,应以种肥为主,追肥为辅,以充分满足小麦生育期间对养分的需要,夺取高产。 1.种肥小麦以氮磷配合作种肥,增产显著。如克山农科所试验,氮磷混合施比单施氮肥增产26.5％。又如1975年肇东县向阳公社百合
Wheat is “rich in the flesh” crops, early planting and early harvest, short growth period, rapid growth and development, which constitutes the need for it early, need fast fat characteristics. Because of sowing early, low ground temperature, weak soil microbial activity, the effective decomposition of nutrients in the soil slowly, can not meet the wheat seedling required nutrients. Therefore, wheat fertilization, should be based mainly on fertilizer, dressing supplemented to fully meet the needs of nutrients during the growth of wheat, to obtain high yield. 1. Kind of fertilizer to nitrogen and phosphorus as a kind of fertilizer, a significant increase in yield. Such as Keshan Agricultural Experiments, nitrogen and phosphorus mixed than single nitrogen fertilizer increased yield 26.5%. Another example is the Zhaoyong commune Lizong County in 1975
