一、细致正地,加深耕层翻前处理好在子,在原垄沟深串一梨,15-20厘米,破在掏墒合成四方头垄,镇压保墒,达到上暄下实,上干下温有较存厚的活土层,有利贮水保墒,根系下扎,有利抗旱。二、增施肥料、农化结合要实现夏玉米春种高产,达到种1保2,种1得5,种1保6的目的,必须是以肥保密,以密夺高产、增施肥料,以农肥为基础,农化结合,种地养地结合,施肥量,优质农肥亩施2000-4000斤,化肥150-200斤,氮、磷、钾配合比例4∶2∶4,缺锌地块亩施锌肥2斤,施肥方法,农肥做底肥一次性施入,化肥分次分层施入,底肥三分之二,农肥三分之一,底肥100斤与农肥混合分层施入,底肥50%,中层30%,种肥20%,与种子隔开,避免烧籽,烧芽,影响幼苗,在底肥的基础上,进行两次追肥,亩追尿素50-80斤,第一次在夏6-7叶追施三分之一,11-12叶期追肥施三分之二,重追穗粒肥,生长期间,看苗喷施液肥,三叶期(断乳期),喷植物动力2003,1000倍液
First, meticulously and deepen the plow tillage treatment is good, in the original ditch deep string of a pear, 15-20 cm, breaking the synthesis of synthetic square sidings furrow, suppression of soil moisture, to Xuan Xuan under the real dry on the next temperature There is a relatively thick layer of living soil, water storage benefits, under the root bar, favorable drought. Second, the increase of fertilizers, agroforestry to achieve high yield of summer maize spring to achieve a species of Paul 2, a species of 5, a species of Paul 6 the purpose must be based on fertilizer confidential to dense high yield, fertilizers, Fertilizers based on the combination of farming, planting and breeding, fertilization, high-quality agricultural fertilizer 2000-4000 kg fertilizer, fertilizer 150-200 kg, nitrogen, phosphorus and potassium with the ratio of 4: 2: 4, zinc deficiency plots Mu of zinc fertilizer 2 pounds, fertilization methods, fertilizer at the end of a one-time application of manure, fertilizer sub-grading Shi Shi, two-thirds of the base fertilizer, agricultural fertilizer one-third of the base fertilizer 100 kg mixed with agricultural fertilizer stratified application of base fertilizer 50%, the middle 30%, 20% of seed fertilizer, separated from the seed, to avoid burning seeds, burning buds, seedlings, on the basis of the base fertilizer, two top dressing, Summer 6-7 leaf chasing one third, 11-12 leaf top dressing two-thirds, heavy grain ear fertilizer, growth period, see seedling spraying liquid fertilizer, clover period (weaning), spray plant dynamics 2003,1000 times solution
