【摘要】 针对造成重迎茬大豆减产的两个主要原因 ,即以大豆孢囊线虫为主病虫危害及耕层土壤速效钾、速效锌、有效硼单一消耗 ,而研制开发的肥药结合多功能大豆重迎茬专用肥 (10 - 12 - 8)可显著提高单产 ,改善品质 ,抑制大豆孢囊线虫、根腐病及地下害虫的危害 ,满足重迎茬大豆不同生育阶段对 N,P,K,Mg等大中量及 Zn,B,Mn等微量营养元素的需要。试验示范结果表明 :大豆重迎茬专用肥比农民习惯施肥 (磷酸二铵 +尿素 +氯化钾 )平均增产2 3.5 % ,增产 385 .5 kg/ hm2 ,增收 6 15 .6元 / hm2 ,比等量的磷酸二铵增产 7.8% ,增产 177.1kg/ hm2 ,增收 2 40元 /hm2更多还原

【Abstract】 Aiming at two causes yield decrease which are mainly the pests and diseases with the soybean cyst nematode and single consumption of available potassium, available zinc and available boron the multifunctional specialty fertilizer for alternateyear and continuous croppling on soybean were developed, which can increase unit yield, improve the quality and control the soybean cyst nematode, root rot disease and underground pest, and also provide the soybean with full amount of N, P, K, Mg, Zn, B, Mn. The results of the experiment and demonstration show that the specialty fertilizer can increase yield by 23.5%, 385.5 kg and 615.6 RMB Yuan per hectare than the common fertilizer (ammonium phosphate+urea+potassium chloride) or increase yield by 7.8%, 177.1 kg and 240 RMB Yuan per hectare than the same amount of ammonium phosphate.更多还原
