A fixed site field experiment was conducted to study the effects of different fertilizers on soil fertility in wheat/maize strip intercropping and soil fertility improvement ways.The results showed that:① when no fertilizer was applied,soil fertility in strip intercropping decreased rapidly and crop yields decreased greatly;② the maize yield took 61.7% of strip intercrop yield,on average,with greater dependence on fertilizers comparing with wheat;③ N fertilizer plays a decisive role...

A fixed site field experiment was conducted to study the effects of different fertilizers on soil fertility in wheat/maize strip intercropping and soil fertility improvement ways.The results showed that:① when no fertilizer was applied,soil fertility in strip intercropping decreased rapidly and crop yields decreased greatly;② the maize yield took 61.7% of strip intercrop yield,on average,with greater dependence on fertilizers comparing with wheat;③ N fertilizer plays a decisive role to strip intercrop yields,especially to maize yields,whose contribution rates reached 55.2% ̄80.9%; ④ The response of wheat to P fertilizer is greater that that of maize,but the response of maize to K fertilizer is greater;⑤ Combination of organic with inorganic fertilizers,and equilibrium of N,P,and K fertilization with N as the pricipal are the basic to the soil fertility improvement in strip intercropping.

采用定位试验研究了不同肥料对小麦/玉米带田土壤肥力的影响及土壤培肥途径。结果证明:①带田不施肥时,肥力迅速降低,产量急剧减少;②在带田的产量构成中,玉米平均占61.7%,且其对肥料的依赖性远大于小麦;③氮肥对带田产量特别是玉米产量起着主要作用,产量贡献率达55.2%~80.9%;④小麦对磷肥反应明显,玉米对钾肥反应明显;⑤有机肥料与无机肥料结合,以氮肥为主,氮、磷、钾平衡施肥是带田土壤培肥的基本途径

Experiments showed that sole application of inorganic fertilizer can maintain high yields of wheat/maize in strip intercropping. But to promote the accumulation of organic matters in soil,inorganic fertilizers should be applied in combination with organic fertilizer.The loss rate of N fertilizer in strip intercropping are no less than 42.1 ̄54.7% suggested that the improvement of fertilizer application methods and increase of utilization ratio of N fertilizer are still a key problem in rational application of...

Experiments showed that sole application of inorganic fertilizer can maintain high yields of wheat/maize in strip intercropping. But to promote the accumulation of organic matters in soil,inorganic fertilizers should be applied in combination with organic fertilizer.The loss rate of N fertilizer in strip intercropping are no less than 42.1 ̄54.7% suggested that the improvement of fertilizer application methods and increase of utilization ratio of N fertilizer are still a key problem in rational application of fertilizers in wheat/maize strip intercropping.Application of P fertilizer,especially combination of inor ganic P fertilizer with organic fertilizer,is an effective practice to increase soil P fertility,which can increase the content of organic P in soil,increase the proportions of available,slowly available portions in inorganic P, and lower the proportion of hardly available portions.Application of K fertilizer is also important because of its heavy comsuption.

研究表明,单独施用无机肥料虽可保持带田高产,但只有与有机肥料配合时才能促进土壤有机质的积累;带田生产中氮肥损失率不低于42.1%~54.7%,说明改进施肥方法、提高氮肥利用率仍是带田合理施肥的关键;施用无机磷肥特别是与有机肥配合施用是提高土壤磷肥力的有效措施,可提高有机磷含量及其占总磷量的比例,提高无机磷中有效及缓效组分所占比例,降低难溶组分(Ca10-P,O-P)的比例;带田耗钾强度高,必须注意钾肥的投入

year wheat/maize strip intercropping field experiments showed ① Rational rate of N fertilizer application in the first year with single application or application in years was 450 kg N/hm 2 for wheat/maize strip intercropping;② The key factors of residual effects and sustain after one time application of N fertilizer depend mainly on the application amount of N and soil nutrient holding capacity; ③ The first year utilization ratio of N fertilizer with different application amount and differently...

year wheat/maize strip intercropping field experiments showed ① Rational rate of N fertilizer application in the first year with single application or application in years was 450 kg N/hm 2 for wheat/maize strip intercropping;② The key factors of residual effects and sustain after one time application of N fertilizer depend mainly on the application amount of N and soil nutrient holding capacity; ③ The first year utilization ratio of N fertilizer with different application amount and differently distributive application ways is 5.7 ̄20.0% lower than that of accumulative utilization,and the residual effects should be taken into consideration when the utilization ratio is evaluated; ④ Application of certain amount of N fertilizer in years had much better results than single application only in the first year.

3年小麦/玉米带田定位试验研究明确了①每公顷总量分别为450、900和1350kgN的氮肥第1年一次性施用和分年施用的增产效果,每公顷450kg左右N为带田适宜施氮量;②一次性施用氮肥后的残效、影响残效大小及持续性的主要因素是氮肥用量及土壤保肥性;③不同用量及不同分配方式氮肥的当年利用率比累积利用率低5.7%~2.0%,评价氮肥利用率的高低时,应将残效考虑在内;④等量氮肥分年施用与一次性施用相比,增产效果及氮肥利用率高得多
