【摘要】 通过番茄(Lycopersicon esculentum Mill.)老株更新套种豆角[Vigna unguiculata(L.)Walp.]的大棚试验,分析了土壤和番茄植株的养分含量以及产量、产值差异。结果表明,在豆角拉秧期,土壤硝态氮、速效钾含量比不套种豆角的分别提高了190.22%、59.62%,差异达显著水平。与不套种豆角相比,番茄套种豆角处理的番茄产量降低了10.33%,但差异不显著。不过由于豆角产量为11 415 kg/hm~2,套种豆角后增加的产值有12 270元/hm~2。所以番茄老株更新套种豆角不仅可以显著提高土壤氮、钾含量,还可以提高产量、产值,增加土地利用率。更多还原

【Abstract】 The nutrient content of soil and tomato(Lycopersicon esculentum Miller) plants and fruit yield treated by old strain pruning technology of tomato intercropped with bean [Vigna unguiculata(L.) Walp.] was analyzed.The results showed that compared with CK,the soil nitrate N and available K was significantly increased(190.22%,59.62%,respectively) in the harvest period.The yield of tomato treated by old strain pruning technology intercropped with bean was decreased by 10.33%.However,the decrease was not significant with CK.The yield of bean was 11 415 kg/hm~2.The economic output value was increased by 12 270 CNY/hm~2 when interplant with beans,indicating that not only could this cultivation method significantly increase the content of soil N and K,but also improved the economic income and land use efficiency.更多还原
