大棚番茄老株更新套种豆角对养分含量及经济效益的影响

The Effect of Intercropping of Tomato Old Strain Pruning with Bean in Greenhouse on Economic Benefit and Nutrient Content

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。

The nutrient content of soil and tomato（Lycopersicon esculentum MiUer） 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/hm2. The economic output value was increased by 12 270 CNY/hm2 when interplant with beans, indicating that not only could this cuhivation method significantly increase the content of soil N and K, but also improved the economic income and land use efficiency.
