摘要
为明确新型栽培方式是否能够提高水肥利用效率、降低根区氮磷残留污染,本试验在河北饶阳县日光温室中,以土壤栽培为对照,研究垄嵌和沟嵌栽培模式对番茄产量和收获时根区土壤容重及0~30cm土层土壤硝态氮、有效磷含量的影响。结果表明:3种栽培模式的番茄产量无显著差异,以垄嵌式基质栽培最高;土壤容重随土层深度的增加而增加;与土壤栽培相比,垄嵌式基质栽培和沟嵌式基质栽培的硝态氮累积残留分别降低24.82%和24.44%,有效磷累积残留分别降低46.34%和43.97%。综上,与传统土壤栽培相比,嵌膜式基质栽培是一种低环境代价的生产模式,尤以垄嵌式基质栽培更易于推广应用。
In order to determine whether the new cultivation method could improve water and fertilizer use efficiency and reduce nitrogen and phosphorus residual pollution in root zone,the field experiment was conduct to study the effects of different cultivation modes on tomato yield and change rule of nitrate nitrogen and available phosphorus in root-zone soil of 0~30-cm layer at harvest time.Three cultivation modes were set as soil cultivation(the control),ridging substrate-embedded cultivation and furrow substrate-embedded cultivation.The results showed that there was no significant difference in tomato yield among the three cultivation modes,and the yield was higher under the ridging substrate-embedded cultuvation.The bulk density increased with the increase of soil depth.Compared with soil cultivation,the nitrate accumulation residue in ridging and furrow substrate-embedded cultivation modes decreased by 24.82%and 24.44%,and the available phosphorus accumulation residue reduced by 46.34%and 43.97%,respectively.In conclusion,compared with the conventional soil cultivation,the film-embedded matrix culture was a low environmental cost production mode,especially the ridging substrate-embedded cultivation,which was easier to be popularized and applied.
