摘要: 为明确不同肥料种类及其相互配合追施提高花生产量的效应,确定适宜的追施肥料种类和配施方式,为花生科学施肥提供理论依据。在大田覆膜滴灌条件下,于花针期设置追施氮、钙、硼肥及其相互配施处理,研究了不同处理对花生生长和产量的影响。结果表明,与单独追施氮、硼、钙肥相比,三种肥料配合施用后单株果针数、结果数和荚果干重分别增加了18.61%~24.0%,12.50%~23.00%和12.13%~21.60%,进而提高了产量,且氮、钙和硼肥配合施用促进了花生的地上部干重、主茎高和分枝数,有利于各器官干物质积累,故以花针期追施一定比例的氮硼钙肥或氮钙肥能够有效促进花生营养生长并提高产量。

Abstract: To clarify the effect of topdressing with different fertilizers on peanut yield combined with drip irrigation under film, field experiments were carried out in Jiaozhou, Shandong Province. Mono-application of nitrogen (N) , calcium (Ca), and boron (B) fertilizers, combined application of NCa, NB, BCa, and NBCa were set at the flowering stage, treatment of no irrigation and no topdressing was set as CK1, only irrigation wihtout topdressing as CK2. Yield and related agronomic traits were analyzed under different topdressing treatments.The results showed that, compared with mono-topdressing, combined topdressing of N, B and Ca increased the pins per plant, fruits per plant and dry weight of pods by 18.61%-24.0%, 12.5%-23.0%, and 12.13%-21.60% respectively, thus increased the yield. Meanwhile combined application of three fertilizer increased the shoot dry weight, main stem height and branch number of peanuts, which could help to a better accumulation of the dry matter accumulation of each organ. In conclusion, the combined application of NBCa or NCa fertilizer at the pod-pin stage could effectively promote the growth of peanut and increase the yield. This study will contribute to determine the appropriate topdressing fertilizer types with drip irrigation under film.

Key words: peanut, drip irrigation under mulch, topdressing species, growth, yield
