摘要
[目的]为了研究能使核桃采穗圃产出更多的优质穗条的种植密度和施肥配比模式。[方法]采用裂区设计,以密度为主区因素(A),株行距分别为1.0 m×2.5 m、2.0 m×2.5 m、3.0 m×2.5 m 3个不同密度定植,施肥量为副区因素(B),并将氮、磷、钾不同比例进行搭配。主区为随机区组排列,副区为完全随机区组排列。[结果]种植密度对产穗量的影响在0.01水平显著;施肥配比产穗量的影响不显著;种植密度和施肥配比的交互作用对产穗量在0.01水平显著;当定植密度为3.0 m×2.5 m与施肥量N(100 g)+P(30 g)+K(40 g)组合时,其单株产穗量最高;当定植密度为2.0 m×2.5 m,其平均1 hm2产穗量最高。[结论]选择合理的种植密度和适当的追肥配比,能有效提高采穗圃的效益。
[ Objective] The research aimed to study planting density and fertilizer ratio model which made walnut scion produe more highquality spikes. [ Method] Using split plot design, with density zone factor A, spacing were 1.0 m × 2.5 m, 2.0 m × 2.5 m and 3.0 m × 2.5 m with different density planting. Fertilizing amount was taken as deputy district factor B. Nitrogen, phosphorus, potassium and different proportion were collocated. Main area was random group arranged, and deputy district was completely randomized block arranged. [ Result] The effect of planting density on the yield of cuttings was significant. The effect of fertilization ratio scion yield wasn＇ t significant. The interaction of plant density and fertilizer application was significant on cutting production. When the planting density and fertilization of 3.0 m × 2.5 m was N （ 100 g） ＋ P （30 g） ＋ K （40 g）, the yield per spike was the highest. When the planting density was 2.0 m × 2.5 m, average 1 hm2 scion yield was the highest. [ Conclusion] The reasonable and appropriate topdressing ratio could effectively improve the scion nursery of benefit, which had great practical value.
