摘 要:为提高黑松(Pinus thunbergii)种子园种子产量和品质,以黑松初级种子园为研究对象,采用正交试验设计,开展氮(N)、磷(P)、钾(K)、镁(Mg)和硼(B)配比施肥试验。结果表明,不同处理对种子产量和品质影响较大;单粒球果重、单株球果数量、单株球果产量、单株种子产量和种子千粒重在不同处理间均差异显著或极显著。所有施肥处理的种子千粒重均高于CK。T11、T7和T15处理的单株种子产量较高,分别为CK的2.06、1.92和1.77倍,其母树综合性状均较好。在黑松种子园中,可根据种子园的土壤营养状况,对这3个处理进行优化,提高黑松良种的产量和品质。In order to improve seed yield and quality in seed orchard of Pinus thunbergii,orthogonal test was adopted in P.thunbergii primary seed orchard and formula fertilization experiments of N,P,K,Mg and B were carried out.Results showed that effects of different treatments on seed yield and quality were significant.Weight of per corn,number of cones per plant,yield of cones per plant,yield of seeds per plant and weight of thousand seeds had significant or extremely significant differences among different treatments.Weight of thousand seeds of all fertilization treatments were higher than that of CK.Yields of seeds per plant in T11,T7 and T15 treatments were 2.06,1.92 and 1.77 times higher than that of CK.Integrated traits of mother trees in T11,T7 and T15 treatments were better.In P.thunbergii seed orchards,it was suggested that according to soil nutrients of seed orchards,these three fertilization treatments could be optimized to improve yields and qualities of P.thun⁃bergii improved varieties.
