根据错海林木良种基地小区试验和中试结果认为：喷施稀土、满果粉对提高球果、种子产量和种子质量均有明显的效果；在小试的４种剂型和中试的３种剂型中，均以满果粉和农乐效果最好，产种量比对照有提高：樟子松２２．１％～４７．０％、长白落叶松１３．４％～５０．５％；在樟子松种子园中，出种率、千粒重、发芽率及发芽势分别比对照提高８．７％、１３．９％、２７．０％、３０．３％；在长白落叶松种子园中，出种率、千粒重、发芽率、发芽势分别比对照提高２．４％、２８．３％、７．７％和６．３％；在促进结实提高产种量上，最佳浓度均为０．０５％。经测算，樟子松种子园和长白落叶松种子园中投入产出比分别为１∶４和１∶８，经济效益显著
According to the plot trial and pilot-scale results of the wrong hailin wood seed base, spraying rare earth and full fruit powder have obvious effect on improving cones, seed yield and seed quality. In the four kinds of small test and three kinds of pilot test , The fruit powder and agronomic effect were the best, and the seed yield was increased as compared with the control: 22.1% -47.0% of Pinus sylvestris and 13.4% -50.5% of Larix olgensis; Pine seed orchard, the seed rate, grain weight, germination rate and germination potential were increased by 8.7%, 13.9%, 27.0% and 30.3% respectively compared with the control; in the Changbai larch seed orchard, The rates of grain weight, 1000-grain weight, germination rate and germination energy were increased by 2.4%, 28.3%, 7.7% and 6.3% respectively compared with the control. The best concentrations were 0.05 %. It is estimated that the input-output ratio of Pinus sylvestris var. Mongolica and Changbai larch seed orchards is 1: 4 and 1: 8, respectively, with significant economic benefits
