硕士毕业论文，以不同结实能力马尾松无性系为研究对象，开展矮化和施磷肥对马尾松球果产量和雌球花的影响，及其对树体枝梢生长和针叶氮磷营养的变化，为提高马尾松种子园产量和集约化经营提供理论依据。
This master's thesis takes Pinus massoniana clones with varying cone-setting capacities as research subjects, investigating the effects of dwarfing treatments and phosphorus fertilization on cone yield and female strobili of Pinus massoniana, as well as the changes in tree shoot growth and nitrogen and phosphorus nutrition in needles, aiming to provide a theoretical basis for improving the yield of Pinus massoniana seed orchards and promoting their intensive management.
