影响板栗雌雄花序形成因子的研究

通过对板栗枝条生长状况与雌雄花序形成关系的调查和品种、树龄对雌雄花序形成的影响的调查,以及施肥、修剪等试验研究,认为影响板栗雌雄花序形成的主要因子是品种、树龄和树体的营养状况,修剪、施肥等栽培措施能提高结果枝数和雌花序数量,降低雄花序数量。这主要是加强了树体营养所致。

STUDY ON THE EFFECTS OF FACTORS ON THE CHESTNUT (CASTANEA MOLLISSIMA BL.)MALE AND FEMALE INFLORESCENCE FORMATION

According to the investigation of relations of growth state of chestnut branches and male, and female inflorescence formation, the investigation of effects of varieties and tree age on male and female inflorescence formation, and the tests of fertilization and pruning, the authors pointed out the major factors effected male and female inflorescence formation of chestnut were eultivars, tree age and branch growth state. Pruning, fertilization and other culture managements could increace the rate of bearing branches and female iflorescences, reduce the rate of male inflorescences. These resulted from the increase of tree nutritional level.
