不同调节剂和施肥量对惠州引种番木瓜生长的影响

Effect of Different Regulator and Fertilizer on the Growth of Carica papaya Introduced in Huizhou

对惠州地区引种番木瓜进行了不同调节剂对种子萌发和不同施肥量处理对其生长的影响研究,调查了发芽率、发芽势、冠幅、冠层厚度、叶量以及开花结实情况。结果表明:1 mg.L-16-BA处理对番木瓜萌发效果最好,发芽率、发芽势分别达到90%、87%;以每株施肥100 g和200 g的处理对冠幅和叶量增长效果较好,施肥对冠层厚度的增长影响较小,每株施肥200 g对单株开花结实量的增加效果较好。

The experiment of different regulators on germination and fertilizer on growth of Carica papaya was carried out in Huizhou area.Some growth indexes were investigated in the experiment,including germination rate,germination potential,crown diameter,crown depth,leaf quantity,inflorescence and fruit yield.The results showed that 1 mg·L-16-BA was the best on the Carica papaya germination,which germination rate reached 90%,and germination potential reached 87%,respectively.Among the different treatments of fertilization,100 g and 200 g fertilizer per plant were the better treatments for the increments of crown diameter and the leaf quantity.There was less effect of fertilization on the increase of crown depth.The better effect on the amount of flowers and fruits was got with 200 g fertilizer to the single plant.
