对马来西亚几个油棕园一些1966—67年前定植的林段进行了调查,发现有0—5％的植株不结果实。只有严格选苗才能保证将来单位面积高产。幼苗的一些不良性状 (一)在过渡苗圃阶段和袋育苗圃的早期阶段茎扭曲:这不是遗传性的,而是萌芽种子倒置的后果。曲茎幼苗的叶盘卷,挖开种子周围的泥土,就能看到扭曲的幼茎。叶草状或狭窄:叶狭窄、直立、扁平而象 A survey of some of the palm oil plantations in Malaysia that were planted 1966-67 years ago found that 0-5% of the plants did not produce fruit. Only strict selection of seedlings in the future to ensure high yield per unit area. Some bad traits of seedlings (a) Stem distortions during the transitional nursery and early stages of bag nurseries: this is not hereditary but rather the consequence of the inversion of germinating seeds. Curling leaves of the seedlings of coil coils, digging the soil around the seeds, you can see the twisted young stems. Leaf blade or narrow: leaf narrow, erect, flat and elephant
