公路两旁林带,既美化了路容,且可调节气候,保持水土,保护路基。我区为了快速度、高质量地完成公路林带绿化任务,采用了营养篮育苗。营养篮是把幼苗分床于装有肥料土的篮子里育苗,长高至1.5米以上适合造林时,运往公路林地栽植。它比一般分床苗好,现分述如下: 一、苗期短合浦、海康两地在去年5月底以木麻黄分床于营养篮,30天内由15厘米高增高到60厘来,每天平均增高1.5厘米,其径(直径)高比为1～1.4％左右。5个月高达1.5～2.3米。一般分床苗生长的速度比较缓慢,如茂备市国营苗圃在1959年分床的苗圃苗在1964年6月底观察,一般高为1.7～2.5米,径高比为0.6～0.9％。木麻黄局部发生小枝黄化病。而营
Both sides of the road with the forest, not only beautify the road, and can adjust the climate, maintain water and soil, protect the roadbed. My district in order to speed, high-quality highway forest greening tasks, the use of nutrition basket nursery. Nutrition baskets are sub-bed seedlings in fertile soil with a basket of seedlings, up to 1.5 meters tall for afforestation, transported to the highway planted. It is better than the general sub-bed seedlings, are as follows: First, the seedling short Hepu, Haikang at the end of May last year with casuarina bed in nutrition baskets, within 30 days from 15 cm high to 60% increase, every day An average increase of 1.5 cm, the diameter (diameter) ratio of about 1 to 1.4%. 5 months up to 1.5 ~ 2.3 meters. Generally sub-bed seedling growth rate is relatively slow, such as the state-owned nursery maochao in 1959 sub-bed nursery seedlings observed in late June 1964, the general height of 1.7 to 2.5 meters, diameter to height ratio of 0.6 to 0.9%. Casuarina partial occurrence of yellow branch disease. And camp
