新疆目前山区林木种子工作,基本上处于见种就采,有种就育的后进状态。母树破坏严重,种子质量低,给更新造林带来了有害影响,必须采取措施,使山区林木种子工作走上正轨。 近二十年来,虽然大部分山区林场都建立了森林苗圃,有的还建立了采种母树林。更新造林保存面积为十四万多亩,其中十万亩基本郁闭成林。但由于不重视林木种子品质的遗传改良,没有抓紧优良采种林分和母树林的选划保护工作,随着森林的开发利用,伐优不伐
At present, Xinjiang mountain forest seed work, basically see the seed mining, a kind of backward state of education. The serious destruction of the mother tree and the low quality of the seed have brought detrimental effects on the reforestation. We must take measures to get the forest seed in the mountain to work on the right track. In the past two decades, although most of the mountainous forest farms have established forest nurseries, some have also planted seed-bearing mother trees. Renewal of afforestation preservation area of 140,000 mu, of which 100,000 mu basic canopy closed forest. However, due to the lack of attention to genetic improvement of tree seed quality, no efforts have been made to select and protect good seed-stocking forests and mother trees. With the development and utilization of forests,
