为了培育抗寒砧木,我省一些地方准备采用山葡萄或山葡萄杂种后代的种子培育砧木苗,现将葡萄种子催芽育苗的做法介绍于下,供各地参考。一、快速育苗法也叫温床(冷床)育苗定植法。辽南旅大地区在三月上旬播种,中北部稍晚。播前先备好温床(或冷床)并提前十天至半月把沙藏种子取出催芽。床土要肥沃、深厚、较疏松。播种后床内要施药饵消灭蝼蛄等害虫。葡萄种子催芽适温为25～28℃。催芽前可先用30℃左右温水浸泡一昼夜。然后把种子用筛过的洁净河沙以一比三到四的比例拌好,放花盆内,盖上玻璃片。
In order to cultivate cold hardwood stockings, some areas in our province are going to adopt the seed of the hill grape or mountain grape hybrid progeny to cultivate the rootstock seedling. Now the grape seed germination nursery practice introduced below for reference. First, rapid nursery method is also called hotbed (cold bed) nursery colonization method. Liaonan Luda area sown in early March, North Central later. Prepare hotbed (or cold bed) before sowing and remove the sand-seed from germination for ten days to half a month. Bed soil to be rich, deep, more loose. Seedbed after sowing to kill bait and other pests. Germination of grape seed suitable temperature 25 ~ 28 ℃. Pre-germination can be about 30 ℃ with warm water soak for a day and night. Then the seeds with a clean sieve of sand to a ratio of one to three to four mix well, put the flower pots, covered with glass.
