为了促进我省板栗生产的发展,现将栽培技术介绍如下。一、育苗过去板栗多实生繁殖,所以品种退化,栗果变小。今后栽培板栗应采用嫁接方法培育苗木,即从丰产性能良好和无病虫害的树上采集充分成熟。自行落下的果实,挑选出饱满的种子,用湿沙拌起,堆放在冷凉的室内,土壤封冻前移入窖中。到播种前5—7天,取出筛去混沙、剔除腐烂种子,然后进行漂选(倒入盛有清水的缸中,除去漂浮起来的种子),捞出沉淀的种子与3份沙子混合放于20—25℃的地方(火炕、锅炉房、向阳处均可),覆盖一层湿麻袋进行催芽,3—5天便可发芽。这时就可按10×30—45厘米的株行距开沟点播,种子要
In order to promote the development of chestnut production in our province, the cultivation techniques are introduced as follows. First, nursery pasture more live reproductive, so the variety of degradation, smaller chestnuts. Future cultivation of chestnuts should be used to cultivate seedlings nursery stock, that is, from the tree with good yield and pest-free trees fully mature. Self-falling fruit, pick out the full seeds, mix with wet sand, stacked in a cool indoor, soil before moving into the cellar frozen. 5-7 days prior to sowing, remove the sieve to remove the sand, remove the rotting seeds, and then drift (pour into the tank with water to remove the floating seeds), remove the sediment seeds mixed with 3 parts of sand Place at 20-25 ℃ (Oven, boiler room, sunny place), covered with a layer of wet sack for germination, 3-5 days can germinate. At this time can be 10 × 30-45 cm spacing ditch on-demand, seed to be
