桑果树优质苗木繁育技术

Breeding Technique of High Quality Seedlings of Mulberry Fruit Trees

桑果树是经济价值极高的经济林,在生产中发展前景广阔,为了培养桑果树优质苗木,对其春季繁育技术进行了总结:选择土壤肥力足、通透性好、含水量高、阳光照射条件强的地块作为苗圃地;选择15~30 a树龄,且生长健壮、无病虫害的母树作种子林;桑果树种子播种时期以2月下旬至3月上旬晴天多云的天气为好;做到浇水保湿、遮阴防晒,在幼苗期进行间苗,保证良好的肥水管理,清理除草,科学防治病虫害,减少苗木死亡,确保苗木质量,促进苗木健壮生长。在实际育苗中发现,采用春季播种技术培育的苗木产量高、苗木健壮,该技术当年春季播种,当年10月即可繁育出优质苗木出圃销售,见效快、效益高。

Mulberry tree is an econormic forest with high economic value,and it has a broad prospect in production.In order to cultivate mulberry seedings of high quality,the spring breeding techniques were summarized.The plots with sufficient soil fertility,good permeability,high water content and strong sunlight were selected as nursery land.15-30-year-old mother trees with strong growth and no pests and diseases were selected as seed trees.Mulberry seed sowing period in late February to early March sunny cloudy weather was best.Watering and moisturizing,shading and sun screening should be carried out.Inter seedlings should be carried out at seedling period to ensure fertilizer and water management,clean up weeding,scientifically prevent diseases and insect pests,reduce seedling death,ensure seedling quality,and promote healthy growth of seedlings.In the growing,it was found that the seedling yield was high and the seedlings were robust by using the spring sowing technique.When the seedlings were sowed in the spring of the year,they could be bred and sold in October of the year.
