在培育苗木的综合农业技术措施中,应该特别注意保证降低播种量的农业技术方法。最近,雪埋法已得到大量推广,这一方法对许多树种(包括落叶松)种子的发芽势和场圃发芽率有好的影响。一九七一年在马加丹的条件下对确定兴安落叶松种子雪埋最适宜的时期和方法进行了研究。把干的和预先在室温水中浸了的种子分别放在冻结和解冻的地上三个月和五个 In integrated agro-technical measures to nurture seedlings, special attention should be given to agro-technical approaches that guarantee reduced seeding rates. Recently, snow burying has been extensively promoted and this method has a good effect on the germination potential and field germination rate of many tree species, including larch seeds. In 1976, conditions and methods for determining the optimal burial depth of Larix gmelinii seeds were studied in Magadan. Seeds dried and pre-soaked in room temperature water were placed on frozen and thawed soil for three months and five
