我场从一九七一年开始落叶松育苗,所走过的路子是一年失败、二年见效、三年成功、四年提高。一九七三年到一九七六年四年共播种落叶松4、6亩,总产苗量140万株,平均每亩产苗30万株,一般当年苗高20厘米。这一事实充分说明:“科学有险阻,苦战能过关”。 一、选择育苗地是否得当,直接关系到落叶松育苗的成败。 育苗地是苗木赖以生长的基础。育苗地是否适当,直接关系到落叶松育苗的成败。一九七一年我们是在水源不足的沙土地里育的苗,由于地不保水,灌溉条件又差,为浇水费工不少,但还是前边浇后边
My field from 1970 Larix nursery, the path taken by the failure of a year, two years to bear fruit, three years of success, four years to raise. From 1973 to 1976, a total of 4,6 mu of larch plantings were sown, with a total output of 1.4 million seedlings. The average seedling production per acre was 300,000, with a typical height of 20 cm. This fact fully proves: “Science has the danger, struggling to cross the border.” First, the choice of nursery or not, is directly related to the success of larch nursery. Nursery seedling is the basis for growth. Nursery is appropriate, is directly related to the success or failure of larch nursery. In 1981 we were nursery seedlings in the under-water sandy land. Due to the lack of water and poor irrigation conditions, we did a lot of work to water the wad
