在果树育苗工作中,有计划的确定合理播种量是很重要的。因为它直接或间接的关系到育成苗木的数量、质量以及育苗的成本。 早在60年代就有人试验指出:果树播种量的计算是依据每亩计划留苗株数,以每kg种子粒数,用种子发芽率估计出的每kg种子田间出苗数,加上疏苗、移植的损耗,确定出成苗数占出苗株数的百分率,从而计算出每kg种子的成苗株数,所求得的每亩计划留苗株数与每kg种子成苗株数的比值,即为每亩播种量。
In the fruit tree nursery work, it is important to plan for a reasonable planting rate. Because it directly or indirectly related to the number of breeding nursery stock, quality and cost of nursery. As early as the 1960s, some people pointed out that the calculation of the planting rate of fruit trees is based on the number of planted leaves per mu planted, the number of seedlings per kg estimated by the seed germination rate per kg of seedlings, Of the seedlings to determine the number of seedlings accounted for the percentage of seedlings per kilogram to calculate the number of plants per kilogram of seedlings planted per plant and the number of seedlings per kg seedling ratio is sown per mu the amount.
