摘要
本文采用二次正交旋转组合设计方法,建立了N、P、K、空间条件、时间条件五项技术措施与马尾松苗木地径关系的数学模型。并应用计算机模拟技术,筛选出苗木地径4.4~4.6mm的壮苗高产配套技术优化组合方案。
Using quadratic orthogonal rotation design, with the aid of computer,this paper established a mathematical model of ground diameter for masson pine (Pinus massoniana),which related to fertilizer nitrogen,fertilizer phosphorus,fertilizer potassium,density and seedling date.Then, a group of optimizing composite cultivation technique for seedling strengthening and high-yielding of masson pine was selected using the computer simulating technique,with ground diameter reaching to 4. 4 ̄4.6mm under the cultivation regime.
