在育苗中施行合理密植,是获得丰产壮苗的中心环节之一。1958年大跃进以来,我盟各地苗圃由于解放思想,革新技术,出现了许多高产苗圃,放出了许多丰产卫星。随着生产实践,今后育苗产量质量将一定一跃再跃,而进行密播密留提高单位面积的产苗量,则更要在生产实践中普遍注意。怎样来掌握合理密植?根据不同树种、作业方式、栽培水平去决定不同留苗密度,而获得质量高产量多的苗木是一个值得研究的问题。但是留苗密度的掌握必须均匀、合理,使苗木的个体群体发育得
In the nursery in the implementation of close planting density, is one of the key links to obtain high yield and strong seedlings. Since the Great Leap Forward in 1958, many nurseries in the EU have emerged as many high-yielding nurseries and many high-yielding satellites due to their emancipation of minds and innovative technologies. With the practice of production, the quality of seedling production will leapfrog some times in the future. However, if the quantity of seedling per unit area is increased by close-sowing and close-sowing, it is even more necessary to pay attention to the production practice. How to master the rational close planting? According to different species, methods of operation, the level of cultivation to determine the density of different seedlings, and obtain high quality and yield of seedlings is a problem worthy of study. However, the density control of seedlings must be uniform and reasonable, so that individual groups of seedlings developed
