杨梅幼树始果年限较长，一般要经８～９年，其间即使有花，亦因其质量差、数量少不能形成产量。因此，采取有效措施促进杨梅早果、丰产是杨梅生产上亟待解决的一大课题。本试验采取螺旋环剥、环割和喷施ＰＰ３３３处理，旨在探讨对东魁杨梅幼树最适宜的促花促果措施。１材...
Myrica arborvitae fruiting period is longer, usually through 8 to 9 years, during which even with flowers, but also because of its poor quality, the number of small production can not be formed. Therefore, to take effective measures to promote the early fruit of Bayberry, high yield is a big problem to be solved in the production of red bayberry. Spiral girdling, ring mowing and spraying PP333 were used in this experiment. The aim was to explore the most appropriate measures for promoting flower growth and promoting fruiting of young bayberry. 1 material ...
