板栗化学疏雄板栗疏雄增产的原因，主要是减少过量的雄花对树体水分和养分的大量消耗，使树势增强，叶片增厚，有利于雌花发育。一般雌雄花序比例为１∶１２、花朵比为１∶３４５０。因此，疏去９０％—９５％的雄花，完全能够满足授粉需要。以前大多是人工疏雄，效率很低... Chestnut chemical sparse chestnut Chestnut yield growth reasons, mainly to reduce the excess of male flowers on the tree water and nutrients in large consumption, so that the tree potential increase, leaf thickening, is conducive to female flower development. The ratio of male and female inflorescences is 1:12, and the flower ratio is 1:3450. Therefore, sparse to 90% -95% of male flowers, fully able to meet the pollination needs. Mostly before the man-made, efficiency is very low ...
