核桃落果严重、座果率低的原因是风害和营养生长过旺。其危害不是直接的机械损伤 ,而是核桃的叶面积大 ,蒸腾失水严重 ,营养消耗过大 ,造成大量落花落果所致。对此 ,我们用摘叶的方法探求去叶提高座果率的影响 ,以期提高核桃的产量 ,加速核桃的发展。试验于 1997～ 1999年在平 Walnut serious fruit drop, fruit set rate is due to low wind damage and vegetative growth. The harm is not a direct mechanical damage, but the walnut leaf area, severe transpiration dehydration, excessive nutrient consumption, resulting in a large number of falling off fruit caused. In this regard, we use the method of pick leaves to explore the effect of removing leaves to improve the fruit set rate, in order to improve the yield of walnut and accelerate the development of walnut. Test in 1997 ~ 1999 in the flat
