巨峰葡萄果粒大,味道美,深受广大消费者的喜爱。但是巨峰葡萄受天气的影响比较大,坐果率低一直是它的致命弱点。常见提高巨峰坐果率的方法有:喷施多效唑和硼酸、花期环剥、人工授粉等。这些方式不仅费时费工,而且喷施多效唑和硼酸不当会造成坐果太多,后期需要多次疏果。那么,如何做到事半功倍又不影响巨峰的品质呢?据笔者几年实验,认为嫁接改良是提高巨峰葡萄坐果率最好的一种方法。以下以华北地区为例:1.砧木的选择通过实验,在华北地区,用马乳葡萄做砧木改良巨峰效果最为明 Kyoho grape fruit large, delicious taste, by the vast number of consumers. However, Kyoho grapes affected by the weather is relatively large, fruit setting rate has always been its Achilles heel. Common ways to improve the Jufeng fruit set: spraying paclobutrazol and boric acid, flowering girdling, artificial pollination and so on. These methods not only time-consuming and laborious, and spray paclobutrazol and improper boric acid can cause too much fruit, the need for multiple thinning later. So, how to do more with less without affecting the quality of Jufeng? According to a few years of experiments, I believe that grafting improvement is to improve the fruit Jufeng grape the best way. The following to North China as an example: 1. The choice of rootstock Through experiments, in northern China, with horse milk grape rootstocks to improve the effect of the most significant Kyoho
