本文总结了日本长野、山形、枥木三县施行巨峰树体营养诊断标准的试验结果。 1.调查内容影响巨峰葡萄结实和品质的主要因子极其复杂,要全部弄清非常困难。因此,树体营养诊断项目以果农容易掌握为前提,结合以往研究成果和实践,设计调查项目如下:结果母枝的长度、发芽率、开花期,新梢停止生长、叶重、叶面积、叶色、果穗数、果穗和果粒重、着果率、果色、含糖量、含酸量,叶片和土壤的营养分析。
This article summarizes the experimental results of the diagnostic criteria of Jufeng tree nutrition in the three counties of Nagano, Yamagata and Tochigi in Japan. 1. Survey The main factors affecting the firmness and quality of Kyoho grapes are extremely complicated and it is very difficult to find out all of them. Therefore, the tree nutrition diagnosis project is based on the prerequisite that the fruit growers are easy to grasp. Based on the previous research results and practices, the design investigation items are as follows: Results Length, germination rate, flowering stage, shoot growth stop, leaf weight, leaf area, Color, number of ears, ear and fruit weight, fruit rate, fruit color, sugar content, acid content, leaf and soil nutrition analysis.
