鸭梨是河北省的特产,远销国内外,是北方主要果品之一。果实品质如何?向来受到栽培者和消费者的关心和重视。近年来,随着密植试验的开展,有些新梨园也采用了密植栽培方式。但是密植之后,又出现了新的矛盾,高产和优质的矛盾是其中之一。日本林真二等报道,从不同年份的不同气候条件对梨果实品质的影响看,凡是高温日照多的年份比日照不足的年份,糖分含量高得多。本试验着重研究光照强度对鸭梨果实品质的影响。
Pear is a specialty of Hebei Province, sold at home and abroad, is one of the main fruits in the north. Fruit quality? Has always been cultivated and consumers care and attention. In recent years, with the close planting test carried out, some new pear orchards have also adopted close planting methods. However, after close planting, new contradictions have emerged and the contradiction between high yield and high quality is one of them. Japan’s Shinji second class reports, from different years of different climatic conditions on the quality of pear fruit, see, where the high temperature sunshine more than the lack of sunshine years, the sugar content is much higher. This experiment focuses on the impact of light intensity on the quality of Ya pear fruit.
