核桃是重要的木本油料树种之一。我省的核桃树分布范围广,产量也较高,但结实较迟,在一般情况下十年左右才开始挂果,而且品种的数量和质量不能满足生产发展的需要。为此,我们于一九六四年秋开始进行新疆核桃的引种工作,现将引种试验结果整理如下。一、引种试验地自然概况试验地设在蒲县山中公社自家庄大队,其地理位置为北纬36°25′,东径110°54′,海拔1130米,属寒温干燥气候区,冬季寒冷、干旱,夏季较热,雨水多集中在七、八月间,常有春旱秋涝现象。从引种地与原产地气象因子比较看(表一),新疆核桃对于该地气候条件是基本适应的。
Walnut is one of the most important woody oilseeds. In our province, the walnut tree has a wide range of distribution and high yield. However, it is late in the development. In general, the walnut tree begins to bear fruit about ten years or so, and the quantity and quality of varieties can not meet the needs of production development. To this end, we started the introduction of walnut in Xinjiang in the autumn of 1964, and the results of the introduction test are summarized as follows. First, the introduction of the test site to test the natural profile of the trial was located in Pu County Hill commune itself Zhuang Brigade, its geographical location of 36 ° 25 ’north latitude and longitude 110 ° 54’, 1130 meters above sea level, is a cold and dry climate zone, cold in winter, Drought, hot in summer, rain and more concentrated in July and August, often the phenomenon of spring drought autumn floods. From the introduction of meteorological factors and the origin of comparison (Table 1), Xinjiang walnut climate conditions for the area is basically adapted.
