贵州主要红阳猕猴桃园土壤养分状况分析

Soil Nutrient States of the Main 'Hongyang' Kiwifruit Orchards in Guizhou Province

对贵州省主要的红阳猕猴桃产区果园的养分状况进行了测定分析。结果表明:贵阳、水城、瓮安等地果园土壤中有机质含量较为丰富;土壤全氮含量较高,都在1 000mg/kg以上;除水城县鸡场乡果园有效磷含量不到10mg/kg外,其余果园土壤中有效态磷分布较为充足;全省果园土壤富含有效钾;对果实生长发育其主要作用的B、Zn含量充足分布均匀;湄潭果园土壤相对瘠薄,需加强管理。

The soil nutrients states of the main ＇Hongyang＇ kiwifruit orchards in Guihou province were investigated and determined. The results showed that the content of organic matter was abundant in Guiyang, Shuicheng and Wengan, and the total nitrogen contents in the soil were at a higher level more than 1 000 mg/kg. The available phosphorus content was adequate besides the orchard in Jichang town of Shuicheng no more than 10 mg/kg. It was abundant of the available potassium of the whole province. The contents of B and Zn which had a major role in fruit growth and development were adequate. Comparatively, the orchard soil of Meitan was barren： and it required more management.
