This paper studied the influence to the Zingiber mioga's growing,output and quality with different fertilize dealing,as well as the nutritive peculiarity and manurial effect of legume.The material of this test is Zingiber mioga and quarternary yellow soil which is collected in pineland of Guizhou university with the PH 4.79.In order to finish this test,we investigated the masses,finished pot experiment,analyzed chemical properties indoors and used biostatistics method.The main conclusions was as follows:1.The research indicated that,the content of nitrogen and potassium have biggish difference in different part of Zingiber mioga,and the difference of phosphorus is not obvious.Most of nitrogen and phosphorus are accumulated in the tuberous root,and potassium is mainly accumulated in the overground part.2.The change trend of accumulation quantity of N in Zingiber mioga was S-type due to different treatment of N,P,and K.The trend of the accumulation of phosphorus in Zingiber mioga's leaf and stem tuber is raise-drop-raise.The trend of the accumulation of potassium in legume's leaf and stem tuber is not obvious.The trend of the accumulation of potassium in Zingiber mioga's stem tuber is raise-drop-raise.3.Generalized analysis the nutrient content,biomass and total nutrient absorption of Zingiber mioga in different time,Indicated that no matter which time the nutrient content of various organs in Zingiber mioga all does display for the root＞the leaf＞the stem,but concrete ratio for different organs and different periods vary.No matter which time the nitrogen,the phosphorus and the potassium element content in Zingiber mioga all does display for the nitrogen＞the potassium＞the phosphorus,The content of N is highest in 7-8 months;P in 6-7 months;K in 8 months.4.NPK fertilizer experiments show that:different nitrogen,the phosphorus and the potassium fertilizer amount used has extremely influented the Zingiber mioga output,processes 4 and processes 7 output to be high,the fruit are very big,the fertilizer allocated proportion is the best.nitrogen of 34.41～40kg,phosphorus of 8.8～30kg, potassium 25～75kg each unit of area remarkably enhanced output of the Zingiber mioga.5.Different fertilizer ratio to be extremely obvious to the quality of Zingiber mioga, All of the four indicators,the protein content is affected to the biggest factor is the potassium element,next is the phosphorus element,affects slightly is the nitrogen element;The nitrogen phosphorus potassium to the Zingiber mioga of total sugar content influence size is:Nitrogen＞potassium＞phosphorus;Nitrogen phosphorus potassium to cellulose content influence size is:phosphorus＞nitrogen＞potassium.From this sees,the effect of the phosphorus is increasing the Zingiber mioga cellulose content to be most remarkable,nitrogen and potassium nutrition to be next best;The total acid content is affected to the biggest factor is the nitrogen,next is the phosphorus element,smallest is the potassium element,In the production of the Zingiber mioga,the nitrogenous fertilizer, the phosphate fertilizer and the potassium fertilizer matches executes,but the varying degree improves the quality of the Zingiber mioga.This article has studied different fertilizer of the allocated proportion to the influence of the Zingiber mioga nutrition rule as well as the output and the quality, obtained the most reasonable fertilizer matching of nitrogen,the phosphorus and the potassium,thus instructed the people well to applying fertilizer to the Zingiber mioga rationally.
