The Research On Different Fertilization Plan In The Growing Period Of Zizyphus Mauritiana Lam

Taiwan blue jujube systematic is named Mao Yezao (Zizyphus mauritianaLam), origins from India, also has thewild distribution in south Burma, Vietnam, Asia, Africa,Australia, and places such as our country Fujian, Yunnan. The Taiwan blue jujube belongs to the Ziziphus jujuba Mill. var. inermis (Bunge) Rehd, which is often green arbor or the big bush, and is the perennialfallen leaf tree. It enjoys the fine reputation of "the tropics small apple" , was considered that it extremely has one of development valueeconomical fruit trees at present.The present paper mainly studies in the Taiwan blue jujube fertilization experiment, aims to use sixteen kinds of fertilization nutrition allocated proportion experiment, and afterthe long time careful observation, adjustment, and the experimentanalyzes the contrast, discovers the most reasonable nutritionallocated proportion, namely find the essential element best allocatedproportion stnicturethe whic can make blue jujube grows healthy, strong and the fast-growing bumper crop. May instruct the planter blue jujube thepromotion, causes it to become the mainly plant which develope the local structure adjustment, rural economy and the farmer additionally incomes.This experiment uses the orthogonal testing method, altogether has 16kinds to apply fertilizer processing, through analysis contrast between the soil entire quantity analysis (nitrogen, phosphorus, potassium,organic matter, the PH value) of Taiwan bluejujube and the Taiwan blue jujube leaf blade's nitrogen, phosphorus and potassium nutritive elements, obtains the best fertilization amounts of Taiwan blue jujube in period of June and September ,the conclusion is: the Taiwan blue jujube Plants in earth, nitrogenous fertilizer 27.3 grams per plant, phosphorus fertilizer 5.89 grams per plant, potassium fertilizer31.95grams per plant, can obviously elevate the nitrogenous percentage in Zizyphus mauritiana Lam leaf; And nitrogenous fertilizer 27.45 grams per lant,compound fertilizer 2.95 grams per plant, potassium fertilizer15.97 grams per plant, can obviously elevate the phospoorus and potassium percentage in Zizyphus mauritiana Lam leaf. In virtue of the mathematical statistic theory to establish the preliminary fertilization model of the Taiwan blue jujube.
