Description

Utilize banana caulo to make compound nitrogen fertilizer synergist PBP method and PBP using method
Technical field
The present invention relates to ornamental plant cultivation technique field, especially relate to a kind of method that banana caulo makes compound nitrogen fertilizer synergist PBP and using method of PBP utilized.
Background technology
Banana is Chinese the fifth-largest fruit, and banana area in 2009 and output are respectively 33.9 ten thousand hectares, 883.4 ten thousand tons of (China's Agricultural commodity yearbooks, 2011), simultaneously, the plantation banana also produces the approximately banana stem leaves of 3,051 ten thousand t, is a kind of very important Biological resources.But for a long time, banana stem leaves fails to obtain reasonable development, but abandon in the field, not only wasted resource but also contaminate environment.In fact, the tannin and the polyphenols that enrich in banana stem leaves juice are good nitrogen fertilizer potentiating agent work materials.
Nitrogenous fertilizer is the indispensable element of agriculture production, China has become world's nitrogenous fertilizer and has consumed the first big country at present, Chinese nitrogenous fertilizer consumption in 2010 be about 4,151 ten thousand tons (pure, lower same), under the at present popular fertilizing method of China, the utilization rate of nitrogen fertilizer of China only has 30%~35% (Geng Zhenguo, 2012), therefore, Chinese loss of nitrogen fertilizer amount was about 2,900 ten thousand tons in 2010, and this has not only greatly wasted resource, simultaneously, also accelerate the acidifying of soil, caused underground water, surface water pollution (Wang Zenong, 2010).
As a rule, denitrification and ammonia volatilization are main loss access, therefore, can control the conversion process of different nitrogenous fertilizer in soil by adding the nitrogen fertilizer potentiating agents such as nitrification inhibitor and urease inhibitor, thereby improve fertilizer utilization efficiency.
Nitrogen fertilizer potentiating agent substantially can be divided into chemosynthesis class and vegetable material and extract class.The chemosynthesis class has hydroquinone (HQ), two hydrogen by polymer substances such as (DCD), 2-amino-4-chloro-6-picoline (AM), N-serve (CP), 0-phenyl phosphoryl diamine (PPD), the cruel triamines of N-butyl sulfo-(BTPT), it is difficult to decomposition and produces residual and accumulation in soil, and contaminate environment is very careful in actual applications.And natural material class nitrogen fertilizer potentiating agent has " green " property, can overcome the negative impact of chemosynthesis class synergistic agent, the patent that present domestic existing publication No. is CNIO1844948A, be that a kind of natural plant material prints the application of element as nitrogen fertilizer potentiating agent of remonstrating with, it remonstrates with element as nitrogen fertilizer potentiating agent with the natural plant material seal, the seal that adds 1~10wt% in the nitrogenous fertilizer element of remonstrating with makes stable nitrogenous fertilizer.In addition, also having publication number is patent-natural plant-carrying compound nitrogen fertilizer synergistic of CN1454880A, its with Leaf of Lemon Eucalyptus, eucalyptus leaves or leaf of tea tree dry powder as plant urease inhibitor, and with the seeds of a tung oil tree dregs of rice, Leaf of Camphortree or Sweetscented Oleander Leaf powder mixture as plant-nitration inhibitor.
