More preferably：The non aqueous carrier, which is equipped with, to be used to enclose between non aqueous carrier and micro- water permeable membrane
Into cavity surround the isolation boards of multiple separate chambers, fertilizer is dispersed in different chamber；One end of the isolation board and non-aqueous
Solubleness carrier encapsulation process, its other end and micro- water permeable membrane encapsulation process.
In conclusion the invention has the advantages that：
Using the present processes, fertilizer is released slowly in soil, the slow dissolution in buffer solution and soil, for growth
In plant slow-absorbing, reduce the application number of fertilizer, reduce labor intensity；Using the present processes, in the soil
Concentration of fertilizer maintains steady state value, and the fertilizer of dissolving is absorbed in time, and then fertilizer, which is redissolved, keeps constant the concentration in soil
Value, and the steady state value is suitable for the growth demand of plant, it is dense that the too low caused fertilizer deficiency situation of reduction concentration of fertilizer also reduces fertilizer
Phenomena such as spending plant burn seedlings caused by height, is conducive to the healthy growth of plant.
