i already built a greenhouse by using the Arduino mega. Is their any way to receive the data (TEMP,HUMI,SOIL MOSIUTRE) from the system to a smartphone ?

Bluetooth ?
It all depends on distance.
You could use Bluetooth as suggested by @UKHeliBob or WiFi if you are close.
Put a simple webpage on the Arduino attach it to the Internet and view from anywhere.
Getting SMS when alarm levels are reached is probably a good option e.g. water low, water very low, help.
The advantage of SMS notifications is that you don't have to keep checking but get notified when important things have happened.
Have the greenhouse host a simple web page, as done by forum member CatweazelNZ.
The web site seems to be down at the moment, though.
I was thinking about using wifi-shield and connecting it to my arduino to send date by using Blyink.
but which wilf-shield will be the best for doing this task.

I don’t think there is any difference between shields in this respect.
You might consider using a NODE-MCU instead. It can probably do the job by itself and you can use Arduino for something else. I believe it is cheaper than any WiFi shield.
Most WiFi shields will be built around the ESP8266 processor anyway - can just as well use a NodeMCU or WeMOS D1 right away.
I stopped to read about greenhouse, seems this thread is not about greenhouses.
