1. Rice now has its own big data platform,claimed a conference in early April.Led by the China National Rice Research Institute,the platform records data throughout every,stage of rice production,including collection,storage,and analysis.It will also regularly publish reports to improve the service of rice production,providing convenience to farmers.Apart from big data,other technology is aiding agriculture in China in recent years.

Drones(無人機)play an important role in farming this spring. "Using drones to spread the nutrient solution(營養(yǎng)液)is a lot safer than doing it manually(手動地), "Shi Zhenhai,a farmer in Henan who is responsible for about 119 hectares of wheat fields said.Shi added that the flying machines greatly improved efficiency.The more advanced drones that the farmer bought recently can be filled with 50 liters of liquid,which can be used to cover about 3.4 hectare farmland.With four drones working at the same time,it only takes three hours to finish spreading the solution over all of Shi's land.
Monitoring on their own
A smart glass greenhouse used to grow tomatoes features more than 120 patented technologies.Located in Shandong,the demonstration base covers' about 80,000 square meters but requires very few workers.
Sensors collect information about the plants,such as the humidity(濕度)of the environment,the condition of sunlight and heat,and whether the room is ventilated(通風)enough.
It is then uploaded to a platform to be analyzed.The correct levels of water and fertilizer are supplied to crops by the automatic irrigation system,Robots and other devices are used to pick and transport tomatoes.
With facilities to store heat,the structure does not use huge amounts of energy in winter,unlike traditional greenhouses. "Growing crops in a controlled environment enables farmers to produce high-quality plants,maintain high food safety standards,and avoid the use of pesticides," Wang Haiguang at the operations office of the greenhouse said.
