[05:09.76]AN EARLY FARMER PIONEER

[05:14.20]Some people thought Jia Sixie was a lucky man.

[05:19.66]He had worked for the emperor and when he got old,

[05:24.41]he was able to go to his hometown to relax.

[05:29.17]But Jai Sixie had other plans.

[05:33.53]He had always been interested in agriculture

[05:38.49]and intended to do something to make Chinese farming 1 even better.

[05:44.14]Jia Sixie lived in the sixth century AD.

[05:49.78]He was born in Yidu in Shandong Province and worked in Gaoyang,

[05:55.84]which is also in Shandong.

[05:59.31]As he rode through the countryside on his journeys

[06:04.17]for his work he looked out at the fields.

[06:08.90]Some of them were greener and had more crops than others.

[06:14.33]Some cows and sheep looked healthier than others too.

[06:19.59]He was lost in thought.

[06:22.75]How could a farmer get the good crops from his fields?

[06:28.18]Surely there must be rules that helped them.

[06:32.54]He thought he could use his knowledge to find out the best ways

[06:38.79]for farmers to grow crops and then write a book to help them.

[06:45.03]In doing so he collected information from good farmers,

[06:50.70]studied it,and did experiments to find the best way.

[06:55.84]For example,he studied ways of keeping seeds

[07:02.22]and advised farmers to choose seed-heads which had the best colour.

[07:08.07]Then he told them to hang them up to dry all winter.

[07:13.92]The next spring the seeds should be knocked out of their seed-heads and sown 2.

[07:20.89]He studied how to improve the soil.

[07:24.94]He advised farmers to clear weeds from the ground before planting crops.

[07:31.32]They could either let the animals eat the weeds

[07:35.86]or turn the soil over so that the weeds were covered and would rot 3.

[07:42.11]Then he gave advice on turning over the soil.

[07:47.07]The first time each year farmers should dig 4 deeply 5,

[07:52.03]but the second time it should be less deep.

[07:56.29]So the autumn ploughing 6 of the soil should be deeper than the spring ploughing.

[08:02.66]He suggested changing crops in the field every year:

[08:08.12]rive one year and wheat the next so that they would always get good crops.

[08:15.57]They should also grow different plants next to each other in the field.

[08:22.13]He also gave advice on how to fich,

[08:26.38]keep a garden and even make wine.

[08:30.96]He wrote down his advice in a book called QI Min Yao Shu,

[08:37.20]which was considered to be an important summary of the knowledge of farming.

[08:43.36]For centuries after Jia Sixie died,

[08:48.12]it was studied by Chinese farmers and students of agriculture
