Farm size• Household num.: 2.5×109
• Ave. ferm size: 0.5 ha• Land pieces per family: 5.7
1.Background Smallholder farmer, working for food security of China
Farmer • Less educated• Mainly women
and old people
Field • large variation
Crop production• Low yield and
low efficiency

Step3: Organization of the farmers: develop agricultural producers’ cooperative
land machine farmers ①Land transference ②Machinery cooperative ③Farmers’ cooperative

Step4: Give the farmers hand by hand service during the growing seasons

Step5: Cooperate with local government and Fertilizer company to enlarge new technology extension
Mr Bai, the head of Quzhou
County, introduced the
DH organized by STB to Mr Zhang, the vice governor
of Hebei province
①STB and new technology give confidence to local government and the action of STB became the action of local government
②STB help fertilizer industry optimize their products and training staff to improve there service to farmers

“万亩方田麦进仓,农民个个喜洋洋。今年丰收来不易,老天天气帮倒忙。冬雪早下春天寒,过年双冻接连三。看着小麦要绝产,农民上头做了难。领导重视经常看,农大师生第一线。广播宣传地里转,科学管理送田间。地头打起抗大学,取得粮食来高产,比打日本还作难,地头老师来上课,科学管理来普及。换来这样的好良田。平均产量千把斤,高产地块更高产。
农大扎根在曲周,科技指导保丰收,玉米囤满麦屯鼓,幸福生活有奔头,吃水不忘挖井人,农大功绩垂千秋
三夏当中人倍忙,又收又种忙断肠,科技指导是指南,一天到晚不得闲,千辛万苦保丰收,农大功绩留诗篇
The most important: the farmers write poems for the scientists to show there thanks
