1962 In the winter, Jiao came to Lankao, and there was a serious famine in Lankao. In order to gain experience in the "three evils" struggle, Comrade Jiao personally led the cadres and the masses to carry out experiments of turning silt to suppress sand, turning silt to suppress alkali and sealing sand dunes on a small scale. Then, spread out from point to area, sum up the specific strategies to control the three pests, and explore the method of planting paulownia in a large area.
Expanding data and focusing on the three evils in the rectification movement
1, sand control
There is no forest in the sandy area, and there is land that does not support people. This is the basic situation; Where there is a forest, there is food, and if there is no forest, there will be hunger. This is the importance; Promoting agriculture by forest, supporting forest by agriculture, relying on agriculture and forestry, and close cooperation are the principles; Afforestation and sand prevention, a century-long plan, planting grass to seal sand, was effective in that year, silt turned over and sand pressed, and it was immediate, and the effect was good. This is the way.
2. Water control
Lankao has complex terrain, connected slopes and depressions, and disordered water system, which is an objective situation; It is a policy of drainage, irrigation, stagnation, waterlogging and reform. Give up less and save more, give up bad and save well, fully negotiate, benefit each other, take care of the upstream and downstream, and don't be a scourge. This is the policy; Observation in summer and autumn, dry treatment in winter and spring, re-observation and re-treatment, and combination of observation and treatment are the methods.
Step 3 treat alkali
Distinguishing seriousness from discrimination is a policy; Turning silt to suppress alkali, ditching to spray alkali, ridging to avoid alkali, planting in Taiwan Province and introducing alkali-tolerant crops are the methods.
