How valuable is drip irrigation technology in Israel?
2/kloc-0 At the beginning of the century, where was the most developed agricultural technology area in the world? Report, desert agriculture in Israel. Sit down. Farms are built in the desert, which can measure soil moisture, supplement irrigation, adjust growth and topdressing in an instant. It is a hero in all countries, but it is not suitable for China, because it cannot solve the employment problem of a large number of low-end laborers. Drip irrigation saves water on the one hand, but it may be more important to save labor in China. Up to now, about 270 million migrant workers in China have gone out to work in cities and are no longer engaged in agriculture. In 20 15, the total number of migrant workers in China was 277.47 million, an increase of 1.3% over the previous year. Among them, 6.5438+0.6884 million farmers went out, an increase of 0.4%; Local migrant workers 10863 million, an increase of 2.7%. And what is the rural population? According to the data released by the National Bureau of Statistics in 654381October 20th, the total population of Chinese mainland was about 137 billion at the end of 20 14, an increase of 7 10 million. ..... In terms of age composition, the working-age population of 16 to 60 years old (excluding 60 years old) is 915.83 million, a decrease of 37 10000 from the end of last year, accounting for 67.0% of the total population; The population aged 60 and over is 212.42 million, accounting for 15.5% of the total population, and the population aged 65 and over is137.55 million, accounting for 10. 1% of the total population. From the perspective of urban and rural structure, the urban resident population was 7.491.6000, an increase of1.80500 over the end of last year, while the rural resident population was 61.86600, a decrease of1.9500, accounting for 54.77% of the total population. We can see a general trend that the rural labor force is rapidly decreasing. This is a good thing, because it means that more and more people enter cities and enjoy the life of modern industrial society. But this trend is a devastating blow to intensive traditional agriculture. According to my observation, the rural labor force around Wuhan is mainly the elderly over 50 years old and has not received much education. These people can neither do heavy manual labor to intensive cultivation, nor accept modern agricultural technology to engage in modern agriculture, nor have the skills born in industrial society or pension insurance. Reflected in agricultural production, that is, throwing seedlings, direct seeding, ratooning rice and a series of simple cultivation have been widely promoted. Although drip irrigation can comprehensively manage water, fertilizer and medicine, it can greatly save labor. But these things are too difficult for these people. Of Chinese mainland's 3/kloc-0 provinces, autonomous regions, municipalities directly under the central government and servicemen, the population with college education or above is 1 19636790; The population with high school (including technical secondary school) education is/kloc-0 187985979;; Junior high school education population 519656445; The population with primary school education is 358,764,003 (the above-mentioned population with various education levels includes graduates, dropouts and students of various schools). As for dry farming with plastic film mulching, that is another problem. It takes too much manpower to do this thing by manpower, but mechanization is a problem of multiple processes. However, the broken farmland in southern China is not suitable for mechanization. I used to grow peanuts in Hongan, Huanggang, and I have a deep understanding in this respect.
