Crops such as mulberry, fruit and tea are also suitable for development.
Before the founding of the People's Republic of China, most of the land was occupied by a few landlords and rich peasants, the poor peasants rented out their business, the landlords exploited them wantonly, the peasants had a hard life and agricultural production developed slowly. After the founding of People's Republic of China (PRC), the agricultural production in Yi 'an District has experienced many twists and turns, but it has made great progress.
From 65438 to 0949, the total agricultural output value of Yi 'an District (Tongling County) was15120,000 yuan (excluding forestry output value). The same below), in which the output value of agriculture, animal husbandry, sideline and fishery accounted for 72. 1%, 14.4%, 3.6% and 9.9% respectively. From 1950 and 10 to 195 1, 1 1, land reform was carried out to realize farmers' land ownership. Farmers engaged in agriculture with unprecedented enthusiasm, and the county government gave timely and vigorous support, and the agricultural landscape changed rapidly. The total agricultural output value of 1952 is 0.4 times that of 1949. After the land reform, the movement of mutual assistance and cooperation was launched, and the socialist transformation of agriculture was basically completed by 1956. In the meantime, farmers were also mobilized to build rivers and dams, and 1955 began the reform of farming system from single season to double season. From 65438 to 0957, the total agricultural output value increased to 49.36 million yuan. 1958 set off the people's commune movement.
In recent three years, due to the influence of "one big and two big" system, "blind command" administration, "high index" production and "big call" work, agricultural production has suffered serious setbacks. 1962, the total agricultural output value dropped to 31420,000 yuan. At the beginning of the year, the agricultural economy took a turn for the better by adjusting the relations of production and implementing the "three-level team as the foundation". 1965, the total agricultural output value increased to 4665438+ ten thousand yuan.
1966 to 1978 to carry out the "Agricultural Dazhai" activity. Build water conservancy projects, expand the planting of green manure and double-cropping rice, popularize new varieties, and realize "changing tall stalks into short stalks" of rice. Agricultural production conditions have been improved and the output of major crops such as grain and cotton has increased. However, due to the "Left" interference during the "Cultural Revolution", the one-sided emphasis on "taking grain as the key link" cut off the capitalist tail everywhere, restricted the development of household sideline products such as planting, feeding and processing, destroyed Sang Ma and other food crops, and the internal structure of agriculture was seriously unbalanced; Blindly reclaiming land from lakes, destroying forests and reclaiming land, the ecological environment is deteriorating. In addition, the egalitarian trend of thought of "doing more and doing less, doing and not doing the same" is rampant. As a result, the increase in production does not increase, and the income of farmers increases very little. The total agricultural output value of 1978 is only 47.42 million yuan. Among them, the output value of agriculture, animal husbandry, by-products and fishery accounted for 84. 1%,1.1%,2.9% and 1.9% respectively.

Vigorously promote advanced agricultural practical technologies such as hybrid breeding, plastic film mulching, model cultivation, formula fertilization, integrated pest control, and "three modernizations" (improved breeding of boars, localization of sows, and hybrid fattening of pigs), and successively implement comprehensive agricultural development projects such as transformation of low-yield fields and development of tons of grain fields. Agriculture, animal husbandry, by-products and fishing have developed in an all-round way, and the rural economy is unprecedentedly active. The total agricultural output value in 1990 reached 91050,000 yuan, 5.02 times higher than that in 1949, of which the output value of agriculture, animal husbandry, sideline and fishery accounted for 67.4%, 13.3% and 15.2% respectively. Compared with 1949, the output of main agricultural products increased by 2.54 times for grain, 56.2 times for cotton, 5.4 times for oilseeds, 2 times for cortex moutan, 0 times for silkworm cocoon, 0.03 times for hemp and 7.5 times for hemp.
