春播架豆以嫩豆荚作菜用,营养价值高,很受市场欢迎。我区架豆栽培历史较久,但因其产量低,收入少,栽培面积较少。近三、四年由于推广了塑料薄膜地面覆盖,使其产量、产值大幅度上升。据我所1981—1983年三年试验120.1亩,平均每亩增产1111.4斤,增值205.07元。随着栽培技术不断改进,亩产值大幅度上升。1979—1980年地膜覆盖较未覆盖的每亩增收136.69元,1983年每亩增加273.44元。在地膜架豆增产增收的情况下,种植面积也在增加。1972—1979年八年平均每年种植2001.3亩,1980—1983年四年每年平均种植
Spring seeding beans to beans for cooking vegetables, high nutritional value, very popular with the market. I District Bean cultivation frame longer history, but because of its low yield, low income, less cultivated area. Nearly three or four years due to the promotion of plastic film ground cover, so that its output, output increased significantly. According to my 1981-1983 three years trial of 120.1 acres, an average yield of 1111.4 kg per mu, added value of 205.07 yuan. With the continuous improvement of cultivation techniques, the output value of mu has risen sharply. From 1979 to 1980, the film mulching increased by 136.69 yuan per acre than that of the mulch without mulching and by 1983 increased by 273.44 yuan per mu. In the case of plastic shelves beans yield increase, the acreage is also increasing. The average annual planting is 2001.3 mu per year for eight years from 1972 to 1979 and the average annual planting for four years from 1980 to 1983
