我社种植甜菜已近十年,开始只种春菜,产量逐年提高。三、四年后,产量逐渐下降。随着种植时间的延长,春甜菜表现病虫害重、成本高、产量低,效益差,趋向绝路。经过试验示范和推广夏播,甜菜获得了新生。全社七四年种植着甜菜1100亩,平均亩产3533斤,七五年1400亩,平均亩产3750斤,七六年1100亩,平均亩产3959斤。一般丰产田亩产达6000～8000斤。前冢子头大队270亩甜菜,平均亩产8000斤,其中一亩八分高产田,亩产达11,000斤。由于产量高,收入大,社员都想多种,所以面积越来越大。此后,产量逐年下降,部分地块因病虫害减产 I plant sugar beet cultivation for nearly 10 years, beginning only spring vegetables, production increased year by year. Three or four years later, the output gradually decreased. With the extension of planting time, the performance of peanuts in spring beets is high, the cost is high, the yield is low, and the benefits are poor. After trial and demonstration and promotion of summer sowing, the beet was reborn. The whole community in 1974 cultivation of sugar beet 1100 mus, the average yield of 3533 kg, 1400 acres in 1975, the average yield of 3750 kg, 1100 acres in 1976, the average yield of 3959 pounds. Average yield per mu up to 6000 ~ 8000 kg. 270 mu of sugar beets of the former Muguizetou brigade had an average mu yield of 8,000 jin, of which 8 mu is a high yield field with an acreage of 11,000 kilograms. As a result of high output and large income, members want a variety of things, so the area is getting bigger and bigger. Since then, production declined year by year, some plots due to pests and diseases cut
