我省甜菊定植期一般在6月上中旬。为充分利用定植前这段空闲时间做到一地两收,提高单位面积产量和效益,我们在1987年做了前茬种豌豆、下茬栽甜菊的试验。前茬豌豆亩产416.9公斤,收入250.14元;下茬甜菊亩产干叶140.17公斤,收入616.31元,两茬共收入866.45元,扣出生产成本,亩纯收入573.33元。具体做法是:早春整地,每亩施农家肥3000公斤,作成50厘米行距的垄,4月11日播种豌豆,每亩播种量11公斤。出苗后锄两遍,趟两遍。开花前后若天旱,浇1—2遍水。6月18日收获豌豆。
Stevia planting season in our province generally in mid-June. In order to make full use of this free time before planting to achieve one by one, to improve production and efficiency per unit area, we did in 1987, the first crop of peas, the next plant stevia trial. The yield of peas in the previous crop was 416.9 kg and the income was 250.14 yuan. The yield of sweet bean under the dry grapes was 140.17 kg per mu, with a revenue of 616.31 yuan. The total revenue of the two crops was 866.45 yuan, with the deduction of production cost and the net income of 573.33 yuan per mu. The specific approach is: early spring soil preparation, farmland fertilizer 3000 kg per acre, made of 50 cm row spacing of the ridge, April 11 sowing peas, seeding per acre 11 kg. Hoe twice after emergence, trip twice. If drought before and after flowering, pour 1-2 times water. June 18 Harvest peas.
