近二年来,我省小麦生产面积迅猛发展,解决下茬是当务之急。为提高复种指数,充分利用地力和光能,增加单位面积产量和效益,我们搞了麦田复栽甜菊试验。前茬小麦45平方,米收25.12公斤,折亩产372公斤,纯收入335元;下茬20平方米甜菊收干叶1.95公斤,折亩产65公斤,纯收入225元。两茬合计每亩纯收入560元。
The past two years, the rapid development of wheat production in our province, to solve the next crop is imperative. In order to improve the multiple cropping index, make full use of geo-energy and light energy, and increase yield and benefit per unit area, we conducted a trial of planting sweet stevia in the field. 45 square meters of former crop wheat, rice harvest 25.12 kilograms, fold per-mu produce 372 kilograms, net income 335 yuan; next 20 square meters of stevia dried leaves 1.95 kilograms, yield 65 kg per mu, net income of 225 yuan. The total revenue of 560 yuan per mu for the two plots.
