近年来,我们进行了烟田地套种甘薯试验,获得烟叶亩产176公斤,亩产值1659.75元,其中上等烟36.5公斤,占20.7％;上中等烟141.5公斤,占80.4％。甘薯亩产达2870公斤,按市场价每公斤0.6元,亩产值达1722元。烟叶、甘薯合计亩产值达3381.75元。其主要栽培技术如下: 一、冬耕耙糖、起垄施肥 烟叶与甘薯套种,前期以烟叶为主,必须立足抗旱、蓄水、保墒,做到秋雨春用。烟田冬前要深耕耙糖,每亩施入农家肥2000～2500公斤、饼
In recent years, we conducted a trial of sweet potato interplant with sweet potato to obtain 176 kg of mu per mu, with an output value of 1659.75 yuan per mu, of which 36.5 kg was the finest smoke, accounting for 20.7%. The upper middle class was 141.5 kg, accounting for 80.4% of the total. Sweet potato yields up to 2870 kilograms, according to the market price of 0.6 yuan per kilogram, the output value of 1722 yuan per mu. Tobacco, sweet potato total output value of 3381.75 yuan. The main cultivation techniques are as follows: First, winter harvest rake sugar, Ridge ridge tobacco and sweet potato interplanting, pre-tobacco, must be based on drought, water, soil moisture, so autumn rain. Tobacco fields to cultivate harrow sugar before winter, per mu applied to manure 2000 ~ 2500 kg, cake
