1981-1982年,我们在烟草所内做了烤烟地面覆盖栽培试验.又在禹县,陕县、巩县、临颍县做了大面积示范.两年试验结果一致,增产增质,效果显著.覆盖比不覆盖单产提高32.4%,斤烟均价提高15.8%,亩产值多118.4元,提高53.4%,上中等烟比例提高20.8%,每亩用地膜8公斤,花费30.4元,净收入88元.(一)试验设计与经过试验地前茬为玉米,玉米收获后机耕深翻,栽烟前一个月撒施粗肥,浅耕细耙.黄沙壤土,PH值7.5,有机质含量1%.速效氮65PPm,速效磷20ppm,速效钾120
In 1981-1982, we experimented on the cultivation of flue-cured tobacco ground cover in the tobacco factory, and carried out large-scale demonstration in Yu County, Shanxian County, Gong County and Linying County. The results of the two years were consistent, and the yield was increased and the effect was remarkable. Covering an increase of 32.4% over non-covered yields and an average increase of 15.8% over mucking, the mu production value was 118.4 yuan more, an increase of 53.4%. The proportion of upper middle-grade tobacco was increased by 20.8%. 8 kilograms of film per mu was spent at 30.4 yuan and the net income was 88 yuan (I) Experimental design and experimenting The former crop is maize and the corn is plowed and deep plowed after harvesting. One month before planting tobacco, coarse fertilizer and shallow tillage rake are applied. Yellow sandy loam with PH value of 7.5 and organic matter content of 1% Nitrogen 65PPm, available phosphorus 20ppm, available potassium 120
