烤煙地瓜間作模式研究

On the Intercrop Mode for Flue-cured Tobacco and Sweet Potato

摘要: 針對臨朐縣人多地少，糧煙爭地矛盾突出,，烤煙種植調(diào)茬難度大,，煙田連作地塊較多，土壤板結(jié)嚴(yán)重,，病蟲害發(fā)生逐年加重等問題,，在多年試驗示范的基礎(chǔ)上，分析了烤煙,、地瓜間作的優(yōu)勢,、種植模式、經(jīng)濟效益及其推廣的關(guān)鍵技術(shù)措施,。結(jié)果表明,，烤煙、地瓜間作既可增加單位面積效益,，又可增加烤煙種植面積,，是在大面積調(diào)整茬口困難的情況下，可采取的一種有效的“微調(diào)”模式,。

Abstract: High population with limited land, tobacco competing land with grain crop, difficult in adjusting tobacco planting system, continuous tobacco planting, severe soil compaction, increasing diseases and insects, all of these problems influenced tobacco production in Linqu county. Based on long-term experiments and demonstration, the advantage of flue-cured tobacco and sweet potato intercopping system, planting mode, economic profit, and the key measures for extension were analyzed. The results indicated that flue-cured tobacco and sweet potato inter-cropping system could increase profit per unit land area and tobacco planting area. The system is an effective adjustment measure under the condition of difficult in adjusting rotation in large scale.
