烤煙豐產(chǎn)溝模式化栽培抗旱技術(shù)研究

Study on Drought Resistance Technology of High Yield Ditch for Pattern Cultivation of Flue-cured Tobacco

摘要: 在烤煙生產(chǎn)中應(yīng)用豐產(chǎn)溝模式化栽培技術(shù),，可最大限度地?cái)r蓄天然降水，變無(wú)效雨為有效雨,，有效調(diào)節(jié)天然降水的不足和季節(jié)降水不均的供需矛盾,，從而為煙株生長(zhǎng)創(chuàng)造出優(yōu)越的局部環(huán)境，達(dá)到穩(wěn)產(chǎn),、高產(chǎn)和提高煙葉品質(zhì)的目的,。豐產(chǎn)溝處理的土壤含水量與弓背壟處理相比含水量提高25%～35%，根系深扎土層至120 cm,。與槽型垅,、弓背壟處理相比,，產(chǎn)量分別增加480 kg/hm2和1425 kg/hm2,豐產(chǎn)溝模式化栽培技術(shù)具有蓄水抗旱和增產(chǎn)提質(zhì)的作用，效果優(yōu)于槽型壟,，更優(yōu)于弓背壟,。

Abstract: High yield ditch applied to flue-cured tobacco production can largely hold up rainwater, change useless rainwater into useful water, and effectively solve problem of volume and distribution of precipitation, which can provide great local environment for tobacco growth, so that stable and high yield can be achieved, and tobacco leaf quality can be improved. Soil moisture with the ditch was 25% to 35% higher than with arch ridge, and the yield with the ditch was 1 425 kg/hm2 higher than with arch ridge, and kg/hm2 480 higher than with gutter ridge. The ditch can hold soil water，increase yield,，improve leaf quality, and was the best among the three treatments.
