保水剂用量对豫西旱地土壤养分和烤烟质量的影响
Effects of super absorbent polymers’ dosages on soil nutrient and quality of flue-cured tobacco in Western Henan arid region
摘要
Abstract
In order to improve water shortage of tobacco field and unstable yield and quality of tobacco in the arid land of west Henan Province,four treatments of super absorbent polymers(SAPs)in the field experiments were carried out in Luoyang tobacco growing area.T1(CK)represented local conventional cultivation measures without SAP,T2 represented 15 kg·hm-2of SAPs,T3 represented 30 kg·hm-2of SAPs and T4 represented 45 kg·hm-2of SAPs.The influence of super absorbent polymers on soil moisture and nutrient,the growth of tobacco,chemical property and economic characters of flue-cured tobacco were studied.Results indicated that the T4 and T3 can improve the soil moisture content,alkali-hydrolyzable nitrogen content,available phosphorus content,available potassium content and organic matter content in each stage of the whole tobacco growing period than CK; Applica-tion the SAP can significantly increase the content of total sugar,reducing sugar,potassium,carotenoid catabolites,the products of browning reaction and neophytadiene of tobacco,decrease the nicotine,chlorine,aro-matic amino acid and cembratriendiol catabolites content.The ratio of sugar to nicotine and the ratio of potassium to chlorine had increased.The neutral aroma components of tobacco was coordinated,which improves the quality of to-bacco leaves.The tobacco yield from T4 and T3 treatments had significantly increased by 12.79％and 10.25％com-pared with CK,respectively.The production value of tobacco from T4,T3 and T2 treatments had significantly in-creased by 15.07％,15.25％and 4.51％.Under the condition of 30 kg·hm-2SAPs,not only available soil nutri-ents improved,but also the chemical components and economic benefit of flue-cured tobacco improved.关键词
