采薹次数对洱海流域菜-油两用油菜菜薹和菜籽产量、品质及综合效益的影响
Effects of plucking times on yield,quality,and comprehensive benefits of flowering stalk and rapeseed of oilseed-vegetable dual-purpose rape(Brassica napus)cultivated in Erhai Lake Basin
摘要
Abstract
To improve green high-value collaboration models in Erhai Lake Basin,Yunnan Province,optimal plucking frequency for oilseed-vegetable dual-purpose rape(Brassica napus L.)was detemined by using cultivar Yunyouza 15.Field experiments were conducted to investigate growth duration and agronomic traits of rape,and al-so comprehensive economic value of flowering stalk and grain yield under different plucking times(i.e.0,1,2 times,respectively).Moreover,nutritional quality changes of rapeseed after stalk harvesting were determined.Results showed that plucking times prolonged growth process,decreased plant height,decreased branching site and first ef-fective branches,but increased stem diameter and rebranches number,with increased effective branches and si-liques.Plucking times did not affect seeds per silique,individual plant productivity(seeds per plant)and 1000-seed weight.Compared with non-plucking,plucking once or twice did not significantly affect seed yield(the theoret-ical and actual yields were respectively 3836-3999 kg/hm2 and 3316-3717 kg/hm2);in the contrast,they significant-ly increased the yield of flowering stalk.Therefore,the benefit-cost ratio of Yunyouza 15 was respectively 0.48,1.02 and 1.55 when plucking 0,1 and 2 times.Correspondingly,its comprehensive economic value was achieved maximum with its figure of 86 369 yuan/hm2 when plucking twice,greater than that of plucking once(53 171 yuan/hm2)and non-plucking(23 324 yuan/hm2).In addition,an increasing plucking time did not significantly affect the seed quality as erucic acid content,glucosinolate and oleic acid contents.It significantly altered the contents of oil,protein and linolenic acid of rapeseed.In conclusion,plucking flowering stalk twice could produce the highest com-prehensive benefits when cultivating oilseed-vegetable dual-purpose rape in Erhai Lake Basin.关键词
