基于全程营养解决方案防治大蒜连作障碍问题的研究

采用大田试验方法，研究全程营养解决方案对大蒜长势、根系数量、感病率、抽薹率、倒伏率、蒜薹和蒜头产量以及经济效益的影响。结果表明：与2 种习惯施肥相比，全程营养解决方案明显提高了返青期和蒜薹伸长期大蒜的株高、茎粗、叶长和叶宽，显著增加了大蒜根系数量；蒜薹抽薹率显著提高了23～26 个百分点；倒伏率显著降低了30 个百分点；叶枯病和根腐病的发病率均显著降低。全程营养解决方案蒜薹和蒜头产量分别为192 kg·（667 m²）^-1 和1 537 kg·（667m²）^-1 ，每667 m² 净收入增加495～581 元。表明全程营养解决方案可以促进大蒜生长，减少病害发生，实现增产增收，适宜在山东金乡地区推广。

Studies on Controlling Garlic Continuous Cropping Obstacles Based on Whole-Process Nutrition Solution

Field experiments were conducted to study the effects of garlic whole-process nutrition solutionon garlic growth，root number，disease index，bolting rate，lodging rate，yield of garlic stem and garlic head，and economic effectiveness．The results showed that compared with 2 idiomatic fertilization methods，the wholeprocessnutrition solution increased the number of roots significantly，improved the plant height，stem diameter，leaf length and width of garlic in green and extension periods．The garlic bolting rate was significantly increasedby 23-26 percentage points．The lodging rate decreased by 30 percentage points．The disease index of leafblight and root rot was significantly reduced．The production of garlic stem and garlic head by whole-processnutrition solution were 2.88 t·hm^-2 and 23.06 t·hm^-2，respectively．The net revenue increased by 7 428-8 724 yuan·hm^-2，indicating the whole-process nutrition solution can promote garlic growth，reduce diseaseoccurrence，increase yield and income，and is suitable to be popularized in Jinxiang region．
