Effect of reducing chemical fertilizer and applying microbial one on the growth and yield of Carthamus tinctorius L.under mulch drip irrigation
[目的]研究化肥减量配施微生物菌肥对膜下滴灌红花生长发育及产量的影响.[方法]2020～2021年在新疆塔城地区裕民县设置2 年定位施肥试验,采用裂区试验设计,设6 个处理:(1)对照CK:不施肥;(2)CF:复合肥20 kg/667m2;(3)OF:微生物菌肥20 kg/667m2;(4)CF+25M:化肥15 kg/667m2(化肥减量 25%)+微生物菌肥5 kg/667m2;(5)CF+37.5M:化肥 12.5 kg/667m2(化肥减量 37.5%)+微生物菌肥 7.5 kg/667m2;(6)CF+50M:化肥10 kg/667m2(化肥减量50%)+微生物菌肥10 kg/667m2.研究不同施肥处理对红花农艺性状、干物质积累与分配和产量形成的影响.[结果]处理CF+25M和CF+37.5M有利于红花的生长发育,可以显著增加红花株高、分枝数、叶片数和叶绿素含量等,并能促进红花干物质积累,调节干物质分配,协调改善红花产量构成因素,从而增加红花花丝和籽粒产量.其中以CF+37.5M处理下红花综合性状表现最优,其单株果球数、千粒重、花丝产量和籽粒产量分别比CF处理显著提高了 87.85%、12.29%、11.42%和15.78%,同时株高、根长和叶绿素含量亦均达到最高水平.[结论]化肥减量配施微生物菌肥CF+37.5M:化肥12.5 kg/667m2(化肥减量37.5%)+微生物菌肥7.5 kg/667m2 最优,能有效降低化肥施用量,促进红花生长发育,从而提高肥料利用率.
[Objective]To study the effect of chemical fertilizer reduction combined with microbial fertil-izer on the growth and development of Carthamus tinctorius L..[Methods]From 2020 to 2021,a two-year located fertilization experiment was arranged in Yumin County,Tacheng Prefecture,Xinjiang.The split plot experiment design was adopted,and six treatments were set up:(1)CK:no fertilization;(2)CF:compound fertilizer of 20 kg/667m2;(3)OF:microbial bacterial fertilizer of 20 kg/667m2;(4)CF+25M:chemical fertil-izer of 15 kg/667m2(chemical fertilizer reduction of 25%)+microbial bacterial fertilizer of 5 kg/667m2;(5)CF+37.5M:chemical fertilizer of 12.5 kg/667m2(chemical fertilizer decreased by 37.5%)+microbial bac-terial fertilizer of 7.5 kg/667m2;(6)CF+50M:chemical fertilizer of 10 kg/667m2(chemical fertilizer de-creased by50%)+microbial bacterial fertilizer of 10 kg/667m2.During the experiment,the effects of differ-ent fertilization treatments on the agronomic characters,dry matter accumulation and distribution,and yield formation of Carthamus tinctorius L.were studied.[Results]The results showed that CF+25M and CF+37.5M treatments were more conducive to the growth and development of Carthamus tinctorius L.than CF treatment,which could significantly increase the plant height,number of branches,number of leaves and chlorophyll content of Carthamus tinctorius L.,promote the accumulation of dry matter of Carthamus tinctorius L.,regulate the distribution of dry matter,coordinate and improve the yield components of Carthamus tinctori-us L.,thereby increasing the yield of Carthamus tinctorius L.filament and seed.Among them,the compre-hensive performance of Carthamus tinctorius L.under CF+37.5M treatment was the best.The number of fruit balls per plant,1,000 grain weight,filament yield and grain yield of Carthamus tinctorius L.under CF+37.5M treatment were significantly increased by 87.85%,12.29%,11.42%and 15.78%,respectively,compared with CF treatment.In addition,the plant height,root length and chlorophyll content of Carthamus tinctorius L.reached the highest level under CF+37.5M treatment.[Conclusion]Proper reduction of chemi-cal fertilizer and application of microbial fertilizer(37.5%reduction of chemical fertilizer,12.5 kg/667m2 of chemical fertilizer+7.5 kg/667m2 of microbial fertilizer)is an environmental protection fertilization scheme that can effectively reduce the application amount of chemical fertilizer.It can promote the growth and develop-ment of Carthamus tinctorius L.root system,improve the fertilizer utilization rate,so as to increase the dry matter accumulation of Carthamus tinctorius L.,coordinate the yield composition of Carthamus tinctorius L..
