Abstract:
Taking calcium sulfate as test materials,with garlic growth as research object,designs were set up on calcium sulfate (gypsum) for different fertilizer rate:75 kg/hm2,150 kg/hm2,225 kg/hm2 and 300 kg/hm2,with no calcium sulfate as control(CK),completely random block designs were applied on designs.The growth periods,garlic yield and weight of individual garlic bulb were measured,to study the application performance of calcium fertilizer in garlic cropland in calcareous soil.The results showed that the application of calcium sulfate fertilizer benefited garlic cultivation in many aspects:seedling stage,flowers phosphorus bud differentiation stage,stem elongation stage,and bulb hypertrophy stage were ahead of 0~2 days,maturation stage delayed 0~3 days,and resistance to disease and insects increased along with fertilizer rate,from infection to minor to resistant.Weight of individual bulb increased,compared with the control group,by 8.74%,13.29%,18.91% and 25.30% respectively,and the differences were significant;yield increased by 8.73%,13.27%,18.90%,25.29% respectively,and the differences were also significant.In conclusion,for garlic plantation in calcareous soil,application of calcium sulfate fertilizer could improve the performance of resistance to diseases and insects,and increase field production.
