硅钙素生物有机肥在加工番茄上的应用效果!

为提高加工番茄产量,改善其品质,通过田间试验和室内分析,研究了银北盐化灌淤土施用硅钙素有机肥后,对土壤理化性质、露地番茄生长发育、产量、品质及经济效益的影响。结果表明:施用硅钙肥3 000kg·hm-2掺施50%化肥与常规施肥相比可有效促进露地番茄生长发育,增加叶片叶绿素合成,提高叶片胞间CO2浓度、蒸腾速率及气孔导度,增长率依次为29.88%、6.04%、9.48%和25.00%,有效促进了番茄生理代谢;降低土壤全盐28.81%,有利于抑制土壤盐化危害;降低土壤容重6.57%;番茄可溶性固形物增长5.59%;含糖量增加39.01%,糖酸比增加32.50%,产量增长11.96%,可增产提质,肥效显著。单独施用3 000kg·hm-2硅钙肥与常规施肥相比,可降低土壤全盐36.02%,有利于盐碱地脱盐抑盐;与种植前相比,土壤速效磷增加土壤速效磷增加58.61%、速效钾增加44.55%,表明硅钙肥具有显著的解磷释钾作用。

Effect of Calcium Silicon Fertilizer on Processed Tomatoes

In order to improve the yield and quality of processed tomato,through field and indoor experiments,the effect of irrigated saline soil in northern Yinchuan area after applying silicon osteocalcin organic fertilizer on soil physical and chemical properties was studied,the effect on tomato growth,development and yield,quality and economic benefit was analyzed.The results showed that the application of calcium silicon fertilizer3 000kg·hm^-2 mixed 50% chemical fertilizer compared than covention fertilizing could effectively promote the tomato growth and development,increased chlorophyll synthesis,improved the blade intercellular CO2 concentration,transpiration rate and stomatal conductance,growth were 29.88%,6.04%,9.48% and 25.00% respectively,while it promoted physiological metabolism,reduced 28.81% soil total salt,and was helpful for inhibiting soil evapo-salinization hazards.In addition,it reduced soil bulk density by 6.57%;tomatoes total soluble solids grew 5.59%;the sugar content increased by 39.01%,sugar-acid increased by 32.50%,production yield increased by 11.96%,the application of calcium silicon fertilizer could improve the quality and yield,and the effect was significant.Only calcium silicon fertilizer than coventional fertilizing,could reduce soil total salt by 36.02%,and was helpful for desalination and restraining salt of saline alkali soil;soil available phosphorus and available potassium increased by 58.61%and 44.55%than before planting,showed that the calcium silicon fertilizer has significant effect for solubilizing phosphate and releasing potassium.
