茎瘤芥一次性施肥技术研究

Study on the One-time Fertilization Technology of Tumorous Stem Mustard

采用田间试验方法,研究了不同肥料不同施肥水平对茎瘤芥产量和经济效益的影响。结果表明:芭田复合肥料和沃夫特控释掺混肥两种肥料增产幅度较大。其中,芭田复合肥料平均产量2096.7 kg/667m2,比常规施肥增产7.0%;沃夫特控释掺混肥平均产量为2040.0 kg/667m2,比CK1增产4.1%。采用芭田复合肥料芭田复合肥料B2组合增产增收效果最好,A3B2组合效果其次;芭田复合肥料芭田复合肥料B2和沃夫特控释掺混肥B2组合每667m2茎瘤芥产量分别增加181.1kg、163.3kg,收入分别增加93.0元、35.3元。用芭田复合肥料、沃夫特控释掺混肥一次性施肥,可比常规施肥显著减少化肥施用量,其中芭田复合肥料总养分比常规施肥减少35.47%,纯N施用量减少57.77%,P_2O_5施用量减少17.5%;沃夫特控释掺混肥总养分比常规施肥减少36.9%,纯N施用量减少43.7%,P_2O_5施用量减少40.0%。采用一次性施肥方式,每667m2比常规施肥节省用工0.5个,节省人工成本30元。生产上可使用芭田复合肥(21-11-13)或沃夫特控释掺混肥(28-8-8)作为茎瘤芥一次性施肥品种,施肥时间为茎瘤芥定植后7d左右,肥料用量为45kg/667m2。

The effects of different fertilizers and different fertilization levels on the yield and economic benefit of tumorous stem mustard were studied by field experiment. The results showed that the yield of tumorous stem mustard was higher after treatment with Batian compound fertilizer and Volfertile controlled-release mixed fertilizer. Compared with traditional fertilization,the average yield of Batian compound was 2096. 7 kg/667 m2,the yield increased by 7. 0%; The average yield of Volfertile controlled-release mixed fertilizer was2040. 0 kg/667 m2,and the yield increased by 4. 1%. The Batian compound fertilizer at 75 kg/667 m2 group yield and income increased the most; Volfertile controlled-release mixed fertilizer B2 group followed; The yields of Batian compound fertilizer at 75 kg/667 m2 and Volfertile controlled-release mixed fertilizer at 75 kg/667 m2 were increased by 181. 1 kg,63. 3 kg respectively,and the income was increased by 93. 0 yuan,35. 3 Yuan respectively. Compared with conventional fertilization,the use of Batian compound fertilizer,Volfertile controlled-release mixed fertilizer as a one-time fertilizer varieties,can significantly reduce the amount of fertilizer application.Among them,Batian compound fertilzier total nutrient decreased by 35. 47%,pure N application decreased by 57. 77%,P_2O_5 application decreased by 17. 5%; Volfertile controlled-release mixed fertilizer total nutrient decreased by 36. 9%,pure N application decreased by 43. 7%,P_2O_5 application decreased by 40. 0 %. Compared with conventional fertilization,one-time fertilization method could save 0. 5 d per 667 m2; Batian Compound Fertilizer（ 21-11-13） or Volfertile controlled-release mixed fertilizer（ 28-8-8）could be used as a one-time fertilization of the stem tumor,and the fertilization time was 7 days after the plantation of the stem,and the fertilizer application rate of 45 kg/667 m2.
