腐植酸膏体冲施肥不同施用次数对豇豆产量及下茬草莓后效作用试验研究

Effect of Different Application Times of Humic Acids Fertilizer on Yield of Cowpea and Its Residual Effect on the Following Strawberry

2005年5～7月进行了腐植酸膏体冲施肥在豇豆上适宜施用时间和施用次数对比试验。结果表明,施用过普天同乐膏体冲施肥,对当季作物增产作用显著,在豇豆上施用3次,每10d冲施一次,每次每667m^2施10kg为适宜施用次数和施肥量。2005年9月至2006年5月,上茬豇豆试验结束后,进行了膏体冲施肥对草莓后效作用试验。结果表明,对下茬草莓有明显后效作用,在试验条件下比对照增产10.91%～19.59%,其中667m^2冲施2次,半个月冲施1次,每次15kg,比对照增产19.59%,达1%显著水平。两茬作物总增产增收以处理3最高,共增产44.98%。

From May to July 2005, the comparative experiment of the different application times of humic acid paste irrigation fertilizer on cowpea growth was arranged. The results showed that applied humic acid paste irrigation fertilizer, the effect of increasing yield was significant on cowpea. Apply 3 times, irrigate 1 time for each 10 days, every time applied 10kg/mu on cowpea. From September 2005 to May 2006, at the end of the last crop cowpea, the experiment of different application times aftereffect function of humic acid paste irrigation fertilizer on strawberry growth. The results showed that the aftereffect function was significant. Could increase field by 10. 91%-19. 59% compared with the check in the experiment condition, in treatment applied 2 times, and irrigate 1 time for half month, 15kg/mu for 1 time compared with the check, could increased yield by 19. 59%, the aftereffect function was very significant, up to 1% remarkable standard. The third treatment is the highest about the total of increased yield and income in the two crops, increase total 44. 98%.
