应用不同高效液肥在红星苹果树上喷施的田间试验结果表明：在红星苹果花后、幼果膨大期、果实膨大后期分３ 次喷施不同浓度的植物动力２００３、万德福３号、惠满丰、爱多收、绿风９５ 高效液肥，不但能促进果树营养生长、提高产量，而且可以改善果品品质、提高商品性，经济效益显著。其中以惠满丰３００ 倍液的效果最好，喷施后比对照增产１８．９９％ ，可溶性固形物增加２．９ 个百分点，果实硬度增加１．３２ ｋｇ／ｃｍ ２，特级和一级果率分别提高１４．０ 个百分点和１１．８ 个百分点，新增纯收益为１１ ３６２．８５元／ｈｍ ２。其次为万德福３ 号３００ 倍液，比对照增产１５．９４％ ，特级果率和一级果率分别比对照增加１３．３ 个百分点和９．３８ 个百分点，新增纯收益９ ２８５．７７ 元／ｈｍ ２。这两种液肥可在生产中推广应用。
Application of different high-efficiency liquid fertilizer sprayed apple trees in the Red Star Field experiments showed that: Red Apple flower, young fruit enlargement, fruit enlargement after spraying three different concentrations of plant dynamics in 2003, Wonderful No. 3, Hui Manfeng, love more income, green wind 95 efficient liquid fertilizer, not only can promote fruit tree vegetative growth, increase yield, but also can improve the quality of fruit, improve the product, significant economic benefits. Among them, 300% of FENGMENGFENG had the best effect. After spraying, it increased yield by 18.99%, soluble solids increased by 2.9%, fruit firmness increased by 1.32 kg / cm 2, The rates increased by 14.0 percentage points and 11.8 percentage points respectively, with a net income of 11 362.85 yuan / hm 2 added. Followed by Wandefu No. 3 300 times, 15.94% more yield than the control. The special fruit rate and the first fruit rate increased by 13.3 percentage points and 9.38 percentage points respectively compared with the control, with a net gain of 9 285. 77 yuan / hm 2. These two kinds of liquid fertilizer can be used in the promotion of production.
