植物动力2003(简称PP2003),是德国研制的新型螯合植物营养液肥,含有140多种活性有机物和无机物以及微量元素铜、锰、锌等。为探明它对切花月季的增产效应,我们于1997年12月至1998年1月进行了田间喷施试验,证实冬施PP2003确能显著提高产量。现将结果介绍如下: 一、试验方法: 供试验的PP2003,系德国圣托罗公司产品,试验材料是切花月季‘大丰收’。将7.5×40米塑料大棚内的植株纵向分成两半,一半(550株)喷施PP2003 1000倍液,另一半不喷。喷施时间为1997年12月
Plant Dynamics 2003 (referred to as PP2003), is a new type of chelated plant nutrition liquid fertilizer developed in Germany, containing more than 140 kinds of active organic and inorganic substances and trace elements such as copper, manganese and zinc. To test its effects on cut rose production, we carried out a field spraying experiment from December 1997 to January 1998, confirming that winter application of PP2003 can significantly improve the yield. Now the results are described below: First, the test method: for the test PP2003, the Department of Germany’s Santoro products, test materials are cut roses ’bumper harvest’. Will 7.5 × 40 m plastic greenhouse vertical divided into two halves, half (550) spraying PP2003 1000 times the other half is not sprayed. Spraying time for December 1997
