几年来,我们研制成几种花卉粒肥,经使用反映较好。为确定花卉粒肥的适宜配方和用法,我们用定期测盆土及淋溶液电导来控制施肥,经过20余种花卉的盆栽试验,证明是个简便有效的方法。 (一)方法:盆土电导测定:施粒肥于盆土,定期取样(除去残存粒肥),以5:1水土比振荡取滤液分析。淋溶液电导测定:盆下套不透水盆集淋液定期测定。供试粒肥由有机、无机养分及微量元素等配合,含N.P.K有效成份20～26％,压成9mm粒径片剂,分苗期(F221)中、后期(F311),冬季基肥(B411)等几种粒肥。用代表性园林培养土栽花,于不同季节进行试验。
In recent years, we developed several kinds of flower granule fertilizer, the use of reflected better. In order to determine the appropriate formula and usage of flower granule fertilizer, we control the fertilization by periodically measuring the conductivity of peat soil and leaching solution. After more than 20 kinds of flower pot experiments, it proved to be a simple and effective method. (A) Method: Pentu conductivity measurement: granulation fertilizers in the basin soil, regular sampling (remove residual granule), with 5: 1 ratio of water and soil vibration filtrate was analyzed. Leaching solution conductance determination: under the set of impervious basins set of leaching fluid regularly measured. The test granule is composed of organic and inorganic nutrients and trace elements, and contains 20-26% of NPK active ingredient and is compressed into 9mm grain size tablets, in the middle of F221, in the late stage (F311) and in winter base fertilizer (B411) Several kinds of grain fertilizer. Cultivation of soil with a representative garden flowers, tested in different seasons.
