我场自一九七五年以来对多功能的新型有机肥料——腐植酸类肥料(以下简称腐肥)在烟草上连续进行了四年的田间肥效试验,均获得显著的效果. 许昌烟区,历来多以饼肥作为烟田的主要细肥,近几年来由于饼肥缺乏,复合化肥也少,因之,氮素化肥已成为烟田的主要细肥,目前许昌烟叶品质显著下降,这也与氮素化肥有密切的关系.鉴于这种情况,为解决无饼肥也能生产好烟的问题,我场从一九七五年起就开展了腐肥的田间肥效试验,当年是以麻饼对比(即主要是以腐铵亩施150斤与麻饼100斤/亩对比),试验设计虽很简单,但结果已看出苗头,一九七六年又继续进行,原拟以腐植酸氮、砱、钾复合肥再与麻饼比较,但试制单位由于当时缺钾不得已只
Since 1975, our field has achieved remarkable results on four consecutive years of fertilizer experiments on tobacco, a new multi-functional organic fertilizer - humic acid fertilizer (hereinafter referred to as rotifer fertilizer) , Has always been to cake as the main fertilizer fine tobacco, in recent years due to the lack of cake, compound fertilizer is also less, therefore, nitrogen fertilizer has become the main fine tobacco, the current Xuchang tobacco significantly reduced quality, which is also In view of this situation, in order to solve the problem of producing good smoke without cake, my field experiment on the effect of rotting fertilizer was started in 1975, (That is, compared with 150 kg mu of gramineous ammonium and 100 kg / mu of hemp cake), the experimental design was very simple. However, the results showed signs of expansion and continued in 1976. The original plan was to use humic acid nitrogen,砱, potassium compost and then compared with the hemp, but the trial unit due to the lack of potassium last resort only
