摘要
利用鸡粪为主体原料配以Ｎ、Ｐ、Ｋ化学肥料和硼、锌、锰等微量元素制成便于贮藏、运输和使用的有机－无机颗粒肥。以黄瓜、甘蓝、西红柿和花椰菜对５种配方进行选择试验，结果确定添加硼元素的配方２有机－无机颗粒肥为蔬菜作物的最佳配方，该有机－无机颗粒肥配方对秋甘蓝、秋黄瓜和冬瓜进行合理用量试验，结果表明，在常规习惯施肥基础上，每公顷施用３３７．５ｋｇ有机－无机颗粒肥为蔬菜作物的经济合理用量，对蔬菜增产起主导作用的因素是其中添加的微量元素，尤其是硼元素。这与菜区土壤微素调查有效硼含量偏低及施用硼肥对蔬菜有显著增产作用的结论是一致的。
Organic-inorganic granular fertilizer made of chicken manure powder plus N,P, K chemical fertilizers and microelements B,Zn, Mn, et al. was convenient for storage,transport and application. Experiments on 5 formulas of organic-inorganic granular fertilizer for 4 vegetable species were carried out. The result showed that the formula 2 in which B was included should be the optimum formula for the vegetable growth. The fertilizer formula 2 was then applied to autumn cabbage, autumn cucumber and white gourd in application amount experiments. The results showed that 337. 5 kg/hm2 was the rational application amount of organic-inorganic granular fertilizer for the vegetable growth among the application amounts tested(0,112. 5, 225,337. 5, 450 kg/hm2). This study indicated that some microelements,especially B,included in the organic-inorganic granular fertilizer were the major factors in the increase of vegetable yield. This correspond well to the results obtained from the soil microelements investigation in some vegetable areas.
