| 摘 要： | 该文以多年生芦笋"井冈红"为试材,研究了不同氮肥用量对绿芦笋产量及采摘期的影响。结果表明,施纯氮在0~15.4kg/667m2范围内,随着氮肥用量的增加绿芦笋产量呈先升高后降低的趋势,其中产量在纯氮用量为11.93kg/667m2时最高,最高产量为1 321.14kg/667m2。在芦笋采摘过程中,3月下旬至4月中上旬采摘量最大。

| Abstract: | In this experiment,perennial Asparagus officinalis“JingGang Red”as text material to study the effects of different amount of nitrogen fertilizer on yield and picking period of green asparagus.The results showed that ,the yield of green asparagus increased first and then decreased with the increase of amount of the nitrogen fertilizer dur?ing the harvesting time when the amount of nitrogen fertilizer is within N 0~15.4kg/667m2.Applied pure N 11.93kg/667m2 to the perennial asparagus“JingGang Red“the effect is remarkable,the highest yield is 1 321.14kg/667m2.In the process of asparagus harvest,the maximum amount of picking is from late March to early April. |
