绿肥作物的应用施绿肥就是种植生长迅速、有汁液丰富的上部的绿色植物,并应趁其多汁液,碳氮比低时将其翻入土内。老熟的植物残体碳氮比高;碳50%,氮1%以下。直到碳氮比降到15:1或10:1范围内,土壤中的氮素才被土壤微生物应用。通常,施点氮肥促进绿肥作物分解,并保持碳氮比适度,对苗木是有利的。趁绿肥作物未老熟时翻耕的另一理由是防止形成种子,因为这些不需要的绿肥作物种子,在未熏蒸的苗床上会发芽。
Application of Green Manure Crops Green manure is planted with green plants that grow rapidly and have abundant juice. They should be turned into the soil while their juicy liquid and carbon-nitrogen ratio are low. The old plant residue carbon and nitrogen than the high; 50% of carbon, nitrogen below 1%. Until the C / N ratio drops to 15: 1 or 10: 1, nitrogen in the soil is applied by soil microorganisms. In general, applying nitrogen fertilizer to promote the decomposition of green manure crops, and to maintain moderate carbon and nitrogen ratio, is favorable for seedlings. Another reason to turn tillage while green manures are not ripe is to prevent seeds from forming because these unwanted green manure seeds germinate on unfused seedbed.
