为了测定施入土壤中的有机物对日本夏橙实生苗生长的影响。处理施用各种有机肥,包括禽粪,木屑堆肥、干稻草和枯桔枝,浸水后再干的稻草和枯桔枝。结果表明,除施再干枯桔枝处理外,土壤空气中的乙烯含量因施有机物而急剧增加,并强烈地抑制新梢的伸长,而当土壤空气中乙烯浓度降低时,茎的伸长又得到了某种程度的恢复。施再干枯桔枝处理,其土壤空气中的乙烯浓度只有0.65ppm甚至更低,新梢的伸长与对照几乎一样。在本试验中,对照的O_2和CO_2浓度分别是20～21％和0.7～1.3％,而处理的
To determine the effect of organic matter applied to the soil on the growth of Japanese summer orange seedlings. Disposal Various organic fertilizers, including poultry manure, sawdust compost, dried straw and dried orange, dried straw and dried oranges after soaking. The results showed that the content of ethylene in soil air increased sharply due to the application of organic matter, and the elongation of shoots was strongly inhibited, except for the application of dry orange shoots. When the ethylene concentration in soil air decreased, the elongation of stems Got some degree of recovery. Shi Zaizhu dry branches treatment, the soil air of ethylene concentration of only 0.65ppm or less, the elongation of the shoots and control almost the same. In this experiment, the control O 2 and CO 2 concentrations were 20-21% and 0.7-1.3%, respectively, while the treated
