| 摘 要： | 在盆栽条件下，采用不同土壤水分的处理，从齐穗期开始对基部节间伤流强度与穗颈节间伤流强度进行测定。结果表明，基部节间与穗颈节间的伤流强度差异显著，但它们在不同时期的变化趋势却大体相同。它们之间的差异说明穗颈节间的伤流强度不但与根系活力有关，可能与叶片、茎鞘及库容活性也有密切联系。土壤含水量达到100%时有利于水稻的中后期生长。

| Abstract: | Under different soil treatments of moisture, the pot experiments were carried out to research the bleeding intensity of base department to the spike neck. Results indicate: the bleeding quantity of base department and the spike neck has prominent difference, but their variation tendency in different periods is about the same. Difference of them prove flow intensity of spike neck not only relate to roots vigor, may have close ties with the leaf, stem sheath and activity of capacity of reservoir. The water content of soil up to 100% is favorable to growth of rice. |
