地方品种——“禾”的光温反应特性尚未见系统的报道。为了给高产栽培、引种、育种提供某些依据,我们对“禾”的这一特性作了一些初步研究。 水稻生育期的长短本质的差异在于品种的“两性一期”,我们的试验主要涉及这个问题。 一、试验方法及材料 采用人工遮光处理和田间分期播种相结合的办法,参照异地种植的抽穗情况,综合考虑“禾”的光、温反应特性。
Local varieties - “Wo” light-temperature response characteristics have not yet been systematically reported. In order to provide some basis for high-yielding cultivation, introduction and breeding, we made some preliminary studies on this characteristic of “Wo”. The nature of the difference between the length of rice growth period lies in the variety of “one of the two sexes,” our experiment is mainly involved in this issue. First, the test methods and materials Artificial shading treatment and sowing in the field by a combination of methods, reference to the heading of planting off-site situation, taking into account the “Wo” light and temperature response characteristics.
