摘要:
以穗重型品种东农423和穗数型品系东农03-44为试验材料，于2008~2009年研究了超稀植栽培对水稻根系活力、根系POD、伤流液强度等变化规律的影响。结果表明：超稀植栽培条件下，根系健壮，衰老缓慢。较常规栽培根系干重和体积明显增加，上层根系分布较多。整个生育期内根系活力较高，齐穗后根系的伤流液强度和POD活性也明显高于常规栽培，且下降缓慢。
Abstract:
Variation regulation of growth dynamics, root activity, POD content of root, flux activity of root system, dry matter accumulation, nitrogen content, yield and quality performance under super-sparse cultivation technique were studied with Dongnong 03-44(panicle number type) and Dongnong 423(panicle weight type) from 2008 to 2009. The results were as follows:Under super-sparse cultivation conditions, rice root system was strong. Dry weight of root obvious promoted, root system that distributed in top soil layer was more. Root activity was still higher in the whole stage, bleeding of root system and POD activity after heading were higher than those of traditional cultivation.
