摘要:

为探明磷肥含量、土壤类型对水稻秧苗素质、根系形态及养分吸收的影响,以中晚熟品种‘辽粳401’为试验材料,选用壤质土、黏质土和砂质土3种土壤类型,采用裂区试验方法研究6种磷肥与土壤组合对水稻秧苗素质的影响。结果表明:低磷黏土与高磷黏土培育的水稻秧苗素质最好,根系形态最佳,更有利于秧苗的生长。磷肥施入量2.5 g/盘能够满足水稻秧苗对磷肥的吸收,说明适量的磷肥有助于培育健壮的秧苗。

关键词: 磷肥, 土壤, 水稻, 秧苗素质, ‘辽粳401’

Abstract:

To find out the effects of phosphorus fertilizer content and soil type on rice seedling quality, root morphology and nutrient uptake, taking the mid-late maturing variety ‘Liaojing 401’ as the test material, we chose 3 soil types: loamy soil, clay soil and sandy soil, and studied the effects of 6 phosphorus fertilizer and soil type combinations on rice seedling quality by using the method of split block experiment. The results showed that: the rice seedlings cultivated by low-phosphorus clay and high-phosphorus clay had the best quality and root morphology, which was more conducive to the growth of seedlings; the phosphorus fertilizer amount of 2.5 g/pot could meet the rice absorption of phosphorus fertilizer, indicating that the proper amount of phosphorus fertilizer is helpful to cultivate robust seedlings.

Key words: phosphorus fertilizer, soil, rice, seedling quality, ‘Liaojing 401’
