摘    要:[研究目的]研究水稻本田施用石灰对水稻生长发育及抗病性的影响;[方法]利用大区对比的方法;[结果]施用石灰的处理水稻鞘腐病和褐变粒的发病程度明显较CK轻,施石灰450kg/hm^2的处理效果最明显。石灰用量与褐变粒的发病程度和病情指数呈显著负相关。施石灰的处理水稻穗大、穗整齐、小穗少、植株衰老过程慢.随着石灰用量的增加穗长、穗总粒数、穗实粒数和产量均呈递增的趋势。施石灰450kg/hm^2的处理稻谷产量9552.0kg/hm^2,比对照增产9.2%。施石灰225kg/hm^2的处理稻谷产量8802.0kg/hm^2,比对照增产0.68%。[结论]水稻本田施用石灰对水稻生长发育和抗病性均有较好的影响。

Abstract:[OBJECTIVE]It is studied that the effect by allocate acid using the lime on disease-resistant and planting of paddy rice on the Honda; [METHOD]using of contrast method; [RESULTSIThe morbidity degree of rotten disease of vagina and brown granule using the lime treatment is lighter than CK, the effect is the most obvious of using lime 450 kg/hm^2 treatment. It is negative notable relevance between the lime dosages and the morbidity degree of brown granule. Tassel rice is bigger and tidier of the paddy and the speed old and feeble of plant is slower, the tassel length and general granule number and solid granule number and output are raised with increasing the lime dosages. The output is 9552.0 kg/hm^2 using lime 450kg/hm^2 treatment, Output is higher 9.2% than CK, The output is 8802.0kg/hm^2 using lime 225 kg/hm^2 treatment, Output is higher 0.68% than CK;[CONCLUSION]Using lime on Honda has good effect on growth growth and disease resistance of paddy rice.
