- 摘要:
- 为探讨旱稻在分蘖期的最适土壤含水量，以旱稻74和旱稻80为试验材料，通过盆栽方式，人为控制土壤水分，研究了分蘖期不同土壤水分对旱稻生长发育及产量的影响。结果表明：土壤水分控制
- Abstract:
- In order to investigate optimal soil moisture content during tillering period of upland rice,using Handao74 and Handao80 as experimental materials,to study the effects of different soil moisture treatments on growth and yield of upland rice during tillering period through potted experiment and artificially controlled water.The results showed that:When the soil moisture control Less than treatment 6(soil relative water content 90%-100%).It could affect plant height and dry matter accumulation of upland rice; When the soil moisture control Less than treatment 5(soil relative water content 80%-90%).It could affect the growth period and tiller number of upland rice.The soil moisture control Less than treatment 6(soil relative water content 90%-100%),the yield of Upland Rice decreased obviously,and the difference compared to other treatments was significant.In order to ensure normal plant growth,soil moisture control must be more than treatment 6(soil relative water content 90%-100%),otherwise it will obviously affect the final yield of upland rice.
