近年来,水稻机插秧发展迅速,相关技术逐渐成熟.为进一步研究不同栽插期对机插秧水稻产量及品质的影响,以淮稻 5 号为研究对象,进行 4 个栽插期处理的对比试验.结果表明:栽插期对机插秧水稻产量有明显影响,以 6 月 15 日栽插产量最高,较 6 月 30 日栽插增产 5.3%,在秧龄相近的情况下,栽插越晚产量越低;随着栽插期的推迟,稻米加工品质和外观品质总体呈下降趋势.生产上应抓住适期,争取早栽,以实现水稻产质量的提高.
Rice machine transplanting has developed rapidly in recent years,and the related technologies of machine transplanting have gradually matured.In order to further investigate the effects of different transplanting periods on the yield and quality of machine transplanted rice,this paper conducted a comparative experiment on Huaidao 5 with four transplanting periods.The results showed that the transplanting period had a significant effect on the yield of machine transplanted rice.The highest yield was achieved in June 15th transplant period treatment,with an increase of 5.3%compared with June 30th transplant period treatment.In cases of similar seedling ages,the later the transplanting,the lower the yield.As the planting period was delayed,the processing quality and appearance quality of rice showed a downward trend.In production,we should seize the appropriate time and strive for early planting to achieve improvement in yield and quality.
