摘要
通过试验研究了除草和每山种苗数对水稻生产性能的影响。BR16)。采用3个重复的完全随机区组设计,采用3种除草方法和4个水平的苗丘1。结果表明,除草次数对杂草干重有影响。与不除草相比,单手和双手除草减少了杂草的干重。双手除草时,收缩程度更大。根据水稻产量和产量贡献特性的数据,1号苗的数量对产量和所有植株形态参数都有实质性的影响。以总分蘖数1号、有效分蘖数1号、穗数1号、千粒重、籽粒产量(5.02 t hm -1)、生物产量和收获指数为标准,4株苗苗1号达到最高产量。8个苗山-1籽粒产量最低,为2.58 t hm -1。除无效分蘖株数1和穗长外,所有产量贡献性状均受除草量的强烈影响。双手除草产量最高(5.04 t ha-1),单手除草产量最低(3.46 t ha-1)。除株高、无效分蘖hill-1、未灌浆穗-1和千粒重外,幼苗数量hill-1和除草对产量贡献特征的交互影响显著。在20和40 DAS双手除草时,4个苗丘-1的籽粒产量最高(5.79 t ha-1)。
Effect of number of seedlings hill-1 and weeding on the yield of aus rice cv.BR16
An experiment was conducted to ascertain the impact of weeding and the number of seedlings per hill-1on the performance of aus rice (cv. BR16). The treatments consisted of three weeding methods and four levels of seedlings hill-1in a randomized complete block design with three replications. The number of weeding had an impact on weed dry weight, according to the results. Compared to not weeding, one and two-hand weeding decreased the dry weight of weeds. The degree of shrinkage was greater while weeding with two hands. The number of seedlings hill-1had a substantial impact on yield and all plant morphological parameters, according to data on yield and yield-contributing characteristics of aus rice. With criteria like total tillers hill-1, effective tillers hill-1, grains panicle-1, the weight of 1000 grains, grain yield (5.02 t ha-1), biological yield, and harvest index, four seedlings hill-1achieved the maximum yield. In 8 seedling hill-1, the lowest grain yield (2.58 t ha-1) was discovered. Except for non-effective tillers hill-1and panicle length, all yield-contributing features were strongly impacted by the amount of weeding. Two-hand weeding resulted in the best grain production (5.04 t ha-1) and one weeding produced the lowest yield (3.46 t ha-1). Except for plant height, ineffective tillers hill-1, unfilled grains panicle-1, and weight of 1000 grains, the interaction impact of the number of seedlings hill-1and weeding was found to be significant for the yield-contributing features. With two hands weeding at 20 and 40 DAS, the maximum grain production (5.79 t ha-1) was recorded from 4 seedling hills-1.
