不同播种期对杂交晚稻天优8019产量及农艺性状的影响
Effects of Different Sowing Dates on Grain Yield and Agronomic Characteristics of Hybrid Rice Combination Tianyou 8019
摘要
Abstract
Comparative experiment of five sowing dates and one transplanting date was conducted in field. The results showed that Tianyou 8019 belongs to temperature-sensitive variety, but the variation of seedling age is larger. In this experiment, Tianyou 8019 was planted in Quzhou as late rice. It has compact plant type, high lodging resistance, high spike rate and grain number, bigger pani-cles and high yield potential. However, suitable sowing date is the key to get high yield. In this experiment, sowing date at June 20 to 25, keeping seedling age at 30~35 d, transplanting at suitable leaf age 8.9~9.4, maintaining 3.08~3.27 vegetative growth leaves were key cultural techniques to achieve the high yield and high efficiency.关键词
