Rice growing in Jiangsu, Yangzhou is affected by persistent high temperature 郑宜兰

[Jiangsu] Yangzhou region meteorological rice growth affected by the continuous high temperature Sina fund exposure table: the letter Phi lag of false propaganda, long-term performance is lower than similar products, to buy the fund by the pit how to do? Click on [I want to complain], Sina help you expose them! Since August 7th, Jiangsu City, Yangzhou suffered a continuous high temperature weather of nearly 20 days, in order to understand the influence of high temperature weather, hybrid rice filling in August 25th, Yangzhou City Agricultural Technology Extension Station invited Yangzhou University College of agriculture and Dai Q Huo Yang two professors to Yizheng hilly area of rice field tread field view the disaster situation. Experts visited the Chen Yizhen set, pond, Tongshan, Ma Ji Township rice growth situation, asked in detail about the farmer’s rice seeding, transplanting, heading date of rice, carefully check the panicle spikelet degradation and fructification. It is understood that this year, Yangzhou Yizheng City, mainly concentrated in Hybrid Rice Heading around August 10th, according to meteorological department monitoring shows that in August 10-25 days, the highest temperature in Yizheng area at about 35 to 13 days, the highest temperature reached 36.6 degrees, and the critical temperature of Rice Flowering fertilization short-term high temperature burns is 35 DEG C, the flowering rice pollination is blocked, resulting in infertility of empty grains. Hit the field crop before most of the idle land, rice sowing earlier, from late April to early May sowing, spike differentiation and flowering stage encounter high temperature, influence of pollination and fertilization. In this regard, experts suggest that one should sowing rice in hilly area of Yizheng suitable sowing date for the May 5-10; two to select some high temperature resistant varieties; the three is the flowering stage in high temperature above 35 DEG, should be timely irrigation water, creating a paddy field microclimate, lower temperature.

【产区气象】江苏扬州水稻生长受持续高温影响 新浪基金曝光台:信披滞后虚假宣传,业绩长期低于同类产品,买基金被坑怎么办?点击【我要投诉】,新浪帮你曝光他们!   8月7日以来,江苏扬州市遭遇了连续近20天高温天气,为了解高温天气对杂交籼稻灌浆结实的影响,8月25日,扬州市农技推广站邀请了扬州大学农学院戴其根和霍中洋两位教授前往仪征丘陵地区实地踏田查看水稻受灾情况。   专家一行先后考察了仪征陈集、月塘、铜山、马集等乡镇水稻生长情况,详细询问了种稻农户水稻播种、移栽、抽穗等日期,仔细查看了穗部颖花退化和结实情况。据了解,今年扬州市仪征杂交籼稻主要集中在8月10日左右抽穗,另据气象部门监测显示,8月10-25日,仪征地区最高气温在35℃左右的天数达到13天,最高温度达到36.6℃,而水稻开花受精短期高温灼伤的临界温度为35℃,此间开花的水稻授粉受精受阻,导致不育空粒。受灾严重的田块前茬大部分为空闲田,水稻播期偏早,于4月下旬至5月初播种,穗分化及抽穗扬花期遭遇高温,影响授粉受精。对此,专家建议,一要适期播种,仪征丘陵山区籼稻适宜播期为5月5-10日;二要选择一些耐高温品种;三是抽穗扬花期若遇35℃以上高温,应及时灌深水,营造稻田小气候,降低温度。(扬州农委) 进入【新浪财经股吧】讨论相关的主题文章:
