广西壮族自治区灵山县,在去年晚稻和今年早稻生产中,广泛采用根外喷磷的措施,经过对比试验,在相同的生产条件下,一般每亩可增产30—50斤。 灵山县对水稻广泛采取根外喷磷的措施,是在去年晚稻抗御“寒露风”开始的。当时,正当全县40万亩晚稻抽穗扬花时,连续十天遭受“寒露风” 的袭击,占晚稻面积70%的迟熟品种受害较重。丰塘公社丰塘大队沙荫生产队科研小组,在对受灾禾苗灌水、喷水中,把1972年对晚稻进行根外喷磷,使禾苗青枝蜡秆、谷粒饱满的经验应用到抗御“寒露风”上,效果很好。县委及时在丰塘公社召开抗灾夺丰收现场会,使这个经验迅速推广到全县。10天时间全县共喷磷67万多亩次。结果,全县晚稻不仅不减产,还比1972年晚稻增产4,000多万斤,增长一成多。今年早稻灌浆期间,广大干部、群众运用去年晚稻根外喷磷的增产
Lingshan County, Guangxi Zhuang Autonomous Region, late last year and this year’s early rice production, widely used measures to root out phosphorus, after a comparative test, under the same production conditions, the general increase of 30-50 kg per mu yield. Lingshan County, extensive use of rice to root out of phosphorus measures, is to resist late last year, “Cold Dew” began. At that time, just when the 400,000 mu of late rice was heading for flowering in the county, it suffered 10 consecutive days of “cold dew wind” attacks, accounting for 70% of the late rice varieties suffering from heavy late-maturing varieties. Feng Tong commune Fengtang brigade Shayin production team research group, in the affected grasses irrigation, water spray, the late rice in 1972 on the outside of phosphorus, the grasses Qingzhi wax culm, grain full experience applied to the defense “ Cold dew, ”the effect is very good. County Party Committee held a timely Feng Feng commune wins the scene of the harvest will be harmed to make this experience quickly extended to the county. 10 days the county a total of more than 670,000 acres of phosphorus spray. As a result, the county’s late rice not only did not reduce production, but also produced more than 40,000 kilograms of rice in late 1972, an increase of over 10%. During the early rice paddy planting this year, a large number of cadres and the masses used the increase in phosphorus that was sprayed out of the root of late rice last night
