江西铜鼓县一季晚稻,每年因受水稻食根金花虫的为害损失不小,我们访问了历年发生食根金花虫的18个生产队,组织农民座谈,初步归纳群众防治的经验如下: 1.适当推迟扦秧期:山区一晚栽得早(立夏),生长期长(收割秋分),对历年发生受害的田,可推迟扦秧期,待食根金花虫幼虫为害盛期已过,再扦秧,适当稀栽,同时要着重前期施肥,促使禾苗加快前期生长,这是避的办法。1964年石门生产队采用这一办法,产量保持常年。 2.早耘禾施药肥:一般栽后12天进行耘禾一
One season of late rice in Tonggu County, Jiangxi Province, due to the damage caused by the damage caused by the goldenrod of rice edible perennial, we visited 18 production teams of goldenrod of edible root perennial and organized peasant talks to initially summarize the experience of the masses in prevention and control as follows: 1 Properly postponed skewed seedling period: In the mountainous area, one planted early in the morning (beginning of summer) and a long growing season (harvesting and autumnal equinox), it is possible to postpone the stem-cutting period for the fields that have suffered in the past years. , And then cut seedlings, appropriate thinning, at the same time to focus on early fertilization, prompting the early growth of grasses to speed up, this is the way to avoid. In 1964 Shimen production team adopted this approach, the output remained perennial. Early morning hematoxylin application of fertilizer: generally cultivated 12 days Yun Wo one
