水稻的倒伏和不倒伏,对产量的关系很大。去年天津地区的武清、静海、坝县、文安等县培植了30多万亩丰产田,这些丰产田多数没有倒伏,一般亩产在千斤以上,有的三、四千斤。但是也有少数的丰产田发生了倒伏,一般减产20—30%,严重的减产60—70%,甚至有的颗粒无收。有些人认为丰产田发生倒伏的原因是丰产、密植、多肥的结果。是不是因为这些原因而倒伏呢?根据我们调查的

Rice lodging and not lodging, a great relationship between the yield. Last year, more than 300,000 mu of high-yield fields were cultivated in Wuqing, Jinghai, Ba County and Wen’an counties in Tianjin. Most of these high-yield fields were not lopsided. Generally, more than one kilogram of musing per mu was produced, with some three or four kilos.

Some people think that the reason for the lodging of high-yielding fields is the result of high yield, close planting and more fertilizer. Is it because of these reasons that lodging it?
