本省大部分地区处在全国年辐射量的低值区。小麦生育期阴雨日多,日照少,特别在抽穗扬花期雨量大,风大,常造成丰产田的大面积倒伏,一般减产30～40％。思南县常年3、4月间有暴风雨,倒伏更是夺取小麦高产的主要障碍。因此,研究小麦高产倒伏原因,探求对策,对小麦生产实为重要。本人就小麦品种、施肥、密度、中耕、喷射矮壮素等因素与小麦倒伏之间的关系进行初步试验研究。
Most parts of the province are in the low-value area of annual national radiation. Rainy days in wheat growing season, less sunshine, especially in the heading and flowering period rainfall, windy, often caused by large areas of high-yielding lodging, the general reduction of 30 to 40%. Sinan County in April and April perennial storm, lodging is the main obstacle to the high yield of wheat. Therefore, the study of the reasons for high yielding wheat to explore ways to deal with wheat production is really important. I conducted a preliminary experimental study on the relationship between wheat varieties, fertilization, density, cultivating, spraying CCC, and wheat lodging.
