我区冬小麦单产一般在300公斤左右,高产地块亩产可达400公斤。1991年以来,随着技术措施和生产条件的改善,每年都出现了一些亩产超500公斤的高产地块。现将其高产性状及栽培要点总结如下: 一、产量构成指标:通过三年来对高产地块的调查得出,我区亩产500公斤小麦的性状指标为:亩基本苗28—63万,冬前亩茎数75—90万,最高分蘖105—130万,亩穗数45—50万,穗粒数28粒以 My area winter wheat yield is generally about 300 kilograms, high-yield plots yield up to 400 kilograms. Since 1991, with the improvement of technical measures and production conditions, some high-yield plots of over 500 kilograms per mu have emerged each year. Now its high yield traits and cultivation points are summarized as follows: I. Yield Components Index: Through the investigation of high yield plots in the past three years, the yield traits of 500 kilograms of wheat in our district are as follows: 28-63 thousand mu of basic seedlings, Before the number of acres of stem 75-90 million, the highest tiller 105-130 million, ear number 45-50,000 acres, grain number 28 to
