冬小麦地膜覆盖栽培技术是针对干旱、缺水地区采用的一种播种方式,通过地膜覆盖能达到节水、抗旱、增温保墒效果;使小麦促根增加分蘖、加快群体发育、明显提高穗粒数和千粒重,短缩小麦生育期,有效提高小麦产量。用冬小麦地膜穴播机播种,667米~2基本苗32万株,总茎数70万~80万茎,667米~2成穗数40万~50万穗,单穗粒数25~30粒,千粒重40克,667米~2产量在500千克左右。
Film mulching cultivation of winter wheat is a sowing method for drought and water shortage areas. Water-saving, drought-resistant and temperature-preserving effects can be achieved through plastic film mulching; wheat can increase root tillering, accelerate population development and significantly increase the number of grains per spike And 1000 grain weight, shortened wheat growth period, effectively improve wheat yield. Sowing with winter wheat film seeding machine, 667 m ~ 2 basic seedlings 320,000, the total stems of 700,000 to 800,000 stems, 667 meters to 2 into 400,000 to 500,000 spikes per spike grain number 25 to 30, Thousand grain weight 40 grams, 667 meters ~ 2 output of about 500 kilograms.
