normal style="TEXT-JUSTIFY: inter-ideograph; MARGIN-LEFT: 0pt; TEXT-INDENT: 18pt; MARGIN-RIGHT: 0pt; TEXT-AUTOSPACE: ideograph-numeric; TEXT-ALIGN: justify; mso-para-margin-right: 0.0000gd; mso-para-margin-left: 0.0000gd; mso-char-indent-count: 2.0000; mso-pagination: none">1、播种节令:我县的最佳播种节令是“立冬”节令即118日至1123日,应按时播种,播种后在种子上面盖土3厘米左右,盖严种子即可。  

normal style="TEXT-JUSTIFY: inter-ideograph; MARGIN-LEFT: 0pt; TEXT-INDENT: 18pt; MARGIN-RIGHT: 0pt; TEXT-AUTOSPACE: ideograph-numeric; TEXT-ALIGN: justify; mso-para-margin-right: 0.0000gd; mso-para-margin-left: 0.0000gd; mso-char-indent-count: 2.0000; mso-pagination: none">2、合理密植:播种量和密度要根据种子千粒重确定,一般每亩播种量710公斤,机播增加到1015公斤,播种要均匀,确保苗整齐。  

normal style="TEXT-JUSTIFY: inter-ideograph; MARGIN-LEFT: 0pt; TEXT-INDENT: 18pt; MARGIN-RIGHT: 0pt; TEXT-AUTOSPACE: ideograph-numeric; TEXT-ALIGN: justify; mso-para-margin-right: 0.0000gd; mso-para-margin-left: 0.0000gd; mso-char-indent-count: 2.0000; mso-pagination: none">四、田间管理

normal style="TEXT-JUSTIFY: inter-ideograph; MARGIN-LEFT: 0pt; TEXT-INDENT: 18pt; MARGIN-RIGHT: 0pt; TEXT-AUTOSPACE: ideograph-numeric; TEXT-ALIGN: justify; mso-para-margin-right: 0.0000gd; mso-para-margin-left: 0.0000gd; mso-char-indent-count: 2.0000; mso-pagination: none">2、追肥:早施分蘖,巧拔节肥。分蘖肥要早施,在麦苗“二叶一心”期每亩施尿素710公斤,硫酸钾5公斤。拔节肥根据苗情少施或不施以免氮肥过多造成倒伏。施肥要结合灌水进行。  

normal style="TEXT-JUSTIFY: inter-ideograph; MARGIN-LEFT: 0pt; TEXT-INDENT: 18pt; MARGIN-RIGHT: 0pt; TEXT-AUTOSPACE: ideograph-numeric; TEXT-ALIGN: justify; mso-para-margin-right: 0.0000gd; mso-para-margin-left: 0.0000gd; mso-char-indent-count: 2.0000; mso-pagination: none">3、灌好四次水:一是出苗水、二是分蘖防冻水、三是拔节孕穗水、四是灌浆水。灌水要做到速灌速排。
