1 早间苗,早定苗,合理密植。“谷间寸,如上粪”。旱地夏谷早间苗可促壮苗;晚间苗,幼苗之间争水争光,个体发育不良,易造成苗荒。一般可在幼苗4叶1心时间、定苗,争取在7叶前全部间完。间苗时应采用三角留苗法,苗距3～4cm,间去弱苗、杂色苗、小苗,667m~2留苗4～5万株。 2 三砘、三锄,壮根促穗。播后“三砘”、“三锄”是旱地夏谷壮苗、壮根、促秆、促穗的重要措施。三砘是:播后砘,随播种随砘压一次,使种子与土壤紧密接触,利其吸水萌动;砘黄芽,播后三天芽鞘出土时进行第二次镇压;砘青尖,谷子长到一叶一心时进行第三次镇压。砘压要在晴天下午进行,砘干不砘湿。通过砘压,可促使谷苗墩壮健
1 morning seedlings, early seedlings, close planting density. “Valley inches, such as the above feces.” Dry summer summer valley seedlings can promote strong seedlings; evening seedlings, seedlings compete for water Zhengguang, individual poor development, easy to cause shortage of seedlings. Generally 4 leaves in a seedling 1 heart time, Dingmiao, for all in the 7 leaves before the end. Mature seedlings should be used triangular stay Miao method, the seedling spacing 3 ~ 4cm, between the weak seedlings, variegated seedlings, seedlings, 667m ~ 2 stay seedlings 4 to 5 million. 2 three 砘, three hoe, strong roots spike. After sowing “three”, “three hoe” is the dry summer Xiagu strong seedlings, strong roots, promoting stalk, an important measure to promote spike. Sanyuan is: after sowing, with sowing with pressure once, so that the seeds in close contact with the soil, its beneficial water sprout; 砘 yellow buds, sowing three days after sowing unearthed when the second suppression; 砘 green tip, millet The third crackdown took place when one leaf was taken care of. Pressure to be carried out in the sunny afternoon, 砘 dry wet. Through pressure, can promote Valley Miao pier strong
