再生高粱省种、省工,不用耕种可以增收一季粮食,而且60~70天即可成熟,但农民朋友在实际操作中不规范,致使增产幅度较低。现将其管理技术介绍如下:一、把好季节关。再生高粱能否正常成熟,取决于春播高粱收获期的早晚。因此春播高粱要选用中熟或早熟品种,适时早播或育苗移栽,以尽量缩短春播的生育期,并要适期早收头茬。二、砍秆高低要适当。采用高桩留芽法,在春播高粱新茎节上30厘米左右处割穗,利用茎上部萌发的新芽成穗。在收获头茬高粱时,镰刀
Regeneration of sorghum provincial species, provincial workers, do not have to cultivate a quarter of grain, and 60 to 70 days to mature, but farmer friends in the actual operation of non-standard, resulting in lower yield. Now its management techniques are as follows: First, the good season off. Regeneration of sorghum can mature normally, depending on the spring sowing sorghum harvest sooner or later. Therefore, spring sorghum to use medium maturing or early maturing varieties, timely sowing or transplanting seedlings to minimize the growth period of spring sowing, and to early crop stubble early. Second, cut straw level to be appropriate. Using high-pile retention bud method, sowing about 30 cm on the spring sowing new stem section, using sprout germination on the upper stem. Sickle harvest in the first crop of sorghum
