稗草对水稻危害极大,一株夹心稗草除能“吃”掉本撮秧苗外,还会使周围4—8撮水稻生长不良。据调查,一亩稻田如有300—400株稗草,就要减产一成以上,还将降低米质。由于稗草具有强大的繁殖能力,结籽数量多,不怕旱涝,具有特殊的抗逆能力。种皮厚有蜡质,不易丧失发芽力,甚至在40℃的厩肥中,仍能保持生活力达一个
Barnyardgrass is very damaging to rice. In addition to being able to “eats” the seedlings of a bunch of barnyardgrass, it can also cause poor growth of the rice around 4-8. According to the survey, if there is 300-400 barnyard grass per acre of rice field, it is necessary to cut down more than 10%, and will also reduce the quality of rice. As barnyard grass has a strong reproductive capacity, the number of seeds, not afraid of drought and flood, has a special resilience. Seed coat thick wax, not easy to lose germination, even in the 40 ℃ manure, still maintain the viability of a
