两年来,我省大面积试种的6A高粱都出现程度不同的倒伏。据调查,除因春旱严重或秋季大风等气象因素影响外,与选地也有密切关系。山谷、河川的风口地段倒伏较重。在选择种植地块时,应避开风口、土层较薄的山坡地和“旱龙道”地段,土质疏松、保墒能力很差的沙薄地,也不宜种植6A高粱。 Over the past two years, a large area of ​​6A sorghum in our province appeared different degrees of lodging. According to the survey, except for the meteorological factors such as severe spring drought or autumn gale, it is also closely related to the election. Valleys in valleys and rivers lodge heavily. When choosing planting plots, we should avoid the tuyere, soil thinner hillside and “dry Long Road” lots, loose soil, poor soil moisture capacity of the sand, it is not suitable for planting 6A sorghum.
