答:超级稻品种(组合)一般植株较高,个体生长量大。如果密度过高,行距小,会引起群体通风透光不良,病虫防治困难。高产栽培密度为每平方米插16蔸,株行距为25厘米×25厘米。也可以在保证每平方米插16蔸的前提下,实行宽行稀植,即行距可以适当增大,株距可以相应缩小。多蘖秧苗每蔸插
A: Super rice varieties (combinations) generally higher plants, large individual growth. If the density is too high, the spacing is small, it will cause poor ventilation and poor population, pest control difficult. High-yielding planting density of 16 每 per square meter, spacing of 25 cm × 25 cm. Can also be inserted in the guarantee of 16 square meters per square meter under the premise of the implementation of wide-spread thin planting, row spacing can be increased appropriately, spacing can be reduced accordingly. Multi-tiller seedlings inserted every time
