上海郊区早稻绝大部分都是籼稻,这些品种一般都具有分蘖穗多,成熟不一致,容易落粒的特点。往往主茎穗已经黄熟,但藏在叶子下面的分蘖穗还在灌浆或乳熟阶段,这时候收割不但秕谷多,千粒重低,影响产量,而且青米多,碾米易碎,品质降低。如果作种子用,则因生活力弱,影响发芽率 Most suburbs of Shanghai are indica rice early rice, these varieties generally have more tiller spike, mature inconsistent, easy to fall characteristics. Often the main stem spike has been ripe, but the hidden tiller spike below the leaves is still grouting or milky stage, this time not only the harvest more than the valley, a thousand low weight, affecting yield, and more green rice, rice fragile, lower quality. If used for seeds, due to weak life, affect the germination rate
