早稻杂优具有优势强,产量高,抗性好等优点。自从开始推广以来,面积从无到有,从小到大到全面铺开,现在全国早稻区大部分已推广种植。但是不管是其推广速度还是其规模,都远远不能与晚稻杂优相比。 1.思想上重视不够,措施上不得力早稻杂优分蘖力强,穗大粒多,结实率高,抗逆性强,增产潜力大,一般亩产比常规稻增产100公斤以上,增长率达20～30%,增产十分显著,但是一些地区粮食较充足,加上重工轻农思想的影响,对推广早稻杂 Zao Youzao has the advantages of strong advantages, high yield, good resistance and so on. Since its inception, the area has grown from nothing to the full extent, and now most of the early rice areas in the country have been popularized. However, whether it is to promote its speed or its scale, are far from comparable with late rice hybrid. 1. Insufficient ideological attention and inadequate measures In early rice hybrids, the tillering ability is strong, the spikelets are large, the seed setting rate is high, the resistance is strong, and the yield potential is large. Generally, the yield per mu is 100 kg more than that of the conventional rice with an increase rate of 20 ~ 30%, yield is very significant, but some areas more adequate food, coupled with the thinking of heavy industry light agricultural impact on the promotion of early rice hybrid
