培育壮秧是沙田地区水稻增产的一个重要环节,而目前早稻秧苗普遍存在烂秧率高,整齐度差,前期生长幼弱,后期叶片徒长等现象,植后发根慢,囘青迟,未能育成壮秧。究其原因,主要是:秧田不平,催芽不齐,基肥不足,追肥过迟及灌排不当等等。而形成秧苗生长参差不齐,烂秧、弱秧较多的主要原因是催芽不当。一般来说,沙田地区早稻的浸种催芽方法比较粗放,谷堆大,翻堆少及用草蓆围垫谷种,保温、保湿效果不好。谷堆内外的温
Cultivating strong seedling is an important part of rice yield increase in Shatian area. At present, there are common phenomena such as high rate of rotten seedling, poor regularity, weak growth in the early stage and extra long leaves in early rice seedling. Breeding strong seedlings. The reason is mainly: uneven seedling, irregular budding, lack of basal fertilizer, late top dressing and improper irrigation and so on. The formation of uneven seedling growth, rotten seedling, weak seedling more mainly due to germination improper. Generally speaking, the method of seed soaking and sprouting of early rice in Shatian area is rather extensive. Inside and outside the valley heap temperature
