春风解冻,抓紧时机种足种好春小麦。农谚说“麦种凌碴,亩收石八”、“麦坐凌碴冰,一亩收千斤”,说明顶凌播种是春小麦的一项增产措施。春小麦发芽对土壤温度要求不高,水份充足时,0℃以上即可萌动,2-3℃开始发芽,4-6℃时发芽迅速整齐,幼苗能抗-6℃的低温。所以应该充分利用冬季土壤贮存的水份,在早春土壤刚解冻时,抓紧时机,顶凌播种。早播的好处是:根系发育好,增强抗早能力;幼苗在早期低温下延
Spring breeze thaw, seize the opportunity to plant a good spring wheat. Agricultural proverb said that “wheat Ling Ling bald, acres of income eight”, “wheat sit bald ice, acre received pounds”, indicating the top Ling sowing is an increase of spring wheat measures. Spring wheat germination on the soil temperature is not demanding, adequate moisture, 0 ℃ above can be sprouting, 2-3 ℃ germination, 4-6 ℃ germination quickly and tidy, seedlings can resist -6 ℃ low temperature. Therefore, we should make full use of the moisture stored in the winter soil, just thaw in the early spring soil, seize the moment, the top Ling sowing. The benefits of early sowing are: root development, enhance resistance to early abilities; seedlings in the early low temperature extension
