【摘要】 应用少、免耕方法种麦,适应农村产业结构改革的社会需要与江苏省的自然条件,平均单产明显提高,推广迅速已成为江苏主要耕种方法之一。江苏的少、免耕种麦,除了有与国内外其它地方相同的省工、节支、争取农时等共同点外,另有它的本身特色,它可以抗湿播种,並避免湿地耕作的一系列弊病。少、免耕所保持的土体构造,为改善播种质量、苗床水分、温度、养分等条件提供了前提基础,因而能促进幼苗早发、增穗、增产。此外少、免耕种麦还为除草提供了有利条件。本文对上述内容从理论上进行了分析,並对草害根系生长等问题进行了讨论。更多还原

【Abstract】 The no-tillage or minimum-tillage of wheat, which suited to the reforming of the structure of rural economy and to the natural condition of Jiangsu Province, which increases the yield obviously, has been popularized rapidly, bence become one of the main autumn-sowing ways at present in Jiangsu Province.Apart from the same advantages of saving labour and capital and grasping the sowing seasen easily as other parts and regions in the world, the no-tillage or minimumtillage wheat sowing method in Jiangsu Province has its own characteristics. It allows the method to be sown in wetter fields and can avoid a series of bad results brought about by wetter-ploughing. This method can also protect the stucture of soil body and lays a solid foundation for upgrading sowing quality and improving the condition of water, temperature and nutrition in seedbed. It can make seedlings growth rapidly and increase heads, thus increasing the yield per unit. Besides this method creates a good condition for weed control.This paper will analyse the above mentioned contents and discuss such problems as the growth of rootage, etc.更多还原
