我专区水稻田分布面积占整个耕地面积的60%左右,其中“冬水田”占总水田面积的70%.提高“冬水田”的肥力办法很多,农民有着极为丰富的经验,农民常说:“7月犁田一碗油,8月犁田半碗油,9月犁田光骨头”,说明犁冬水田的板田早迟对于恢复和堤高土壤肥力有很大的作用.根据我所近几年来对早犁冬水田的板田试验研究,说明早犁冬水田的板田可以显著提高土壤肥力,主要表现在以下几个方面:显著消灭杂草;改善土壤的物理、化学性能,促使有效氮、磷肥增多,从而取得稳定而高额产量.
My area paddy field distribution area accounts for about 60% of the total cultivated area, of which “winter paddy field” accounts for 70% of the total paddy field area.Improve the “winter paddy field” a lot of fertility, farmers have a very rich experience, farmers often say: Plowing a bowl of oil in July, plowing half a bowl of oil in August, plowing the fields in September bones ", indicating plow paddy fields in winter paddy fields for the restoration and dike high soil fertility has a great role.According to my recent In recent years, paddy fields in early plowed winter paddy fields have shown that paddy fields in early plowed winter paddy fields can significantly improve soil fertility, mainly in the following aspects: significant weeds elimination; improvement of soil physical and chemical properties, and promotion of effective nitrogen , Phosphate fertilizer increased, so as to achieve stable and high yield.
