与传统紫云英4月压绿相比,紫云英带籽翻耕则是在单季稻秧苗移栽前的6月初紫云英黄枯种子完全成熟时用旋耕机一并翻入稻田。结果表明,稻田翻耕带籽紫云英可以使水稻产量提高,迅速改善土壤理化性质。带籽紫云英施用量为11 250~45 000 kg/hm2(干草率21.7%)时,当年稻田土壤有机质含量平均增加5.9%,水稻产量增加10.1%~14.1%;且当年水稻收割后紫云英自然出苗,第2年又会有带籽紫云英27 000~31 500 kg/hm2(干草率23.1%)翻入稻田,到第3年有机质含量增加9.8%,水稻产量增加12.4%~17.2%;并使土壤全氮、碱解氮含量增加,使有效磷、速效钾相对释放增加。稻田翻耕带籽紫云英收到了一次播种、多年受益的功效,起到了生态培肥连年增产的效果。
Compared with the traditional Chinese vermilion green in April, the purple vermilion seed-tillage transplanting into the paddy field with the rotary cultivator when the yellow vermilion seed completely ripened before the single-season rice seedling transplanting in early June. The results showed that paddy field tillage with Ziwenyin could increase the yield of rice and rapidly improve the soil physical and chemical properties. With the application rate of 11 250 ~ 45 000 kg / hm2 (hay rate 21.7%), the content of organic matter in paddy soils increased 5.9% and the yield of rice increased 10.1% ~ 14.1% In the second year, there were 27000 ~ 31 500 kg / hm2 of seedlings of Astragalus mongolica (hay rate 23.1%) in paddy field. By the third year, organic matter content increased 9.8% and rice yield increased 12.4% ~ 17.2 %; And make the soil total nitrogen, nitrogen content increased, so that available phosphorus, available potassium relative release increased. Paddy field tillage Zi Ziying received a sowing, the benefits of years of benefit, played a fertile perennial yield stimulation effect.
