【摘要】：在豫南稻區(qū),通過田間試驗(yàn)研究了翻壓不同量紫云英配施減量化肥對土壤肥力和水稻產(chǎn)量的影響。本研究在化肥減量20%和40%條件下,將紫云英翻壓量設(shè)22.5、30、37.5、45 t/hm~24個水平,另設(shè)僅施用100%化肥處理作為對照。結(jié)果表明,與對照相比,減施20%和40%化肥配施紫云英可使土壤堿解氮分別增加14.4%~20.9%和13.5%~26.5%,有機(jī)質(zhì)分別增加4.5%~10.8%和4.2%~8.2%,差異均達(dá)到顯著水平。水稻產(chǎn)量隨著紫云英翻壓量的增加出現(xiàn)先升后降趨勢,在減量20%化肥條件下,翻壓30 t/hm~2紫云英時水稻產(chǎn)量最高,比對照增產(chǎn)16.7%,差異極顯著;而在減量40%化肥條件下,翻壓37.5 t/hm~2紫云英時水稻產(chǎn)量最高,比對照增產(chǎn)15.3%,差異極顯著;與對照比較,翻壓紫云英極顯著提高了水稻有效穗,但每穗實(shí)粒數(shù)較對照有所降低。
[Abstract]:In the south Henan rice region, the effects of different amount of Ziyunxiao and reduced chemical fertilizer on soil fertility and rice yield were studied through field experiments. Under the condition of fertilizer reduction of 20% and 40%, the pressure turning rate of Ziyun was set at the level of 22.5g ~ 37.5 t / hm ~ 24, and only 100% chemical fertilizer was applied as the control. The results showed that 20% and 40% chemical fertilizer combined with Zyunyunyue could increase soil alkali-hydrolyzed nitrogen by 14.4% and 13.5%, respectively, and increase organic matter by 4.510.8% and 4.22%, respectively. The difference reached a significant level. The yield of rice increased first and then decreased with the increase of the pressure of Ziyunying. Under the condition of reducing 20% chemical fertilizer, the yield of rice increased 16.7% higher than that of the control under the condition of reducing 20% chemical fertilizer for 30 t/hm~2, and the difference was very significant, but under the condition of 40% less fertilizer, the yield of rice increased significantly. The yield of rice was the highest when the pressure was 37.5 t/hm~2, and the yield was 15.3% higher than that of the control, the difference was significant, compared with the control, the effective panicle of rice was increased significantly, but the number of grains per panicle was lower than that of the control.
