摘要
采用大田裂区随机区组设计试验,研究免耕不覆盖小麦秸秆(T1)、起垄覆盖小麦秸秆(T2)和免耕覆盖小麦秸秆(T3)3种方式对两个花生品种产量及品质的影响。结果表明,起垄覆盖小麦秸秆(T2)的花生产量最高,比免耕不覆盖小麦秸秆(T1)的和免耕覆盖小麦秸秆(T3)分别增产664.7和818.1kg/hm^2,增产率分别为19.4%和25.0%。在3种方式下,远杂9307分别比远杂6产量增加13.8%、9.9%和15.8%。起垄覆盖小麦秸秆的耕作方式下,花生饱果数、百果重、出仁率等经济性状和株高、侧枝长、分枝数、结果枝等农艺性状最好,且远杂9307的农艺性状优于远杂6。耕作方式与秸秆覆盖对花生籽粒中氮磷钾含量影响显著。起垄覆盖小麦秸秆的花生蛋白质、粗脂肪产量最高,且远杂9307的高于远杂6的。花生起垄种植,小麦秸秆覆盖量为4 500kg/hm^2,远杂9307的花生产量、蛋白质产量和粗脂肪产量均最高,分别为4 290.0kg/hm^2、1 294.3kg/hm^2、1 881.9 kg/hm^2。
The effects of tillage method with straw mulching on peanut yield and quality were studied by field experiment with split- plot randomized block design. The results indicated that peanut yield under ridge tillage combining with wheat straw mulching pattern was higher than that of no- tillage without or with wheat straw mulching patterns,and their yield increase were 19. 4% and 25. 0%,respectively. Pod yields of cultivar Yuanza 9307 were higher than that of cultivar Yuanza 6 under 3 patterns with increase of 13. 8%,9. 9% and 15. 8%,respectively. Peanut economical and agronomic characteristics showed the best results with the combination of ridge tillage and wheat straw mulching,including full pod number,100- pod weight,kernel rate,and plant height,lateral branch length,branch number,valid branch number. These characteristics of Yuanza 9307 were better than that of Yuanza 6 under all 3 patterns. Tillage method and straw mulching had significant effect on NPK content in peanut kernels. Peanut protein and crude fat production with the combination of ridge tillage and wheat straw mulching were the highest,and peanut protein and crude fat production of Yuanza 9307 were greater than those Yuanza 6.Peanut yield,protein and crude fat production of Yuanza 9307 were the highest by ridge tillage with wheat straw mulching,and they were 4 290. 0kg / hm2,1 294. 3kg /hm2,1 881. 9kg /hm2,respectively.
