摘要:

为探明化肥减量与生物有机肥配施对黑塌菜生长、产量及品质的影响,设置2种肥料类型(F1,N-P2O5-K2O=15-15-15;F2,N-P2O5-K2O=26-9-9)和7种施肥方式(N1,纯复合肥525 kg/hm2;N2,F减施10%+生物有机肥400 kg/hm2;N3,F减施10%+生物有机肥600 kg/hm2;N4,F减施10%+生物有机肥750 kg/hm2;N5,F减施20%+生物有机肥400 kg/hm2;N6,F减施20%+生物有机肥600 kg/hm2;N7,F减施20%+生物有机肥750 kg/hm2),另设不施肥(CK)为空白对照。按肥料类型和施肥方式二因素随机区组试验,测定黑塌菜的产量构成及品质指标。结果表明:(1)肥料类型与施肥方式的交互作用对黑塌菜大多数农艺性状和单株重都有极显著影响(P<0.01);在不同肥料类型处理下,黑塌菜的叶柄长、叶柄宽、叶片重、叶柄重和单株重均表现为F2>F1,且2种处理的单株重之间差异显著(P<0.05),F2减量与生物有机肥配施更有利于黑塌菜的生长和产量的增加;在F1和F2处理下,黑塌菜的单株重均与开展度、叶片重和叶柄重极显著相关,与叶柄厚不相关;与N1相比,在化肥减施10%和20%与适量的生物有机肥配施时不会对黑塌菜的生长产生影响,且能在一定程度上促进其生长,单株重的增幅可达15.24%。(2)与N1相比,在化肥减施10%和20%与适量的生物有机物配施时不会对黑塌菜可食部分的矿质元素含量产生影响,并有利于矿质元素的积累,但当肥料减量施用过多时,生物有机肥对土壤P、Mg、K、Ca等元素的活化能力会不同程度的降低。(3)肥料类型对黑塌菜硝态氮含量具有极显著影响,肥料类型与施肥方式的交互作用对黑塌菜的粗纤维含量具有极显著影响;化肥减量与生物有机肥的合理配施能够提高黑塌菜的可溶性糖、可溶性蛋白质和维生素C含量,降低硝酸盐含量;不同肥料处理下,黑塌菜的可溶性糖含量、维生素C含量和水溶性蛋白含量均表现为F1>F2,粗纤维含量、全氮含量、硝态氮含量均表现为F2>F1,且2种处理之间的维生素C含量和水溶性蛋白含量差异显著(P<0.05),F1减量与生物有机肥配施更有利于提升黑塌菜品质。化肥减量与生物有机肥的合理配施不仅能在一定程度上促进黑塌菜的生长、增加产量,而且能提升其品质。综合产量和品质因素,F1N6和F2N6可作为本试验条件下较适宜的施肥方式。

Abstract:

To investigate the effects of combined application of bio-organic fertilizer with reduced chemical fertilizer on growth, yield and quality of Brassica campestris ssp. chinensis var. rosularis, two fertilizer types F1 (N-P2O5-K2O=15-15-15), F2 (N-P2O5-K2O=26-9-9) and 7 application amounts, N1 (pure compound fertilizer 525 kg/hm2), N2 (F reduced by 10%+ bio-organic fertilizer 400 kg/hm2), N3 (F reduced by 10%+ bio-organic fertilizer 600 kg/hm2), N4 (F reduced by 10%+ bio-organic fertilizer 750 kg/hm2), N5 (F reduced by 20%+ bio-organic fertilizer 400 kg/hm2), N6 (F reduced by 20%+ bio-organic fertilizer 600 kg/hm2), N7 (F reduced by 20%+ bio-organic fertilizer 750 kg/hm2) were set up in the experiment. And no fertilization (CK) was also set as the blank control. The agronomic characters, yield, mineral elements and quality characters of B. campestris ssp. chinensis var. rosularis were investigated and analyzed according to the two factors of fertilizer type and fertilizer method. The results were as follows. (1) The interaction between the type of fertilizer and the application amounts had extremely significant effects on most agronomic traits and plant weight (P<0.01). Under different fertilizer treatments, the petiole length, petiole width, leaf weight, petiole weight and weight per plant were all showed as F2>F1. The weight per plant was significantly different between the two treatments (P<0.05). The combination of bio-organic fertilizer with reduced chemical fertilizer F2 were more conducive to the growth and yield increase of B. campestris ssp. chinensis var. rosularis. Under F1 and F2 treatments, the weight per plant was significantly correlated with the degree of development, leaf weight and petiole weight, but there was no correlation between plant weight and petiole thickness. Compared with N1, chemical fertilizer reduced by 10% and 20% combined with rational bio-organic fertilizer didn’t affect the growth of B. campestris ssp. chinensis var. rosularis, and could promote their growth to a certain extent. The maximum increase of weight per plant was 15.24%. (2) Compared with N1, chemical fertilizer reduced by 10% and 20% combined with rational bio-organic fertilizer didn’t affect the content of mineral elements in the edible part of B. campestris ssp. chinensis var. rosularis, and had beneficial effect on the accumulation of mineral elements. However, when the fertilizer were reduced too much, the activation ability of bio-organic fertilizer on soil elements such as P, Mg, K, Ca and other elements would be reduced by different degrees. (3) The type of fertilizer had extremely significant effect on the nitrate nitrogen content of B. campestris ssp. chinensis var. rosularis, and the interaction between the type of fertilizer and the application amounts had extremely significant effect on the coarse fiber of B. campestris ssp. chinensis var. rosularis (P<0.01). The combination of rational bio-organic fertilizer with reduced chemical fertilizer could increase the content of soluble sugar, soluble protein and vitamin C, and reduce the nitrate nitrogen content. Under different fertilizer treatments, the contents of soluble sugar, vitamin C and soluble protein of B. campestris ssp. chinensis var. rosularis were all showed as F1>F2, while the content of coarse fiber, total nitrogen and nitrate nitrogen were all showed as F2>F1, and the contents of vitamin C and soluble protein were significantly different between the two treatments (P<0.01). The combination of bio-organic fertilizer with reduced chemical fertilizer F1 were more conducive to improve the quality of B. campestris ssp. chinensis var. rosularis. The combination of rational bio-organic fertilizer with reduced chemical fertilizer could not only promote the growth, increase the yield, but also improve the quality of B. campestris ssp. chinensis var. rosularis. Based on yield and quality factors, F1N6 and F2N6 could be used as suitable fertilization methods under the experimental conditions.
