水葫芦有机肥与化肥配施对青椒生长、产量和氮素利用率的影响
Ef fects fo Combined Application of Organic Compost from Water Hyacinth and Chemical Feritil zer on Growth, Yielda nd Nitrogen Use Efficiency of Green Pepper
摘要
Abstract
The water hyacinth ( Eichhornia crassipes ) organic compost ( WHOC ) was made from the mixed fermentation of water hyacinth residue and pig manure , and the effects of the combined application of WHOC and chemical fertilizer ( CF) on the growth, yield and nitrogen use efficiency of green pepper were studied .The following five treatments were designed according to the ratio of WHOC application rate to CF application rate:treatment F4, 0∶4;H1F3, 1∶3;H2F2, 2∶2;H3F1, 3∶1;H4, 4∶0.The re-sults indicated that:under the condition of equal nitrogen application rate , the biomass of green pepper in the treatments F 4 and H1 F3 was obviously higher than that in the treatments H 2 F2 , H3 F1 and H4 .The supplement of WHOC could significantly promote the growth of the underground part of green pepper , and the root system volume and root tip number of pepper plants in the treatment H3 F1 were respectively 77.87%and 56.12%more than those in the treatment F 4 .The single-plant fruit yield of green pepper in the treatment H2F2 was the highest, being the 1.6 times that in the treatment F4.The nitrogen content in the aboveground part of green pepper in the treatment F 4 or H1 F3 was significantly higher than that in the other treatments .The fruit yield, agronomic nitrogen use efficiency and physiological nitrogen use efficiency of green pepper in the treatments H 2 F2 and H3 F1 were significantly higher than those in the treatment F4 or H4.Therefore, the treatment H2F2 had the best effects, and the highest substitution rate of WHOC for CF in the combined application should not exceed 75%.关键词
