- Abstract:
-
The hilly and gully area of the Loess Plateau in northern Shaanxi is an important production area for mountain apples. In order to improve the soil nutrients, fruit quality and yield of mountain orchards, based on the ‘fertilizer water earthworm pit' measures, through field experiments, effects of different fertilization such as no fertilization, single application of chemical fertilizers, combined application of organic and inorganic fertilizers(cow manure+chemical fertilizer, mushroom residue+chemical fertilizer, cow manure+mushroom residue+chemical fertilizer), on soil nutrients, leaf nutrition, apple yield and quality in mountain orchards had been monitored. The results show that:(1)the soil organic matter content and available nutrients in the treatment without fertilization were lower than those in the fertilization treatment; Among the treatments, the soil organic matter content and available nutrients under single application of chemical fertilizer were lower than those of the combined application of organic and inorganic fertilizers, and the treatment of cow manure+mushroom residue+chemical fertilizer had better effects on improving soil nutrients than other fertilization treatments;(2)the total nitrogen, phosphorus and potassium contents of apple leaves in different growth stages of fertilization treatment were significantly higher than those of no fertilization control, and the combined application of organic and inorganic fertilizers were better than that of single application of chemical fertilizers;(3)there were no significant difference in apple fruit hardness and fruit shape index between no fertilization treatment and fertilization treatment; fertilization treatments had significantly increased apple yield, soluble solids, soluble sugar and vitamin C content, and cow manure+mushroom residue+chemical fertilizer was better than other treatments; The titratable acid content of single application of chemical fertilizer was significantly higher than that of no application and combined application of organic and inorganic fertilizers; there were no significant difference between the sugar-acid ratio of single application of chemical fertilizer and no application of fertilizer, but they were significantly lower than that of combined application of organic and inorganic fertilizers. To sum up, the combination of ‘fertilizer water earthworm pit' combined with organic and inorganic application could reduce the application rate of chemical fertilizers, increase soil nutrient content, and ensure the quality and production of apples. Cow manure+mushroom residue+chemical fertilizer was a high-quality management model for mountain apples to improve quality and increase production. Cow manure+mushroom residue+chemical fertilizer(cow manure:mushroom residue=1:1 should be popularization and application in mountain orchards in the loess hilly and gully regions of northern Shaanxi.
