The methods of organic fertilizer equipment to improve apple yield are mainly reflected in the following aspects:
1. Substitution of organic fertilizer for fertilizer nitrogen: Field experiments for many years have found that substitution of organic fertilizer for fertilizer nitrogen can significantly increase apple yield. Compared with farmers' traditional fertilization, optimized fertilization and treatment with organic fertilizer instead of 25% fertilizer nitrogen significantly increased apple yield in the following 3 years.
2. Improve apple quality: The quality of apples replaced by organic fertilizer is better than that of traditional fertilizer treatment, and with the increase of experiment years, the higher proportion of organic fertilizer treatment has a more significant effect on apple quality improvement. Organic fertilizer significantly increased the Vc content, sugar content and sugar-acid ratio of fruit, and significantly reduced the acidity of fruit.
3. Reduce the amount of fertilizer: The organic fertilizer replacement fertilizer fertilization technology plan issued by the Ministry of Agriculture mentioned that the autumn fertilization can use cow manure, sheep manure, pig manure and other fully decomposed farm manure, or commercial organic fertilizer, or soybean meal, soybean cake, or commercial biological organic fertilizer, while reducing the amount of fertilizer.
4. Fertilization technology scheme: Organic fertilizer is used to replace part of chemical fertilizer on apples. The yield and quality of apples in Weibei dryland orchard can be improved more effectively by optimizing fertilization mode, adjusting fertilization amount and time, and combining with tree plate covering film and interrow planting of small rapeseed.
Through the above methods, the organic fertilizer production line can improve the apple yield at the same time, but also improve the fruit quality, improve the fruit marketability, and promote the green, healthy and sustainable development of apple orchards.
