1. Biogas fertilizer as base fertilizer
According to the size of the tree, ditch or open the fruit trees, or dig 4-6 pits with a depth of 30-40 cm, apply 2500-3000 kg of biogas fertilizer mixture per acre, mix 50 kg of formula fertilizer, and cover the soil after application. Conditional irrigation can be done, and the soil should be filled in time after the water is infiltrated to ensure fertilizer efficiency and prevent frostbite roots.
The biogas fertilizer is generally applied in the autumn from September to October. Because this is the peak growth of the root system, and the soil temperature is suitable, it is conducive to further decomposition and root absorption of fertilization, increasing the utilization rate of fertilizer. It is also possible to carry out spring application, generally to master "early", and immediately after the soil is thawed, which is beneficial to promoting the growth of fruit tree leaves and improving the quality of flower buds.
2, biogas slurry for root dressing
The application of biogas slurry is beneficial to the growth and development of shoots and leaves, promote flower bud differentiation, increase fruit set rate and enhance fruit growth. Dig 30 cm × 20 cm strip ditch or 20-30 cm deep pit on the outer edge of the canopy, apply about 30 kg of biogas slurry per plant per plant, and cover the soil in time after the biogas slurry is infiltrated.
The biogas slurry is used as a root top dressing. It is usually carried out about 30 days before fruit picking and fruit picking, and it is topdressed 3-5 times a year.
3, biogas slurry for foliar topdressing
Fertilization time. Generally, the canopy is sprayed before the fruit tree enters flowering, after flowering, before flower bud differentiation, during fruit expansion and after fruit picking.
Spray method. The biogas slurry is sprayed separately on the foliar surface. Each plant is sprayed with 20 kg of biogas slurry and sprayed on the canopy. It is sprayed once every 15 days, so that the back of the leaf is soaked but the fertilizer is not dripping.
Foliar sprayed biogas slurry, fast absorption, high utilization rate, can make fruit leaf surface thicker, reduce the occurrence of pests and diseases and enhance the resistance of the tree body, which is conducive to flower bud differentiation, flower preservation and fruit preservation.
4. Effect of applying biogas fertilizer on yield and quality of apple
The application of biogas fertilizer can significantly improve the apple fruit shape index. The fruit surface is smooth and tidy, with few or no spots. The fruit is large, the specific gravity is small, the coloring area is large, the whole red fruit rate can reach more than 90%, and the fruit yield rate is close to 85%. The fruit has a high hardness and a significant increase in soluble solids. In addition, vitamin C, crude protein, crude fiber, etc. in the fruit also increased significantly.
The apple orchard applied by the biogas fertilizer has an increase rate of 5%-12%. The apple orchard to which the biogas fertilizer is applied can increase the income by 900 yuan per mu and the savings of 220 yuan.

The application of biogas fertilizer in the apple orchard can not only satisfy the nutrients needed for fruit tree growth, but also enhance the soil's ability to retain water, protect fertilizer and drought, and enhance the stress resistance of fruit trees, reduce pests and diseases, and improve yield and quality.
