1, chickens can weeding, but also exterminate: chickens have the habit of feeding grass and grass seeds, weeds have a certain degree of control and inhibition. According to the experiment, 20 chickens were stocked in each orchard orchard, only about 20% of the control orchards, the number of chickens increased, and weeds were fewer. When the chickens eat in the orchard, they can eat most of the pests on the ground and grass in the orchard, so as to reduce the damage of pests to fruit trees. 2. Improve orchard soil fertility and reduce fertilizer investment: chicken manure contains elements needed for the growth of fruit trees such as nitrogen, phosphorus, and potassium. According to the analysis, the feces of 1 chicken contained 1 year of 900 grams of nitrogenous fertilizer, 850 grams of phosphate fertilizer, and 450 grams of potash. If 20 chickens were raised per acre orchard, it would be equivalent to applying 18 kg of nitrogen fertilizer, 17 kg of phosphate fertilizer, and potassium fertilizer. 9 kilograms, not only improve the soil fertility, promote fruit tree growth, save fertilizer, and reduce investment. 3, to enhance chicken population, reduce disease occurrence: Orchard chicken, comfortable environment, is conducive to the growth and development of chickens and reduce the incidence of disease. In addition, the orchards keep chickens away from the village, which can avoid and reduce the spread of chicken diseases. To raise chickens in orchards, we must pay attention to doing a good job of immunization in order to be effective.
