Chicken manure is not only a good basal fertilizer, but also a good fertigation fertilizer. It is not inferior to the commodity fertilization in increasing vegetable yield and improving vegetable quality. Especially in summer, it is widely used by vegetable farmers because it is more convenient to use chickens. However, after entering the autumn, the weather began to turn cold, and the greenhouse began to gradually turn into a management stage with insulation as its main purpose. The time for closing the shed was prolonged, and the state of the shed was too long, which often caused the accumulation of harmful gases. Therefore, if the vegetable growers want to continue to flush chicken manure during this period, care must be taken to avoid causing harm to the vegetables.

First of all, chicken manure should be fully cooked before use. The temperature in the autumn began to fall. After the chicken manure was bought, the fermentation time should be slightly longer than that in the summer. Generally, it takes 30 days for the fall to fully decompose before the fermentation. When the flushing is applied, it must not be used excessively, and it must be avoided without complete decomposing. Chicken droppings into the shed cause the vegetables to burn. In addition, the high temperature produced by the chicken manure during the decomposed process can also kill pests such as cockroaches and cockroaches in the soil. If the chicken excrement has not been decomposed, these insect pests may be brought into the coop to harm the vegetables. Generally, chickens that have been fully decomposed have a dark brown appearance and a lighter ammonia smell. The appearance of unfammed chicken droppings is yellow-brown and has a strong odor and ammonia smell.
Followed by chicken manure after flushing should maintain good ventilation inside the shed. In autumn, the temperature at night is relatively low. In order to ensure that the temperature in the shed does not decrease, the vegetable grower often closes the greenhouse vent insulation at night. If chicken manure is flushed during this period, the ammonia produced in the soil during decomposition will easily accumulate smoked vegetables during the night. Therefore, within a few days after the application of chicken manure in the autumn, the ventilation conditions in the shed should be kept good. At night, when there is no low temperature, attention should be paid to the greenhouse outlet not being too tight, so as to prevent the accumulation of ammonia in the night shed from spreading out and causing damage to the vegetables.
The application of bio-fertilizers should also be taken into consideration. Even decomposed chicken manure inevitably contains some harmful substances that can cause harm to vegetables when it is rushed into the soil. With the appropriate amount of biological fertilizer, the biological bacteria in the biological fertilizer will decompose these harmful substances. Bio-fertilizers can also improve the soil structure, increase soil fertility, improve the quality of vegetables, and inhibit the effects of soil-borne diseases. If used in combination with chicken manure, the effect will be doubled.
