Huanghua Dongpei management grasp what?

In recent years from May to July every year, day lily "three diseases" (referring to leaf blight, leaf spot disease, and rust) are all in pandemic and seriously threaten the production of day lily. This year, the author's investigation found that: Huangcai field, which is poorly managed by Dongpei, is a pandemic disease in May, and its output is surprisingly wide. Huanghua Dongpei’s management is good and it is crucial to the epidemic of diseases. Dongpei mainly includes winter fertilizer and rhizosphere soil. Shi Dong Fei's time should stop growing on the ground part of lily, that is, when it withers after the fall of frost. Winter manure should be dominated by organic fertilizer, and the amount should be more. Applying 2500 kg per acre, it can be applied between the tussocks. It can also be applied at a depth of 18 centimeters and 15 centimeters deep at the 10-20 centimeters of the internodes of the rows. , for the day lily bolting reserve adequate nutrients. After the day lily enters the prolificacy period, the roots are well developed. If the roots are not cultivated, the root system will be exposed. Not only the absorption of fertilizer and drought resistance will be greatly weakened, but also the plant parts of the above ground will be underdeveloped and the yield will drop significantly. In the farmland, there is "Wenpeiyu, bud oil; Chunpeiyu, shaved bone." There is also the saying that "the winter tube culture is one inch high and the disease is three-points lighter the following year." China Agricultural Network Editor
