In recent years, some rice farmers have used chicken manure to produce green rice, which not only improves fertility but also reduces production costs. It also reduces the pollution of rice by chemical fertilizers, improves the quality of rice, and ensures people's physical and mental health. In addition to the harmless treatment of chicken manure in rice fields, attention should also be paid to the following issues. First, the amount of fertilizer: Rice in the application of chicken manure generally about 1,000 kg is appropriate. The application amount of chicken manure should also be increased or decreased according to the actual situation. Fresh chicken manure should be used less, Chen chicken manure can be used more, and the soil with good soil strength can be reduced, and the land with poor soil fertility should be increased. In addition, the amount of fertilizer depends on the varieties of rice, fertilizer-resistant varieties should be more, or less on some. Second, fertilization time and method: The chicken manure is best applied in the autumn before the site preparation, followed by deep turning or rotary tilling, deep or full-fertilizer. This will not only reduce nutrient losses, but also increase soil weathering time and improve the soil's ability to release nutrients. Since the time from autumn harvest to freezing is short, combined with the concentration of farm activities, the time for autumn fertilization and autumn soil preparation is shorter. The use of chicken manure for plots that were not in autumn can be carried out before the spring soil preparation. Applying warm chicken manure (or defrosted chicken manure) in paddy fields is better than using frozen chicken manure. When the frozen chicken manure was unloaded into the ground, when Janssa could not open it, the nutrients sank after falling snow or falling rain. No matter how seriously he cleaned the bottom of the pile, the “dump bottom†phenomenon would occur, ranging from leggy to weighty. No particles are received. Conditional farmers, the chicken manure is best to be mixed with some soil (can be more or less) after pouring back, and the bonded fecal pieces are shredded and scattered to facilitate uniform application. III. Irrigation Management: Rice fields applied to chicken manure should be combined with shallow water irrigation and intermittent irrigation or over-water irrigation. Shallow water irrigation is required in fields such as bubble fields, depressions, greening, fertilization, and pesticide application. When water is poured in fields or fields, there should be less water, and a depth of 1-2 cm can be used. The shallow water layer is conducive to raising the water temperature and the ground temperature, accelerating the process of soil reduction, increasing the solubility and absorbable quantity of phosphorus, potassium fertilizer and trace elements, accelerating the growth rate of rice, and facilitating the early growth. When spraying, about 3 cm of water is good. In the final period of effective labor, it is necessary to control the ineffective childbirth. Promotes deep stalked roots and prevents lodging. The meiosis of young ears should pay attention to using deep water to prevent cold damage. In the tillering, jointing, booting, and milk ripening periods, intermittent irrigation or irrigation with water is required. Some rice farmers after the weeding, the upper and lower drain mat is not good, resulting in long-term flow of rice fields. In this way, first, the paddy field maintains the water layer for a long time, and the soil temperature is low, which is not conducive to the growth of rice. Second, with the flow of water, the nutrients of the chicken manure are also lost, which severely reduces the utilization rate of fertilizers. Third, it is a waste of water, and it is unfavorable to save water. . In short, the use of chicken manure in paddy fields should be conducted in a proper amount, in time, in time, in order to be evenly distributed, to keep up with soil preparation, to keep irrigation water to a minimum, and to be scientific in management. This can reduce costs, increase production, eliminate pollution, optimize rice quality, and increase profits.
