Good soil permeability, good disease resistance of vegetables
Recently, many vegetable farmers have reported that they have begun to die again. The reporters found that the soil in the soft soil of the greenhouse was light, and the weight of the soil was too heavy and the permeability was poor. So how to improve the soil environment and enhance air permeability? Zhao Xinbin, Dongfang Village, Jitai Township, Shouguang City, has done a good job in increasing soil permeability. Although his family's shed has eighty-nine years old, the soil is still soft and airy. Master Zhao said that the maintenance of the soil environment is a long process of “cultivation of landâ€, but large amounts of chemical fertilizers, etc., will quickly lead to soil compaction, which will lead to poor growth of vegetable roots and wilting dead trees. Therefore, we must prevent the death of vegetables. Trees, soil permeability should be increased first. Summarizing measures to increase soil permeability, the reporter believes that the following points must be made: One is to pay attention to the deep turning of the soil. Before the vegetable is planted, it is necessary to deep-deep the soil, it is best to use a shovel to deepen 30 cm deep, and then use a rotary tiller to thin. This soil is not only breathable and permeable, but also conducive to deep rooting. The second is to pay attention to increase organic fertilizer. The lack of soil organic matter and excessive use of the amount of soil often result in soil compaction and poor air permeability. Therefore, the application of organic fertilizer is an important measure to improve soil permeability and change soil properties. It can be visualized that 15 to 25 square meters of chicken manure is applied per acre of the crops. If straw manure or rice husk manure is used, then soil improvement is better. When applying straw or rice husk manure, the application rate per mu can be increased to 35-40 square meters. Third, pay attention to changing cultivation methods. Changing the cultivation method can also improve the permeability of the soil. For example, ridge cultivation can be carried out in a furrow by watering, so the ridge surface has good air permeability and obvious temperature increase. The ditch planted vegetable root soil is often poured into the water, the permeability is poor, and it easily causes roots. Therefore, in vegetable cultivation, we must promote ridge cultivation. Conditional drip irrigation water is better. Fourth, pay attention to the use of biological bacterial fertilizer. After being applied into the soil, the biological bacteria in the biological fertilizer will multiply in the soil and play a role of activating and loosening the soil, which has a significant promoting effect on improving the soil structure and increasing the permeability of the soil. Can be 150-200 kg of biofertilizer per mu, or 25-30 kg per mu. Fifth, pay attention to reasonable watering. Water and gas are contradictory, water in the soil will be crowded out of the gas, will inevitably lead to poor permeability, so vegetables usually watering must pay attention to the amount of watering should not be too large, should not flood irrigation, conditions The best use of micro-irrigation in the area. After watering, when the soil is dry and wet, pay attention to timely cultivating loose soil, so that the air permeability of the soil will be good.
