Farmers often encounter greenhouses and green or red things on the ground in the orchard, which is what we often call moss or red moss. How did they grow up and what effect on the cultivation of vegetables and fruit trees?
When more and more roots of vegetables and fruit trees are found to be poorly grown, no matter how much fertilizer is added, the yield and quality are not improved. When moss or red moss grows on the surface, it tells us that the soil The trait has gone wrong.
First, the cause of soil long moss symptoms
1. The soil is acidic: long-term abuse of chemical fertilizers, ions remaining in the soil, slowly acidifying the soil;
2. The soil is humid and humid: the moss is a mossy animal, suitable for development in the water or the dampness of the ocean. It develops in wetlands, walls, wells, roof tiles and water. This is also the reason why the flood is easily flooded or the moss grows easily after the rain. After the heavy rain, it is easy to cause the backflow, and in addition to the continuous rainy weather, the moss will grow wild.
3, soil fertility is not good: fertilization does not mean that soil fertility is good, salinized, acidified soil, can not provide good nutrition and environment for plant growth.
4, poor drainage, soil moisture for a long time: in the absence of drainage facilities, fertilization should be watered, not fertilized, but also watered on the roots, the water in the soil is more difficult to evaporate;
5, the soil is tight, poor permeability: frequent watering, planting, fight drugs, trampled in the ground every day, the soil is not getting more and more tight;
Second, how to do long moss in the greenhouse
1. Pay more attention to the humidity of the soil, especially after the rainwater in the shed is poured, discharge the water as soon as possible.
2, choose more appropriate fertilizer application, especially phosphate fertilizer, should pay attention to the balance of soil nutrients.
3. Improve the quality of the soil, especially to maintain the acidity and alkalinity and permeability of the soil, and apply fine organic fertilizer and soil sanitizer to fine-tune the soil quality. On the one hand, it can activate the nutrients in the soil and improve the utilization of nutrients; on the other hand, Improve the development of plant roots and the receipt of nutrients.
4, timely ventilation and drainage, reduce the humidity on the surface of the soil, can reduce the occurrence of moss.
Third, how to deal with moss?
1. After the moss appears on the surface, it can be removed by evenly spraying the ash on the surface of the moss, and spreading it on the moss on the surface with grass ash;
2. Secondly, be careful not to overdo it when using the ash, excessive use will accelerate the process of soil salinization;
3. Copper in copper preparation can effectively kill moss. Copper sulphate is often used to remove moss from fish ponds and rice fields;
4. In the case of soil partial salinity, in the application of crops, it is conceivable to combine the prevention and control of seedling diseases, and use a copper preparation such as a basic copper sulfate suspension to spray off the moss.
