Treatment of soil disorders in facilities vegetables
1. The soil becomes compacted and the living soil becomes lighter. Due to the large amount of chemical fertilizers used, ignoring the application of organic fertilizers, the activity of soil fertility is declining, the organic matter is scarce, the permeability is reduced, and the aerobic microbial activity declines; deep turning is not achieved for a long time, the soil ripening is slow, and the plough layer of the greenhouse soil becomes shallow , resulting in soil compaction, vegetable root development, thus affecting the growth of vegetables. 2. Soil salinization. Due to over-application of chemical fertilizers in greenhouses, salt ions in the soil increased, pH value increased, soil salinization increased, impeding normal root water absorption and affecting plant growth. 3. Lack of trace elements. Due to continuous production for many years in greenhouses, trace elements such as zinc, boron, molybdenum, copper, and manganese in the soil are gradually declining. If they are not supplemented in time, it will cause serious shortage of trace elements in greenhouse soils, which will affect the growth and development of vegetables. 4. Accumulation of pests and diseases. After years of continuous cropping of greenhouse vegetables, insect pests and diseases have accumulated year after year in the soil, which has led to aggravation of diseases and insect pests, increased use of pesticides, and caused vegetable pollution. Second, the soil obstacles governance measures 1. Change the rotation. Do not grow the same kind of vegetables for many consecutive seasons. Such as melon vegetables and onion vegetables rotation, can reduce the occurrence of pests and diseases. 2. Add organic fertilizer. The application of organic fertilizers, especially the application of coarser fertilizers with more fiber, can improve the soil structure, enhance soil permeability and water retention and fertilizer retention, make the soil loose and fertile, prevent salt accumulation, promote the development of vegetable roots, and increase disease resistance. Relieve the degree of soil salinization. 3. Suitable leisure. The greenhouses that have been planted continuously for many years should be properly laid down and used to deepen the soil, eliminate the pests and diseases, and restore the soil. 4. Apply trace fertilizer. Micro-fertilizer as base fertilizer or top-dressing fertilizer can effectively solve the problem of insufficient trace elements in soil.
Laser Tape Measure
2 in 1, as its name, it is one product with traditional tape measure and
digital laser distance measurer. Laser measure tape can measure 40m with laser
