Soil moisture temperature analyzer analysis of the effect of plastic film on peanut and peanut field

The promotion and application of film-covering technology has provided a very favorable cultivation technology for agricultural planting and production. In the peanut planting process, if the application of film-covering technology, not only can promote the growth and development of peanuts, increase the output of peanuts, but also can improve soil physics Traits, improve the content of available fertilizer in soil. For how to apply the coating technology and improve the economic benefits of peanuts, while increasing the output of peanuts and preventing the decrease of soil fertility, the application of organic fertilizers and inorganic fertilizers must be increased correspondingly, so as to achieve the purpose of high-yield fertility and realize a benign cycle. For soil-related indicators after coating, such as moisture temperature, etc., can be measured using a soil moisture temperature meter.

The growth of the plant body after the film was exposed was significantly faster than that of the cultivation. Generally about 7 days after emergence, 50% of the planted peanuts were blooming. The peanuts were barely seen in the uncovered peanuts, and the height of the main stem, the length of the lateral branches, and the length of the peanut were covered. The number of shoots, dry matter accumulation, leaf area, and other reproductive traits were all significantly different from those of open plants. Mushi ammonium bicarbonate, 17.5kg, superphosphate 59.5kg, and potassium chloride 15kg seedling stage, covered peanut dry matter per plant. The accumulation amount was 1.5g more than that of uncovered plants. The dry matter accumulation of peanut covered with a single seed was increased by 25.8g, and the growth rate was 42.6% at the ripening stage. The leaf area coefficient of coated peanut increased 0.51 than that of uncovered plants at seedling stage. The leaf area coefficient of covered peanuts increased by 1.44 compared with that of uncovered plants.

The effect of retroperitoneum on the growth and development of peanuts is obvious. What is the effect on soil-related parameters? Soil moisture temperature meter was used to measure the soil and it was found that the effect of the plastic film on the soil moisture, temperature and capacity of the soil covered by the film was obvious. According to the results of 14 measurements in 2006, except for special conditions such as post-rain and special drought, the soil moisture of the film was higher than that of the open plant. Under normal circumstances, the soil moisture content of the film was 5 cm higher than that of the open plant, and the average height was 2.1%. The soil layer was 1.1% higher at 10 cm and 0.9% higher at 20 cm. The warming effect of the membrane is mainly manifested in the early period of fertility. According to the ground temperature measurement of peanuts in the whole growing period in 2006, the soil temperature of 10cm deep, the film is more exposed than the exposed plant increased by 201.9 °C, an average daily temperature increase of 1.3 °C, which in May, an increase of 100.4 °C, daily temperature increase of 3.3 °C, in June At 55.9°C, the temperature is increased by 1.9°C per day, and then decreases month by month.

Through the detailed detection and analysis of the soil moisture temperature meter, the physical properties such as soil moisture, temperature, and bulk density were significantly improved after the membrane was covered. The temperature increase effect was mainly manifested in the early stage. After coating, soil erosion is reduced, and soil nutrients are relatively increased. Due to the increased consumption of minerals, the increase of mineralization intensity, and the acceleration of the conversion of delayed nutrients in soil, these may lead to a decrease in soil fertility. Considering maintaining soil strength, the application of organic fertilizer should be greater in the film-covered land than in open-air cultivation.
