The mulching technology plays an important role in modern agriculture and is widely used in the cultivation of various crops. Peanuts are also used for the cultivation of their coating technology. In order to understand the effects of the coating technology on soil properties, it is necessary to combine land use with land management to achieve the purpose of high yield and fertilizer. The physicochemical properties of the peanut covered soil were observed for 5 consecutive years. To make full use of the benefits of peanut-covered peanuts, while increasing peanut production and effectively preventing the decrease in soil fertility, the application levels of organic and inorganic fertilizers must be increased accordingly, in order to achieve the goal of high-yield fertility and ecologically sound circulation. The effect of the coating technology on the soil moisture in peanut field can be determined by using a portable soil moisture temperature measuring instrument.
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 determination of soil moisture temperature by the portable soil moisture temperature quick-measuring instrument found that the effect of the plastic film on the soil moisture, temperature and capacity of the coating was significant for the conservation of soil moisture. 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. According to the six determinations from the sowing date to the ripening date, the change in soil bulk density was: the coated film was reduced by 0.01-0.05 g/cm3 compared with the open air, and the peanut showed significant performance from the young fruit stage to the mature stage, indicating that the rainwater was reduced after the film was covered. The impact on the soil keeps the soil loose, the porosity increases, and the bulk density decreases.
The use of a portable soil moisture temperature quick-measuring instrument for the determination of soil moisture in the past five years and the determination of organic matter content in soil can be seen in the pre-harvest period of peanuts, due to moisture, temperature, ventilation and other conditions of the coated soil. The open air is more suitable for the activities of soil microorganisms. Therefore, the respiration intensity and ammoxidation intensity of the soil are enhanced, and the decomposition of soil organic matter is accelerated.
