The root system is an important organ for plants to absorb nutrients from the soil. Intercropping has been particularly popular in recent years. In fruit trees and crop systems, fruit trees and crops interact through the absorption and utilization of light, moisture, and nutrients. This relationship is largely due to underground root systems. Caused by the interaction. Nowadays, we use root analysis system to study the effect of pitaya-soybean intercropping pattern on economic profit of orchards in order to provide scientific basis for reasonable intercropping of dragon fruit orchards.
In the past, dragon fruit was usually used for rational intercropping with crops such as peanuts, peppers, and melons. This would increase the efficiency of utilization of agricultural resources such as water and nutrients, increase the production of pitaya, and increase the income of farmers. This is a good precedent. The soybean has a short growth period, wide adaptability, simple production process, low investment, labor saving, easy management, and high efficiency. It is an ideal crop for land use, especially suitable for intercropping with other crops. The experiment was carried out in a dragon fruit orchard, and its natural conditions such as topography, landform and soil quality, and cultivation and management methods were basically the same. A total of 3 treatments are provided, namely, dragon fruit intercropping 1, dragon fruit intercropping 2, dragon fruit monocropping, randomized block design, and 3 repetitions. Each treatment area is 20m2. Soybeans were planted in June. Two rows of soybeans were planted in two rows of pitayas. The spacing between the rows was 35 cm × 15 cm. Clear tillage before sowing. The root system was sampled using a root analysis system for pitaya monocropping, crop monoculture, and compound systems, and the economic benefits of the intercropping system were analyzed during the harvest period.
We applied a root analysis system to study the effects of soybean and pitaya intercropping patterns on the ecological and economic benefits of pitaya orchards, and found that the roots of pitaya did not compete for nitrogen absorption in soybean roots and stimulated the nitrogen fixation activity of soybeans to atmospheric nitrogen. Further increase the soil nitrogen content, reduce the growth of weeds, create a good ecological environment for the growth and development of dragon fruit, promote the benign cycle of the orchard ecosystem, help the growth of dragon fruit, increase the yield, and improve the orchard Economic benefits.
